Free Online Graph Paper / Grid Paper PDFs
Downloadable and very printable, I find these PDFs extremely useful.
Square Graph Papers
Plain Graph Paper PDF Generator - Set your border and grid spacing (i.e. 4 lines per centimemter) to get as much graph as possible on your paper.
Graph Generator Lite - Specify the number of squares you want - and the size of them.
For those who want extra border on the left side of the page, and only need 2 different lineweights, try this experimental PDF generator.
Same as multi-width, with the ability to specify different colors per grid size.
Like normal graph paper - but with cross grids.
X and Y lines are configurable independently, so you can make tall or wide crosses.
Lined Paper with Light Verticals PDF Generator - Horizontal lines with vertical lines being in a lighter color. The weights of both the lines can be adjusted.
Grid-Lined PDF Generator - Multiple boxes per each writing line.
Axonometric (bisected) diamond PDF Generator You can make them without the vertical bisector as well.
Inverted Graph Paper
Like normal graph paper - but with dots instead of lines.
