Shoe Width Calculator

Shoe width fitting is one of the most overlooked aspects of footwear. An incorrectly fitted width causes bunions, blisters, numbness and long-term joint problems, even when the length is perfect.

Width measurement method:

1. Trace your foot on paper while standing (weight-bearing)
2. Measure the widest part across the ball of the foot in inches
3. Compare to your shoe length size using the width chart

US shoe width designations (narrowest to widest): 2A (AA) → A → B → C/D → E → 2E (EE) → 3E → 4E → 5E → 6E

For women: B = standard / medium For men: D = standard / medium

Width to measurement guide (women’s, size 8 reference):

Note the letters mean different things on the two charts. A D is the standard men’s width and a wide women’s width, which is why a woman told she needs a D and handed a men’s D ends up in a shoe that is far too big. Both charts shift by about 0.04" per size up or down from their reference.

Worked example: A man with a size 10 length and a 4.5" ball-of-foot width:

• D (medium) is cut for 4.0", so it is half an inch too narrow
• 2E (wide) is cut for 4.4" and covers 4.20 to 4.60", so 4.5" lands here
• 4E (extra wide) is cut for 4.8", roomier than he needs

He is a 2E. If it pinches across the ball, 4E is the next stop, and that is the direction to err in: shoes give a little with wear and feet do not.

Signs your width is wrong:

• Shoe bulges or wrinkles on the side (too wide)
• Toes feel numb or cramped sideways (too narrow)
• Heel slips despite correct length (too wide overall)
• Laces won’t close without pulling (too narrow)

European and UK shoes typically do not use width codes — they use last shapes instead (slim, regular, wide). When ordering internationally, always check the brand’s specific width grading.
