Finding the right shoe size is one of the most important steps to ensuring comfort, performance, and foot health. Shoes that don’t fit correctly can cause blisters, foot pain, long-term problems, and may even affect your posture. But with so many different sizing systems worldwide, it’s easy to get confused. That’s where a shoe size chart comes in handy.
In this guide, we’ll explore shoe size systems from around the world, explain how to measure your feet at home, share a detailed shoe size conversion chart, and provide tips for choosing the perfect fit.
Why Shoe Size Matters
Shoes are not just fashion—they are functional tools that protect your feet. Wearing the wrong size can lead to:
Discomfort – Shoes too small pinch and restrict, while oversized shoes slip off.
Blisters & Calluses – Caused by friction from poor fitting.
Foot Problems – Bunions, plantar fasciitis, and arch pain may result from bad sizing.
Posture Issues – Misalignment of your feet affects your back and joints.
A properly fitted shoe gives enough space for movement without being too loose.
Shoe Size Systems Around the World
Shoe sizes vary depending on the country. Here are the major systems:
1. US Sizes
Separate scales for men, women, and kids.
Women’s sizes are typically 1.5 sizes larger than men’s for the same foot length (e.g., Men’s 8 = Women’s 9.5).
2. UK Sizes
Similar to US but about 1 size smaller.
Example: US Men’s 9 = UK Men’s 8.
3. European Sizes (EU)
Based on last length in Paris points (1 Paris point = 2/3 cm).
Same scale for men and women.
4. Mondopoint (Asia & Military)
Measured in millimeters of foot length (e.g., 260 mm = 26.0 Mondopoint).
Very precise and used in countries like Japan, Korea, and China.
Standard Shoe Size Conversion Chart
Here’s a correct international shoe size chart for men and women:
| US Men | US Women | UK | EU | Mondopoint (mm) |
|---|---|---|---|---|

How to Measure Your Shoe Size at Home
If you don’t know your exact size, you can measure your foot with these steps:
Place a sheet of paper on the floor against a wall.
Stand barefoot with your heel against the wall.
Mark the longest point of your foot (usually the big toe).
Measure the distance in centimeters or millimeters.
Compare with the Mondopoint scale or conversion chart.
👉 Always measure both feet—sometimes one foot is slightly larger, and you should size according to the bigger one.
Shoe Sizing Tips for a Perfect Fit
Try shoes later in the day – Feet swell slightly in the afternoon.
Leave a thumb’s width – About ½ inch (1.2 cm) space between toe and shoe end.
Wear socks – Test shoes with the type of socks you’ll normally wear.
Walk around – Make sure shoes don’t slip at the heel or pinch at the toes.
Consider shoe type – Sports shoes may need extra room, while dress shoes fit closer.
Differences Between Men’s and Women’s Shoe Sizes
Women’s shoes are usually narrower than men’s.
A US Men’s size 8 = US Women’s size 9.5 (1.5 size difference).
European sizing uses the same numbers but shoes are shaped differently for men and women.
Kids’ Shoe Size Chart
Children’s shoe sizes can be tricky since their feet grow fast. Here’s a basic chart:
| US Kids | UK Kids | EU | Approx. Age |
|---|---|---|---|
| 5 | 4.5 | 21 | 12–18 months |
| 7 | 6.5 | 23 | 2 years |
| 9 | 8.5 | 26 | 3–4 years |
| 11 | 10.5 | 29 | 5 years |
| 13 | 12.5 | 32 | 6–7 years |
| 2 (Youth) | 1.5 | 34 | 7–8 years |
| 4 (Youth) | 3.5 | 36 | 8–9 years |

Shoe Size for Wide and Narrow Feet
Standard shoes are made in medium width. But many brands offer additional widths:
N / A (Narrow) – Slim fit.
M / D (Medium) – Standard width.
W / E (Wide) – More space in forefoot.
EE / 2E – Extra wide.
If you often feel tightness at the sides of your shoes, you may need wide sizes.
Regional Shoe Size Differences
US vs UK – US sizes are one size larger. (Example: US 9 = UK 8).
US vs EU – EU sizes don’t follow a direct number match. (Example: US Men 10 = EU 43).
Japan/Korea – Sizes are exact foot length in mm, making them very accurate.
Online Shoe Shopping Tips
Shopping online for shoes can be tricky since you can’t try them on. Here are some tips:
Always check the brand’s official size guide.
Read customer reviews for sizing feedback.
Measure your foot and compare with the Mondopoint size.
When in doubt, order two sizes and return the one that doesn’t fit (if return policy allows).
