Explanation:

• The flat belt length refers to the length of the belt when laid flat (end-to-end measurement without buckle).
• Typically, belt length for jeans is about 2 inches (5 cm) longer than the waist size to allow for comfortable fastening.
• Adjustments can be made for preference: longer lengths if worn lower, shorter if worn at natural waist.

Quick Rule of Thumb:

Jeans Waist Size + 2 inches (approx. 5 cm) = Flat Belt Length
