Printable protractor

Measurement settings

The diameter changes the spacing between degree marks, not the angles themselves.

What can I customize?

Angles: 180° / 360°; Diameter: 80–250 mm.

How do I use this template?

Align the centre with the vertex and the zero line with one ray.

What should I check?

Uneven horizontal and vertical stretching distorts angles; compare both calibration directions.

Choose 180° for ordinary geometry exercises and 360° for full rotations.

Cut the optional inner windows carefully while preserving the centre bridges.
