Most "printable graph paper" you find online is a fixed image or PDF scaled to whatever the original creator's printer happened to do — the grid on the page rarely matches the 5mm or quarter-inch it's labeled as. Sheetful builds the grid from scratch at the exact spacing you set, in real millimeters, so a 5mm grid prints as a 5mm grid regardless of your printer or paper size.
Graph paper is the default surface for anything that needs consistent scale: coordinate geometry and algebra, engineering sketches, circuit diagrams, needlework and cross-stitch charts, pixel art, or just keeping columns of numbers aligned. Set the grid spacing anywhere from 1.5mm up to 20mm, choose how often a heavier line marks off every 5th or 10th square, pick US Letter or A4, and adjust line weight and ink color to match how dark you want the grid to sit behind your work. The live preview on the right always shows exactly what will print.
5mm and 1cm (10mm) are the most common general-purpose sizes. Engineering and technical drawing often use finer grids around 2–2.5mm, while quilting and needlework charts typically want the grid to match the target stitch or block size exactly.
Yes. The grid is generated in real millimeters and rendered directly into the PDF at that scale — there's no image scaling step that can drift, so a 5mm setting prints as a true 5mm grid on both US Letter and A4.
Yes — use the line weight control (Fine, Regular, Bold) and the ink color swatches. A lighter, thinner grid works well if you plan to write or sketch over it; a bolder grid is easier to read at a glance for reference use.
