Darts Three-Dart Average Calculator
The three-dart average is the single most important number in darts — it is how every player from beginner to world champion is rated. This calculator turns your total points scored and total darts thrown into a three-dart average and a points-per-dart figure.
How it works
The average normalises your scoring to a per-visit (three-dart) basis:
Points per dart = Total points / Total darts
Three-dart average = Points per dart * 3
= (Total points / Total darts) * 3In a 501 leg, the total points scored is always 501 (you must reduce exactly to zero), so a 501 leg finished in 18 darts gives 501 / 18 * 3 = 83.5. For multi-leg sessions, sum points and darts across all legs first.
Example and notes
A player who scores 1503 points across three 501 legs using a total of 45 darts has a points-per-dart of 1503 / 45 = 33.4, giving a three-dart average of 33.4 * 3 = 100.2. A perfect nine-dart 501 leg yields 501 / 9 * 3 = 167.0, the maximum possible single-leg average.
Tips: always include checkout darts in the total, since that is how official averages are computed. Tracking your average over many sessions is the cleanest way to measure improvement — focus on raising your scoring power (more treble-20s) and your checkout efficiency (fewer wasted darts on the double) to push the number up.
Average benchmarks across skill levels
The three-dart average is the standard way to compare players, and the ranges below give a sense of where you stand:
| Level | Approximate three-dart average |
|---|---|
| Casual beginner | 20 – 40 |
| Regular recreational player | 40 – 60 |
| Solid club player | 60 – 80 |
| Strong amateur / county level | 80 – 95 |
| Semi-professional | 95 – 100 |
| Professional tour level | 100 – 110+ |
| World-class match performance | 110+ |
A 167 average represents a perfect nine-dart 501 leg — the theoretical maximum for a single leg. In practice, even the best players in the world average well below this over a full match, as every missed double or suboptimal setup visit drags the figure down.
What moves the average up
The three-dart average is a product of two things:
- Scoring power — how consistently you hit the treble-20 (60 per dart), treble-19 (57 per dart), or other high-scoring segments during the scoring phase.
- Checkout efficiency — how many darts you need to finish once you are on a checkable score. Every extra dart thrown at a double without hitting it lowers your average.
For players below 60, scoring power is usually the main limiter — improving treble-20 accuracy adds points per visit rapidly. Above 80, checkout proficiency becomes the bigger differentiator, because scoring is already solid and the difference comes down to how cleanly and quickly you close out legs.
Tracking over time
To spot real improvement, track your average across entire sessions rather than individual legs. A single leg average can swing wildly — one 170 checkout inflates it, one visit of 3 drags it down. A session average across 10 or more legs gives a more stable signal. Month-to-month trends in your session average are the clearest measure of genuine progress.
