Tubular locks, also known as radial locks, typically come in sizes based on the diameter of the keyway, most commonly 7-pin (with a 7.0 mm diameter) and 8-pin (with an 8.0 mm diameter). The most standard tubular lock size is 7/8 inch (about 22 mm) in diameter, but they can range from 5/8 inch (16 mm) to 1-1/8 inch (28 mm) depending on the application.
