International Shoe Sizes Explained: UK, US, EU & Mondopoint

Let’s make international shoe size conversion simple. UK, US, EU and Mondopoint systems all measure differently, and brands add their own quirks. This quick, no-nonsense guide helps podiatrists, physiotherapists, shoe fitters and everyday shoppers find the right size, first time.

Main Sizing Systems (Plain-English)

• UK sizes: Increase in one-third-inch steps. Adult ranges commonly Men 3–13, Women 2–9.
• US sizes: Rule of thumb: Men: UK + 1; Women: UK + 2.
• EU sizes: Paris points (1 point ≈ 6.67 mm). Approx. Men: UK + 34; Women: UK + 33.
• Mondopoint: Foot length (and sometimes width) in millimetres (e.g., 270 mm = 270). Common in safety, military and ski boots.

Fast Conversion (At-a-Glance Tables)

Conversions are approximate. Last shape, toe allowance and brand policy vary. If in doubt, measure and try on.

How to Measure Your Feet (Clinic & Home)

1. Measure length in mm: Stand on paper, heel to wall. Mark the longest toe; measure heel-to-toe. Repeat both feet and use the larger.
2. Measure width: Wrap a tape around the widest forefoot. Note brands with width fittings (e.g., D/E/EE or EU width codes).
3. Match to a chart: Start with Mondopoint or the brand’s own guide; then cross-reference to UK/US/EU.
4. Allow for the job: Runners may need up to a thumb’s width; dress shoes usually less. Orthotics reduce internal volume - plan accordingly.

Professional Tips (for Podiatrists, Physios, Orthotists & Fitters)

• Think function, not just length: Forefoot width, heel grip, instep height and orthotic volume all matter.
• Account for socks & swelling: Diabetics, oedema and long-shift wearers may need extra room.
• Beware brand drift: Some labels “vanity size” or cut narrow/short. Check internal length if published.
• Devices change fit: AFOs, heel lifts and cushioned insoles eat space—consider half-size up or wider lasts.

Common Pitfalls (With Quick Fixes)

• All EU 42s are equal. They’re not. Last shape and toe spring change feel. Measure internal length or try on.
• Ignoring width. Right length, wrong squeeze. Choose width fittings or a broader last.
• Wrong allowance for activity. More room for mileage, less for formal wear.

Quick Reference: Simple Rules of Thumb

• Men: US = UK + 1; EU = UK + 34.
• Women: US = UK + 2 - EU = UK + 33.
• Mondopoint (mm): EU size × 6.67 (approx)
