Printable Polar Graph Paper
Choose 30-degree or 15-degree primary divisions and the page orientation, then download the polar grid.
Print at Actual Size or 100% so the prepared measurements stay accurate.
What is polar graph paper?
Polar graph paper replaces rectangular X and Y lines with concentric circles and radial spokes. Each point can be placed by its distance from the center and its angle, so circular and directional data is easier to plot accurately.
Use it for polar coordinates, trigonometry, vectors, force directions, rotational measurements, radiation patterns, and circular diagrams. Choose 12 spokes for clear 30-degree sectors or 24 spokes when you need finer 15-degree reference lines.
Which paper size should I choose?
Check the size printed on your paper pack or shown in the printer tray. A4 is standard in most countries, while US Letter is standard in the United States and Canada. Choose a larger size only when your printer or print service supports it.

Which angular division should you choose?
The choices below explain what changes and when each option is useful. Make the actual selection in the download panel at the top of the page.
30° · 12 primary spokes
A 30-degree polar grid provides clear primary sectors for general trigonometry, introductory polar coordinates, classroom plotting, navigation exercises, and circular diagrams.
15° · 24 primary spokes
A 15-degree polar grid provides finer primary sectors for precise vectors, trigonometric functions, physics diagrams, engineering plots, and circular data that needs closer angular readings.
What is polar graph paper used for?
Polar coordinates and trigonometry
Plot radius-angle pairs, periodic functions, common angles, and relationships between direction and distance.
Vectors and physics
Draw force directions, radiation patterns, phase plots, rotational measurements, and navigation exercises.
Circular diagrams
Create compass plots, radial comparisons, circular layouts, and diagrams with a clearly defined center.
Frequently asked questions
Answers about choosing, downloading, customizing, and printing this paper.
Should I choose 12 or 24 spokes?
Choose 12 primary spokes for clear 30-degree sectors. Choose 24 when you need finer 15-degree reference points for vectors or technical plots.
What do the concentric circles represent?
They divide the radius into regular steps. You can assign those steps the scale and units required by your problem.
What are the faint spokes between the labeled angles?
The labeled primary spokes mark the main angular divisions. Fainter secondary spokes divide those sectors into smaller angle steps, making intermediate directions easier to estimate without overpowering the primary labels.
Which file format should I download?
Choose PDF when you want to print at an accurate physical size. Use PNG for notes, worksheets, and image-based documents. Choose SVG when you need an editable vector file for a drawing or design application.
Should I choose portrait or landscape?
Portrait gives you more vertical working room for worksheets, notes, and tall diagrams. Landscape gives you more horizontal room for charts, maps, tables, timelines, and wide drawings. The prepared measurements stay the same in either orientation when you print at 100%.
Why did the paper print at the wrong size?
The print dialog probably scaled the page. Print the PDF at Actual Size or 100%, and turn off Fit to Page, Shrink, and other automatic scaling options. The paper size selected in the print dialog must also match the file you downloaded.
Can I customize this paper?
Yes. Open the polar grid generator when the ready-made sizes or styles on this page do not match your project.
