Dodecahedron Net Generator

Unfold a D12 into 12 regular pentagons — printable, with exact dimensions

A dodecahedron net unfolds the 12 regular pentagon faces into a flat pattern. This calculator draws the complete flower-style net with fold lines, dimension labels, volume, and surface area.

The regular dodecahedron has 12 pentagonal faces, 20 vertices, and 30 edges. Its geometry is deeply connected to the golden ratio φ = (1+√5)/2. It's also the shape of a D12 die used in tabletop RPGs.

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

FAQ

What is a dodecahedron net?
A dodecahedron net is a flat arrangement of 12 regular pentagons that folds into a regular dodecahedron. The flower layout shows a central pentagon with 5 around it, plus 6 more extending outward.
How many faces does a dodecahedron have?
A regular dodecahedron has 12 regular pentagon faces, 20 vertices, and 30 edges. It is the dual of the icosahedron.
What is the volume of a dodecahedron?
For edge length a, the volume is V = (15+7√5)/4·a³, approximately 7.6631a³. The golden ratio φ makes the formula elegant.
How does the golden ratio relate to dodecahedrons?
The diagonal of each pentagon face divided by its side equals the golden ratio φ ≈ 1.618. The dodecahedron’s vertices can be placed at coordinates involving φ, and its dual (the icosahedron) shares this deep connection.
