To hit treble 20 more consistently, stop treating it as one lucky target and start training the miss pattern around it. Use the same stance, grip, sight line, release and follow-through for all three darts, then measure whether misses are mostly low, high, or drifting into 5 and 1.
Last reviewed: 23 August 2026. This guide is written for steel-tip players practising standard 501 scoring.
Quick answer
Treble 20 consistency comes from repeatability, not from aiming harder. The target is narrow. If your throw changes from dart to dart, the group will spread into single 20, 5, 1, or above the treble bed. Your first job is to make the miss predictable. Your second job is to make the miss smaller.
That means training in three layers: a stable throw, a precise T20 sight picture and a scoring rhythm that survives dart three. Most players lose treble-20 consistency because they steer the final dart, squeeze the grip, or change tempo after a good first dart.
Why treble 20 is the main scoring target
Treble 20 is worth 60, which makes it the highest single-dart score on a standard board. Three treble 20s make 180, the maximum visit in normal scoring. That is why most 501 players build their scoring game around the 20 segment.
However, treble 20 is not automatically the best target for every dart. If the bed is blocked, the marker dart is awkward or your line is drifting badly, moving to 19s can be the stronger percentage choice. Good scoring is not blind loyalty to T20; it is knowing when T20 is still the best route.
Start with the big 20
If you cannot land a high percentage of darts in the big 20 segment, treble 20 consistency is not the first problem. The treble is inside the scoring segment. Build the segment first, then shrink the target.
Throw 30 darts at big 20 and record how many stay in the segment. Do not count only trebles. Count how often you miss into 5, 1, above the board, or low into single 20. If more than half the darts are leaving the 20 segment, spend more time on big-number grouping before demanding T20 performance.
Pick a precise sight picture
Do not aim at the whole treble bed. Pick one small visual reference: the centre of treble 20, the lower wire, the upper wire, or the flight line of a previous dart if it is a useful marker. A smaller aiming reference makes feedback clearer.
This is not about freezing over the target. Over-aiming usually makes the arm tight. The aim point should give direction, then the throw should flow. If you stare until your hand stiffens, the sight picture is doing more harm than good.
Keep the same throw for dart three
Dart three exposes the truth. Many players throw dart one naturally, adjust dart two slightly, then force dart three because a 100, 140 or 180 is possible. That emotional change often causes the miss.
During practice, score the visit by rhythm as well as result. If dart three feels different, write it down. A visit with one treble and three identical throws may be more useful than a bigger score produced by a rushed third dart.
Read the miss pattern
| Miss pattern | Likely cause | First fix |
|---|---|---|
| Low into single 20 | Late release, short follow-through or a dropping elbow. | Finish the hand through the target. |
| High above treble 20 | Early release, lifting or forcing the dart. | Smooth the pull-back and release naturally. |
| Wide into 5 | Line drifting left for many right-handed players. | Check elbow path and shoulder alignment. |
| Wide into 1 | Line drifting right for many right-handed players. | Relax grip pressure and keep the hand path straight. |
| Random spread | Too many moving parts changing at once. | Return to stance and grip basics. |
The 90-dart T20 block
Use this drill twice a week. Throw 30 darts at big 20, 30 darts at treble 20 and 30 darts as 10 normal match-rhythm visits. Record trebles, total 20-segment hits and miss direction. Do not change technique halfway through unless the same miss appears for at least two blocks.
The first 30 darts tell you whether the general scoring segment is stable. The second 30 test the small target. The final 30 test whether you can keep the same throw across real visits. This separation matters because a player can hit treble 20 in isolated practice but lose the target once scoring pressure appears.
Use marker darts properly
A dart just below treble 20 can be a useful marker because it gives the next dart a visible reference. A dart blocking the bed can be a problem because it narrows the route. Strong players do not simply throw at the same spot regardless; they read the first dart and choose the next line.
If the first dart is upright and blocks the lower bed, the next dart may need to enter higher. If it lies flat below the bed, it may guide the next dart. The skill is not copying one entry angle. It is learning what your darts do on your board with your setup.
When to switch to 19s
Treble 20 is the main scoring target, but treble 19 is the most important cover shot. If T20 is blocked, your first dart is badly positioned, or your throw is repeatedly dragging into 1 and 5, switching to 19s can protect the visit.
