How much ribbon do I need for a basic bow?

A simple two-loop bow with 15 cm tails on a medium gift needs about 60-80 cm of ribbon. A fuller 6-loop classic bow needs 100-150 cm depending on the diameter.

What ribbon width works best for bows?

For small bows (under 8 cm), use 10-15 mm ribbon. For medium bows (8-15 cm), 25 mm is ideal. For large statement bows, 38-50 mm wired ribbon holds its shape best.

What is the difference between bow styles?

A simple bow has one loop on each side. A classic bow has multiple loops fanned out symmetrically. A pom-pom bow has many loops pulled in all directions for a spherical shape. A florist bow has graduated loops.

Should I use wired or unwired ribbon?

Wired ribbon holds its shape better and is easier to form into structured bows. Unwired ribbon gives a softer, more natural drape and works best for simple bows. Satin ribbon is slippery - grosgrain grips better.

How do I make a bow look fuller?

Use more loops (8-12 instead of 4-6), wider ribbon, and fluff each loop so they face different directions. Wired ribbon is much easier to shape and keeps its fullness.

How We Calculate This

How the Calculation Works

Classic bow: Each loop uses approximately half the circumference of the bow diameter. Multiply by the number of loops, then add tail lengths and centre knot allowance (8 cm).

Pom-pom bow: Similar to classic but with more loops and no tails. Centre tie uses about 10 cm.

Simple bow: Two loops (one each side) equal to the bow diameter, plus two tails and a knot.

Florist bow: Graduated loops where each layer is slightly smaller, creating a layered effect.
