“WOW! Ordered a suit online with Linda. She contacted me by video call to go through the measuring process and once confirmed measurements again, around 4 weeks later a made to measure suit arrived in the UK. Fitted perfectly and I didn't even visit! Fantastic quality and customer service from Linda. Would definitely recommend!”

Waist size: common questions

What is the average waist size for men?
In US civilian adults 20+ (CDC NHANES, 2021–23), the average (mean) waist is about 103 cm, with a standard deviation of 16.2 cm. Source: CDC NHANES — Anthropometric Reference Data for Adults, U.S. (Vital & Health Statistics, Series 3 No. 50, 2021–2023).
How do I know if my waist is small, average, or large?
Enter your measurement above and the tool places it on the bell curve for US civilian adults 20+ (CDC NHANES, 2021–23), returning an exact percentile (the share of people whose waist is smaller than yours). It is a fitting reference, not a judgement — every result is handled the same way.
Does my waist affect how a suit fits?
Yes — and that is the point. Off-the-rack clothing is graded around the middle of the curve, so any distance from average makes mass-produced garments fit worse. A custom suit from Nathan Tailors in Hoi An is drafted to your actual waist, so your proportions become the pattern.
