"Never" isn't quite true here! Some do.
I usually keep everything aligned to an 8x8 grid so frame sizes and positions are always a multiple of 8, the actual sizes can be determined quite easily then.
Other than that, you'll usually have to cut and sort the frames manually (or use tools designed for the task).
When adding them to a game, you'd better make your own sheets out of the frames anyways, suited to your needs and without any overhead (text descriptions, spacing etc) and at best optimised for graphics cards (power of two dimensions).
