Which bed length do I have on my Ford F-150?

Measure from the inside of the bulkhead (the wall right behind the cab) to the inside of the closed tailgate, at the floor. Round to the nearest half-foot and match it to the bed options in the table above for your model year - the door-jamb tag or window sticker also states it if the truck still has one.

Will a 4x8 sheet fit flat?

Yes, with the tailgate closed - the Ford F-150's widest bed is 50.6 in between the wheel wells (over the 48 in a sheet needs) and 97.6 in long (over the 96 in a sheet needs), so a 4x8 sheet lies flat on the floor.
