Graph Paper (Printable)
Print true-to-size graph paper in four densities — 4, 5, 8, or 10 squares per inch — on a full US Letter page, with every fifth line darker.
Real graph paper generated as an exact grid, not a stretched image: pick the density and the page fills with squares of that true size, with a slightly darker line every fifth square like the pads in a stationery store. For math class, engineering sketches, floor plans, and charting by hand.
Full US Letter page (40 × 52 squares at this density). Every fifth line is darker, like store-bought graph paper. In the print dialog, set margins to None and scale to 100% for true-to-size squares.
How to use this calculator
- Choose a density: 4, 5, 8, or 10 squares per inch.
- Click Print Graph Paper.
- In the print dialog set margins to None and scale to 100% for true-size squares.
The formula
Spacing in screen units = 96 / squares-per-inch, and the line count is the page size divided by that spacing. At 5 per inch: 768 / 19.2 = 40 columns across the printable width.
Worked example
At 5 squares per inch the page holds a 40 x 52 grid — 2,080 full squares — with darker anchor lines at every fifth position, just like a store-bought pad.
Frequently Asked Questions
How do I make the squares print at the exact size?
In the print dialog, set Scale to 100% (or Actual size) and margins to None. The grid is built in true inches at 96 dpi: at 5 squares per inch each square is exactly 1/5 inch when the printer does not rescale it.
Which density should I choose?
4 per inch is easiest for young students and big diagrams. 5 per inch is the standard school and lab density. 8 and 10 per inch suit detailed plotting, cross-stitch and pixel-art patterns, and small handwriting.
How big is the printed grid?
The grid covers an 8 x 10.5 inch area of the Letter page. At 5 squares per inch that is 40 columns by 52 rows of squares — over two thousand squares per page.
Why is every fifth line darker?
It is the convention on manufactured graph paper: counting in fives is much faster with anchor lines, the same reason rulers bold the inch marks. It makes reading coordinates off the page noticeably easier.
