How to Measure Your Foot at Home

  1. Place a blank sheet of paper on a hard flat floor. Stand on it barefoot with your full body weight distributed evenly.
  2. Hold a pencil vertically, not angled inward, and trace carefully around the entire outline of your foot.
  3. Use a ruler to measure the longest distance from the back of your heel to the tip of your longest toe. Record this in centimetres.
  4. Measure the widest point across the ball of your foot. This gives you your width measurement.
  5. Measure both feet and use the measurement from the larger foot. The majority of people have one foot that is slightly bigger than the other.
Tip — Measure your feet in the afternoon or evening. Feet naturally swell during the day and can be up to half a size larger by late afternoon compared to the morning.

Shoe Width Chart

Shoe width codes indicate how much room there is across the ball of the foot and vary between brands and regions.

Shoe Width Codes Explained
Width Code Width Name Who It Is Suited For
N or AANarrowSuited for slim feet with a narrow ball width.
B (women) / D (men)Medium / StandardThe most common width found in most off-the-shelf shoes.
W or EWideSuited for feet with extra width across the ball or high instep.
XW or EEExtra WideSuited for very wide feet or those with conditions such as bunions or swelling.
EEEE or 4EUltra WideSpecialist medical or comfort footwear width.

Running Shoe Sizing Guide

Running shoes are sized differently from casual footwear because the foot swells during exercise and needs extra space at the toe box.

  • Go up half a size from your regular shoe size when buying running shoes. Most podiatrists and running specialists recommend this to accommodate foot swelling during a run.
  • Leave a thumbnail's width (approximately 10 to 12 mm) between your longest toe and the end of the shoe. Your longest toe may not be your big toe.
  • Try on running shoes in the afternoon or after a short walk when your feet are at their largest.
  • If you are between sizes always go with the larger size. A shoe that is slightly too long is more comfortable than one that is too short.
  • When in doubt visit a specialist running store where staff can assess your gait and foot shape and recommend the correct fit.

Frequently Asked Questions

What is a US size 8 in EU shoe size?
US Women's 8 is EU 39. US Men's 8 is EU 41.
What is EU shoe size 41 in US?
EU 41 is approximately US Men's 8 or US Women's 10. The exact equivalent depends on the brand and whether you are shopping for men's or women's footwear.
Do shoe sizes run the same across all brands?
No. Converse typically runs half a size large and Birkenstock uses European sizing only. Always check brand-specific fit notes or reviews before purchasing, particularly when buying online.
How do kids' shoe sizes compare to adult sizes?
US big kid size 7 is equivalent to US Women's 9. Big kid size 1 is equivalent to US Women's 3. Kids' sizes do not directly translate to men's sizes in the same way.
Should I size up when buying running shoes?
Yes — go up half a size from your regular shoe size to accommodate foot swelling during exercise and to ensure adequate toe box space. Your longest toe should have a thumbnail's width of clearance at the front.
What does 2E width mean in shoes?
2E is a wide width classification, one step wider than standard D width for men. It provides extra room across the ball of the foot and is recommended for wide feet or those with bunions.
How do I know if shoes fit correctly?
There should be a thumbnail's width of space between your longest toe and the end of the shoe. The widest part of the shoe should align with the widest part of your foot without squeezing.
What does D width mean in shoes?
D is medium or standard width for men and represents the most common width sold in off-the-shelf footwear. For women D is a wide width — the standard female width is B.
