A tile measuring device including a pair of transparent, slidably connected plates having reference indicia thereon. A rotatable handle, defining a threaded aperture, is mounted on a threaded member, fixed to the bottom plate, and is rotatably adjustable from a first position wherein the top and bottom plates are fixedly secured relative to one another, to a second position wherein the top and bottom plates may be slidably adjusted. The top and bottom plates each include linear dimension markings along at least one side of the device such that when the top and bottom plates are telescopically adjusted and fixed relative to one another the markings provide linear dimension references. In addition, each of the top and bottom plates include longitudinal markings for use in cutting notches in tiles. An adjustable template according to the present invention is particularly useful in measuring and cutting tile for installation around the periphery of a tiled area adjacent to a boundary, such as a wall, an obstruction, or the like, while accounting for the size of grout joints on either side of the tile.
