Why Quicksize?
Size systems vary between countries (FR, EU, US, UK, IT, DE, JP, Russia), making online shopping for clothes and shoes a real puzzle. A French size 40 is not the same as an Italian 40, and a Levi's W32 jean does not match a Diesel W32 in actual waist. Quicksize centralises 38+ size guides and 15 interactive calculators to help you avoid buying mistakes.
Our guides cover men, women and children, all clothing types (shirts, jeans, dresses, underwear, shoes, hats, gloves, rings), lingerie and bedding. Each page includes international correspondences, measurement tips, and a common questions FAQ. Our calculators give you your size in seconds from your real measurements.
How to use Quicksize
- Pick your category (clothing, shoes, accessories) from the menu or the tiles above.
- Consult the correspondence table or use the calculator suited to your need.
- Compare with your real measurements (chest, waist, foot length depending on the case).
- Always check the brand's own size chart before buying, since brands have their own grid.
Frequently asked questions
How do I know my exact size without trying on?
Use a soft tape measure and take key measurements: chest, waist, hips, foot length. Note them and compare with the grids in our guides. Each page specifies which measurement to take for the item.
Are Quicksize sizes reliable?
Our tables are based on published international standards (ISO, EN, ASTM). They match 80% of mainstream brands. For premium or luxury purchases, always check the brand's own chart — they can vary by half to a full size.
Why does size vary so much between brands?
It's 'vanity sizing': brands adjust labeling to flatter customers. A size 38 at Zara may fit like a 40 at H&M or a 36 at Prada. The only reliable reflex is to compare cm measurements from each brand, not just the number.
Can I use Quicksize without an account?
Yes, 100% free and no signup. All guides and calculators are freely accessible. The site is available in French, English, Spanish, German and Italian.
