Brick vs Disc golf driver: length comparison
The length of a brick is about 1.02 times the outside diameter of a disc golf driver.
A brick is a rectangular block made from clay or concrete, commonly used in building walls and structures.
A disc golf driver is a specialised flying disc designed for long-distance throws in the sport of disc golf.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.

Length: 21.5 cm; example.
A 215 mm long, 2 kg example; material and holes alter mass.
Defined examples — our methodology
The marked length is calibrated. Unmeasured illustration details are representative.
Disc golf driver
Specified outside diameter: 21.1 cm; specified specimen; range 21 cm–21.3 cm.
A defined PDGA-approved driver 21.1 cm in outside diameter and 175 g, near the permitted maximum mass for that diameter. Rim profile varies by approved model; printed graphics are not part of the measurement.
