Shoe size converter
Convert men's, women's, and kids' shoe sizes between US, UK, EU (Paris point), and foot length in centimeters. EU 42 often maps to US men's ~8.5 — but brands vary. When possible, buy by measured foot length (mondopoint) for accuracy.

Approximate conversion between common shoe size systems.
How to convert shoe sizes
1. Measure foot length from heel to longest toe in cm (stand, end of day).
2. Select gender/age category if required — scales differ for men, women, kids.
3. Enter known size in one system or foot length directly.
4. Compare converted size and prefer retailer size charts for the specific brand.
Shoe size examples
EU to US men
EU 43 ≈ US men's 9.5–10 depending on brand. Foot length 27 cm often aligns with EU 42–43.
UK vs US
US men's sizes run about one size larger than UK for the same length (US 10 ≈ UK 9).
Women vs men
US women's 9 ≈ US men's 7.5 for similar length — unisex listings may use men's scale.
When to convert shoe sizes
• When you order from international sites listing EU or UK sizes only.
• When you translate sizing after measuring feet in cm at home.
• When you gift shoes and know the recipient's size in one system only.
When to choose something else
• When the brand publishes its own chart — brand charts beat generic conversion.
• When you need width (D, EE) — length conversion ignores width fit.
• When you convert clothing sizes — different tables entirely.
Mondopoint and ISO standards
Mondopoint labels shoes by foot length in mm (260 = 26.0 cm). Military and some athletic brands use it. Converting US→EU without measuring causes returns — measure first, then map through length.
Brand-specific quirks
Running shoes may recommend +0.5 size for toe box; dress shoes fit snug. Wide feet need width codes, not just converted length. Read return policies on cross-border orders.
Frequently asked questions
Why do two EU 42 shoes fit differently?
Manufacturers use different lasts and rounding. Foot length in cm is the most objective input.
How do I measure foot length?
Stand on paper, mark heel and longest toe, measure cm. Use the larger foot; allow ~10 mm toe room for running shoes.
EU size formula?
Roughly EU ≈ 1.5 × footLengthCm + 2 (Paris point approximation) — charts vary.
Kids sizes?
Kids US scales reset and differ from adult — select kids mode, not adult minus offset.
Half sizes?
US/UK use half steps; some EU brands skip half sizes. Converter interpolates approximately.
