W32, L34... How to convert your Levi's Jean size to French size? (The Easy Guide)
Share
You found the Levi's of your dreams on Fastbuy, but you're hesitating in front of "W30 L32"? Don't panic. The American system is actually more precise than the French one. Here's how to find your perfect size in less than 2 minutes, without even trying on the jeans.
1. Decoding the code: What do W and L mean?
US sizes are in inches (1 inch = 2.54 cm)
W (Waist) = Waist circumference. It is the width of the jeans at the waistband.
L (Length) = Leg length. It is the length from the crotch to the bottom of the hem.
2. The Golden Rule of Conversion
A US size W30 roughly corresponds to a French 40. Formula: US Size + 10 = FR Size.

For a perfect fit, it’s better to measure one of your own jeans laid flat rather than relying solely on the conversion.
3. How to choose the right Length (L)?
Many people ignore the length and end up with jeans that are too short or bunch up too much.
L30 : For people around 1.70m.
L32 : The standard (1.75m - 1.80m).
L34 : For tall people (over 1.85m).
L36 : For very tall people.
4. The material trap: 100% Cotton vs Stretch
100% Cotton (Ex: Some 501®): It is rigid denim. It doesn’t forgive. If you are between two sizes, take the larger size.
The Stretch (Ex: 510™, 511™, 512™): These models contain elastane. They stretch a bit. Take your exact size, or even half a size smaller if you like it very tight.
5. The special case of the 501® Shrink-to-Fit™ (LVC)
Be careful this model shrinks when washed, the goal is for it to adapt to your body shape!
Tip: You should buy it larger (often +1 size in width, +2 sizes in length) if you plan to machine wash it.
Conclusion
Now that you know your US size, all that's left is to find your fit.
