Printable protractor

If you suddenly realize you need a protractor—whether for homework, a drawing, or a DIY project—it’s easy to think you must rush to the store. But you don’t have to. You can simply download and print a ready‑made template, or even create your own custom protractor right on your computer. Below you’ll find a short guide to both options.

Ready‑to‑print protractor template

To measure and construct angles on paper, a protractor is the classic tool. It’s usually made of plastic, metal, or wood—but a printed version works just as well for many everyday tasks.

On this page you’ll find a printable protractor template that lets you cut out five protractors from a single A4 sheet.

• Format options: PDF and PNG
• Cost: completely free
• Use cases: school geometry, craft projects, sketching, DIY layouts, and more

Just download the file, print it at 100% scale, and carefully cut along the outlines. For extra durability, you can glue the printout onto cardboard or use thicker paper.

How to create your own printable protractor

If you want more control over the look, size, or markings of your protractor, you can design one yourself using common programs like Microsoft Word or Google Docs.

Step‑by‑step in Word or Google Docs

1. Create a new document
   Open a blank document and set the page size (for example, A4 or Letter).
2. Draw the base line
   • Tool: use the line tool.
   • Purpose: this straight line will be the base of your protractor.
3. Insert a semicircle
   • Go to Insert → Shapes and choose a semicircle (or a circle you can cut in half).
   • Position the semicircle so that its diameter lies exactly on the base line and the midpoint of the diameter aligns with the center of the line.
4. Adjust the size
   • Resize the semicircle so it covers the angle range you need—typically from 0° to 180°.
   • Make sure it’s large enough to read the markings comfortably once printed.
5. Add radial lines (degree markings)
   • Using the line tool, draw lines starting from the center point on the base line and extending to the edge of the semicircle.
   • Space these lines evenly to represent degree intervals.
   • For a simple version, you can mark only key angles (e.g., every 10° or 15°).
6. Label the main angles
   • Add text boxes at the edge of the semicircle for key values such as:
     0°, 30°, 60°, 90°, 120°, 150°, 180°.
   • Place the labels so they are easy to read and don’t overlap the lines.
7. Customize the design
   • You can add:
     • A border around the protractor
     • A title, such as “Protractor 0–180°”
     • Additional markings, like smaller ticks for 5° intervals
8. Print your protractor
   • Check that the print settings are at 100% scale (no “fit to page” or shrinking).
   • Print on regular or thicker paper, then cut out the protractor along the outer curve and base line.

Helpful tips for better accuracy

• Paper size:
  Make sure your design matches the paper size you’ll use (A4, Letter, etc.) so the scale remains accurate.
• Paper thickness:
  Use thicker paper or cardstock if you want a sturdier protractor that won’t bend easily.
• Even spacing:
  When drawing radial lines, take your time to keep them evenly spaced so the degree intervals are as accurate as possible.
• Use a straight edge:
  For measuring angles later, align a clear plastic ruler or straight edge with the base line and the side of the angle for more precise readings.
