How Does a Shoe Size Chart Work?

To find your shoe size, select the respective column with the size you already know (i.e. if you know that you have an 8 in U.S., pick the “US” column), and look there for the row with your number (in this example: 8). Then move horizontally with your finger to the column which corresponds to the size scale you are looking for (i.e. “UK”). Using this technique you can answer  questions like:

  • What shoe size is 10 inches? (The answer is US shoe size 8 for men and 9 for women)
  • What US shoe size is an EU 42? (The answer is 11 for women and 9.5 for men)
  • What length is a US 41? (The answer is 10.25 inches for men and 10.5 inches for women)
  • What is UK 8 in US sizes? (The answer is 9)

Pro Tipp: If you are looking up your foot length in inches to find your shoe size, please use the closest number in inches that is equal or slightly longer than your foot.

How to Measure Shoe Size?

How to measure your shoe size

Proper sizing: Measure your foot length by placing the foot on a sheet of paper. Mark the circumference (keep the pencil straight!). Then measure the longest distance with a ruler and convert using one of our calculators.

Determining the length of your feet is easy.

  1. The best time to measure is the afternoon or evening when your feet have flattened out. If you measure your feet in the morning, they will be smaller, which would give you the wrong size and then you would buy shoes that were too small.
  2. Put your feet on a piece of paper. Stick the paper to the floor with some tape so that it doesn’t slip.
  3. Draw around your foot with a pen, keeping the pen straight (at 90° to the paper).
  4. Measure the longest distance from the heel to the tip of your big toe.
  5. Enter the measurement into the calculator or compare it with the respective shoe size conversion chart.

Pro tip: If one of your shoes is always too tight, measure both feet and then use the length of the largest foot to calculate the correct size for your footwear. If the two lengths vary a lot, you should consider getting your shoes made specially or using special insoles. For instructions how to measure children´s feet, please see here. If you need to know more about other clothing sizes, please see here: pants sizes, women’s clothing sizes, men’s clothing sizes, or suit sizes.

How to measure Shoe Width?

  1. To determine your foot width, draw the outline of each foot on a piece of paper.
  2. Then, use a measuring tape or a ruler to measure the widest portion of both drawings.
  3. Subtract 1/8 of an inch from the largest number, and the answer is your foot width.

Shoe Width Conversion

In addition to the usual shoe largeness specifications regarding the length of the shoe, some brands also indicate the width of their shoes. This is because shoes that are too narrow or too wide can lead to foot problems. While everybody knows their own shoe size. Hardly anybody knows their shoe width, even though there can be huge variations. Many people require shoes with an extra wide fit.

To determine, what foot width you have, place your foot on a piece of paper on the floor. It’s best to ask someone to draw the outline of your foot with a pen. Repeat the same procedure with your other foot. Then use a measuring tape or a ruler to measure the widest portion of both drawings. Subtract 1/8 of an inch from the largest number. This number is your foot width.

And how does the foot width now translate into shoe spread? You can find different shoe width scales on the market. It is either indicated by the marks M (for medium) or W (for wide) or there are classifications of the shoe width from AAA (smallest width) to EEE (widest width).

Unfortunately, there is no uniform standard here and you have to look at the manufacturer’s website to see how many inches foot width i.e. a BBB corresponds to.

Normally, however, “medium” corresponds to a “D” for men and a “B” for women. Extra wide fitting shoes are usually marked with E to EEEEEE (for ladies) or F to H (for men).

How do I know if a shoe fits?

  1. Feet expand during the day. Therefore, you should buy in the afternoon or evening.
  2. If possible, wear regular socks. Particularly thick or thin specimens can falsify the result.
  3. Sizing system are only there as a guide. Even if you choose boots in your correct number, they may not necessarily fit. Even specimens of the same brand may be different. Always test different sizes of the model of your choice.
  4. Shoes are only comfortable if they fit properly. Take the time to find the right fit.
  5. Never buy footgear that “just about” fits.
  6. Don’t just try on one of the shoes in the pair, but instead, always try on the left and the right shoe.
  7. Take your time having a look through the shop. Also, use the stairs. Make sure that you have 1 to 1.5 centimeters of wiggle room when rolling your foot in the front part of the shoe. This rule does not apply only in the case of high-heeled shoes, in which case a slipping of the foot must be prevented by a firm support.
  8. In any case, test models from different manufacturers. Some brands are made wider or narrower. A correct width, however, is just as important as length when it comes to optimal comfort. If you have narrow feet, you should not choose a smaller shoe size, but go for a brand with a narrower fit instead.
  9. The materials used are also of great importance. Materials such as rubber, leather, artificial leather or fabric stretch in different ways over time. This also affects the fit.
  10. Women in particular often buy small shoes. The reason: False vanity and outdated beauty ideals. Some manufacturers react to this behavior and offer, for example, an actual shoe size 40 as a size 39. However, not all companies do so.


Most international size charts are based on the Brannock system. It is used in America, Canada, Australia, and New Zealand for men and women sizes. The system can be applied to all different types of footwear and was invented by Charles F. Brannock, who developed a foot measuring device in the 1920s.
