What this means in practice
Menswear tops and suits are sized by chest measurement: UK 36 is a 36 in (~91 cm) chest. Measure around the fullest part of your chest, level under the arms. Tailored jackets run close to this number; relaxed-fit knitwear often sits a size larger, so check the brand's own chart for outerwear.
How we calculate this
Men's tops and suits convert by chest size in inches (US = UK, EU = US + 10). UK 36 is a 36 in chest (91 cm). These are published size-system conversions, not a per-brand fit guarantee.

Common questions

How do I convert US 36 back to UK?

How clothing size systems relate
The US and UK use numbers (or chest inches for menswear), the EU uses its own numeric scale, and Japan mixes numbers and letters. Most of the world also labels garments S / M / L / XL. Women's and men's systems do not convert the same way, so use the matching chart below. Fit still varies by brand — treat the equivalent size as your starting point.

How to find your size before you buy
- Measure your chest/bust at the fullest point with a soft tape, kept level and snug.
- For menswear, that chest measurement in inches is your US/UK size; add 10 for EU.
- For womenswear, find your usual home size in one column and read across for the rest.
- If you're between two sizes, size up for outerwear and tailored fits.
FAQ
A US women's 8 is a UK 12 and an EU 40 (Japan 11, international M). The same dress measurement simply carries a different number in each country's system.
A US men's 40 (40-inch chest) is the same as a UK 40 and an EU 50 — and roughly a Japanese L. EU menswear is normally your inch chest size plus 10.
No. Women's tops/dresses use one numeric system (UK = US + 4, EU = US + 32) while men's tops/suits use chest inches (US = UK, EU = US + 10). Always use the chart that matches the garment.
Conversions line up the size systems, not every brand's cut. Two labels at the same EU 40 can fit differently. Use the equivalent size as a starting point and check the brand's own chart.
