Before you use the answer
Confirm the production specification with the printer or delivery platform before choosing dimensions. Keep trim, bleed, live area and pixel density distinct. Numerical consistency helps prevent avoidable rework, but a final proof remains necessary to judge the finished layout.
Layers, profiles, metadata and compression change the saved file size.

Why might a result be approximate?
Measurement uncertainty, ideal-model assumptions and floating-point rounding can all matter. Displaying more digits does not improve the original measurement.
