5 mm Isometric Dot Paper — Letter
Most engineering-class isometric pads use a 5 mm dot pitch, and it earns its keep as the all-round choice: fast 3D sketching, packaging nets, and hex or cube game-board layouts at accurate proportions. The spacing is tight enough for moderate detail yet open enough to track the three axes by eye, instead of counting dots one at a time.
