How do jeans sizes work? Please note: There are no less than three different sizing systems for jeans in the UK:

  1. The most common method of sizing combines waist width (W) and leg length (L), expressed in inches and in that order, e.g., 32×30. W = waist width = waist circumference; L = leg length = length of inner leg/inseam.
  2. International sizing, also known as Alpha or letter sizing, which usually runs from XS (extra small) to XL (extra large).
  3. For women only: UK jean sizes are often represented by the standard UK size (e.g. 10, 12, 14). US standard sizing or misses sizing, is rendered as one single number, such as size 6.
