Mailing tube size calculator
Find the right mailing tube for rolled posters, prints and plans.
How it works
Measure the edge of the print that will run along the tube; for a 24 × 36 poster rolled on the short side, that's 24 inches. Rolled diameter depends on paper weight and how tightly you roll: a single poster rolls to about 1.5 to 2 inches, a stack of prints more.
Leave a little extra diameter so the roll slides in without creasing, and room at each end for the plugs or caps. Many plastic end caps sit about half an inch inside the tube.
Tubes are cheap and strong, but carriers price them as rectangular boxes. A long, thin tube can have a higher dimensional weight than you'd expect, and some carriers add a surcharge for cylindrical packages.
Results are estimates based on typical industry values. Confirm final specifications with your supplier or carrier.
Frequently asked questions
What size tube do I need for a 24 × 36 poster?
Roll it along the 24 inch side and use a tube about 26 inches long with a 2 to 3 inch inside diameter.
Do carriers charge extra for tubes?
Some do. Cylinders don't stack well, and carriers may add a handling surcharge. Check your carrier's rules.
