If one takes that 19 inch width as being the outermost dimension of the flanges on each side of the rack, known to the industry as "ears", one can see where the number comes from. Of course, the bolt hole center dimension is the only one that is truly hard and fast as modern "designers" scrimp on every gram of steel or Aluminum they can (in all the wrong places), like idiots. Modern rack designs use at least three different attachment methodologies. The one I like the most is the cage nut method, as the captured nut is a case hardened, properly threaded component, which floats a bit in it location, allowing for mismatches to be more easily dealt with. The standard was for a #10 screw for a long time as well. I like, however, the newer 6mm screw variety, as it threads in much easier and is far less likely to jam up during installation or field servicing. The number ten screws simply bugger up too easily, and the holes are machine drill and tapped and they never change out the taps often enough and there is never a lead in chamfer on the holes, so screws and holes get messed up, especially when using power driver devices. The 6mm screws using the cage nut are rolled thread, hard screws and the cage nuts are all made with a proper lead in. Shtuff goes together much smoother.

Bicycles are also sold by inch sizes ("a 28-inch bike") intended as type specifications. An anecdote I heard a while ago was that one bus operator wrote in their terms and conditions that bikes "up to 20 inch" are free, meaning children's bikes. Somebody used this to say "by <insert old obscure definition of inch here>, my bike has just 19,5 inch wheels, so it's free", and got admitted. Stefan
