Darts 501 Leg Average Calculator
Convert the number of darts you threw to check out a 501 leg into your three-dart average — the number the pros are judged on.
How it works
Three-dart average = (starting score ÷ darts thrown) × 3 · Points per dart = starting score ÷ darts
The three-dart average is darts’ headline stat: total points scored divided by darts thrown, scaled to a full three-dart visit. In a single 501 leg the points scored equal the starting score, so the average is simply 501 divided by your dart count times three. A perfect nine-dart leg is a 167 average; club players typically sit in the 40–60 range, and a 100+ average is professional class.
Worked example
Checking out 501 in 15 darts gives (501 ÷ 15) × 3 = 100.2. Every dart was worth 33.4 points, spread over 5 visits — a genuinely elite leg.
Frequently asked questions
What is a good three-dart average?
Recreational players often average 30–50, solid club players 60–80, and touring professionals 90–105. The all-time competitive nine-darter is a 167 average, the ceiling for a 501 leg.
Why multiply by three?
Averages are quoted per three-dart visit, not per dart, because players throw three darts per turn. Multiplying the per-dart rate by three puts your number on the same scale used on TV.
Does this work for 301 legs?
Yes — set the starting score to 301. The formula divides whatever you started from by the darts you used, so it handles 301, 501, 701 and practice targets alike.
