A shoe size is an indication of the fitting size of a shoe for a person.

In that location are a number of different shoe-size systems used worldwide. While all shoe sizes use a number to indicate the length of the shoe, they differ in exactly what they measure, what unit of measurement of measurement they use, and where the size 0 (or 1) is positioned. Some systems also point the shoe width, sometimes also every bit a number, just in many cases past one or more than letters. Some regions use different shoe-size systems for dissimilar types of shoes (eastward.yard. men'southward, women'due south, children's, sport, and safety shoes). This commodity sets out several complexities in the definition of shoe sizes. In exercise, shoes should be tried on for size and fit before they are purchased.

Deriving the shoe size [edit]

Foot versus shoe and last [edit]

The length of a person's foot is usually defined equally the altitude betwixt two parallel lines that are perpendicular to the foot and in contact with the most prominent toe and the virtually prominent part of the heel. Pes length is measured with the subject standing barefoot and the weight of the body equally distributed between both feet.

The sizes of the left and right feet are often slightly different. In this example, both feet are measured, and purchasers of mass-produced shoes are brash to purchase a shoe size based on the larger pes, as virtually retailers do non sell pairs of shoes in not-matching sizes.

Each size of shoe is considered suitable for a small interval of foot lengths, typically limited by half-bespeak of the shoe size organization.

A shoe-size system can refer to three characteristic lengths:

  • The median length of feet for which a shoe is suitable. For customers, this measure has the advantage of being direct related to their body measures. It applies equally to any type, form, or cloth of shoe. Withal, this measure out is less popular with manufacturers,[ commendation needed ] because it requires them to test carefully for each new shoe model, for which range of foot sizes information technology is recommendable. It puts on the manufacturer the burden of ensuring that the shoe will fit a foot of a given length.
  • The length of the inner crenel of the shoe. This measure has the advantage that it tin can be measured easily on the finished product. However, information technology will vary with manufacturing tolerances and merely gives the customer very crude data nigh the range of foot sizes for which the shoe is suitable.
  • The length of the "concluding", the foot-shaped template over which the shoe is manufactured. This measure out is the easiest one for the manufacturer to use, because it identifies only the tool used to produce the shoe. It makes no promise almost manufacturing tolerances or for what size of foot the shoe is really suitable. Information technology leaves all responsibleness and chance of choosing the right size with the customer. Farther, the terminal can be measured in several different ways, resulting in different measurements.[1]

All these measures differ essentially from one some other for the same shoe. For example, the inner cavity of a shoe must typically be 15 mm longer than the human foot, and the shoe last would be ii size points larger than the foot, but this varies between different types of shoes and the shoe size arrangement used. The typical range lies between 1two to 23 inch (12.7 to xvi.9 mm) for the UK/Usa size system and 43 to five3  cm (13.iii to xvi.7 mm) for the European size system, but may extend to 14 to 34 inch (6.4 to 19.1 mm) and 23 to 63  cm (6.vii to twenty.0 mm).

Length [edit]

Sizing systems likewise differ in the units of measurement they use. This also results in different increments between shoe sizes, because ordinarily only "total" or "half" sizes are made.

The following length units are commonly used today to ascertain shoe-size systems:

  • The Paris signal equates to 23 centimetre (6.67 mm; 0.26 in). Whole sizes are incremented by 1 Paris bespeak; this corresponds to 3.33 millimetres (0.131 in) between one-half sizes. This unit of measurement is commonly used in Continental Europe, and Russia and sometime USSR countries.
  • The barleycorn is an quondam English unit that equates to 13 inch (8.47 mm). This is the basis for current United kingdom of great britain and northern ireland and Due north American shoe sizes, with the largest shoe size taken as twelve inches (a size 12) i.east. 30.five cm, then counting backwards in barleycorn units, and then a size 11 is eleven.67 inches or 29.six cm.
  • Metric measurements in millimetres (mm) or centimetres (CM), with intervals of 5 mm and 7.five mm are used in the international Mondopoint organisation (USSR/Russia and East Asia).

Since early 2000s, labels on the sports shoes typically include sizes measured in all four systems: European union, UK, US, and CM (Mondopoint).

