Asos Size Chart

ASOS size guide at a glance#

ASOS sizes are UK-based. For women’s clothing the US size is four less than the UK size, so UK 8 = US 4 and UK 12 = US 8, and the EU size is the UK size plus 28 (UK 4 = EU 32). Women’s clothing runs UK 4–18 (US 0–14) with a 31–44 in (78–110.5 cm) bust. Men’s tops use the same letter sizes in US and UK, sized by chest from 30 to 48 in (76–121 cm).

ASOS shoes are built on UK shoe sizes. For women add two for the US size (UK 5 = US 7), for men add one (UK 8 = US 9), and the charts below list every US, UK and EU size with foot lengths in inches and cm. ASOS DESIGN, the own-brand label, follows these same charts, but some of its styles run small or note a slimmer cut, so check the size guide on the product page and go by your measurements.

ASOS men’s size charts#

ASOS men’s charts below cover shoes, tops and outerwear, and trousers. Go by your measurements rather than your usual size, since cuts vary by style.

Measure your foot length and find it in the inches or cm column; the chart converts between US, UK and EU sizes.

Letter sizes are the same in US and UK. Go by chest measurement: t-shirts, hoodies and jackets all use this chart.

ASOS men’s trousers are sized by waist in inches. Every waist size comes in three leg lengths: Short 30 in (76 cm), Regular 32 in (81 cm) and Long 34 in (86 cm), so pick waist and length separately.

Frequently asked questions#

Do ASOS shoes run true to size?#

ASOS shoes generally run true to size, with sizing built on UK shoe sizes: women’s run UK 2–9 (US 4–11, EU 35–42) and men’s run UK 3–14 (US 4–15, EU 37–48). Fit can vary by style, so measure your foot length and match it to the inches or cm column for the model you want.

How do I measure my feet for ASOS shoes?#

Place a piece of paper on a flat surface against a wall. Stand on the paper with your heel touching the wall. Mark the tip of your longest toe, then measure the distance from the wall to the mark. Use this measurement to find your size on the ASOS size chart.

Are ASOS sizes the same for men and women?#

No. Men’s and women’s sizes use different scales, and women’s sizes are UK-based numbers while men’s clothing uses letter sizes. Use the chart for the right category.

How do I convert ASOS sizes to other sizing systems?#

Because ASOS is UK-based, women’s clothing converts to US by subtracting four (UK 10 = US 6) and to EU by adding 28 (UK 10 = EU 38). Women’s shoes add two to the UK size for US (UK 6 = US 8 = EU 39) and men’s shoes add one (UK 9 = US 10 = EU 43). The charts above list every row, and the international shoe size conversion chart covers other systems.

What is the ASOS shoe size chart in US, UK and EU?#

ASOS shoe sizes run on the UK scale. Women’s shoes cover UK 2–9, which is US 4–11 and EU 35–42 (foot length 8.3 to 10.6 in / 21.2 to 27.0 cm). Men’s shoes cover UK 3–14, which is US 4–15 and EU 37–48. Add two to the UK size for women’s US and one for men’s US.

What should I do if I’m between sizes?#

ASOS clothing steps in whole UK sizes (one US size apart), so between sizes go by the item: size up for fitted styles or a roomier fit, size down for relaxed cuts. For shoes, size up if you wear thicker socks, since neighbouring rows are about 4 to 8 mm of foot length apart.

Sizing tips#

Keep these in mind when shopping ASOS:

1. Measure first: take your foot or body measurements before reading the charts.
2. Consider sock thickness: for shoes, thicker socks may need a slightly larger size.
3. Check style-specific advice: some ASOS styles fit differently, so read the product description and reviews.
4. Use conversion tools: the women’s international size conversion chart and the shoe size recommender help when converting between regions or brands.

ASOS size conversion questions#

How do ASOS UK sizes convert to US?#

For women’s clothing, subtract four from the UK size: UK 8 = US 4, UK 12 = US 8. Men’s clothing uses the same letter sizes in both. For women’s shoes, add two to the UK size (UK 5 = US 7); for men’s shoes, add one (UK 8 = US 9). Full conversions are in the charts above, and the international shoe size conversion chart covers other systems.

What sizes are ASOS trousers?#

Men’s trousers are sized by waist in inches, from 26 to 40 (66–101 cm), with three leg lengths: Short 30 in (76 cm), Regular 32 in (81 cm) and Long 34 in (86 cm). Women’s trousers use UK sizes 4–26 (US 0–22), which correspond to a 24–47 in (60–119 cm) waist.

Is ASOS DESIGN sizing different?#

No. ASOS DESIGN is ASOS’s in-house label and follows the standard ASOS size charts on this page. Always check the size guide on the product page too, since individual styles can note a looser or slimmer cut.
