Shoe Sizing Tips
- Measure your feet in the afternoon — feet swell during the day
- Stand while measuring for the most accurate reading
- Measure both feet — one is often slightly larger
- Wear the socks you plan to use with the shoes
- Leave about 1 cm (thumb width) between your longest toe and the shoe tip
- Width varies by brand — some offer wide (W) and narrow (N) options
- Children's sizes should be checked every 2–3 months
- When between sizes, go up rather than down
FAQ – Shoe Size Converter
What is a Shoe Size Converter?
A Shoe Size Converter helps you convert shoe sizes between different international sizing systems such as US, UK, EU, and CM (centimeters). It's useful when buying shoes online or traveling abroad.
How does the Shoe Size Converter work?
Select your gender, choose the size system you know, pick your size, and click Convert. The tool instantly displays equivalent sizes in all other systems using standardized conversion tables.
Which size systems are supported?
The converter supports US, UK, EU (European), and CM (foot length in centimeters) for men, women, and children.
Can I use this tool for both men's and women's shoe sizes?
Yes. The converter includes separate tables for men's, women's, and children's shoe sizes for accurate cross-region comparison. Men's and women's sizes differ — a women's US 9 is roughly a men's US 7.5.
Why do shoe sizes differ between countries?
Each country developed its own sizing system historically. The US system is based on barleycorn increments, the EU system uses Paris points (2/3 cm each), and the UK system is similar to US but offset. CM measurements are the most universal since they measure actual foot length.
Does this tool account for brand variations?
This converter uses standard international size charts. However, some brands run larger or smaller, so it's always best to check brand-specific size charts when available. The CM measurement is the most reliable across brands.
How do I measure my foot in centimeters?
Stand on a piece of paper, mark the heel and longest toe, then measure the distance between marks. Do this in the afternoon when feet are slightly swollen. Measure both feet and use the larger measurement.
What is the difference between US and UK shoe sizes?
For men, US sizes are typically 0.5 larger than UK sizes (US 10 = UK 9.5). For women, the difference is about 2 sizes (US 8 = UK 5.5). Children's sizes also differ. Always use a converter rather than guessing.
How often should I measure children's shoe sizes?
Children's feet grow rapidly — check every 2–3 months for toddlers and every 4–6 months for older children. Shoes that are too small can cause foot problems. Always leave about 1 cm of room at the toe.
What should I do if I'm between two sizes?
If you fall between two sizes, it's generally better to go up to the larger size. You can always add an insole for a snugger fit, but a shoe that's too small will be uncomfortable and can cause blisters or foot issues.
