1. A tile leveling device comprising:
a body defining an open window;
a base orthogonally coupled to the body, the base extending to a front of the body and the base extending to a rear of the body;
a base to body coupling including a frangible breakaway section, the base and body being integral prior to frangible separation, the frangible breakaway section, upon breaking, frangibly separating the body from the base;
at least one of a first through notch and a second through notch being positioned in the base;
the first through notch traversing the base toward the front of the body;
the second through notch traversing the base toward the rear of the body;
a combination of the first through notch and the second through notch being configured to provide a majority of tile-to-mortar-to-subfloor contact for the leveling device;
a front spacing pad integral with the body and extending from the front thereof;
a rear spacing pad integral with the body and extending from the rear thereof;
the combination of the front spacing pad, the body, and the rear spacing pad setting a predetermined joint distance that is greater than a thickness of the body for the tile leveling device within a single product; and
a wedge device including a wedge member having a tapered surface configured to penetrate the open window and exert force against at least one tile.
