Pick square, dot, isometric, hexagon or polar paper, set the spacing in mm or inches, and download it as a PDF or PNG.
To make printable graph paper, choose the grid type and the spacing between lines, and the tool draws a full page of it as a PDF you can print at 100 percent. The grid is fitted to the printable area inside your margin: it uses only whole squares, then centres the block so the left and right gaps match. For example, A4 portrait with a 10 mm margin leaves an area of 190 by 277 mm. At 5 mm spacing that holds 38 squares across and 55 down, which is 2,090 squares, and the leftover 2 mm at the bottom is split top and bottom. Setting the heavier line to every 5 means every fifth line is drawn twice as thick, which gives the familiar 25 mm blocks. Set it to 0 to draw all lines the same.
Square grid draws vertical and horizontal lines. Dot grid puts a dot where the lines would cross, and the heavier setting makes every Nth dot larger in both directions. Isometric paper is a triangular lattice: horizontal lines plus two sets of lines at 60 degrees, and the spacing is the side of one triangle, so the rows are 0.866 times the spacing apart. Hexagon paper tiles regular hexagons with the spacing as the length of one side, and only whole hexagons are drawn. Polar paper draws circles around the page centre, one per spacing step, with 12, 24 or 36 spokes, which is a spoke every 30, 15 or 10 degrees. Polar circles stop at the largest one that fits the margin.
Spacing can be typed in millimetres or inches. Switching the unit converts the number, so 5 mm becomes 0.197 in. The smallest spacing is 1 mm for square, isometric and polar paper and 2 mm for dot and hexagon paper, because below that a page holds tens of thousands of marks and prints as a grey blur. If you type less, the tool uses the smallest and says so. The largest is 50 mm. Pages are A4 (210 by 297 mm) or US Letter (8.5 by 11 in), portrait or landscape. The margin runs from 0 to 30 mm. Line weights are 0.25, 0.5 and 1 point. The PNG is made at 200 dots per inch, about 1654 by 2339 pixels on A4.
Print the PDF with scaling set to Actual size or 100 percent. If the printer is set to Fit to page, it shrinks the page a little and a 5 mm square comes out slightly smaller. Many home printers cannot print to the paper edge, so a margin of at least 5 mm avoids cut-off lines. The tool does not number the axes, draw graphs from equations or make logarithmic paper. It draws one page per download, with no header, name or date fields. The PDF is built in this tab from the settings you chose, with no upload, and the preview is the same drawing that goes into the file.
Leave Paper on Square grid, set Spacing to 5 and the unit to Millimetres, choose A4 and press Download PDF. With a 10 mm margin you get 38 squares across and 55 down, and every fifth line is heavier to mark 25 mm blocks.
Choose Inches as the unit and type 0.25 as the spacing, then pick Letter. A quarter inch is 6.35 mm. With a 10 mm margin, a Letter portrait page fits 30 squares across and 40 down.
Graph paper draws the full lines. Dot grid paper draws only a dot at each crossing, so there is less ink and less to look at behind handwriting or sketches. Dot paper allows a minimum of 2 mm spacing; square paper allows 1 mm.
Choose Isometric and set the spacing, for example 5 mm. The tool draws horizontal lines and two sets of lines at 60 degrees, so each triangle has sides of 5 mm. The Heavier line every setting, 5 by default, marks every fifth horizontal row.
The printer scaled the page. Set printing to Actual size or 100 percent instead of Fit to page. Then measure ten squares: they should be 50 mm.
