The Aero Free SLS has run 3 sizes, 800–1,250 cm², including discontinued sizes; aspect ratio moves 6.4–7.2 across the range.

Its 840 mm span is 12% narrower than typical for the area — the median across the 149 current wings within 10% of its size is 950 mm.

Closest wings from other brands

Projected and flat area run 3–8% apart. A marked area is one whose brand does not state which it publishes, so a comparison inside the area tolerance may be comparing unlike figures.
