RC Wing Loading Calculator
Compute wing loading in g/dm², oz/ft² or kg/m² from aircraft mass and wing area.
Aircraft
Ready-to-fly mass including battery.

Wing loading
62.5g/dm²
(20.48 oz/ft², 0.63 kg/m²)
Higher loading generally means faster, less forgiving flight.
Formula
- 1.
Wing Loading (g/dm²) = Mass (g) / Wing Area (dm²) - 2.
oz/ft² = g/dm² × 0.327706; kg/m² = g/dm² / 100
Worked example
- 1.Inputs: 2500 g, 40 dm².
- 2.Loading = 2500 / 40 = 62.5 g/dm² ≈ 20.5 oz/ft².
Assumptions and limits
- Compare within the same aircraft class — a trainer and a jet live in different loading bands.
- Manufacturer specs may quote different units; convert before comparing.

FAQ
What loading is safe for a trainer?
Trainers typically fly light — check the kit manual; the calculator only computes the figure.
Assumptions
- Mass is the ready-to-fly figure.
- Wing area counts the lifting surface you enter.
