Flight Shapes by Surface Area: What Each One Does to the Back End
Flight shapes differ by measured face area, from around 24 cm² for a standard down to about 13 cm² for a super slim. More area means more drag and more stability, a flatter arrival angle and a wider stack in the board. Less area means the dart carries further and faster and forgives less. Mass differences between shapes are tiny — 0.12 g to 0.20 g at 100 micron — so the behaviour is almost all aerodynamic.
By the Darts Fella Editorial Team
A standard flight measures around 24 cm² of face area across its four wings. A super slim is around 13 cm². Everything else sits between those two numbers, and that number — not the name — is what determines how the dart behaves after it leaves your hand.
More area drags harder. The dart decelerates faster, the tail is pulled into line more aggressively, and the dart arrives at a steeper nose-down angle. Less area means the dart holds speed, flies flatter, and does less to correct a poor release.
Mass barely enters into it. The whole range spans roughly 0.12 g to 0.20 g at 100 micron thickness — under a tenth of a gram between the biggest and the smallest. Anybody telling you a flight change altered the weight of their dart in a meaningful way is describing something else.
Names describe silhouettes, area describes behaviour
The naming is a mess and it's nobody's fault in particular. "No. 6" and "standard" mean the same thing. "Pear" and "No. 2" overlap depending on maker. "Slim" from one brand can be larger than "kite" from another. Two flights sold under the same name can be 10% apart in area, which is enough to be felt.
Measuring is straightforward: lay the flight flat before folding, and measure the total face area of the four wings on one side. That gives a single figure you can compare across brands regardless of what the packet calls it. Expect around ±0.4 cm² between brands using the same shape name — real variation, not measurement error.
Once you're working in cm², the choice becomes a straight trade. You are buying deceleration and correction, or you are buying speed and reach. Pick which problem you have.

The area figures assume a mainstream flight in each shape. Treat them as the centre of a range rather than a spec, and if you're comparing two specific flights, measure both — that's the only way to know which is genuinely larger.
Note how narrow the mass column is. From standard to super slim you save 0.08 g. On a 23 g assembled dart, that's a third of a percent. If a flight change transformed how your darts fly, it was drag, not weight.
Silhouette dimensions
The area number tells you how much drag. The shape of that area tells you where the drag acts, which is why two flights of similar area can behave differently.
Shape Wing height (mm) Maximum width (mm) Rear edge width (mm) Where the area sits Consequence Standard 44 44 44 Even, squared off at the rear Maximum correcting force at the very back of the dart Teardrop 45 42 31 Widest just forward of the rear edge Slightly gentler correction; less to clip on a tight stack Vortex 46 40 34 Concentrated in a narrow band with a curved trailing edge Encourages rotation, which some players feel as smoothness Kite 46 38 22 Widest at mid-wing, tapering to a narrow tail Correction acts further forward; flatter trajectory than standard Pear 43 37 37 Rounded and compact, rear-biased Small but square-tailed; useful compromise on crowded trebles Slim 47 28 28 Long and narrow, evenly distributed Minimal correction, minimal obstruction to the next dart Super slim / nano 47 22 22 Very narrow strip Almost no correction; buys the tightest possible stack If your problem is darts deflecting off the flights already in the board rather than flying badly, choose from the bottom three rows on rear-edge width alone. That last point deserves emphasis because it's the reason a lot of good players run slim flights they don't aerodynamically need. Three darts in a treble 20 bed occupy a space roughly 18 mm across. A standard flight has a 44 mm rear edge. The second and third darts are not fighting the air, they're fighting the first dart's flight — and a slim flight simply removes the obstacle.
Thickness and material
Thickness is measured in microns and it changes durability, mass and rigidity — but not area, and therefore not the fundamental behaviour.
Type Thickness Mass, standard shape (g) Rigidity Typical life Best for Thin polyester 75 micron 0.15 Low — creases readily Days to a couple of weeks Cheap practice; players who deliberately want a soft flight Standard polyester 100 micron 0.20 Medium Two to six weeks of regular play The default. Most flights sold are this Thick polyester 150 micron 0.30 High — holds shape after a strike One to three months Players who split flights often; heavier back end Dimpled / textured 100-150 micron 0.22 - 0.32 Medium to high Similar to smooth of the same thickness Slightly more surface turbulence; largely a feel preference Moulded one-piece Rigid, not sheet 0.28 - 0.40 Very high — will not crease Months, until struck badly Players who hate re-folding; less forgiving on a direct hit Integrated flight-and-shaft Rigid moulded 0.55 - 0.90 combined Very high Months Simplicity; you lose the ability to tune shaft and flight separately Pick thickness by how often you split flights, not by how you want the dart to fly — the aerodynamic choice is the shape table above. Pairing flight to shaft
Flight and shaft act together and choosing one in isolation is how people end up with a dart that behaves worse after two purchases than it did before either.
The rule that holds: a large flight on a long shaft gives you too much back end. The correcting force sits a long way behind the balance point, the dart over-corrects, and you get a pronounced nose-down arrival and a tail that whips. It also occupies enormous space in the board. Standard flights want short shafts.
Going the other way, a very small flight on a very short shaft gives you almost nothing to stabilise with. The dart holds whatever attitude your hand gave it, which is excellent if your release is clean and unforgiving if it isn't. Slim flights want length behind them.
The middle — kite or pear on an intermediate or medium shaft — is where most players should start and where most of them end up. It is not a lack of imagination. It's the combination that asks least of your release while still stacking acceptably.
One practical caution: change one variable at a time. Swapping shaft and flight together and then judging the result tells you nothing about which change did what, and you'll be back at the shop in a fortnight.
What a flight problem looks like in the board
Darts sticking in nose-up, with the tail low: not enough drag at the back. Go up the area table one step, or shorten the shaft.
Darts arriving very steeply nose-down and burying deep: too much drag, or too much shaft behind too much flight. Go down a step in area.
A visible wobble or corkscrew in the last third of the flight path: usually a damaged flight rather than a wrong one. Check all four wings sit at 90° to each other and that none is creased at the root.
Second and third darts deflecting off the first: this is a stacking problem, not a flight-behaviour problem. Read the rear-edge width column and go narrower.
Darts that fly beautifully then drop out of the board: not a flight issue at all — that's a blunt or hooked point, or a tired board.
Inconsistent flight-to-flight behaviour within one set: check the flights are actually the same shape. Mixed sets happen more often than you'd think, and a standard among three kites will be visibly different in the air.
Replacing flights before they cost you
Flights are the cheapest thing on the dart and the most neglected. A creased wing changes the drag on one side, which puts a small persistent bias into every throw with that dart — and because it's one dart in three, you'll blame yourself rather than the equipment.
Check before every session by standing the dart on its flights on a flat surface. If it stands square and all four wings are at right angles, it's fine. If it leans, the flight is done. That takes four seconds a dart and it's the highest-value habit in the whole equipment side of the game.
Flight protectors — small rings that clip over the flight where it meets the shaft — extend life considerably by stopping the root from splitting when another dart clips it. They add roughly 0.05 g each and sit right at the back, so they do move the balance rearward a touch. Worth it for most players, and worth knowing about if you're chasing a specific balance point.
Buy flights in bulk and in one shape. The temptation to buy variety packs and experiment is strong; resist it until you've settled, because the fastest way to never learn what suits you is to change the flight every time the darts misbehave.