This does not mean giving up on treble 20. It means playing percentage darts. Read the best numbers to aim for in darts for more context on scoring choices and cover targets.
Technique cues that help T20
Quiet stance: if your feet move, the shoulder line changes. Keep the base still enough that the throw can repeat.
Soft grip: squeezing the barrel often sends darts low or sideways. Hold the dart securely without locking the fingers.
Clean release: the dart should leave without being pushed. A forced wrist flick usually adds another variable.
Full follow-through: the hand should continue towards the target. If the hand stops early, the dart often drops into single 20.
What beginners should expect
Beginners should not judge progress by 180s. A better early target is more darts in the 20 segment, fewer misses into 5 and 1, and a gradually tighter group around the treble bed. A first 140 is good, but so is a run of steady 60s if the darts are grouped well.
If the throw still feels inconsistent, read why you cannot throw darts properly and the basic skills in darts. Treble 20 practice works best when stance, grip and release are already repeatable enough to give honest feedback.
What improving players should track
Improving players should track three numbers: T20 hits, total 20-segment hits and cover-shot decisions. If you hit only a few trebles but keep most darts in 20, the scoring base is improving. If trebles improve but cover decisions are poor, match scoring may still suffer.
Also track whether dart three changes. Write down visits where the final dart is rushed, steered or thrown with extra force. That note is often more useful than the score because it reveals pressure behaviour.
Equipment and setup checks
A stable setup makes T20 practice more reliable. A board with damaged wires or a badly worn 20 segment can increase bounce-outs and distort feedback. Poor lighting can also make the thin treble bed harder to sight cleanly.
Use dartboards if the 20 bed is worn, darts if you are comparing barrel grip and weight, dart sets for complete starter options and darts accessories for spare flights, stems and small setup changes.
One-week treble 20 plan
Day one: throw the 90-dart T20 block and record the baseline without changing anything.
Day two: practise big 20 grouping only. Keep the session simple and focus on the same release.
Day three: throw 10 visits at T20, then 10 visits switching to 19s whenever the first dart blocks the bed.
Day four: work on doubles. Scoring well only matters if you can finish legs.
Day five: repeat the 90-dart block and compare miss direction with day one.
Day six: play short 301 or 501 legs and make cover-shot decisions in real scoring context.
Day seven: review the numbers. Keep one cue for the next week, such as soft grip, full follow-through or calmer dart three.
Common T20 mistakes
- Changing too much: do not alter stance, grip and darts in the same practice block.
- Only counting trebles: track segment hits and miss direction as well.
- Ignoring 19s: cover shots protect bad visits and blocked beds.
- Steering the third dart: use the same rhythm even when a big score is possible.
- Practising when frustrated: tired, angry practice often teaches tension.
How T20 practice should change your match play
The point of T20 practice is not only to hit more 60s. It should also make your scoring decisions calmer. If your first dart lands neatly in single 20, stay composed and use the marker. If it blocks the treble bed, decide early whether the second dart still has a clean route or whether 19s give a better visit.
This is where practice becomes match value. A player who understands their miss pattern can make faster, better choices under pressure. If you know your normal miss is low into single 20, you can keep scoring without panic. If you know your line drifts into 1 after a tight grip, your cue is relaxation before dart two. The board is giving information; the skill is responding without turning the throw into a different action.

Bottom line
To hit treble 20 more consistently, train the whole scoring system: stable throw, precise sight picture, controlled dart three, honest miss tracking and sensible cover shots. The goal is not to force every dart into T20. The goal is to make the normal miss smaller until more visits stay in scoring control.

FAQ
How do you hit treble 20 consistently?
Use a repeatable stance, grip, release and follow-through, aim at one precise point in the bed and track whether misses are low, high, or drifting into 5 and 1.
Should beginners aim for treble 20?
Yes, but only after they can keep a reasonable number of darts in the big 20 segment. Build the segment before demanding the treble.
Why do I keep hitting 5 and 1?
Wide misses usually mean the throwing line, grip pressure or elbow path is changing. Track which side repeats before changing technique.
When should I switch from 20s to 19s?
Switch when the treble 20 bed is blocked, your marker dart creates a poor angle, or your current visit has a better percentage route through 19s.