Goose egg point [edit]

The sizing systems also place size 0 (or i) at different locations:

  • Size 0 every bit a foot's length of 0. The shoe size is directly proportional to the length of the pes in the chosen unit of measurement. Sizes of children'due south, men's, and women'south shoes, as well as sizes of unlike types of shoes, tin can be compared directly. This is used with the Mondopoint organization (USSR/Russia and Eastern asia).
  • Size 0 as the length of the shoe'due south inner cavity of 0. The shoe size is then direct proportional to the inner length of the shoe. This is used with systems that also take the measurement from the shoe. While sizes of children's, men'southward and women's shoes can be compared directly, this is not necessarily truthful for dissimilar types of shoes that require a different amount of "wiggle room" in the toe box. This is used with the Continental European system.
  • Size 0 (or one) can simply be simply a shoe of a given length. Typically this volition be the shortest length accounted applied; but this can exist dissimilar for children'due south, teenagers', men'south, and women's shoes - making information technology impossible to compare sizes. For example, a women's shoe at size 8 is a dissimilar length from a men'due south shoe at size 8 in the United states system, just not the British.

Width [edit]

Some systems also include the width of a foot (or the girth of a shoe final), but practice so in a diverseness of means:

  • Measured foot width in millimetres (mm) - this is done with the Mondopoint system.
  • Measured width every bit a letter (or combination of messages), which is taken from a tabular array (indexed to length and width/girth) or just assigned on an advert-hoc ground. Examples are (each starting with the narrowest width):
    • AAA, AA, A, B, C, D, E, EE, EEE is the typical North American system and follows the brannock device standards, per the system B is narrow, C is regular, D is medium, Eastward is wide, EE is actress broad and and then on.
    • 4A, 3A, 2A, A, B, C, D, E, 2E, 3E, 4E, 5E, 6E (variant Due north American).
    • In Japanese Mondopoint system the unlettered D size is the norm for men and B for women in its human foot circumference.
    • C, D, E, F, G, H (common UK; "medium" is usually F, but varies by manufacturer—makers Edward Green and Crockett & Jones, among others, use E instead, but one maker's E is not necessarily the aforementioned size every bit another's).
    • N (narrow), M (medium) or R (regular), W (wide).

The width for which these sizes are suitable can vary significantly between manufacturers. The A–Due east width indicators used by nigh American, Canadian, and some British shoe manufacturers are typically based on the width of the pes, and mutual step sizes are three16 inch (4.eight mm).

Difficulties [edit]

There could be differences betwixt diverse shoe size tables from shoe makers and shoe stores. They are usually due to the following factors:

  • Different methods of measuring the shoes, different manufacturing processes, or dissimilar allowances[1] fifty-fifty when the same system is used.
  • An indication in centimetres or inches tin can mean the length of the human foot or the length of the shoe's inner cavity.
  • Differing amounts of jerk room required for different sizes of shoes.
  • For wide anxiety, a shoe several sizes larger (and really too long) may exist required, and may also result in inconsistent size indications when different typical widths are attributed to specific shoe sizing systems.
  • Some tables for children accept future growth into account. The shoe size is then larger than what would correspond to the actual length of the pes.[two]

Conversion tables bachelor on the Web oftentimes contain obvious errors, not taking in to account different zero points or jerk room.

Although shoe size systems are not fully standardised, the ISO/TC 137 had released a technical specification ISO/TS 19407:2015 for converting shoe sizes beyond various local sizing systems. Even though trouble of converting shoe sizes accurately has even so to be fully resolved, this standard serves every bit "a practiced compromise solution" for shoe-buyers.[3] [4]

Common sizing systems [edit]

United Kingdom [edit]

Shoe size in the U.k., Republic of ireland, India, Pakistan and South Africa is based on the length of the final used to make the shoes, measured in barleycorns ( one3 inch) starting from the smallest size deemed practical, which is chosen size zero. It is non formally standardised. Note that the terminal is typically longer than the foot heel to toe length past 12 to 2iii in or 1+ 12 to 2 barleycorns, so to make up one's mind the shoe size based on actual foot length one must add 2 barleycorns.

A child'south size zero is equivalent to 4 inches (a hand = 12 barleycorns = 10.16 cm), and the sizes go upwards to size 13+ 12 (measuring 25+ 12 barleycorns, or 8+ one2 inches (21.59 cm)). Thus, the calculation for a children's shoe size in the United kingdom of great britain and northern ireland is:

child shoe size (barleycorns) = 3 × final length (in) − 12

equivalent to:

child shoe size (barleycorns) ≈ iii × foot length (in) − ten.

