The JAM HM Carbon runs 3 sizes, 1,400–1,900 cm², and holds its proportions across the range: every size publishes an aspect ratio within 5% of the others.
Its 1,400 mm span is 8% wider than typical for the area — the median across the 58 current wings within 10% of its size is 1,300 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.
