Isometric Graph Paper
Three sets of lines at 60°, with 6 mm triangles on A4 by default, so every face of a 3D sketch stays measurable.

In an isometric drawing the three axes are equally foreshortened, which sounds like a compromise and is actually the point: a length along any axis is drawn at the same scale as a length along either of the others. You can measure a finished sketch.
True perspective looks more natural but destroys that property — a line twice as far away is drawn less than half as long. Isometric paper trades realism for a drawing you can take dimensions off.
Anywhere a 3D shape needs to be communicated accurately rather than beautifully.
Every sheet here is free, adjustable and prints at exact scale.
5 to 7 mm suits most hand sketching; the 6 mm default gives about 36 columns of triangles across an A4 sheet. Go larger — 10 mm or more — for teaching and demonstration, smaller if you need a lot of detail on one sheet.
Keep them for boxy subjects: they give you the true vertical edges of walls, columns and machine parts. Turn them off and you get a plain triangular lattice, which is quieter under a drawing that is mostly diagonals.
It is what most people mean by 3D graph paper. Strictly, isometric is one of several axonometric projections, but it is the one that gets printed.
