We spent 250 hours researching various approaches to shoe sizing and compared 190+ brand size charts to help you convert with higher accuracy.

Shoe size converter for men and women [US, UK, EU, CM, inches]

NOTE: This conversion is based on the average measurements across brands. Your actual size may vary depending on these factors:

• Shoe brand. Manufacturers are not aligned on how they size their shoes. That’s why you may need size 9 in Adidas and size 10 in Nike. Once you know what brand you’ll be purchasing from, we recommend checking your size using the tool below.
• Your foot measurements. One millimeter is enough to take you from one size to another. Having your exact foot length and width measured before shopping online will increase the chances of getting the accurate size.

Because there is no uniform standard of shoe sizing across all manufacturers, no one can tell you precisely how one size converts to another. But the good news is that there are some common tendencies.

UK to US

The UK sizing scheme does not differentiate men’s and women’s sizes, but the US one does:

EU to US

The intervals between EU sizes are smaller than those in the US scheme. That’s why one US size may be equivalent to two or even three different EU sizes.

Knowing your exact foot length in centimeters/inches will help to determine the more accurate EU size for you:

Because there is no simple formula for converting EU size to US, we recommend using the conversion tool above.

CM / Mondopoint to US

The CM marking is the most no non-sense sizing scheme available today. It’s number simply indicates the foot length in centimeters:

This system is also referred to as Mondopoint. It was developed by the ISO (International Organization for Standardization) in the 1970s as an attempt to simplify conversions between US, UK, and EU sizes.

Because it is commonly used by manufacturers in China, Japan, and South Korea, you might as well see them presented as CN (China) or JP (Japan).

The sizes in this system have intervals of 5 mm: 22, 22.5, 23, 23.5, etc. Use the converter above to see the corresponding US, UK, and EU sizes.

Is your little one beginning to walk and it’s time for their first pair of shoes? Or are you looking for footwear for your preschooler, but nothing seems to fit correctly?

Children’s shoes must fit just right — too snug, and you’ll risk problems. Too big, and your kid could trip.

The problem is that kids’ feet grow at what seems like lightning speed. We’ve put together a helpful kids’ shoe size chart for each age group as well as some tips and tricks.

How to Measure Kids Feet

Measuring your kid’s feet is pretty straightforward, and there are a few ways to do it. When in doubt, you can always get a second measurement from a professional in a children’s shoe shop. If you want to DIY it, here are three easy methods:

1. Tracing

Tracing is the most common way to measure children’s feet at home — it’s easy, and not much equipment is required. Here’s what you need:

• A blank paper.
• A marker.
• Ribbon.
• Ruler.
• One pair of bare feet.

Remember Both Feet

If it’s the first time you’re sizing your child for kids shoes, always measure both feet. It’s not uncommon for one foot to be smaller than the other, so to ensure optimal comfort, measure both.

Here’s what you do:

• Trace the feet: Stand your child on a piece of paper on top of a clipboard or on a hard, non-carpeted floor. Try to get them to stand against a wall with their back straight. Use the marker and trace the outline of the feet — keep the marker at an upright angle for the best results.
• Measure the length: Have your child step away from the paper. Measure the length from the heel to the tallest point on the big toe. Write the results down and mark them as length.
• Measure the width: Grab the ribbon and wrap it around the broadest part of your child’s foot (the ball). Mark where the end of the ribbon touches. Measure the length from the end of the ribbon to the mark, and you’ve got the width.
• Find the size: Once you’ve got your measurements, use your guide to find the appropriate size.

2. Printable Guide

Most shoe brands and manufacturers include a size guide — many even provide you with a handy printable one. These are useful and can help you find the perfect fit. You can have a look at your favorite brand’s website — we love the one from StrideRite.

Here’s what you’ll need:

• A printable guide (this is the one we used).
• Scissors.
• Tape.
• A wall.
• Pencil.
• Credit card.
• Shoelace.
• Your kid.

Here’s the breakdown on what you do:

• Prepare the print: After you’ve printed the guide, use the scissors to cut along the dotted lines — cut the length and width rulers. Then grab the tape and fasten the length ruler to the floor — try to align the curved line with the wall. The idea is that the heel will be against the wall.
• Measure the length: Place your kid’s foot on the length ruler, with the heel up against the wall, aligned with the curved line. Then use a marker to label the first line after the big toe — write the length in the space provided. Remember to use the correct column for the right or left foot.
• Measure the width: While your child is standing up straight, use the width ruler, and slide it under the foot. Wrap it closely around the widest part and mark where the ruler meets the “align here” indicator. Take note of the results.
• Try a shoelace: A shoelace also works to measure the width. Wrap it around the widest part, and then mark where the end touches the lace. Remove it, and measure the distance between the mark and the end that went around the foot.

