Thanks to all responses.The maximum spans in the table above are for the horizontal distance the rafter can span (NOT the diagonal distance or actual length of the rafter). So if your house is 26 feet wide and the roof ridge beam is centered on the house, you will need a rafter that can span 13 feet. Let's use this example and find a size of rafter that will work.

Rafters will be 2' on center with 1' overhangs. It will be a shingled roof with three tabs. The only other weight to be supported by the roof will be bats of insulation and an air handler/duct system. The HVAC system will come in at 300-350 lbs max.

To get the same square footage, the correct max load per side of the hip is 9'/12.73' x 4.5'=3.184 ft at the ridge. 1/2 x 3.182' x 12.73' = 20.25 sq ft. That gives 3.182' x 2 sides = 6.36' in this case. Of course, the other answers will work, but this way can help you sharpen your pencil if you start to get huge beam sizes.
