Clarks Shoe Size Chart

Clarks's own published size chart, covering a 23.7cm to 31.4cm foot, with 3 real width fittings rather than length alone, including a children's chart Clarks publishes itself. Every figure below is keyed to a measured foot length rather than converted from another size number. Open the calculator with Clarks selected to read it against all 35 brands at once.

Does Clarks run small?

Yes. By its own size chart, Clarks runs half a size to a full size small in both men's and women's sizes. A 24 cm foot is a women's US 7 in 16 of 34 other brands' charts, and a US 8 in Clarks. Charts show how a brand means its sizes to fit, not how any one shoe feels, so read Clarks's own fit advice below as well.

Foot length	Clarks	Most common in other brands
Men's, 25.5 cm	US 8.5	US 7.5 (21 of 34)
Men's, 27 cm	US 10	US 9 (23 of 34)
Men's, 28.5 cm	US 11.5	US 10.5 (20 of 34)
Women's, 23 cm	US 7	US 6 (15 of 33)
Women's, 24 cm	US 8	US 7 (16 of 34)
Women's, 25 cm	US 9	US 8 (16 of 34)

How this is worked out: every foot length from 25 to 29 cm (men's) and 22.5 to 26 cm (women's), in 1 mm steps, is read against Clarks's chart and the other 34 brands' charts the way the calculator reads them, rounding up between sizes. The answer is the average gap between Clarks's size and the size the other brands give most often. See the methodology.

Clarks width chart

Clarks publishes 3 men's and 4 women's width fittings. The standard fitting is G in men's and D in women's.

Men's fittings

Fitting	What Clarks calls it	Note
G	Standard Fit	Clarks' standard men's fitting, which suits most wearers
H	Wide Fit
XW	Extra Wide Fit

Women's fittings

Fitting	What Clarks calls it	Note
C	Narrow Fit
D	Standard Fit	Clarks' standard women's fitting, which suits most wearers
E	Wide Fit
EE	Extra Wide Fit

Not every model is made in every fitting. Enter a forefoot width in the calculator and it returns Clarks' own fitting for your foot. The width chart compares fittings across brands, and the wide-feet guide shows how to tell whether your foot is wide.

How to measure for Clarks

Clarks recommends measuring in millimeters from the back of the heel to the tip of the longest toe (which is not always the big toe), and measuring both feet and using the longer one. Note that Clarks prints its own 'Clarks EU' size on the box, which differs from the standard EU size at several points -- for example a men's UK 10 is a Clarks EU 44.5 but a standard EU 45. The EU figures shown here are Clarks' own.

Clarks fit guidance

Clarks is one of the few mainstream brands offering real width fittings across much of its range, so if the length is right but the shoe feels tight or loose across the foot, changing fitting is the answer rather than changing size. Clarks' own standard fitting is G for men and D for women. Men's runs G (standard), H (wide) and XW (extra wide); women's runs C (narrow), D (standard), E (wide) and EE (extra wide). Note these are Clarks' product fittings. On the generic UK letter scale a G reads as 'wide', which is why a Clarks G is not the same claim as a G elsewhere. Clarks' men's and women's charts also share the same UK-size-to-foot-length scale; they simply cover different parts of it. Clarks children's shoes are stamped with their UK size, which is the column to match against a pair you already own. Children's widths use a different letter scale from the adult range. F is the children's standard fitting, with E narrow, G wide and H extra wide, so a kids' G is not the same claim as the men's G.