An adult size 1 is then the adjacent size up (26 barleycorns, or 8+ 2iii  in (22.01 cm)) and each size up continues the progression in barleycorns.[5] The calculation for an developed shoe size in the Britain is thus:

adult shoe size (barleycorns) = 3 × concluding length (in) − 25

equivalent to:

adult shoe size (barleycorns) ≈ three × foot length (in) − 23.

Although this sizing standard is nominally for both men and women, some manufacturers use different numbering for women'south United kingdom of great britain and northern ireland sizing.

In Commonwealth of australia and New Zealand, the U.k. system is followed for men and children's footwear. Women'due south footwear follows the US sizings.

In Mexico, shoes are sized either according to the foot length they are intended to fit, in cm, or alternatively to some other variation of the barleycorn arrangement, with sizes calculated approximately as:

developed shoe size (barleycorns) = 3 × concluding length (in) − 25+ 12

equivalent to:

adult shoe size (barleycorns) ≈ 3 × foot length (in) − 23+ 12 .

United States [edit]

In the United states and Canada, the traditional arrangement is similar to British merely at that place are different zilch points for children'due south, men's, and women's shoe sizes. The most mutual is the customary organisation where men'due south shoes is one size shorter than the UK equivalent, making a men's 13 in the US the same size as a men's 12 in the UK.

Customary [edit]

The customary arrangement is starting time by i4 barleycorn, or i12  in (2.12 mm), comparing to the UK sizes. The men'southward range starts at size 1, with aught point corresponding to the children'southward size 13 which equals 24+ threeiv barleycorns or 8+ 14 inches (xx.96 cm).

However nearly Usa manufacturers are using greater offsets, such as one2 and 1 barleycorns.[6] Therefore in current do, U.s.a. men's size ane equals 25 barleycorns, or 8+ 13  in (21.17 cm), then the adding for a male shoe size in the United States is:

male shoe size (barleycorns) = iii × last length (in) − 24

equivalent to:

male shoe size (barleycorns) ≈ iii × foot length (in) − 22.

In the "standard" or "FIA" (Footwear Industries of America) calibration, women'southward sizes are men'due south sizes plus 1 (so a men's 10+ ane2 is a women's xi+ 12 ):

female person shoe size (barleycorns) = 3 × concluding length (in) − 23

equivalent to:

female shoe size (barleycorns) ≈ iii × foot length (in) − 21.

There is also the "common" scale, where women'southward sizes are equal to men's sizes plus 1+ 1two .

Children's shoes showtime from size zero, which is equivalent to 3+ eleven12 inches (11+ 34 barleycorns = 99.48 mm), and cease at 13+ anetwo . Thus the formula for children's sizes in the US is

kid shoe size (barleycorns) = three × last length (in) − eleven 34

equivalent to:

child shoe size (barleycorns) ≈ 3 × foot length (in) − nine 34 .

Alternatively, a Mondopoint-based scale running from K4 to K13 and and so 1 to vii is in use.[seven] K4 to K9 are toddler sizes, K10 to K13 are pre-school and ane to 7 are grade school sizes.

Brannock Device [edit]

Brannock Device is a measuring instrument invented past Charles F. Brannock in 1925 and now plant in many shoe stores. The recent formula used by the Brannock device assumes a foot length of two barleycorns less than the length of the last; thus, men's size 1 is equivalent to a final's length of eight+ ane3  in (21.17 cm) and foot'south length of seven+ 2three  in (19.47 cm), and children's size i is equivalent to 4+ 14  in (10.eight cm) terminal'due south length and 3+ vii12  in (ix.one cm) foot'southward length.[eight] [9]

The device besides measures the length of the arch, or the distance between the heel and the ball (metatarsal head) of the human foot. For this measurement, the device has a shorter calibration at the instep of the foot with an indicator that slides into position. If this scale indicates a larger size, it is taken in identify of the foot'south length to ensure proper fitting.[2]

For children'due south sizes, additional wiggle room is added to allow for growth.[2]

The device also measures the width of the pes and assigns it designations of AAA, AA, A, B, C, D, E, EE, or EEE. The widths are 3/16 inches autonomously and differ past shoe length.[8]

Some shoe stores and medical professionals use optical 3D surface scanners to precisely measure the length and width of both feet and recommend the appropriate shoe model and size.[10]

Continental Europe [edit]

In the Continental European system, the shoe size is the length of the last, expressed in Paris points or 23  cm (vi.67 mm), for both sexes and for adults and children akin. Note that the last is typically longer than the foot heel to toe length by iv3  cm (13.33 mm) to v3  cm (sixteen.67 mm), or 2 to two+ 12 Paris points, and then to determine the shoe size based on actual foot length i must add 2 Paris points.

