: If you have a pair of trousers that already fit perfectly, lay them flat and measure them directly. Double the flat waist measurement for your "waist size". 2. Decoding Fit and Style

: Measure around your natural waistline, usually just above the belly button. Keep the tape snug but breathable.

: Measure from the crotch seam down the inner leg to where you want the trousers to end (usually the ankle bone).
