    There're tons of tables out there, here's one. This one is for black iron pipe I believe, there're others for CSST, many mfgr's even provide an app that will size their product.

    Note that you must add length for each fitting, and (this is important) this table sizes lines for least pressure drop, meaning an installation that will Just Work. Some tables size gas lines for greatest pressure drop, meaning an installation that will Probably Work in Most Conditions. I'm not a fan of that. It will be, however, cheaper initially.
