LP tank sizes can vary widely. Some homes may have as little as a 50-lb tank if only using it for supplemental heating, up to a 1,000-lb tank for homes running most appliances on LP. You will simply need to find out approximately how much propane you are currently using, and how ofter you would like have the tank(s) refilled to determine what size tank is best for you.

Thant depends on usage but the most common is two 100 pound tanks and using the old trick is tun one off till you run out and switch to the other one and swap it out but with the new top off deliverys that is not needed any more and many reduce the need for the second tank as we have a gas dryer a gas cook top and our BBQ Hooked in and found we only need one tank with a top off refill every 4 months
