A tile saw gauge has a receiver, an extension arm, and a slidable gauge. In one embodiment, the slidable gauge has one or more protrusions for fixing various lengths. The receiver may be permanently attached to a tile saw, such as by welding, or may removably attachable, such as by using screws, a bolt and nut, or similar mechanism. The tile saw gauge may be retrofitted on saws in the art, allowing tile saws in the market to make consistent cuts on larger tiles or tile lengths.
