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

Often it just consists of a number indicating the length because many shoemakers only provide a standard width for economic reasons.

There are several different shoe-size systems that are used worldwide. These systems differ in what they measure, what unit of measurement they use, and where the size 0 (or 1) is positioned. Only a few systems also take the width of the feet into account. Some regions use different shoe-size systems for different types of shoes (e.g., men's, women's, children's, sport, or safety shoes).


Deriving the shoe size

Foot versus shoe and last

The length of a foot is commonly defined as the distance between two parallel lines that are perpendicular to the foot and in contact with the most prominent toe and the most prominent part of the heel. Foot length is measured with the subject standing barefoot and the weight of the body equally distributed on both feet.

The size of the left and right foot is often slightly different. In this case, both feet are measured, and the shoe size is based upon the larger foot.

Each size of shoe is suitable for a small interval of foot lengths. The inner cavity of a shoe must typically be 15–20 mm (0.6–0.8 in) longer than the foot, but this relation varies between different types of shoes.

There are three characteristic lengths that a shoe-size system can refer to:

All these measures differ substantially from one another for the same shoe.

Length unit

Sizing systems also differ in what units of measurement they use. This also results in different increments between shoe sizes because usually, only "full" or "half" sizes are made.

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

Due to the different units of measurements, converting between different sizing systems results in round-off errors as well as unusual sizes such as "10⅔".

Zero point

The sizing systems also place size 0 (or 1) at different locations:

Width designators

Some systems also include the width of a foot. There are different methods indicating the width:

The exact foot width for which these sizes are suitable can vary significantly between manufacturers. The A-E width indicators used by some US and UK shoe manufacturers are typically based on the width of the foot, and common step sizes are 1/16 of an inch.

Common sizing systems


The International Standard is ISO 9407:1991, Shoe sizes—Mondopoint system of sizing and marking,[2] that recommend a shoe-size system known as Mondopoint.

It is based on the mean foot length and width for which the shoe is suitable, measured in millimetres. A shoe size of 280/110 indicates a mean foot length of 280 millimetres (11 in) and width of 110 millimetres (4.3 in).

Because Mondopoint also takes the foot width into account, it allows for better fitting than most other systems. It is, therefore, used by NATO and other military services.

European standard EN 13402, used also for clothes, recommends, instead, that shoes be labelled with the interval of foot lengths for which they are suitable, measured in centimetres.

United Kingdom and Ireland

Shoe size in the United Kingdom (British size) is based on the length of the last, measured in barleycorn (approx 1/3 inch) starting from the smallest practical size, which is size zero. It is not formally standardised.

A child's size zero is equivalent to a hand (4 in, 12 barleycorns or 10.16 cm), and the sizes go up to size 13½ (8½ in or 21.59 cm). Thus, the calculation for a child shoe size in the UK is:

An adult size one is then the next size up (8⅔ in or 22.01 cm) and each size up continues the progression in barleycorns.[3] The calculation for an adult shoe size in the UK is thus:

United States and Canada

In North America, there are different systems that are used concurrently. The size indications are usually similar but not exactly equivalent, especially with athletic shoes at extreme sizes.


The traditional system is similar to English sizes but start counting at one rather than zero, so equivalent sizes are one greater. (This is similar to the way that floors in buildings are numbered from one rather from zero (ground) in these regions).

So the calculation for a male shoe size in the USA or Canada is:

[citation needed]

Women's sizes are almost always determined with the "common" scale, in which women's sizes are equal to men's sizes plus 1.5 (for example, a men's 10.5 is a women's 12). In other words:

In the less popular scale, known as the "standard" or "FIA" (Footwear Industries of America) scale, women's sizes are men's sizes plus 1 (so a men's 10.5 is a women's 11.5).


Children's sizes are equal to men's sizes plus 12.33. Thus, girls' and boys' sizes do not differ, even though men's and women's do.

Children's shoe stores in the United States use a sizing scheme which ends at 13, after which it starts at 1 again as adult sizes.

Brannock Device

A slightly different sizing method is based on a measurement device designed by shoe seller Charles Brannock.Many are now found in shoe stores. Men's size 1 is equivalent to a foot's length of 7 ⅔ in;[4] women's sizes are one size up.

