The Sonar SF runs 6 sizes, 530–1,230 cm², and changes proportion as it grows: aspect ratio runs 7.1 at one end of the range to 10.6 at the other, so its sizes differ in shape as well as in area.
Its 750 mm span is 8% wider than typical for the area — the median across the 52 current wings within 10% of its size is 697 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.
