If you had a 4/12 pitch and the ridge was running the 20' direction and you were planning on a 12" overhang, your 2x6 rafters would be just shy of 9'-6" each. If your framing is 16" on center you will need 34 of them.

How do you determine pitch of roof?
The pitch of a roof is measure in a simple way. Rise over run. By this it means that, given the standard example of a 4/12 roof ,for every 12 inches or one foot of distance or run there is an according rise of 4 inches in height. If you wish to determine this you need to know the length of the rafters and then the height from the center of the rafter to the peak of the roof. For instance if the rafters happen to be 24 feet long that means that the run is 12 ft and if the height from the bottom of the rafter to the peak is 8 feet then you have a 8/12 pitch roof.