Because a Paris point is 2iii of a centimetre, the formula is every bit follows:

shoe size (Paris points) = iii2 × last length (cm)

equivalent to:

shoe size (Paris points) ≈ 32 × human foot length (cm) + 2.

The Continental European system is used in Austria, Kingdom of belgium, Denmark, France, Germany,[xi] Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Kingdom of spain,[12] Sweden, Switzerland, and most other continental European countries. It is likewise used in Heart Eastern countries (such equally Islamic republic of iran), Brazil—which uses the same method only subtracts 2 from the final result, in upshot measuring pes size instead of terminal size[ commendation needed ]—and, normally, Hong Kong. The system is sometimes described equally Stich size (from Pariser Stich, the German name for the Paris point), or Stichmaß size (from a Geman proper name of a micrometer for internal measurements).

Mondopoint [edit]

Measurement of foot length, width and perimeter (cirсumference) every bit divers in the Mondopoint standard

The Mondopoint shoe length system is widely used in sports industry to size athletic shoes, ski boots, skates, and pointe ballet shoes; information technology was as well adopted every bit the primary shoe sizing system in the Soviet Union,[13] Russia,[14] East Germany, Prc,[15] Japan, Taiwan, and S Korea, and every bit an optional system in Britain,[16] India,[17] United mexican states, and European countries. The Mondopoint organisation is also used by NATO and other military services.

The Mondopoint arrangement was introduced in the 1970s by International Standard ISO 2816:1973 "Fundamental characteristics of a organisation of shoe sizing to be known as Mondopoint" and ISO 3355:1975 "Shoe sizes – System of length grading (for utilize in the Mondopoint system)".[xviii] ISO 9407:2019, "Shoe sizes—Mondopoint arrangement of sizing and marking",[nineteen] is the current version of the standard.

The Mondopoint system is based on boilerplate foot length and foot width for which the shoe is suitable, measured in millimetres. The length of the foot is measured as horizontal distance betwixt the perpendiculars in contact with the cease of the most prominent toe and the most prominent function of the heel. The width of the human foot is measured as horizontal distance between vertical lines in contact with the first and fifth metatarsophalangeal joints. The perimeter of the pes is the length of foot circumference, measured with a flexible record at the same points as human foot width. The origin of the grade is zero.

The labeling typically includes foot length, followed by an optional foot width: a shoe size of 280/110 indicates a foot length of 280 millimetres (11.0 in) and width of 110 millimetres (4.3 in). Other customary markings, such as EU, UK and US sizes, may also be used.

Because Mondopoint takes the pes width into account, it allows for improve fitting than most other systems. A given shoe size shall fit every foot with indicated average measurements, and those differing by no more a one-half-footstep of the respective interval grid. Standard human foot lengths are defined with interval steps of 5 mm for casual footwear and steps of 7.five mm for specialty (protective) footwear. The standard is maintained by ISO Technical Committee 137 "Footwear sizing designations and marking systems."

E Asia [edit]

In Nihon, mainland Cathay, Taiwan, and Republic of korea, the Mondopoint system is used equally defined by national standard Japanese Industrial Standards (JIS) S 5037:1998 and its counterparts Guobiao (GB/T) 3293.one-1998, Chinese National Standard (CNS) 4800-S1093:2000 and Korean Standards Association (KS) M 6681:2007.

Foot length and girth (foot circumference) are taken into account.[20] The foot length is indicated in centimetres; an increment of v mm is used.

The length is followed by designators for girth (A, B, C, D, Eastward, EE, EEE, EEEE, F, M), which are specified in an indexed table equally pes circumference in millimetres for each given foot length; human foot width is besides included as supplemental information. At that place are dissimilar tables for men'due south, women's, and children's (less than 12 years of age) shoes. Not all designators are used for all genders and in all countries. For case, the largest girth for women in Taiwan is EEEE, whereas in Japan, information technology is F.

The foot length and width can also exist indicated in millimetres, separated by a slash or a hyphen.

