What is wing loading in skydiving?

Wing loading (WL) is the ratio between a skydiver's exit weight (body + gear, in pounds) and the main canopy surface (in square feet). It is expressed in lbs/sq ft. It drives flight speed, control responsiveness and required flare technique. It is one of the most important canopy-safety parameters.

What is the wing loading formula?

WL = exit weight (lbs) / canopy surface (sq ft). Exit weight is body weight plus the full gear (container, main, reserve, AAD, helmet, altimeter, suit — typically 10–15 kg). To convert kg to lbs: kg × 2.2046 = lbs.

What wing loading is right for a beginner?

For AFF students and novices (< 100 jumps) the recommended wing loading is below 1.0 lbs/sq ft, typically 0.7–0.9. Between 100 and 200 jumps you can step up to 1.0–1.2 after consolidation. Above 1.2 a basic canopy course should be completed.

Is wing loading measured in lbs/sq ft or kg/m²?

The international skydiving standard is lbs/sq ft (imperial), used by Italian schools too because canopies are manufactured and sized in the US. Metric reference: 1 lbs/sq ft ≈ 4.88 kg/m². Quota 4000 surfaces both units in the calculator.

How much does full gear weigh?

Typically 10–15 kg, including: container with main and reserve (~7–9 kg), AAD (~120 g), helmet (~600–900 g), altimeter (~100 g), freefall suit (~1 kg). Weight varies with canopy size and container model.

Formula

WL=exit weight (lbs)canopy surface (sq ft)

Exit weight = body weight + full gear (10–15 kg). Conversion: 1 kg × 2.2046 = lbs.

Your body weightkg

Full gear weightkg

Typical: 10–15 kg. Includes container + main + reserve + AAD + helmet + altimeter + suit.

Main canopy surfacesq ft

The international standard for canopy surface is sq ft (square feet). A '190' canopy means 190 sq ft.

Progressive thresholds based on USPA Skydiver's Information Manual (Section 6, Canopy Skills) and Brian Germain's recommendations ("The Parachute and its Pilot"). Values are conservative: each dropzone and jumpmaster may adopt tighter thresholds depending on weather, traffic and landing conditions.

Level	Jumps	WL (lbs/sq ft)	Notes
Student / Beginner	0–100	< 1.0	Canopies 210–260 sq ft, slow landings, wide margins.
Novice	100–200	1.0–1.2	Transition, basic canopy course recommended.
Intermediate	200–500	1.2–1.4	Higher responsiveness, canopy traffic awareness.
Advanced	500–1000	1.4–1.7	Performance canopies, advanced canopy course.
Expert / HP	1000+	> 1.7	Swooping / pro, reduced margins.
