Tetrahedron Net Generator

Unfold a tetrahedron into 4 equilateral triangles — printable, with exact dimensions

A tetrahedron net unfolds the 4 equilateral triangle faces into a flat pattern. This calculator draws the net with fold lines, dimension labels, volume, and surface area for any edge length.

The tetrahedron is the simplest Platonic solid — 4 faces, 4 vertices, 6 edges. Its net is a central triangle with 3 triangles radiating from each edge. Enter an edge length and the net redraws instantly.

Every net is printable — use the share/export button to save, then print and fold into a real tetrahedron.

What is a tetrahedron net?
A tetrahedron net is a flat arrangement of 4 equilateral triangles that folds into a tetrahedron. One triangle serves as the base, and the other 3 fold up to form the sides.
What is the volume of a tetrahedron?
For a regular tetrahedron with edge length a, the volume is V = a³√2/12. This equals approximately 0.1178a³.
What is the surface area of a tetrahedron?
The total surface area is SA = √3·a², since it has 4 equilateral triangles each with area (√3/4)a².
Can I use this as a D4 dice template?
Yes! A regular tetrahedron is the shape of a D4 die used in tabletop RPGs. Print the net, write numbers 1–4 on each face, add glue tabs along fold lines, and fold.
What can it graph?
It can plot explicit, implicit, and parametric functions, add points and geometry, and animate sliders on the same graph.
Can I use voice or a photo?
Yes. You can talk to the tutor, upload a worksheet or handwritten problem, and let the graph update from that input.
Will it explain the steps?
Yes. The AI explains what it is drawing and why, so you see the answer on the graph instead of getting only a final number.
