DartScore.uk3-Dart Average Calculator
Last updated 10 November 2026
The 3-dart average is the most widely used measure of how well someone plays darts. Use either calculator below: one works from your points and darts thrown, the other from a finished leg.
From points and darts thrown
From a finished leg
How the average is calculated
The formula is total points ÷ darts thrown × 3. Multiplying by three turns “points per dart” into “points per turn”, which is the figure people quote.
Example: in three turns you score 60, 45 and 100. That is 205 points from 9 darts. 205 ÷ 9 = 22.78 points per dart, and × 3 = a 3-dart average of 68.33.
Count every dart you throw, including the ones that miss and the ones in a turn that busts. Excluding bad darts flatters the number and makes it less useful.
Averages and how many darts a 501 leg takes
This table divides 501 by each average to show roughly how many darts a leg takes. It assumes you hit your double first time, so real legs take a few darts more.
| 3-dart average | Points per dart | Approx. darts for 501 | Approx. turns |
|---|---|---|---|
| 30 | 10.0 | 50 | 17 |
| 40 | 13.3 | 38 | 13 |
| 50 | 16.7 | 30 | 11 |
| 60 | 20.0 | 25 | 9 |
| 70 | 23.3 | 21 | 8 |
| 80 | 26.7 | 19 | 7 |
| 90 | 30.0 | 17 | 6 |
| 100 | 33.3 | 15 | 6 |
| 110 | 36.7 | 14 | 5 |
The fastest possible leg of 501 takes nine darts, which is a 3-dart average of 167.
Making sense of your average
There is no official grading, but as a rough guide, casual players often average somewhere between 30 and 50, regular league players between 50 and 80, and professionals on television around 90 to 100 or more. The most useful comparison is with yourself: track your average over many legs and look at the trend rather than any single game.
The DartScore.uk scoreboard works out your average automatically for every game you play. See darts statistics explained for the other numbers it tracks.
Frequently asked questions
How do you calculate a 3-dart average?

What is a good darts average?
It depends on your level. As a rough guide, casual players often average 30 to 50, league players 50 to 80 and top professionals 90 to 100 or more.
Should busted darts count in my average?
Yes. Every dart thrown should count, otherwise your average looks better than your real scoring.
