Open toolKDP margin checker
Every margin calculator repeats Amazon's table. The question that gets books rejected is whether your PDF actually meets it.
Open toolWord count to book pages — measured, not estimated
Most words-per-page tables are guesses. These numbers come from actually typesetting manuscripts at each trim size.

Open toolA Kindle Create alternative that doesn't lock you in
