Graph paper, grid paper and dot grid
Two names for one paper, and the one that is genuinely different.
Short answer
Graph paper and grid paper are the same: a sheet of evenly spaced squares, also sold as quad-ruled paper. Dot grid prints only a dot where the lines would cross, usually 5 mm apart, so you get the same alignment without lines showing through your writing and drawing, which is why bullet journals use it.
The kinds of grid paper, side by side
| Paper | What is printed | Best for |
|---|---|---|
| Graph or grid paper | Full lines forming squares, often a bold line every fifth | Maths, plotting, scale drawings, knitting and pixel charts |
| Quad-ruled paper | Graph paper with 4 or 5 squares per inch | School and office notebooks in the US |
| Dot grid | A dot at each intersection, usually 5 mm apart | Bullet journals, planners, lettering, sketching, wireframes |
| Engineering paper | Bold squares with fine subdivisions, on pale green | Engineering and physics work, plotting to two scales |
| Isometric paper | Lines at 30 degrees forming triangles | 3D sketches, product and game design |
Dot grid or graph paper?
Graph paper wins where the lines are the point: plotting a function, drawing to scale, counting squares for a chart. Dot grid wins where the page is mostly writing or drawing and the grid is only there to keep things straight. The dots guide a box, a column or a heading, then disappear from view once there is ink on the page, so a dot grid page looks like a clean page with good alignment rather than a sheet of squares.
Dot spacing for a bullet journal
5 mm between dots is the standard in almost every bullet journal notebook, and it matches a comfortable handwriting size: one line of writing per row of dots. People with larger handwriting use 6 or 7 mm; 4 mm suits small writing and dense layouts. A US Letter page at 5 mm with a 12 mm margin holds 38 × 51 dots.
Is graph paper better for maths?
For graphs, geometry and keeping columns of working aligned, yes, and 5 mm or quarter-inch squares are the usual choice. Many teachers ask for it for long division and fractions because each digit gets its own square.