[citation needed]

The method also measures the length of the distance of the heel and the widest point of the foot. For that purpose, the device has another, shorter scale at the side of the foot. If this scale indicates a larger size, it is taken in place of the foot's length.[5]

For children's sizes, additional wiggle room is added to allow for growth.[5]

The device also measures the width of the foot and assigns it designations of AAA, AA, A, B, C, D, E, EE, or EEE. The widths are 1/16 in apart and differ by shoe length.[4]

Athletic shoes

Some makers of athletic shoes, such as Nike, Reebok, or Fila, use an increment of 5 mm instead of half a barleycorn (4.23 mm)[6] As with other systems, women's sizes are one size up.

male shoe size (athletic) = foot length in centimetres − 18
female shoe size (athletic) = foot length in centimetres − 17

There are different sizes for children's and youths' shoes, for example, Nike uses the following:

shoe size (children) = foot length in centimetres − 6
shoe size (youth) = foot length in centimetres − 19

It is obvious that due to the different increments, the sizes can be similar to “normal” US sizes only for medium shoe sizes. For shoes that are larger or smaller, the sizes deviate substantially.


[citation needed]

Continental Europe

The Continental European system is used in France, Germany,[7] Italy, Spain,[8] and most other continental European countries.

In this system, the shoe size is the length of the last, expressed in Paris points, for both genders and for adults and children alike. Because a Paris point is ⅔ of a centimetre, the formula is as follow:

Based on foot length, one must first add about 1.5 cm.


The Asian system is based on metric measurements and standardised as JIS S 5037:1998, CNS 4800, S 1093, or KS M 6681. Foot length and girth are taken into account.[9]

The foot length is indicated in centimetres; an increment of 5 mm is used. This system was also used in the GDR.

The length is followed by designators for girth (A, B, C, D, E, EE, EEE, EEEE, F, G), which is taken from a table indexed to girth and length. There are different tables for men's, women's, and children's (less than 12 years of age) shoes. The tables also include the width as supplemental indications. Not all designators are used for all genders and in all countries. For example, the largest girth for women in China is EEEE, whereas in Japan, it is F.

In Japan, one maker also adds an indication for the foot width: N (narrow), M (medium), and W (wide).[10]

Shoe size comparison

Please, note that the following tables indicate theoretical sizes calculated from the standards and information given above. Differences between these tables and makers' tables or other tables found on the Web are usually due to the following factors:

Further, some tables available on the Web simply contain errors. For example, the wiggle room or different zero point is not taken into account, or tables based on different U.S. systems (traditional and athletic) are simply combined although they are incompatible.


Example: A child's foot that is 185 millimetres (7.3 in) long requires a shoe that is about 15 millimetres (0.59 in) longer. The inner length of 200 millimetres (7.9 in) is EU shoe size 30 or UK size 11.5.




International ShoeSize Chart Notes


Other Shoe Size Web Sites

A good site: Human Foot Morphology. Studies Japanese feet, but seems generally applicable. Also foot measurements.
When measuring feet for shoe size, measure to the longest toe. The longest is not always the big toe. I couldn't find any data on this other than Toe Size Poll.

According to Extraordinary Origins of Everyday Things, shoe sizes were first standardized in 1305 by Britain's King Edward I. An inch was defined as the length of three contiguous dried barleycorns. A common children's shoe size was 13 barleycorns, hence the size 13. From Origins at Happy Woman magazine.

Most business sites have poorly designed shoe size tables, that are prone to user errors and result in high return rates and a loss of repeat business. Bata had some well designed pages, but is now reorganizing its site so I can no longer point to specific links, with the exception of one great diagram in an Acrobat PDF file: Bata Comparative Shoe Size Chart.
(I am not endorsing products of any companies, or the contents of the tables. I am just noting the page is well structured and is much better than most.)

What is the Largest Shoe Size?

I don't know, but Shaq (NBA Basketball player Shaquille O'Neal) wears a 22G shoe. Here is his shoe size growth chart.
This shoe in the Philippine Shoe Capital,
Marikina City is 5.5 meters/16.5 feet (French size 273).
This shoe in
Hungary is size 217 (Euro system) or 145 cm. = 1.45 meters = 4.5 feet.
Zappos in the online Shoppes at Wellington Square carries a U.S. men's size
18EEEEE shoe.
Bill Clinton and Abraham Lincoln were the presidents with the biggest feet. Both wore size 13 shoes. Clinton is 13C.

