There’s a fair amount of variance between pixels due to the rubbery, waterproof coating. The figures given here are just guidelines, rounded up to the next whole millimeter (except for the mounting hole diameter). Allow yourself some extra “wiggle room” for spacing when planning an installation.
For mounting holes, 11.5 millimeters is a good guideline, or might go as narrow as 11 mm for a really firm grip, though at that size pixels will be hard to remove and the mounting flange may take some abuse in the process.
