Why Do My Darts Bounce Out (and How to Stop It)

Darts bounce out for five fixable reasons: the point hits the metal wire instead of the sisal, the point is dull or bent, the throw is too hard and arrives at a flat angle, the dartboard is worn or dry, or the dart is colliding with an already-grouped flight. Most bounce-outs are solved by sharpening points and adjusting the board, not by buying new darts.

What Are the 5 Causes of Bounce-Outs, and How Do You Fix Each?

The five bounce-out causes each have a distinct fix. The table below pairs every cause with its first-line fix and a rough indicator of how often it is the real culprit, so you can rule causes in or out quickly before changing anything about your equipment.

Why Do Darts Bounce Off the Wire?

Darts bounce off the wire because the point lands on a metal divider (the spider) rather than on the sisal, and a blunt point has no edge to slide along the metal into the board. According to dartboard construction guides, thicker wire exposes more surface area, so the dart contacts metal more often and deflects more readily. A sharp point that grazes the same wire is far more likely to slide off it and bite into the fibres.

Wire thickness is set by the dartboard, not the dart. Older and budget boards use round wire stapled to the surface, which has the thickest profile and the most exposed metal. Premium competition boards use staple-free blade wire embedded directly into the sisal; multiple construction guides describe blade wire as roughly 50% thinner than round wire, with an angled profile designed to guide the point into the board instead of deflecting it. A thinner wire bed gives you a smaller metal target to hit.

The cheapest fix for wire bounce-outs is sharpening, not a new board. A correctly sharpened point presents a fine leading edge that slides along the wire and into the sisal, which is why sharpened darts are reported to seat where blunt darts ping away. Replace the board only when the bounce-outs persist after sharpening and the board is clearly old.

How Do You Sharpen a Dull or Bent Point Correctly?

Sharpen a steel point to a slightly rounded tip, not a needle. A dart point is never meant to be needle-sharp: a needle-sharp tip is reported to bounce straight back out, and a flat or blunt tip cannot grip the sisal. The target shape is a fine, slightly rounded cone, free of burrs.

• Use a dart sharpener, not a household abrasive. A cylindrical or bowl-shaped stone sharpener cradles the point at the correct angle. Grind in soft, steady, circular movements for roughly 10 to 20 seconds.
• Remove every burr. Burrs are tiny metal hooks that form when a point strikes a hard floor or wall. Run a finger along the tip; if it feels rough or jagged, keep working until it is smooth. Burrs both cause bounce-outs and tear sisal fibres out of the board on removal.
• Check after any dart hits the floor. A dropped dart is the single most common moment a burr forms, so inspect the point before the next throw.
• Re-sharpen after heavy sessions or whenever you notice more wire bounce-outs than usual. Higher-spec points generally need more frequent attention than soft brass points.

A bent point is a different problem from a dull one. A slightly bent point can be straightened, but a point that is visibly off-axis sends the dart in at a skewed angle and will not seat reliably. On a fixed-point dart, a badly bent point usually means re-pointing or replacing the dart. On a dart with an interchangeable point system, a bent point is a 30-second swap with a pocket tool, which is the main practical advantage of those systems for hard throwers.

Can Throwing Too Hard Cause Bounce-Outs?

Yes. Throwing too hard flattens the dart's trajectory, and a flat dart arrives at a shallow angle that deflects off the wire instead of sinking in. The reported ideal entry angle is between 15 and 45 degrees from the board face. The harder you throw, the less arc the dart has, so an over-hard throw pushes the entry angle toward the shallow, deflection-prone end of that range.

The fix is partly technique and partly equipment. On technique, ease the throw force and let the dart travel on a slight downward arc into the board rather than firing it flat like a bullet. A consistent release and follow-through matter more than power; our dart grip position guide covers how grip placement affects a clean, repeatable release.

On equipment, a heavier barrel adds momentum without extra force. Moving from a 20g barrel to a 24g barrel is reported to give the dart noticeably more momentum at the same throw effort, helping it carry through the wire and seat rather than deflect. Heavier darts also tend to fly with a slightly more pronounced arc, which nudges the entry angle back into the productive 15-to-45-degree window.

Does an Old Dartboard Cause Bounce-Outs?

An old or dry dartboard causes bounce-outs because worn sisal loses its self-healing grip. Sisal fibres naturally close around the point and recover after each dart is pulled, but with age and heavy use the fibres stretch, dry out, and harden. Hardened fibres resist the point, so darts seat shallowly or bounce off the surface even on a clean, well-angled throw.

Board rotation is the highest-value free fix here. Rotating the dartboard spreads wear across all segments instead of destroying the 20, treble 20, and bullseye, and it gives stressed fibres time to recover their self-healing. Maintenance guides recommend rotating roughly weekly for daily play and every one to two weeks for a board used a few times a week. Rotate the number ring, not the board mount, so the scoring layout stays correct.

Replace the board when rotation no longer helps. A dartboard with visibly thinning sisal, packed-down craters in the high-scoring zones, or a hard glazed surface has reached the end of its self-healing life. At that point a fresh sisal board, ideally a staple-free blade-wire model, removes both the worn-fibre and the thick-wire causes at once.

Why Do Darts Bounce Off My Other Darts?

Darts bounce off your other darts when a tight grouping leaves no clear sisal for the incoming point, so it strikes a stuck flight or shaft and deflects. This is a sign of good grouping, not bad throwing, and it is the one bounce-out cause that gets worse as you improve.

Spinning shafts and spinning flights are the targeted fix. A spinning shaft lets the flight of an already-stuck dart rotate out of the path of the incoming dart, so the new dart slips past instead of deflecting. Equipment guides report that spinning shafts reduce torn flights and decrease the chance of a bounce-out on a tight second or third dart, without changing how the dart flies through the air.

Movable-point darts are a separate, more specialised option. A movable or spring-loaded point retracts slightly on impact, absorbing some of the collision energy so the point is more likely to find grip in the sisal. Movable points address general bounce-outs rather than grouping collisions specifically, and many competition players still prefer fixed points for their predictability, so treat them as an experiment rather than a default.

When Should You Change the Point or Try Movable Points?

Change a steel point when it is bent off-axis, repeatedly burrs after sharpening, or has worn too short to seat. On fixed-point darts that means a re-point service or a new set. On darts built around interchangeable point systems such as Target Swiss Point, Harrows Quick Point, or Winmau Switch Point, a damaged point is a tool-free swap in under 30 seconds, which is why hard throwers and league players gravitate to those systems.

Our database includes a large selection of darts built around these interchangeable systems, including Target Swiss Point models, Harrows Quick Point models co-developed with Ryan Searle, and Winmau Switch Point barrels. Filtering by tip system lets you choose a barrel where bent or worn points are a quick fix rather than a reason to retire the dart.

Consider movable or spinning-point darts only after the basics are covered. Sharpening, throw angle, and board rotation resolve most bounce-outs at no cost. Movable points and spinning shafts are worth trying when bounce-outs persist on a healthy, well-angled throw, or specifically when tight groupings cause dart-on-dart deflections. If you are still dialling in your overall setup, the dart setup guide walks through barrel, shaft, and flight choices as one system.
