How to Use This Chart
The most accurate way to find your shoe size is to measure your foot length in millimeters from heel to longest toe, then look up that length in the Foot Length column. The row will show your exact size in every system. Add 5 to 10 mm for comfort if you prefer a slightly loose fit, especially for running shoes, closed toe shoes, or boots. Always re-measure if you have not done so in a few years, since adult feet continue to change over time, particularly during pregnancy or significant weight change.
Width Matters Too
Shoe length is only part of the equation. Shoes are also categorized by width using letter codes: A (narrow women), B (standard women), D (standard men / wide women), 2E or EE (wide men), 4E (extra wide). Brands like New Balance and ASICS offer explicit width options in most styles. Most other brands make a single medium width (D for men, B for women). If your feet are wider or narrower you may need to size up or down to compensate.
Common International Shoe Shopping Mistakes
The most common mistakes are: (1) assuming your US size translates directly to the number on an international shoe box (it never does); (2) forgetting that men and women sizes are offset in US sizing but unified in Mondopoint; (3) not accounting for brand specific fit (Nike runs small, Converse runs large); (4) measuring once instead of both feet; (5) not adding comfort room. Avoid all five by using a foot length based approach to international shoe shopping.
Frequently Asked Questions
How do I measure my foot size at home?
Stand on a piece of paper against a wall with your heel touching the wall. Mark the tip of your longest toe. Measure from the wall edge to the mark in millimeters. See our full guide at /size/how-to-measure-foot-size.
What is the difference between US men and women shoe sizes?
US men and women shoe sizes are offset by 1.5. A US women 9 is approximately a US men 7.5. Both correspond to the same foot length (approximately 254 mm).
How do UK shoe sizes compare to US?
UK shoe sizes run about 1 size smaller than US men and 2 sizes smaller than US women. A UK 8 equals a US men 9 and US women 10.
What is Mondopoint sizing?
Mondopoint is the international shoe size standard based on foot length in millimeters. It is used in Japan, Korea, China, and increasingly for athletic footwear worldwide. A Mondopoint 265 means your foot is 265 mm long.
Are shoe sizes different for men and women?
In the US, UK, and Australia, yes. Men and women shoe sizes use different numbering. In Japan, Korea, and increasingly Europe, unisex sizing based on foot length in mm is used.
How do I know if a shoe will fit without trying it on?
Measure your foot length in millimeters, add 5 to 10 mm for comfort, and match to the brand size chart. Then check brand specific fit notes (does the brand run small, large, narrow, wide) and read customer reviews for the specific style.
Why do different brands fit differently?
Even at the same size, shoes vary in last shape (the mold around which they are built), toe box width, instep height, and material stretch. Nike running shoes often fit narrower than Nike casual shoes. Always check brand and style specific fit guidance.
What is shoe width and how do I measure it?
Shoe width is the circumference of the ball of your foot. Standard widths are A (narrow women), B (standard women), D (standard men / wide women), 2E or EE (wide men), 4E (extra wide). Measure by wrapping a tape measure around the ball of your foot.
