Size charts for shoe stores on Shopify
Shoppers come from different sizing systems. Show US, UK and EU sizes side by side, with foot length so they can check their own measurement.
Shoe sizes are labels, not measurements, and every country uses different labels. US, UK and EU sizes don't convert one-to-one, US men's and women's sizes differ for the same foot, and two brands can put different labels on the same length.
That's why the most useful shoe size chart lists every system your customers use side by side, plus foot length, so a shopper can measure their own foot and check the number rather than trusting a label.
What your size chart needs
Sizes in every system you sell to
US, UK and EU shoe sizes don't line up exactly, and US men's and women's sizes differ. List each system in its own column.
Foot length
Foot length is the most reliable way to choose a shoe size, because it's a measurement rather than a label. Add it to the chart with a short how-to-measure note.
Boot measurements
For boots, add shaft height and shaft circumference so shoppers know where the boot will reach and whether it will fit their calf.
What to measure, product by product
The measurements in each of our free templates for shoe stores. Use them as a starting point, then replace the numbers with measurements from your own products.

| US Size | UK Size | EU Size | Foot Length (cm) |
|---|---|---|---|
| 7 | 6 | 40 | 25.0 |
| 8 | 7 | 41 | 25.7 |
| 9 | 8 | 42 | 26.4 |
| 10 | 9 | 43 | 27.1 |
| 11 | 10 | 44 | 27.8 |
| 12 | 11 | 45 | 28.6 |
Measurements that matter
The distance from the back of the heel to the tip of the longest toe, the basis of shoe sizing.
How tall the upper part of a boot is, which tells customers where the boot will reach on the leg.
The measurement around the widest part of a boot's shaft, important for fitting the calf.
How high the heel of a shoe raises the back of the foot.
The unit of European shoe sizes: two thirds of a centimetre.
The unit behind US and UK shoe sizes: one third of an inch.
Common mistakes to avoid
Only your own country's sizes
A shopper in the UK reading a US-only chart has to convert it themselves, often with a different conversion table from yours. List each system in its own column.
Leaving out foot length
Without foot length, shoppers can only compare labels. With it, they can measure their foot and choose with confidence.
Converting size codes as numbers
A size chart that switches cm to inches must leave the US, UK and EU size columns alone. Converting "EU 42" as if it were 42 cm produces nonsense.
One chart for every style
Boots, trainers and sandals from the same brand can fit differently. If they do, give each its own chart, or add a fit note.

Can I use one conversion chart for every brand?
It's a reasonable starting point, but brands differ by up to half a size. If you sell several brands, a chart per brand with foot length is more accurate.
Should I list men's and women's sizes together?
If the product is unisex, yes: show US men's and US women's columns, since US women's sizes run about 1.5 sizes above men's for the same foot.
How should customers measure their feet?
Stand on a sheet of paper with the heel against a wall, mark the tip of the longest toe, and measure from the wall to the mark. Measure both feet and use the longer one. Feet swell slightly during the day, so measuring in the afternoon or evening gives a more realistic number.
What should a customer do if they're between sizes?
The usual advice is to choose the larger size, especially for closed shoes and boots. If a style runs small or large, say so in a fit note so shoppers can adjust.
Is foot length the same as insole length?
No. A shoe's insole is a little longer than the foot it fits, to leave room for the toes. Label the column clearly so shoppers know whether to compare it with their foot.
Do kids' shoes need their own chart?
Yes. US children's sizes run up to 13 and then start again at 1 for older children, so they don't line up with adult sizes. A kids' chart with foot length is clearest.