3. Use a Shoe Size Gauge

Using a size gauge is another simple method of measuring your kid’s shoe size. They’re available to buy online and at some shoe retailers.

Here’s what you need:

• Measuring device.
• Paper.
• Pencil.
• Feet.

And here’s what you do:

• Stand up straight: Ask your child to stand up with their back straight, facing forward.
• Place the foot: Have a look at your measuring device and locate where the heel should be. Then place the right heel in position.
• Note the results: Write down the numbers facing you, and you should have the correct length.
• Measure the width: Some shoe measuring devices have a bar that you slide over your child’s foot to measure the width. Consult the instructions. If not, you can use the ribbon or shoelace techniques mentioned in the two methods above.

How Often to Size Your Kid’s Feet

Tiny tootsies grow fast — between the ages two and six, their feet can grow up to half a size every two to four months. Experts recommend that up until four years, you make a shoe change every two to three months. To ensure the size is correct, look to measure their feet every two months (1).

After their fourth birthday, foot growth does slow down a bit, and they may not need a shoe change that often. Experts recommend every four to six months. However, continue sizing their feet at least every three to four months.

When Your Child Is Between Sizes

Not all feet are similar — sometimes two feet on the same child can grow differently. If your child is between sizes, it’s always recommended to go with the larger foot.

Having a shoe that’s a size too big is better. Using footwear that’s too small could lead to issues such as foot deformities or ingrown toenails (2).

Shoe Buying Tips

1. Shoe Shopping Tips for Babies

Before your baby begins to walk, you don’t need shoes. During this time, baby shoes such as booties, soft-soled, and socks are best. Once your little one starts to take their first steps, it’s time for a supportive shoe (3).

Don't Rush

Hard-soled shoes such as Mary Janes may look adorable, but they aren’t helping your little one walk. Shoes such as these may even delay walking. Being barefoot helps your baby build coordination and strength in their legs and feet.

• Go for breathable and lightweight: For a new walker, comfort is crucial. Look for something made of cloth or soft faux leather.
• Soft soles: When looking at the shoes, try to bend the soles. If they flex easily, they will provide good support for your new walker. If not, leave them on the shelf.
• Shop in the afternoon: Baby feet tend to swell later in the day. So to ensure the shoe fits perfectly, do your shopping in the afternoon.
• Verify the fit: Try to place your pinky finger in between your baby’s heel and the back of the shoe while they stand. If it feels tight, the shoe is probably too small.

2. Shoe Shopping Tips for Toddlers

• Bring socks: Unless you’re shopping for sandals, your tot will likely have to wear socks with shoes. Use the appropriate socks — thick for winter boots and light for summer sneakers. Then the shoe will fit right even when there’s extra padding.
• Forget trends: Don’t give in to the latest trends of clogs, pointy boots, or high heels. These aren’t likely to provide any beneficial support to a toddler who’s still mastering their walk. Instead, go for something supportive.
• Provide options: Some toddlers want to decide what they wear. If so, find a few different, but appropriate, shoes and ask your little one to choose which they like best.
• Opt for Velcro: A hook and loop closure such as Velcro is much easier for a toddler to put on without assistance. This way, your child learns how to put on shoes, and you save time otherwise wasted tying shoelaces.

3. Shoe Shopping Tips for Older Kids

• Let them move: Once your child is wearing both shoes, let them do a strut around the shop. Watch how they walk and see if the shoe provides support, or looks uncomfortable. Then ask your child how they feel — be specific — ask if they feel tight or too loose.
• Thumbs up: While your child is wearing the shoes, try to fit your thumb between the heel and the back of the shoe — you want it snug but not tight, so you avoid blisters. Then use your thumb to press at the front — feel for the big toe and how far forward it sits. There should be a thumb’s width between the toe and the end of the shoe.
• Don’t think too big: If you’re on a budget, It can be tempting to buy a shoe that’s a few sizes too big. This isn’t ideal — at this age, your child is active and needs a supportive shoe that won’t come off unexpectedly.

No More Toe Jam

Finding a correctly fitting shoe size for your child is essential. Footwear that’s too small can lead to long-term side effects, and too large will hinder them from walking or playing correctly. Using a kids’ shoe size chart is a great way to get an idea of which size to go for.

Measure your child’s feet regularly, depending on their age. It’s easy to do at home by tracing, using a printable guide, or purchasing a size gauge.
