A radial pattern calculated from true height
A cone cannot be flattened as a triangle. ExactFold calculates the slant lengths and arc angles needed to form the requested circular base and top when the sector is rolled and joined at its seam.
From measurements to a usable template
- Enter the finished dimensions shown beside each field.
- Choose A4 or Letter paper and the closest material thickness.
- Inspect the cut, fold and glue lines in the live preview.
- Download PDF for printing, SVG for craft cutters or DXF for CAD.
Good uses for a cone pattern
- Party hats and paper cones
- Lampshade and sleeve prototypes
- Funnels and model making
- Tapered labels and wraps
Distinguish vertical and slant height
Enter the straight vertical height of the finished cone. The generator calculates the longer slant height automatically. For a wrap around an existing object, test the seam overlap before final cutting.