Industry Notes

If you are looking for FIA (Footwear Industries of America, for information on the FIA scale, it is no longer there. In August 2000, the American Apparel & Footwear Association (AAFA) resulted from the merger of the two trade associations: the American Apparel and Manufacturers Association and Footwear Industries of America.

(Clearly these guys don't understand the web. Otherwise they wouldn't have just abandoned their web address, making it hard for anyone to find their new home...)

What Does I18n Guy Wear?

The I18n Guy wears New Balance running shoes. I wear them every day, snow, sleet or rain, and have had the same pair for several years now. Actually, I am tired of them, but they refuse to die. I don't understand how New Balance stays in business. Previously I wore Converse sneaks and replaced them every 6 months since they wore out quickly. (No, New Balance doesn't give me a commission!)

Triathlonit Suomessa

Triathlon in Finland

Ulkoministeri Alexander Stubb pisti kuntonsa perusteelliseen testiin sunnuntaina.

Hän osallistui triathlonin täysmatkojen EM-kilpailuun Frankfurtissa ja teki mainion loppuajan 10.35.00.
"Mahtava fiilis. Koko matkan ajan oli mahtava tunnelma, jota eivät vähentäneet sadat tuhannet katsojat reitin varrella.

Tämä jää kokemuksena mieleen loppuelämäksi", Stubb totesi.


Suomella on tod näk maailman kovakuntoisin ulkoministeri Telluksella tällä haavaa.

Triathlonin SM-kilpailuissa tuolla ajalla olisi sijoitettu vuonna 2008 sijalle 9 ja voitettu naisten sarja.

Kuntosarjassa oltaisiin oltu toinen, 2 minuutin päässä kullasta.

Vuonna 2007 Stubb olisi ollut 17. ja voitettu naisten sarja. Vuonna 2006 kahdeksas. Vuonna 2005 yhdeksäs, naisissa 1. Vuonna 2004 sijalla 24.

WIKIPEDIA: Triathlon on uinnin, pyöräilyn ja juoksun yhdistelmälaji.

Tärkeimmät triathlon-matkat ovat:


Triathlon on syntynyt Kaliforniassa 1970-luvun loppupuolella. Aluksi kilpailumatkat olivat nykyistä huomattavasti lyhyempiä eikä matkan eri osuuksien pituuksia oltu määritelty tarkkaan. Eri yhteydessä matkat poikkesivat toisistaan huomattavasti.

Kun vuonna 1978 Havaijilla järjestettiin ensimmäinen Ironman- eli Teräsmies-kilpailu, se saavutti muutaman vuoden kuluessa suuren näkyvyyden ja sitä kautta laji kasvatti huomattavasti suosiotaan. Siitä asti triathlonin oikeimpana pituutena on pidetty juuri Teräsmies-kisan matkaa, jossa kilpailumatkat ovat 3,8 kilometriä uintia, 180 kilometriä pyöräilyä ja 42 195 metriä juoksua, eli maratonin verran.

Triathlon hyväksyttiin olympialiikkeeseen vuonna 1994 ja se oli ensimmäistä kertaa mukana vuoden 2000 kisoissa Sydneyssä. Olympialaisissa kilpaillaan neljäsosamatkoilla. Ensimmäiset kultamitalistit olivat Kanadan Simon Whitfield ja Sveitsin Brigitte McMahon.

Triathlon Suomessa

Triathlon rantautui Suomeen 1980-luvulla, ensimmäiset kilpailut käytiin Joroisissa 1983. Ensimmäinen suomalainen teräsmies oli Magnus Lönnqvist, joka voidaan pitää suomalaisen triathlonin edelläkävijänä. Menestynein suomalainen on Pauli Kiuru, joka oli parhaimmillaan 2. Havaijin Ironman-kilpailussa. 2000 luvun valovoimaisimmat Suomalaistähdet ovat Mika Luoto (2002 Hawaiji 8. sija) ja Tom Söderdahl (2005 Hawaiji 8. sija). Triathlon koki Suomessa suuren "buumin" 80-luvun lopussa ja 90-luvun alussa. Harrastajamäärät olivat melko suuria, mutta 90-luvun puolivälissä harrastajamäärät putosivat selkeästi mutta lähtivät uuteen nousuun 2000 luvun alkupuolella.

Triathlonin kattojärjestönä toimii Suomen Triathlonliitto (
