How socks and tights sizing works
Sock size is usually based on shoe size or foot length. Tights size needs an extra body-length check, so height can change the recommendation even when the shoe size stays the same.
This converter estimates sock size and tights size from US, EU, UK, or centimeter inputs. It is meant for everyday shopping, not medical compression hosiery or specialty performance sizing.
What to enter
Shoe size
Use the shoe size system shown on the product page: US, EU, UK, or foot length in centimeters.
Height
Add height when buying tights, leggings, or full-length hosiery. It helps avoid sagging or overstretching.
Gender/style
Men's, women's, children's, and unisex charts can use different shoe-size offsets and size ranges.
Common fit checks
| Item | Main sizing signal | Watch for |
|---|---|---|
| Socks | Shoe size or foot length | Bunching, heel slipping, tight cuff marks |
| Tights | Height plus shoe size | Too-short rise, sagging, overstretched fabric |
| Children's socks | Current shoe size | Growth room without loose heel fabric |
| Compression hosiery | Brand medical chart | Do not rely on a generic converter |
Shopping tip
If socks are between sizes, choose based on shoe fit and fabric stretch. For tights, height usually matters more than shoe size once the foot fits correctly.
Frequently Asked Questions
Are sock sizes the same as shoe sizes?
No. Sock sizes usually cover a range of shoe sizes, such as S, M, L, or XL.
Why does height matter for tights?
Tights need to reach from foot to waist. Height affects rise and leg length, so it can change the recommended size.
Can I use this for compression socks?
No. Compression socks and medical hosiery require brand-specific circumference and compression charts.
What if socks bunch inside my shoes?
The sock may be too large or too thick for the shoe. Try a smaller size or a thinner fabric.
