Poster tube diameter calculator
Rolled diameter of posters or prints and the tube size to use.
How it works
Rolled cross-section area = sheets × length × thickness. Outer diameter = 2 × √(area ÷ π + (core ÷ 2)²). Tube length = sheet width + 20 mm.
Tip
Roll prints face-in around a loose core to avoid creasing.
Questions
What sheet thickness?
Poster paper is about 0.15–0.25 mm; photo paper and canvas are thicker.
Should the tube be tight?
Leave about 10 mm so the roll slides out without damage.
