Graph paper generator
Choose a spacing, print. The grid is drawn in physical units, so a quarter-inch grid is a quarter inch on paper — as long as you print at 100% scale.
Ready-made grids
One click sets the grid up and generates it. Print straight away.
Which spacing for which job
- 1/4 inch (6.35 mm) — the workhorse. One digit per square makes column addition, subtraction and long multiplication line up automatically. Also the standard for area models of multiplication.
- 1/2 inch (12.7 mm) — for younger children whose handwriting does not yet fit a quarter-inch square, and for the first bar graphs where the squares are the unit.
- 1 cm — the metric equivalent of quarter-inch. Use it when the class works in centimetres, so the grid doubles as a ruler.
- 5 mm — fine enough for plotting graphs and scale drawings, still big enough to write in.
- 2 mm — for scale drawings and design work, not for writing.

Print at 100%, never “fit to page”
This is the only page on Kujji where a print setting can make the output wrong rather than just ugly. If your print dialog is set to scale to fit, a quarter-inch grid might come out at 5.5 mm, and every piece of measurement work done on it will be slightly off. Check the scale setting before printing, and turn off browser headers and footers.
A quick way to verify: print one sheet, then measure five squares with a ruler. Five quarter-inch squares should measure 31.75 mm (1¼ inches). If it does not, the print scale is wrong.
Uses beyond arithmetic
- Area and perimeter — count squares directly, no formula needed at first.
- Coordinates and transformations — quarter-inch with axes, then move to a labelled coordinate plane.
- Bar charts and pictograms — one square per unit.
- Scale drawings — one square equals a fixed distance in the real world.
- Handwriting and letter sizing — half-inch squares give a clear height to aim for.
Questions
Which spacing should I use for long multiplication?
Quarter-inch (6.35 mm) is the usual choice in US classrooms, because each digit sits in one square and the columns line up without any effort from the child. In metric countries, 5 mm or 1 cm works the same way.
Why do my grid lines not line up with the paper edge?
They are not supposed to. The grid starts from the top-left of the printable area, and a partial square at the right or bottom edge is normal. If you need the grid centred, use the axes option, which draws centre lines you can align to.
What is “major every 5”?
It draws a heavier line every fifth square, creating blocks of 5 × 5. That is the standard for reading graphs quickly — counting in fives is far easier than counting individual squares.
Can I print landscape?
Yes. Orientation is a setting. On A4 landscape you get a wider grid, which suits area models and bar work better than portrait.
Is the grid actually the size it says?
Yes, provided you print at 100% scale. The grid is generated in millimetres and inches, not pixels, so it is independent of your screen and of browser zoom. If you print at “fit to page”, it will not be accurate.
