KT Foiling Halo 670 · 725 mm span · traced from the manufacturer’s plan view · drawn nose-up, wings aligned on the mid-point of the root chord (the dotted line). ▬ GONG Ypra Freestyle V3 M · 730 mm

The Halo runs 4 sizes, 550–950 cm², and holds its proportions across the range: every size publishes an aspect ratio within 5% of the others.

Its 725 mm span is 7% narrower than typical for the area — the median across the 92 current wings within 10% of its size is 780 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.

Current wings from other brands within ±5% of area and ±8% of aspect ratio of the KT Foiling Halo 670, closest first.
