Women’s Shoe Size Chart: US, UK and EU Sizes by Foot Length

A women’s shoe size chart depends on the brand. Per adidas’s chart (via evo), a 25 cm foot is a US women’s 8, UK 6.5, EU 40. Per Nike’s chart, the same US 8 is a UK 5.5 and EU 39; per Skechers, a UK 5 and EU 38. Measure your foot, then read the chart of the brand you’re buying.

Women’s sizes vary between brands more than men’s do. For the same US women’s size, the UK number can sit 1.5, 2.5 or 3 sizes lower depending on whose chart you read, and the EU number moves by up to two full sizes. That is why this guide gives each brand’s table separately: adidas with foot length in centimeters, Nike’s conversion with the men’s equivalent, and Skechers’s US/UK/EU table, plus measuring steps and the width letters. For every system on one page, see the shoe size conversion chart.

Women’s shoe size chart by foot length (per adidas, via evo)

adidas.com blocked automated access during research, so this table comes from the copy published by the retailer evo. The column alignment was rebuilt from flattened page text. In adidas sizing, US women’s equals US men’s plus 1.

Each half size adds 0.5 cm of foot length on this chart, and the EU column moves in thirds (36.7 is 36 2/3). For the rest of the brand’s sizing, see the adidas size chart.

Nike women’s shoe size conversion

Nike’s women’s chart converts US women’s to US men’s, UK and EU. In Nike sizing, US women’s equals US men’s plus 1.5, a bigger offset than adidas uses. The CM/JP column is a shoe size, not a foot length; Nike says so on the page.

Nike’s full chart runs from US women’s 3.5 to 22.5 and maps big-kid sizes 2Y to 7Y onto the smallest women’s sizes. Nike does publish inch values on its women’s page, but the page doesn’t show which inch value belongs to which size, so they are left out here rather than guessed.

Skechers women’s US, UK and EU conversion

Skechers’s women’s table has no foot-length column. It is unlabeled in the page text and read as women’s from its range.

Why women’s shoe sizes don’t match between brands

Here is the same US women’s size read off each brand’s chart. Every value is copied from the tables above.

A US women’s 8 lands on EU 38, 39 or 40 depending on the brand, and the UK figure ranges from 5 to 6.5. The US-to-UK gap is about 1.5 sizes at adidas, 2.5 at Nike and 3 at Skechers. Zappos’s general conversion adds a fourth reading: women’s 8 = UK 6 = EU 38–39, with a foot length of 9.5 inches (24.1 cm).

The practical rule: if you know your EU size in one brand, don’t carry that number to another brand. Measure your foot and find the length on the brand’s own chart, or use the brand’s own conversion if it doesn’t list length. Women’s boots follow the same logic; the women’s boots guide covers styles and fit by boot type.

How to measure your foot

Nike’s method is the same for women’s and men’s shoes:

1. Tape paper to a hard floor.
2. Stand with one foot on the paper and your weight balanced.
3. Have someone mark the tip of your big toe and the outermost point of your heel, with the pen held straight down.
4. Measure between the marks.
5. Repeat on the other foot and use the longer number.
6. If you fall between sizes, Nike recommends sizing up.

Zappos suggests measuring while standing and wearing the socks you’ll wear with the shoes, and notes that charts are a guide only because sizing varies by style and manufacturer. A soft tape measure or a ruler gives you the length; to read it in centimeters against the adidas table, measure in cm directly.

Women’s shoe width chart

The standard women’s width is B, while for men it is D. That means a D width is “wide” in women’s shoes and “standard” in men’s, which trips up anyone shopping across both sections.

Skechers says its “Women’s Wide Fit” is a W or D width. Nike describes width as extra room instead: Wide has about 1/4 inch (6.35 mm) more toe-box room than regular, and Extra Wide about 1/2 inch (1.27 cm) more. The combination Brannock Device lists women’s widths from 4A to 4E.

Shopping a new brand: a quick method

Because the conversions don’t agree, the safest way to buy a brand you haven’t worn is to work from length, not from a number you already know:

1. Measure your longer foot in centimeters, standing, in the socks you plan to wear.
2. If the brand lists foot length, pick the size that matches that length. If you land between two sizes, Nike’s advice is to size up.
3. If the brand lists only a US/UK/EU conversion, as Skechers does, start from your US women’s size and read across its own table rather than another brand’s.
4. Check the width letter separately. A B is standard; a D is wide in women’s sizing.
5. Ignore the CM figure printed on a box or label when comparing with your foot length. Nike says that number is a shoe size, not a foot measurement.

The same steps work for secondhand shoes, where the label may show only one sizing system. Read the size in whatever system is printed, then check it against that brand’s chart.

Women’s to men’s shoe sizes

Converting women’s to men’s means subtracting, but by how much depends on the brand: 1.5 at Nike, 1 at adidas (via evo) and in the Brannock formula. A women’s 9 is a men’s 7.5 at Nike and a men’s 8 at adidas. Read the women’s to men’s shoe size guide for the full conversion, or the men’s shoe size chart for Nike’s men’s foot lengths in inches.

Smaller sizes overlap with big-kid shoes. Per Nike, a 3.5Y matches a women’s 5 and a 7Y matches a women’s 8.5; the kids’ shoe size chart has the full big-kid run.

The verdict

Women’s shoe sizes are the least consistent across brands, so the chart you read matters more than the number you remember. The adidas table (via evo) is the most useful single reference because it pairs every half size from 5 to 13 with a foot length in centimeters. Measure your longer foot in cm, find your adidas size, and then use each other brand’s own conversion rather than an EU number from somewhere else. Expect Skechers to label the same foot with a smaller UK and EU number than adidas, with Nike in between. Mind the width letters too: B is standard for women, and D is already wide.
