Understanding Your 3-Dart Average | Oche

The 3-dart average is the number every serious darts player lives by. It’s the headline stat on every broadcast and the first figure leagues quote. But plenty of players use it without really understanding what it measures — or why it moves the way it does. Here’s the full picture.

What it actually measures

Your 3-dart average is the average points you score per turn of three darts across a leg. It rolls scoring and finishing into one number, which is why it’s such a good single measure of overall standard. A higher average means you’re either scoring bigger, finishing in fewer darts, or both.

How it’s calculated

The formula is simple:

(Total points scored ÷ darts thrown) × 3

Say you win a 501 leg in 18 darts. You scored 501 points across those 18 darts, so:

• 501 ÷ 18 = 27.83 points per dart
• 27.83 × 3 = 83.5 three-dart average

That’s it. The maths is the same whether the leg took 12 darts or 30 — it always normalises to a per-three-dart figure so legs of different lengths are comparable.

3-dart average vs points-per-dart

Some apps and players quote points-per-dart instead. It’s the identical figure divided by three: a 90 average is 30 points per dart. Neither is “more correct” — just know which one you’re reading. The three-dart number is the convention in PDC stats and most leagues, so it’s the one to track. Our 3-dart average guide sticks to that standard.

Why the checkout matters so much

Because the average counts every dart including the winning double, a clean finish can lift your average sharply. The final turn often uses one or two darts instead of three, which shrinks the denominator and pushes the number up. This is why two players who score identically can have different averages — the one who finishes faster wins on the stat too. It’s also why your checkout percentage and your average are so closely linked.

Using it to track progress

A single leg’s average is noisy — one big finish or one bust swings it a lot. What matters is the trend over many sessions. Watch the rolling figure climb across weeks, not the spike from one good leg. Knowing what counts as good at your level helps too; our good darts average breakdown maps the bands from beginner to pro.

Let the maths run itself

Working out averages by hand mid-practice is a chore, and most people get it wrong. The Oche X01 scorer calculates your 3-dart average for every leg automatically and plots the trend in the stats dashboard, so you can focus on throwing while the numbers take care of themselves.
