How to Pace a Story in a Book

Every book is different and your main responsibilities to tell your story the best way that you can. The POV and the voice will dictate the pacing in your book are the two most important factors. How much time do we need to spend in this world to get what's going on? What kind of jam is the best kind of jam or whatever? And how much background do we needs to be immersed in the world it's all sorts of factors like that so i guess part of it is looking at your genre or your sub-genre and trying to copy how they do their pacing.
