The Sirus V3 Atmo runs 9 sizes, 1,150–2,350 cm², and changes proportion as it grows: aspect ratio runs 9.3 at one end of the range to 15.0 at the other, so its sizes differ in shape as well as in area.
Its 1,860 mm span is 62% wider than typical for the area — the median across the 25 current wings within 10% of its size is 1,150 mm.
