A kind of tile · also called ceramic floor tile, ceramic wall tile

About
A standard ceramic tile is a flat square covering about a foot wide and under half an inch thick.
Ceramic tiles range in size from tiny mosaic pieces under 1 inch (2.5 cm) wide to large panels over 4 feet (1.2 m) across. Wall tiles are usually thinner and lighter because they do not have to support the weight of people and furniture. Even though an individual piece is easy to lift, a single box of these tiles often weighs over 40 pounds (18 kg).
From Wikipedia
Tiles are usually thin, square rectangular coverings manufactured from hard-wearing material such as ceramic, stone, metal, baked clay, or even glass. They are generally fixed in place in an array to cover roofs, floors, walls, edges, or other objects such as tabletops.

Quick answer
A standard floor tile measures 11.8 inches (0.3 m) across, sits 0.35 inches (0.009 m) thick, and weighs 4.0 pounds (1.8 kg). That makes it about as wide as a school ruler and roughly as heavy as a standard red brick.
