FAQs
What is the difference between US and EU trouser sizes?
US and UK trouser sizes state the waist in inches. EU sizes use a different scale, roughly 10 higher — a US 34 waist is typically an EU 44.
Why is the result labelled approximate?
Vanity sizing and different cuts mean the same nominal waist can measure differently between brands. Always check the retailer’s own size chart.
What do short, regular and long mean?
They describe the inseam (leg) length: short is about 30 inches, regular about 32 inches and long about 34 inches, though this varies by brand.
