Wing loading calculations
What is the formula for calculating wing loading?

Ounces divided by square feet wing area.

Wing Loading, Imperial
Loading (oz/sq.ft) = Weight(oz) / ( Wingspan(in) * Wing Chord(in) / 144 ) Wing Loading, Metric Loading (g/sq.dm) = Weight(g) / ( Wingspan(mm) * Wing Chord(mm) / 10000 )

So if all is right, a 17 lb airplane with 1420 square inches will have 25 oz/ft?

RE: Wing loading calculations
17 pound X 16 OZ/pound =272 ounces
1420 square inches / 144 sqin/sqft=9.861 sq ft 272/9.861=27.30 OZ/sqft

For future reference, here is an online way to calculate wing loading:

If your wing is not rectangular, the formula cited in post #3 doesn't really apply for it assumes a rectangular wing (i.e. wingspan X chord). The correct formula for wing loading is weight/wing area. If you know the actual wing area, you should use this. For example, if you had a wing with an aft swept leading edge, tapering to the tip, etc., then the formula from #3 wouldn't give the correct result. Use the wing area if you can determine it.

Ok, here a formula to calculate wing area in trapezoidal wings:
Area=( (chord at root +chord at tip)/2)* wingspan, ok more simple, add root to tip chord lenght, divide by two, and then multiply for wingspan

What is the typical wing load value of the giant scale aeroplane?
