Shoe Size by Foot Length in Inches and Centimeters

Choosing the right shoe size starts with one simple measurement: the length of your foot from heel to toe.

The US shoe size chart below shows common adult men’s and women’s shoe sizes with the approximate matching foot length in inches and centimeters. Use it as a practical guide when buying walking shoes, running shoes, work shoes, or everyday sneakers online.

Shoe sizing can vary by brand, shoe shape, and model, so this chart should be treated as a starting point rather than a guarantee. Shoe size can vary significantly from one style to another, even from the same manufacturer. Note that inch and centimeter measurements refer to heel-to-toe foot length.

How to Measure Your Foot for Shoe Size

You do not need a professional fitting tool to get a useful home measurement. A piece of paper, a pencil, and a ruler or tape measure are enough.

Here is the easiest way to measure your foot:

1. Place a piece of paper on a hard floor against a wall.
2. Stand on the paper with your heel lightly touching the wall.
3. Keep your weight evenly distributed, as your foot may spread slightly when you stand.
4. Mark the tip of your longest toe.
5. Measure from the wall or heel line to the toe mark.
6. Repeat with your other foot.
7. Use the longer measurement when choosing your shoe size.

For the most accurate result, measure your feet later in the day. Feet can swell slightly after walking, standing, exercise, heat, or long periods of activity.

Foot Length Is Not the Same as Shoe Length

The measurement in a shoe size chart refers to the length of your foot, not the full interior length of the shoe.

Shoes need a little extra room in front of the toes. This space helps prevent rubbing, pressure, bruised toenails, and discomfort when your foot moves forward during walking or running.

As a general rule, you should have about a thumb’s width of space between your longest toe and the front of the shoe. This is especially important in walking shoes, running shoes, hiking shoes, and work shoes used for long periods on your feet.

Don’t Forget Shoe Width

Foot length helps determine your shoe size, but foot width is just as important for comfort.

A shoe can be the correct length and still feel uncomfortable if it is too narrow, too wide, too shallow, or too roomy through the heel. If you often feel pressure along the sides of your toes, the ball of your foot, or your pinky toe, the issue may be width rather than length.

Most standard-width shoes are not labeled with a width at all. In US sizing, a standard men’s shoe is usually a D width, while a standard women’s shoe is usually a B width. New Balance, one of the clearest brands for width sizing, lists men’s D as standard and women’s B as standard. It also lists 2E, 4E, and 6E as progressively wider men’s options, and D, 2E, and 4E as progressively wider women’s options.

Common US Shoe Width Sizes

Width labels can vary by brand. Some companies use letters such as B, D, 2E, and 4E, while others use terms such as narrow, medium, wide, extra wide, or XX-wide. The important thing to know is that the same letter does not always mean the same thing in men’s and women’s shoes. For example, D is usually standard in men’s shoes but wide in women’s shoes.

How is shoe width measured?

Shoe width is measured across the widest part of the forefoot, usually around the ball of the foot.

The tricky part is that shoe width depends on shoe length. A width that is considered wide in one shoe size may be standard in a larger shoe size. This is why professional fitting tools, such as a Brannock Device, match width to your measured shoe size.

Use the tables below as general guidance for shoe width converted to a measurement in inches or centimeters.

How to Measure Foot Width

To measure your foot width at home, stand on a piece of paper and trace around your foot. Then measure the widest part of the outline, usually across the ball of the foot.

Measure both feet, because one foot may be wider than the other. Use the wider measurement when choosing shoe width.

For the most accurate result, measure your feet later in the day and wear the type of socks you plan to wear with the shoes. Feet can spread slightly after walking, standing, heat, or exercise.

