General Size Chart

Why can’t we rely on weight alone?

Two people with the same height and weight can have very different body shapes. For example, two men who are both 175cm tall and weigh 75kg may have completely different chest and waist measurements — meaning they could need different UK sizes from the same brand. Weight should only be used as a rough starting point. Your final size decision should always be based on your actual chest, waist, and other body measurements.

How to Use Height and Weight More Accurately

• Height determines which length series to choose
  Under 170cm → check Short lengths first
  173–183cm → choose Regular
  Above 183cm → choose Tall or Long lengths
• Weight helps confirm your overall body type
  A heavier person with a narrower waist (inverted triangle) may need a different size than a heavier person with a fuller waist (apple shape). The former can often wear Slim Fit; the latter will be more comfortable in Regular or Relaxed Fit.
