A Golomb ruler of order m with length n may be optimal in either of two respects: [11]: 237 It may be optimally dense, exhibiting maximal m for the specific value of n, It may be optimally short, exhibiting minimal n for the specific value of m. The general term optimal Golomb ruler is used to refer to the second type of optimality.
Many US tapes also have special markings every 16 inches (406 mm), which is a US standard interval for studs in construction: three spaces of 16 inches make exactly 4 feet (1,219 mm) which is the US commercial width of a sheet of plywood, gyproc or particle board. A dual scale inch/centimeter tape measure.
