Fold allowance

The number of millimetres a fold costs: extra material added at every fold to make up for the space the fold needs. It depends on the material.

Material	Board	Allowance
Paper, thin card	≤ 0.5	0.2 – 0.5
Folding carton	0.5 – 1	0.5 – 1
Corrugated E-flute	≈ 1.5	≈ 1.5
Corrugated B-flute	≈ 3	≈ 3
Corrugated C-flute	≈ 4	≈ 4
Double wall (BC)	≈ 6 – 7	≈ 6 – 7

Rule of thumb: about the thickness of the board, as in commercial FEFCO 0427 dielines. For your 6 mm board: about 6 mm. Less makes the box tighter, more makes it looser. Check with one test fold.

Fold allowance is what every fold costs, about the board thickness. The object fits exactly; enter it a little larger for extra room. Scale 100% gives a full-size SVG. The DXF is always full size (1 unit = 1 mm).

Make a box that fits your object exactly. Enter the size of the object you want to pack and the thickness of your board. The tool draws the cutting layout of a folding mailer box with a tuck-in lid, double side walls and locking tabs. No glue or tape needed.
