    Pipe sizes are determined by the btus required.

    Generally speaking, here's a chart:



    Stay in the middle, between minimum and maximum. Which means:

    1/2" = 2 gpm
    3/4" = 4 gpm
    1" = 8 gpm

    You need to FIRST do a scientific heat loss calculation to determine what size equipment, radiators, piping and pumps are needed.

    SlantFin has a free app that you can download. Disregard any quick, square footage calculators that you may find. They're worthless.
