Size Guide
US, UK and EU conversions for women's apparel and shoes, plus three home measurements — garment length, bust and foot length — that make any size chart usable.
Last updated October 2026
A size chart is only as good as the measurements behind it. The tables below use the common conversion conventions between US, UK and EU sizing; the three measurement steps after them are what turn those numbers into a decision. Measure once, write the numbers down, and carry them into every listing.
Women's apparel: US / UK / EU
| US | UK | EU | Bust (about) |
|---|---|---|---|
| 0 | 4 | 30–32 | 31" |
| 2 | 6 | 32 | 32" |
| 4 | 8 | 34 | 33" |
| 6 | 10 | 36 | 34" |
| 8 | 12 | 38 | 35" |
| 10 | 14 | 40 | 36" |
| 12 | 16 | 42 | 37.5" |
| 14 | 18 | 44 | 39" |
| 16 | 20 | 46 | 40.5" |
UK sizing runs four sizes above US on this scale, and EU sizing varies by two points around the conversion. Bust is the garment's intended body measurement, not the fabric laid flat — a flat measurement must be doubled before you compare it to this column.
Women's shoes: US / UK / EU and foot length
| US | UK | EU | Foot length (cm) |
|---|---|---|---|
| 5 | 3 | 35–36 | 22.0 |
| 5.5 | 3.5 | 36 | 22.5 |
| 6 | 4 | 36–37 | 23.0 |
| 6.5 | 4.5 | 37 | 23.5 |
| 7 | 5 | 37–38 | 23.8 |
| 7.5 | 5.5 | 38 | 24.2 |
| 8 | 6 | 38–39 | 24.6 |
| 8.5 | 6.5 | 39 | 25.0 |
| 9 | 7 | 39–40 | 25.4 |
| 9.5 | 7.5 | 40 | 25.8 |
| 10 | 8 | 40–41 | 26.2 |
Foot length is the only column a brand cannot argue with: lasts differ, conversion labels drift, but a foot measured in millimetres does not. The EU column is a range on purpose — a 38 from one maker fits like a 37 or a 39 from another.
How to measure yourself at home
Step 1: garment length
Lay a similar garment you already own flat on a table, face up. Measure from the top shoulder seam next to the collar down to the hem, following the side seam. Write that number down in centimetres. When a listing publishes a "length" or "back length", compare it to this number directly — and check whether the listing measures flat or on the body, because a flat measurement is roughly half the on-body number.
Step 2: bust
Wrap a soft tape around the fullest part of the bust, keeping it level front to back, and breathe out normally before you read it. The tape should touch, not press. This is your body measurement: match it to the size chart's bust column, then check the garment's stated ease. A tailored blazer with 5 cm of ease and a knit with 15 cm of ease can carry the same size label and fit nothing alike.
Step 3: foot length
Stand on a sheet of paper against a wall, heel touching it. Trace around the foot, then measure from the wall edge to the tip of the longest toe — which is not always the big toe — in millimetres. Do it at the end of the day, when feet are at their largest, and with the sock thickness you expect to wear. Add 5–10 mm of room and match the result to the foot length column above.
One caveat that outranks every table
The conversions here are the common industry consensus, not law. Brands cut to their own blocks and publish their own charts, and the brand's chart outranks any general table, including this one. Always check the size chart on the specific product page before you buy — and if the chart gives a flat garment measurement instead of body measurements, convert it before comparing.
