Lets say you are buying an airplane, one has 1025 sq.in. of wing area, the other has 893 sq in of wing area. Now lets say they both weigh 10 lbs. = 160 ozs. The airplane with 1025 will have a loading of around 22.5 ozs. but the airplane with 893 will have a loading of around 26 ozs. In my opinion lighter loading is better, so I always buy or build to the lower wing loading. Keep in mind that is just my own opinion and there are lots of argument about that on RCU. I hope I have answered your question.
