Not exactly sure what you are looking for, but if you are wondering about properly sizing a furnace for your home the best method to do that is to have a certified HVAC tech perform a manual J calculation.
If you are wondering about why you need to size a furnace, the simple answer is that too small of a furnace will work too hard to maintain heat and will break down more often and need to be replaced sooner. Too large of a furnace is like driving a semi truck with the brakes on the whole time. It will hurt the furnace and cause it to run inefficiently.
Hope this helps.
