How the Clarks Foot Size Calculator Works

The Clarks Foot Size Calculator works in 4 steps: measure on the gauge, read the length, read the width and match the 2 numbers to a size. Press a step to see that part of the gauge, move the 2 sliders, then send the numbers to the calculator at the top of the page.

↕ 150↔ 110

Measure

Stand the child on the gauge with the heel in the heel cup.

The Clarks Foot Gauge has 2 scales. The length scale runs from 97 to 281 and the width scale runs from 67 to 227. Gauge numbers are Clarks scale readings, not millimetres. The Clarks Foot Gauge Calculator looks up each length and width pair in a table of Clarks gauge results and returns a UK shoe size with a width fitting letter, such as 3.5 F. Use the Toddler guide for first walkers and the Junior guide for older children.

Clarks UK, US and EU Shoe Size Conversion

Clarks shoe size conversion lines up 3 scales by foot length: a women's UK 5 is a US 7 and an EU 38, and a men's UK 8 is a US 9 and an EU 42. Move the cursor to read UK, US and EU sizes at the same point.

UK
US
EU

UK shoe sizing and US shoe sizing both step in half sizes of 4.2 mm (1/6 inch). EU shoe sizing steps in Paris points of 6.7 mm (2/3 cm), so EU sizes do not line up with every UK half size. Ireland and the United Kingdom use UK sizes. The United States uses US sizes, and the European Union uses EU sizes. The Clarks Size Chart UK EU US shows all 3 sizes for shoppers in all 4 regions.

Clarks Shoe Sizes in CM and MM

Clarks shoe sizes in cm and mm run from 21.6 cm (216 mm) for a women's US 5 to 31.4 cm (314 mm) for a men's US 15. Type a foot length in centimeters, millimetres or inches to see it on the ruler and get the nearest Clarks size.

Centimeters

Inches

One centimeter equals 10 millimetres, and one inch equals 2.54 centimeters. A foot length of 23.5 cm is 235 mm and 9.25 in, which is a women's UK 5. A foot length measurement in cm is the same number the Clarks Adult Footwear Size Chart lists, so no conversion step is needed for adults. Children's Clarks Foot Gauge numbers are not centimeters or millimetres, so use the calculator for gauge numbers.

How to Measure Your Feet at Home

To measure your feet at home, stand on paper against a wall, mark the longest toe and measure from the wall to the mark. The 5 steps below take about 5 minutes with a sheet of A4 paper, a pencil and a ruler.

Left 23.4 cm · Right 23.7 cm → use 23.7 cm

Step 1 of 5

Tape a sheet of A4 paper to a hard floor, with one short edge touching a wall.

Measure in the evening, when feet are at their largest size of the day. Wear the socks worn with the shoes. Measure both feet and use the bigger number for the Clarks Shoe Size Conversion. A Clarks fitting appointment gives a store measurement, if the 2 home readings differ by more than 5 mm (0.2 in).

Other Shoe Brands to Clarks Size Converter

The other shoe brands to Clarks size converter turns the size on another brand's label into a Clarks UK, EU and US size, then moves it a half size up or down to match how that shoe fits. Pick the size system on the label, the size and the fit.

How does that shoe fit?

Shoe brands build shoes on different lasts, so the same printed size fits differently. Choose a half size up in Clarks, if the other brand feels tight. Choose a half size down, if the other brand feels loose. Clarks makes most adult styles in Narrow Fit, Standard Fit, Wide Fit and Extra Wide Fit, and many brands make one width only.

The recommended Clarks size is the smallest size whose foot length is equal to or longer than the measured foot, in the width fitting that matches the foot shape. Move the slider to the foot length and pick a foot shape.

Foot shape

Choose the next half size up, if a foot sits between 2 sizes. A shoe needs about 1 to 1.5 cm (0.4 to 0.6 in) of space past the longest toe for walking. Clarks Code shoes use impact absorbing technology, and the size rule stays the same for Clarks Code styles. A Clarks fitting appointment checks length, width and grip in store.

Tips for Measuring Foot Length

There are 6 tips for measuring foot length: measure late in the day, stand up, wear the right socks, measure both feet, hold the pencil upright and measure again. Tick each tip as you do it.

Tick each tip as you do it.

Measure a child's feet every 6 to 8 weeks up to age 3 and every 3 months after that, at home or at a Clarks School Fittings appointment.
