Darts Checkout Calculator
Tell it what you have left and how many darts are in your hand. It lists every double-out finish, picks a sensible route, explains each dart, and suggests a setup shot when there is no checkout this visit.
Last updated:
Checkouts exist from 2 to 170.
How to use the Darts Checkout Calculator
- Enter the score you have left, for example 121.
- Choose how many darts you have left in this visit.
- Optionally pick your favourite double or tick Avoid the bull for setup darts.
- Press Find checkout to see the recommended route as dart targets.
- Browse the table for other routes, or follow the setup shot if no finish is possible.
Double-out rules in brief
- Each game counts down from a start score such as 501 or 301, and every player throws three darts per visit.
- The final dart must land in a double (2 × the number) or the bullseye (50, which counts as a double).
- A visit that leaves 1, goes below 0, or reaches 0 without a double is a bust: the score returns to what it was before that visit.
- The outer bull (25) is a single, so it cannot finish a leg.
Key checkout numbers
| Score | A common route | Why it matters |
|---|---|---|
| 170 | T20 · T20 · Bull | Highest possible checkout |
| 167 | T20 · T19 · Bull | Highest odd-number checkout (169 is a bogey) |
| 160 | T20 · T20 · D20 | Highest finish on a ring double |
| 110 | T20 · Bull | Highest two-dart checkout |
| 100 | T20 · D20 | The classic "ton" finish |
| 50 | Bull (or 10 · D20) | Highest one-dart checkout |
| 40 | D20 | "Tops", the most-practised double |
| 32 | D16 | Halves to 16, 8, 4 and 2 after misses |
Checkout tips
- Practise a few "home" doubles until they feel automatic. D16 and D20 cover a huge share of routes.
- On odd numbers below 40, hit a single first to leave an even double: on 37, throw single 5 to leave D16.
- Count your setup before you throw. Leaving 40, 32, 36 or 24 is better than leaving an odd number.
- When you are well above 170, keep scoring on treble 20 or treble 19 and aim to land on a two-dart finish.
Frequently asked questions
What is a checkout in darts?
A checkout is the final visit that brings your score to exactly zero. In standard 501 and 301 games the last dart must hit a double (the thin outer ring) or the bullseye, which counts as double 25. Going below zero, landing on exactly 1, or reaching zero without a double is a bust.
What is the highest checkout in darts?
170 is the highest checkout: treble 20, treble 20 and the bullseye (60 + 60 + 50). With two darts the highest is 110 (treble 20 and bull), and with one dart it is 50 (the bull).
What are bogey numbers in darts?
Bogey numbers are scores of 170 or less that cannot be checked out with three darts: 159, 162, 163, 165, 166, 168 and 169. With two darts the bogey numbers below 110 are 99, 102, 103, 105, 106, 108 and 109.
Why do players prefer double 20, double 16 and double 8?
Even doubles that halve neatly give second chances. If you aim at D16 (32) and hit single 16, you are left on 16, which is D8; miss again into single 8 and you have D4. D20 is popular because many routes after treble 20 naturally leave 40.
How does the calculator choose the best route?
It lists every legal route, then ranks them by the number of darts needed first, followed by how easy the targets are: large trebles and singles before the bull, and well-placed doubles such as D20, D16 and D8 before awkward ones. Checkout charts used by players differ slightly, so several good alternatives are shown.
What should I do if there is no checkout?
Score to leave a finish for your next visit. The calculator suggests a setup that leaves a comfortable number, ideally a single-dart double like 40 or 32, without risking a bust.
