By the sq. foot, measure your roof - length x width. the rolls are marked on how many sq. feet they will cover, just remember you have to lap each course a least 2in. , so take that into consideration.

Measure your roof. You need the Square feet. Width x Length.
Roofing felt comes in 100 Square foot rolls. Now don't fall into the trap of using your building dimensions as your square footage for the roof measurement. You have to measure the roof itself because of the overhangs and the pitch of the roof (pitch is the angle of the roof). If you are felting your roof I have to assume you will be putting shingles down next. Again the same measurement will work here for estimating how many squares will be needed for your roof. If you are going to be using 3 Tab shingles all you need is 15 pound felt. If you are going with Architectural you will need 30 pound felt. Oh yes be sure to over lap your felt by at least 2 inches but 4 inches is better.
Some will tell you that 30 pound felt is better even under 3 tab but that is not correct. To verify call a roofing material supplier not a Home Depot or Lowes but an actual roofing distributor. They can also deliver the shingles and felt to your site and put them on your roof for usually $1 more per square saving your back alot of pain.
Hope this helps.

Felt is sold in rolls that contain a given amount depending on the weight rating of the felt. Remember 1 square equals 100 square feet.
15 pound rating comes in 4 square rolls
30 pound rating comes in 2 square rolls.
Simply said 30 pound is best.
In Florida I use 30 pound felt to provide a better surface for the shingles regardless of if the shingles are standard 20 year 3 tab or 30 year Architectural or Dimensional style shingles.
The Architectural or Dimensional shingles are considerably heavier and seem to hold up better in the high winds of storms.

Some of your answers are great. Keep in mind that each peak must be measures individually to get your proper sq footage. Peak pitch plays a factor as well. Good Luck

There is a form you use when you go to buy the roofing that tells you how to do it.
