Foil Chart
Every UniFoil wing and tail, side by side — area, span, chord, and aspect ratio. Find the right size for your weight, conditions, and discipline.
Find your wing
Three questions. One wing.
Where you are, what you ride, what you weigh. Answer those and the chart below gets a lot shorter.
01
Where are you at?
Each series is built for a stage of riding. Pick the one that matches you today, not the one you hope to grow into.
New to foiling
Progression
The easiest to ride. Low stall speed and forgiving pitch. The 170 is where most new foilers start.
Riding with confidence
Evolution
The step up. More glide and a higher top speed, with the same easy pump. The 135 is the all-rounder.
Chasing performance
Aggression · Quest
Aggression for the tightest turns in surf. Quest for 13:1 downwind glide that still surfs.
02
What do you ride?
Every wing crosses over, but each discipline has an obvious place to start.
| You ride | Start here | Also look at |
|---|---|---|
| Learning to foil | Progression 170 | Progression 200 for very small surf, dock starts and light-wind winging. |
| Prone surf | Progression 140 | Evolution 135 for more speed and glide. Aggression for the tightest lines. |
| Wing & parawing | Evolution 135 | Evolution 205 or 235 for the lightest wind. Aggression 150 to carve under power. |
| Downwind | Quest 135 | Evolution 155 for easy low-end lift. Aggression 170 to surf the bumps, not just connect them. |
| Foil Drive | Evolution | Draws about 10% less throttle than a comparable Progression. Aggression for a looser, surfier feel. |
| Wake | Aggression | Progression 125 as a first wake wing. See the wake setup. |
| Kite | Progression 170 | See the kite setup. |
03
What do you weigh?
Heavier rider, smaller waves or lighter wind: size up. Lighter rider, more power in the water, more experience: size down. The wing number is its area in square inches.
Aggression
- 105 — lighter riders, or experienced riders in bigger surf
- 130 — riders around 150 lb / 68 kg
- 150 — the everyday size around 175 lb / 79 kg
- 170 — heavier riders, lighter wind, downwind
Quest
- 110 — lighter riders, faster conditions
- 135 — medium-weight riders, the all-rounder
- 160 — heavier riders, lighter conditions
Progression · Evolution
- Each product page has a size guide by weight, discipline and skill level.

Fine-tune with the tail
- Progression 14.5 tail — slows the foil down and adds low-end lift, roughly half a wing size.
- Afterburner · Quantum — more top-end speed and tighter turns, with a little less low end.
