So what is the actual limit if any? I just had a quick look at ISO 32000-2:2020 [1] and think the answer is none or implementation depended if you want. In the file format a media box is a rectangle, a rectangle is an array of four numbers, and a number is either an integer or a real. Numbers are represented as strings, so there is no a priori limit on their range and there seem to be no requirements on the minimum or maximum range of values an implementation has to support. The appendix only says that IEEE 754 is a commonly used format to represent reals and that this might impose limits.
