A EU 91-97cm waist band corresponds to a US L (36-38in) on the standard chart, giving a familiar US letter size to weigh against a European underwear brand's metric-only listing.
European brands sometimes size underwear more closely to actual measured waist than the looser US letter bands do, so a shopper right at the edge between two US letter sizes may find the EU numeric conversion gives a more precise starting point.
Frequently asked questions
Is EU underwear sizing more precise than US letter sizing?
It can be — EU sizing works off a specific waist measurement in centimetres, while US letter sizes (S/M/L) cover a wider band each, so the EU figure is sometimes the more exact reference.
