Shoe Size Chart: Match Foot Length in Inches & CM to US, UK, EU Sizes

A shoe size chart lists foot length in inches or cm next to US, UK, and EU sizes. For example, 10 1/4 inches (26 cm) equals men’s US 8, women’s US 9.5, UK 7.5, and EU 41.5. To convert cm to inches, divide by 2.54.

This guide gives you one US shoe size chart, simple steps to measure shoe size at home, a shoe width size chart, and fit tips that prevent wrong orders.

US Shoe Size Chart

Men’s and women’s shoe sizes don’t use the same number scale — a US men’s 9 is not the same length as a US women’s 9. For exact numbers, see our Men’s Shoe Size Chart and Women’s Shoe Size Chart. Both include the matching UK, EU, and cm sizes.

How to Convert Inches to Shoe Size

Take your longer foot measurement in inches. Find the nearest value on the shoe size conversion chart. Then read across.

Example: A foot of 10 1/4 inches matches a men’s 8, a women’s 9.5, and EU 41.5.

Only have cm? Divide by 2.54. A 26 cm foot is about 10.2 inches.

Shoe Width Size Chart

Shoe width is the girth around the ball of your foot. It uses letters, from narrow to extra wide.

Shoe width is the girth around the ball of your foot. It uses letters, from narrow to extra wide.

• Medium is usually B for women and D for men
• Letters vary by brand, and some stores group them differently
• A wide shoe adds about ¼ inch of toe-box room; extra wide adds about ½ inch

Signs you need a wider shoe:

• Your foot spills over the sole edge
• The sides of the shoe bulge
• The shoe fits in length but pinches across the ball

How To Convert Foot Size To Shoe Size

Foot Length to Shoe Size Formula

This formula gives a fast estimate from your length in inches:

• Men’s US size = (3 × inches) − 22
• Women’s US size = (3 × inches) − 21

Example: A 10.25-inch foot gives (3 × 10.25) − 22 = 8.75. Round up to a men’s 9, which matches the chart above.

Treat the result as a starting point. Brand lasts and shoe styles can shift it by a half size.

Shoe Fit Tips Before You Buy

• The heel should sit snug with no slipping.
• The midfoot should feel secure but not tight.
• Leave wiggle room in the toe box, about a thumb’s width.
• Fit the larger foot. New Balance says feet can differ by up to a full size.
• Re-measure every year. Feet often grow with age, and many women go up half a size or more after pregnancy.
• Watch for toe cramping, numbness, calluses, and blisters. These point to a shoe that is too small.

How To Measure Shoe Size At Home

• Tape a sheet of paper to a hard, flat floor
• Stand on it with your weight evenly balanced
• Mark your heel and your longest toe, keeping the pen straight up and down
• Measure the gap between the marks in inches or cm
• Repeat with the other foot, and use the longer number

Best Time To Measure

• Measure in the late afternoon or evening — feet swell during the day and reach their largest size then
• A morning measurement can leave you with shoes that feel tight by dinner
• Always wear the socks you plan to use with the shoes while measuring
