Graph Paper Generator
Pick a paper size, grid type and spacing, then print or save as PDF. Square, dot, isometric and engineering grids drawn at exact millimetre scale — nothing to download.
Grid settings
Every change redraws the sheet at true paper scale.
#7C3AED or #333.In the print dialog set Scale to 100 / Actual size and Margins to None — “Fit to page” silently rescales the grid.
Live preview
The preview is a scaled thumbnail at true aspect ratio; the printout is full size. Grid coordinates snap to 0.1 mm and use crisp edges so hairlines stay sharp.
How it works
Three steps, about thirty seconds.
Letter, Legal, A4 or A3. The sheet is re-derived in millimetres and the grid is re-clipped to the new printable area.
Square for normal work, dot grid for sketching, isometric for 3D drawing, engineering for a heavy rule every fifth line.
Set Scale to 100 / Actual size and Margins to None, then print — or choose “Save as PDF” in the same dialog.
FAQ
Is the printout really to scale?
Yes. The sheet is an SVG measured in millimetres and the print stylesheet pins @page to the selected paper with zero margin, so 5 mm spacing measures 5 mm on paper (±0.3 mm over a 100 mm span) as long as you keep Scale at 100 / Actual size.
How do I get 5 mm or ¼ inch squares?
Choose Square, then type 5 with the unit set to mm — or switch the unit to in and type 0.25 (6.35 mm). Both are one click apart in the spacing row.
Why is the last row or column clipped?
If the spacing does not divide the printable area evenly, the leftover sliver at the right and bottom edges is dropped rather than drawn as a stretched or partial cell. The spec readout tells you the exact remainder.
Which line weight should I use?
Hairline for very fine guide grids, Thin (0.25 pt) for everyday graph paper, Medium (0.50 pt) for grids you will photocopy or pencil over heavily.
Does anything get uploaded?
No. The whole grid is generated in your browser; there is no server call and no account.
Can I change the line colour?
Yes — light gray, blue, black, or any 3- or 6-digit hex value. Pale gray keeps hand-drawn work readable; blue is easier to see on screen.