Signs You May Need a Wider Shoe

You may need a wide or extra-wide shoe if:

• Your toes feel squeezed together
• Your pinky toe rubs against the side of the shoe
• The upper bulges over the sides of your foot
• You feel pressure across the ball of your foot
• You often get blisters on the sides of your toes or forefoot
• Your feet feel numb, hot, or tingly after walking
• You have bunions, hammertoes, swelling, or a naturally wide forefoot
• You regularly size up just to get more room across the front of the shoe

Sizing up can sometimes help, but it is not the same as choosing a wider shoe. A longer shoe may give your toes more room at the front, but it can also cause heel slipping, sliding, and poor support if the real problem is width.

Signs a Shoe May Be Too Wide

A shoe may be too wide if:

• Your heel slips when you walk
• Your foot slides forward inside the shoe
• You need to overtighten the laces to feel secure
• The upper wrinkles or folds across the forefoot
• Your foot feels unstable on turns or uneven ground

Too much room can be almost as uncomfortable as too little room. A good walking shoe should hold your heel securely, feel comfortable through the midfoot, and give your toes enough room to spread naturally.

Should You Size Up or Choose Wide Width?

If your toes hit the front of the shoe, you probably need a longer size.

If the shoe feels tight across the ball of your foot or squeezes your toes from the sides, you probably need a wider width.

If the shoe feels both short and narrow, try the next half size up and a wider width if the brand offers it.

For walking shoes, work shoes, and shoes for standing all day, width matters because your feet may spread during long periods of use. A shoe that feels “just okay” for five minutes may feel too tight after several hours.

Why Your Shoe Size May Vary by Brand

Your measured foot length is only one part of finding the right fit. Shoe size can vary because brands use different lasts, toe box shapes, materials, cushioning systems, and fit profiles. A size 10 in one brand may not feel exactly like a size 10 in another brand. Fit can also change depending on the type of shoe. A walking shoe, dress shoe, trail shoe, running shoe, and work shoe may all fit differently, even in the same listed size.

Pay attention to these fit details:

• Toe box width
• Arch support
• Heel hold
• Overall volume
• Sock thickness
• Insole thickness
• Whether the shoe runs narrow, wide, short, or long

This is why size charts are useful, but reviews and brand-specific sizing notes still matter.

Men’s and Women’s Shoe Size Conversion

In many US shoe brands, men’s sizes are about 1.5 sizes lower than women’s sizes.

For example, a US women’s 9 is often close to a US men’s 7.5 in length. However, the fit may not be identical because men’s shoes are often built wider than women’s shoes.

If you are converting between men’s and women’s sizes, use the size conversion as a starting point, then check the actual foot length and width whenever possible.

When to Size Up

You may want to try a half size larger if:

• Your toes touch the front of the shoe
• You are between sizes
• You plan to wear thick socks
• Your feet swell during the day
• You are buying walking, running, hiking, or work shoes
• You have bunions, hammertoes, or a wider forefoot
• You will be standing for long periods

For walking shoes, comfort over distance matters more than a snug “fashion” fit. A shoe that feels slightly tight in the store may become uncomfortable after an hour of walking.

When Not to Size Up

Sizing up is not always the answer. A shoe may be too large if your heel slips, your foot slides forward, or you feel unstable when walking. Too much movement inside the shoe can cause rubbing, blisters, and poor support. If the length feels right but the shoe feels tight across the forefoot, you may need a wide size instead of a longer size.

Don’t Forget Shoe Width

Foot length helps determine your shoe size, but foot width is just as important for comfort.

A shoe can be the correct length and still feel bad if it is too narrow, too wide, too shallow, or too roomy through the heel. If you often feel pressure along the sides of your toes or the ball of your foot, look for wide sizing or shoes with a roomier toe box.

Common US width labels include narrow, medium, wide, extra wide, and extra-extra wide. Men’s standard width is often D, while women’s standard width is often B.

Final Fit Check

After choosing your size, put both shoes on and walk around indoors.

A good fit should feel secure at the heel, comfortable through the midfoot, and roomy enough in the toe box. Your toes should not feel cramped, but your foot should not slide around inside the shoe.

Check the fit while standing, not just sitting. Your foot changes shape under body weight, which is why a shoe can feel fine while seated but too tight once you start walking.
