W and L: Decoding Levi's American sizes
You spotted the Levi's 501 perfect on Fastbuy.fr, but faced with the codes W30 L32, confusion sets in. No 38, 40, or 42 as usual. Here's how to master the American sizing system, much more precise than ours once the logic is understood.
1. W and L: Technical definitions
The American system is based on actual measurements in inches, not arbitrary numbers.
W = Waist (Waist circumference): Measurement of the belt circumference. The higher the number, the wider the jeans at the waist.
L = Length (Inseam length): Distance between the crotch and the bottom of the hem.
Conversion: 1 inch = 2.54 cm.
2. The "-10" rule for a quick conversion
To get your American W size, subtract 10 from your French size:
Important: For the 501 rigid canvas 100% cotton, choose a higher W size (e.g., W31 instead of W30) to compensate for the absence of elastane.
3. Size conversion chart (Men)
| US size (W) | Approximate FR size |
|---|---|
| W28 | 36 / XS |
| W30 | 38 / S |
| W32 | 40 / M |
| W34 | 42 / L |
| W36 | 44 / XL |
| W38 | 46 / XXL |
4. Choose the length (L)
The main advantage: customize the length according to your height, no hemming needed.
- L30 : Under 1.75m
- L32 : 1.75m to 1.80m (standard)
- L34 : Over 1.80m
- L36 : Over 1.90m
5. Locate your size on an existing pair of jeans
The Jacron: Leather label on the back of the waistband (right side). The W and L measurements are printed there.
The care label: Inside the jeans (left side). The most reliable information if the Jacron is faded.
Conclusion
You now master the Levi's sizing system. On Fastbuy, our authentic models imported from the USA deserve precise sizing: if in doubt about a 501 Original, always choose the larger size for optimal comfort.
