Gift Ribbon Length Calculator
A cross wrap goes around the box twice — once the short way, once the long way — and the height is counted twice on each pass. A 20 × 15 × 8 cm box takes 102 cm for the two passes, plus 30 cm for the bow, giving 132 cm.

Formula
Ribbon length = 2 × (Box width + Box height) + 2 × (Box depth + Box height) + Spare
The bow allowance is what decides the answer: a hand-tied bow wants 25–35 cm, a large decorative one over 60 cm. Narrow ribbon ties a smaller bow and needs less. Satin frays where it is cut, so leave a centimetre to trim back on the diagonal.
