Free Printable Cylinder Net Generator

Make a paper cylinder or an open tube from your chosen diameter and height. Add one or two circular ends, with folding tabs along the side panel.

More options

Print at Actual size / 100%. Check that the scale line measures 50 mm (1.97 in).

Print preview

The preview is scaled to fit your screen. Downloads keep the actual dimensions, with no dimension labels over the template.

How a cylinder net is calculated

The rectangular side panel is π × diameter wide and the same height as the finished cylinder. Each circular end has the diameter you enter. Glue tabs are added outside these dimensions.

Cut and assemble your cylinder

Cut the solid outlines and fold the dashed lines. Roll the rectangle into a tube and glue its side seam. For a closed cylinder, fold the small end tabs inward and attach the separate circular ends.

Frequently asked questions

Can I make an open paper tube?

Yes. Choose Open tube for no circular ends, one circular end for a cup-like model, or two circular ends for a closed cylinder.

Are the dimensions inside or outside measurements?

They describe the geometric cylinder at the center of the printed line. Paper thickness and the glued seam can affect the assembled dimensions, so make a test piece if fit matters.

Dimensions are measured at line centers. Curves are approximated with fine line segments. Solid lines are cutting lines and dashed lines are folds, except when you choose a dashed spiral style. Small glue tabs may be limited automatically. Allow for paper thickness, glue and printer accuracy when assembling.
