How to Measure Your Foot Width for a Correct Sneaker Fit

Why foot width matters

Sneaker width is more than a label. A shoe that is too narrow squeezes the forefoot, causing blisters, numbness, and long-term foot problems. One that is too wide lets your foot slide, which can lead to instability and toe jamming during activity.

When you know your width, you can filter sneaker models that are likely to fit. Many brands offer multiple widths, and you can use that information to narrow your options. For a deeper look at width terminology, see our explanation of shoe widths.

What you need

Gather a piece of paper large enough for your entire foot, a pencil or pen, a ruler or tape measure, and a hard, flat surface like a floor or table. You will also want to wear the socks you plan to wear with your sneakers, because sock thickness affects fit.

• Paper (larger than your foot)
• Pencil or pen
• Ruler or tape measure
• Socks you intend to wear

Step-by-step measurement

Place the paper on a hard floor against a wall. Stand on the paper with your full weight evenly distributed, keeping your foot relaxed. Trace the outline of your foot with the pencil held vertically, touching the paper but not pressing into your skin.

Lift your foot and use the ruler to measure the distance between the two furthest points across the widest part of the traced outline. This is your foot width. Repeat the process for your other foot, because one foot is often wider than the other.

Always use the larger measurement when comparing to a size chart. If you are measuring alone, you can press your foot onto the paper and have someone else trace, or you can use a chalk outline and measure afterward.

How to read width labels

Sneaker widths are commonly labeled with letters. B is typically considered a narrow width for women and a medium width for men in some brands, while D is usually the standard medium width for men and a wide width for women. 2E (or EE) is a wide width for men and extra wide for women.

These conventions vary by brand and country. The key is to use the brand's own size chart rather than your memory. Many brands list a foot width range for each letter, so compare your measured number directly.

If you have very wide feet, look for models specifically offered in wide or extra wide. Our guide to wide sneakers can help you find brands that accommodate wider feet.

Matching your measurement to a brand

Once you have your width number, visit the sneaker brand's official size chart. They often list foot width in inches or centimeters alongside the letter width. For example, a chart might state that D width corresponds to a specific range for a given length.

Do not assume all brands are consistent. Some sneakers run narrow, some run wide, and the same letter can feel different between models. Use the measurement as a starting point, and cross-check with the brand's guidance.

Tips for accurate measurement

Measure your feet at the end of the day, as they naturally swell during standing and walking. This ensures your sneakers will not feel tight later in the day.

Measure while wearing the socks you plan to use. A thick athletic sock adds a few millimeters, which can change your width label.

Place the ruler across the widest point of the outline, which is usually around the ball of the foot, just behind the toes. Keep the ruler straight and measure the full distance from edge to edge.

If you are between widths, round up to the wider option. It is easier to add an insole or wear thicker socks than to stretch a shoe that is too narrow.

What if you fall between widths

If your measurement lands between two widths, choose the wider size. A snug fit can be adjusted with an insole or by lacing differently, but a tight shoe can restrict circulation and cause pain.

Some sneakers are designed with adjustable closures like laces or straps that allow you to fine-tune the fit. For outdoor or casual use, a slightly roomier fit is generally safer.

What to pick for your use

Questions

How often should I measure my foot width?

Measure at least once a year, or whenever you notice sneakers feeling different than before. Feet can change width with age, weight changes, or pregnancy.

Should I measure both feet?

Yes. Most people have one foot wider than the other. Always use the larger measurement when selecting a width.

Can I measure width without a Brannock device?

Absolutely. The paper tracing method works well at home. Just be consistent about pressing your foot flat and measuring the widest point.

What if one foot is wider than the other?

Choose the width that fits your wider foot. Sneakers should never pinch either foot. You can add an insole to the narrower foot if needed.

Are width labels consistent across brands?

No. A D width in one brand may feel like a 2E in another. Always consult the specific brand's size chart before buying.

What does D width mean in men's sneakers?

D is generally the standard or medium width for men in many brands. It corresponds to a certain foot width range, which varies by manufacturer.

What does B width mean in women's sneakers?

B is often the standard width for women in US sizing. It is narrower than D. Some women with wider feet prefer D or even 2E.

How do I know if a sneaker is too narrow?

If your foot feels squeezed across the ball of the foot, or you see bulging on the sides, you likely need a wider width. Discomfort during wear is a clear sign.
