Side-by-side comparison, when-to-use-each guide, and instant conversion. Reviewed for 2026.
Quick answer: UK uses letters E to H for widths (E=narrow, F=standard, G=wide, H=extra wide for men; D=narrow, E=standard, EE/F=wide for women). US uses AA-EEE system. EU shoes rarely have widths labelled. Most high-street shoes come in standard (F/E) only — wide fittings need specialist retailers.

Frequently asked
?
Why do most high-street shops not offer width fittings?
Stock complexity — offering multiple widths per style multiplies inventory requirements. High-street retailers focus on the 80% of feet that fit standard width. The growth of online retail has made wide-fitting specialists more accessible.
?
How do I know if I need a wide fitting?
Signs: your foot bulges over the sides of shoes, laces pull tight across the top, or the heel fits but the front is cramped. A shoe fitting in a Clarks or specialist retailer can measure both length and width professionally.
