How do I convert UK shoe size to centimeters?

Select the relevant chart and enter a listed UK whole or half size. The tool returns the chart's approximate foot length. Because manufacturers differ, use your measured heel-to-toe length and the brand's own chart for a purchase decision.

Is foot length the same as the physical shoe length?

No. Foot length is the heel-to-toe measurement the size is intended to fit. The inside and outside dimensions of the shoe include fit allowance and depend on the model, shape and manufacturer.

Do UK men's and women's sizes have different technical lengths?

The ISO adult UK technical foot-length reference used here is the same for men and women. Individual brands can still use different lasts, widths and fit allowances.

What UK shoe size is 26 cm?

A 26 cm foot works out to UK 7.7 (260 × 3 ÷ 25.4 − 23), so the smallest listed size that covers it is UK 8 (26.25 cm reference). Measure both feet late in the day and use the longer one.

How do I measure my foot length for UK sizes?

Stand on paper with your heel against a wall, mark the tip of your longest toe, and measure from the wall to the mark in cm. Do it for both feet, preferably in the evening, and use the longer measurement. Enter that number in the foot-length converter to get your UK size.

Should I size up if I am between UK sizes?

Usually yes for length: choose the next half size whose reference length is at least your foot length, then check the brand chart. Each UK half size is 1/6 inch (about 4.2 mm), and the inside of the shoe adds its own toe allowance on top of the foot length.

Can I use this chart for UK children's shoes?

No. Children's UK numbering restarts across age bands, so a size without its age band is ambiguous. Use the chosen manufacturer's children chart.

Does this tool convert EU or US sizes?

No. Cross-system labels vary by manufacturer. This tool deliberately reports the UK-to-foot-length technical reference only.

Enter your UK shoe size in the input field.
The converter matches the entered whole or half size to this reference chart without silently rounding it.
The result shows the ISO technical foot-length reference in cm, mm and inches.
