Wide Width Shoe Size Conversion Guide

Updated: February 2026

Finding properly fitting wide-width shoes becomes more complex when converting between US, UK, and EU sizing systems, as width designations vary across regions. This comprehensive guide explains how to convert wide-width sizes internationally and identifies brands that accommodate wider feet.

Understanding Width Sizing Across Different Systems

💡 Pro Tip: If you previously tried a fix that did not work, make sure to fully reverse it before trying the next approach.

Width sizing systems differ significantly between US, UK, and European standards, making international shopping challenging for those with wide feet. The US uses letter designations (B, D, 2E, 4E), the UK traditionally uses fitting numbers or letters (E, EE, EEE), and most European brands don't specify width at all, instead designing their standard fit for average proportions of their regional market.

US Width Designations Explained

Women's width scale:

AA or 2A = Extra Narrow (approximately 3.3 inches at ball of foot for size 8)
B = Narrow/Standard (approximately 3.5 inches)
D = Wide (approximately 3.9 inches)
2E or EE = Extra Wide (approximately 4.2 inches)
4E or EEEE = Extra-Extra Wide (approximately 4.5 inches)

Men's width scale:

B = Narrow (approximately 3.8 inches at ball of foot for size 10)
D = Standard/Medium (approximately 4.1 inches)
2E or EE = Wide (approximately 4.4 inches)
4E or EEEE = Extra Wide (approximately 4.8 inches)
6E = Extra-Extra Wide (approximately 5.1 inches)

UK Width Sizing System

UK shoe fitting traditionally uses a different system based on letters or fitting numbers. A standard UK fitting is approximately equivalent to a US medium width. UK manufacturers typically offer:

D fitting = Narrow (similar to US B for women, B for men)
E fitting = Standard (similar to US B for women, D for men)
EE or F fitting = Wide (similar to US D for women, 2E for men)
EEE or G fitting = Extra Wide (similar to US 2E for women, 4E for men)

Popular UK brands like Clarks use this system extensively and offer multiple width fittings in many of their shoe lines, making them excellent choices for those with wide feet.

European Approach to Width

Most European brands don't offer explicit width designations. Instead, they design shoes with a standard fit that typically runs narrower than US standard widths. If you wear wide-width shoes in US sizing, you'll often need to size up by half to a full EU size to accommodate width, even though the length may be longer than ideal.

Exceptions with width options:

Birkenstock: Offers Regular and Narrow; their Regular width accommodates most US medium and wide widths
Finn Comfort: German brand offering width options similar to UK fitting system
Waldläufer: Austrian brand known for wide-fitting comfort shoes
Ganter: Another German brand with excellent wide-width options

Men's Wide Width Size Conversion Chart

For men wearing US wide (2E) or extra wide (4E) shoes:

US 8 (2E) → UK 7 (E/EE fitting) or EU 41-42 (standard fit may work, or size up)
US 9 (2E) → UK 8 (E/EE fitting) or EU 42.5-43
US 10 (2E) → UK 9 (E/EE fitting) or EU 44
US 11 (2E) → UK 10 (E/EE fitting) or EU 45
US 12 (2E) → UK 11 (E/EE fitting) or EU 46

When ordering from European brands without width specifications, consider going up half to one full EU size from standard conversion if you wear wide or extra wide in US sizing.

Brands That Accommodate Wide Feet

US Brands with excellent wide-width options: New Balance (extensive width range from 2A to 6E), Brooks (multiple running shoe widths), Propet (specializes in comfort and width options), Drew (orthopedic-friendly wide widths), Orthofeet (therapeutic footwear with wide options).

UK Brands: Clarks (multiple width fittings), Hotter (comfort shoes with wide fittings), Padders (specializes in wider fits), DB Shoes (extra-wide orthopedic options).

How to Measure Foot Width

Measure your foot width at its widest point, typically across the ball of the foot just behind the toes. Stand on a piece of paper, mark the widest points on each side, and measure the distance in inches or centimeters. Compare this measurement to width charts provided by brands, which is more accurate than relying solely on width letter conversions.

Tips for Ordering Wide-Width Shoes Internationally

When shopping from UK retailers, specifically search for brands known to offer width fittings and contact customer service to confirm width equivalents. When ordering from EU retailers without width options, read customer reviews carefully—reviewers often mention if shoes run narrow, wide, or true to size. Consider ordering from retailers with free returns to try multiple sizes if you're unsure about width accommodation.

Material Considerations for Wide Feet

Leather: Natural leather stretches over time and can accommodate slightly wider feet even if initially snug. Full-grain leather offers the most stretch potential.

Synthetic materials: Generally don't stretch significantly, so proper width fit from the start is essential.

Knit and mesh: Athletic shoes with knit uppers (Nike Flyknit, Adidas Primeknit) often accommodate wider feet better than structured shoes, as the material gives and flexes.

Style-Specific Width Considerations

Athletic shoes: Look for brands with explicit wide-width offerings in their running and walking shoes. New Balance, Brooks, and Asics lead in this category.

Dress shoes: European dress shoes typically run narrow. For formal occasions, UK brands like Barker or Loake offer wider fittings in classic styles.

Casual shoes: Brands like Clarks, Ecco, and Skechers generally offer roomier fits that accommodate wider feet without requiring special wide widths.

By understanding these width conversion principles and choosing brands known for accommodating wider feet, you can successfully shop for comfortable, properly fitting shoes from international retailers regardless of your foot width requirements.
