Millimeter-accurate graph paper with instant presets
Set paper size to A4 or Letter, control portrait or landscape orientation, and dial in margins, headers, footnotes, and calibration squares. Tabs switch between Cartesian, polar, log-log, and extension grids without reloading.
Every generation records How it's generated steps, so you can verify line counts, decade spacing, and Δθ values at a glance before printing or distributing.

Workflow tips
Press Enter to regenerate after editing any input, or use Alt + P to jump straight to the print dialog. Include the calibration square whenever printers may rescale.
The Share button copies the full configuration, making it easy to send a permanent grid layout to students or colleagues.
How to make printable graph paper
Use this generator for millimeter-based Cartesian, polar, semilog, log-log, or isometric graph paper that prints to PDF.
Choose the grid type first
Pick the grid that matches the task: Cartesian for coordinates, polar for angles, log or semilog for scale changes, and isometric for sketching shapes.
Tune spacing and strokes
Set minor spacing, major intervals, stroke width, and color so the grid is visible without overpowering pencil or pen marks.
Print and measure
Enable the 50 mm calibration box when exact scale matters. Print at 100% scale and measure the box before using the sheet for graphing or lessons.
Common mistakes to avoid
- Using heavy major lines that hide plotted data.
- Choosing log or semilog paper for values that include zero or negative numbers.
- Printing with shrink-to-fit enabled.
- Forgetting to leave a margin for labels or binder holes.

FAQ
How do I print the generated graph paper?
Download or print the generated page, then choose actual size or 100% scale in the print dialog.
How can I confirm the scale stays accurate?
Enable the 50 mm calibration box and measure it after printing. If it is not 50 mm, disable fit-to-page scaling.
Which grid type should I choose?
Use Cartesian for ordinary coordinate plots, polar for angle-and-radius work, log or semilog for multiplicative scales, and isometric for 3D-style sketches.
How should I set minor and major lines?
Set minor spacing for the smallest divisions you need, then use major lines every few minors to make counting easier without making the page too dark.
Can I make a lighter grid for handwriting or sketches?
Yes. Reduce stroke width or use a lighter color so pencil marks, plotted points, or annotations remain easy to read.
