Printable Protractor
Built by Johnny Alto · free, no sign-up · updated July 26, 2026
Print an accurate protractor when you need to measure or mark an angle and do not have one to hand. Choose a half-circle or full-circle protractor and the size, and it prints to true scale with clear degree markings, ready to cut out and use.
Print at 100% with no fit-to-page so the protractor is accurate. Cut it out, mark the center point, and line the baseline up with one arm of the angle. A downloaded SVG stays perfectly sharp at any size.
A protractor when you need one
A protractor measures and marks angles. The center point sits on the vertex of the angle, the baseline lines up with one arm, and you read where the other arm crosses the scale. This generator prints one to true scale, so as long as you print at 100 percent it is as accurate as a store-bought one. Choose a half-circle 180-degree protractor for most everyday measuring, or a full 360-degree one for laying out complete rotations.
It is genuinely useful for woodworking and DIY layout, sewing and quilting angles, drafting, homework, and any time the real protractor has gone missing.
Print and use it accurately
Accuracy depends entirely on print scale. In the print dialog, set scaling to 100 percent and turn off fit-to-page or shrink-to-fit, then measure the radius against a ruler to confirm. Cut it out, poke or mark the center, and it works like any protractor. For repeated use, download the SVG and print on cardstock so it lasts.

Frequently asked questions
How do I use a printable protractor?
Print at 100 percent, cut it out, put the center point on the angle's vertex, and align the baseline with one arm. Read where the other arm crosses the degree scale.
Is a printed protractor accurate?
Yes, if you print at 100 percent scale with no fit-to-page. Confirm by measuring the radius against a ruler.
Should I use a 180 or 360 degree protractor?
A 180-degree half circle handles most everyday angle measuring. Use the 360-degree full circle for laying out complete rotations or reflex angles.
How do I make it last?
Download the SVG and print it on cardstock, which stays flat and stands up to repeated use better than regular paper.
