About CustomGraph
Graph paper that works for you
CustomGraph is a free online graph paper generator. Built to give students, educators, engineers, and researchers complete control over every detail of their printable graph paper — no software, no account, no cost.
Mission
Why CustomGraph exists
Before CustomGraph, getting the right graph paper meant either using whatever was in the stationery cupboard, or spending time with a ruler and a pen. Pre-printed graph paper comes in limited formats — usually 1 cm blue Cartesian on A4 — with no options for color, line weight, or grid density.
The CustomGraph application was built to solve this. It generates crisp, vector-quality PDF graph paper in over 800 million configurations — five paper types, ten colors, nine grid sizes, five paper formats, two orientations, two justifications, and five line weights.
The application was designed from the beginning with overhead projector transparency slides and laminated field data-collection stock in mind — two formats that standard stationery stores never stock in the right configuration.
