FAQs
Why is the belt size bigger than my waist?
Belt size is measured from the buckle to the middle hole, so it includes extra length beyond your waist — usually about 2 inches (5 cm).
Why is the result labelled approximate?
Brands measure and label belts differently, so the same nominal size can vary. Always check the retailer’s own chart.
Should I measure over my trousers?
Measure where the belt will sit — usually over the trousers at the waistband — for the most accurate result.
Is my data sent anywhere?
No. Everything runs entirely in your browser and never transmits or saves your entries.