Soviet Union (Russia, Commonwealth of Contained States) [edit]

Historically the Soviet Spousal relationship used the European (Paris point) system, but the Mondopoint metric organization was introduced in the 1980s by GOST 24382-80 "Sizes of Sport Shoes" (based on ISO 2816:1973) and GOST 11373-88 "Shoe Sizes" (based on ISO 3355:1975), and lately by GOST R 58149-2018 (based on ISO 9407:1991)

Standard metric human foot sizes can be converted to the nearest Paris indicate ( ii3  cm) sizes using approximate conversion tables; shoes are marked with both foot length in millimetres, as for pointe ballet shoe sizes, and final length in European Paris signal sizes (although such converted Stichmaß sizes may come one2 to 1 size smaller than comparable European-fabricated adult footwear, and up to 1+ 1ii sizes smaller for children's footwear, according to ISO 19407 shoe size definitions). Foot lengths are aligned to 5 mm intervals for sports and casual shoes, and vii.5 mm for protective/safety shoes. Optional pes width designations includes narrow, normal (medium or regular), and broad grades.

Baby sizes start at 16 (95 mm) and pre-schoolhouse kids at 23 (140 mm); schoolchildren sizes span 32 (202.5 mm) to 40 (255 mm) for girls and 32 to 44 (285 mm) for boys. Adult sizes bridge 33 (210 mm) to 44 for women and 38 (245 mm) to 48 (310 mm) for men.

ISO 19407 and shoe size conversion [edit]

ISO/TS 19407:2015 Footwear - Sizing - Conversion of sizing systems is a technical specification from International Standards Organization. It contains bones description and conversion tables for major shoe sizing systems [iii] including Mondopoint with length steps of 5 mm and 7.five mm, European Paris point arrangement, and UK 1iii -inch system. The standard has also been adopted as Russian GOST R 57425-2017.

The standard is maintained by ISO/TC 137, which also developed ISO/TS 19408:2015 Footwear - Sizing - Vocabulary and terminology; currently in development are companion standards ISO/TS 19409 "Footwear - Sizing - Measurement of terminal dimensions" and ISO/TS 19410 "Footwear - Sizing - Inshoe measurement".

Shoe sizing [edit]

The adult shoe sizes are calculated from typical final length, which is converted from foot length in mm by adding an allowance of two shoe sizes:

EUR shoe size = L + 2 × half dozen.6 6 ¯ 6.6 vi ¯ = iii 20 × L + 2 Britain shoe size = L + 2 × eight.4 6 ¯ 8.4 6 ¯ 25 = iii 25.4 × 50 23 {\displaystyle {\begin{aligned}{\text{EUR shoe size}}&={\frac {L+ii\times {half dozen.6{\bar {half-dozen}}}}{6.6{\bar {six}}}}={\frac {three}{20}}\times {L}+ii\\[3pt]{\text{United kingdom shoe size}}&={\frac {L+2\times {8.four{\bar {vi}}}}{8.four{\bar {6}}}}-25={\frac {iii}{25.4}}\times {L}-23\cease{aligned}}}

where L is pes length in mm.

Direct conversion betwixt developed UK, Continental European and Mondopoint shoe size systems is derived equally follows:

L = xx three × ( EUR shoe size two ) = 25.iv 3 × ( UK shoe size + 23 ) EUR shoe size = 1.27 × ( U.k. shoe size + 23 ) + 2 United kingdom shoe size = EUR shoe size 2 1.27 23 {\displaystyle {\begin{aligned}50&={\frac {xx}{3}}\times \left({\text{EUR shoe size}}-two\correct)={\frac {25.4}{3}}\times \left({\text{Britain shoe size}}+23\correct)\\[3pt]{\text{EUR shoe size}}&={1.27\times \left({\text{United kingdom of great britain and northern ireland shoe size}}+23\correct)}+2\\[3pt]{\text{United kingdom shoe size}}&={\frac {{\text{EUR shoe size}}-2}{1.27}}-23\end{aligned}}}

Using these formulas, the standard derives shoe size tables for adults and children, based on actual foot length measurement (insole) in millimetres. Typical terminal length ranges are also included (xiii to 25 mm over pes length for adults, 8% greater than pes length plus six mm for children).

Exact foot lengths may comprise repeating decimals considering the formulas include partitioning by 3; in practice, approximate interval steps of half-dozen.67 mm and 8.47 mm are used, and sizes are rounded to either 12 size indicate or closest matching Mondopoint size.

Size marking [edit]

It is recommended to mark include size marker in each of the iv sizing systems on the shoe label and on the package. The chief system used for manufacturing the shoe needs to exist placed first and emphasized with a boldface.

The standard includes quick conversion tables for developed shoe size marking; they provide matching sizes for shoes marked in Mondopoint, European, and U.k. systems. Converted values are rounded to a larger shoe size to increase comfort.
