Why is the number 20 on a dartboard placed between 1 and 5
It's no accident that the dartboard's highest number is sandwiched between two of its lowest; this layout is a calculated stroke of genius designed to punish inaccuracy and reward true skill.


Too Long; Didn't Read
TLDR: The dartboard is designed to punish inaccuracy. Placing the highest number, 20, next to low numbers, 1 and 5, means a slightly missed shot results in a very low score, rewarding skill over luck.
Punishing Inaccuracy: The Genius Behind Why the Number 20 on a Dartboard is Between 1 and 5
Ever stood at the oche, aimed for that glorious triple 20, only to have your dart stray a few millimetres and land with a thud in the 1 or 5? It’s a frustratingly common experience that can turn a game on its head. But this isn't a cruel twist of fate or a random design flaw. The placement of the 20, the highest-scoring number on the board, directly between two of the lowest-scoring numbers is a stroke of design genius. This deliberate arrangement is the very soul of modern darts, transforming it from a simple pub game into a true test of skill and precision. This post will explore the clever principle and historical context behind why the number 20 on a dartboard is placed between 1 and 5.
The Man Behind the "Clock" Layout
The standard dartboard numbering system we see today is widely credited to a Lancashire carpenter named Brian Gamlin in 1896. While concrete historical records are scarce, the story goes that Gamlin, a regular at his local pub, sought to create a board that would weed out the lucky players from the genuinely skilled. He was tired of seeing random, inaccurate throws rewarded with high scores.
His solution was to create a layout that intentionally penalized inaccuracy. Instead of arranging the numbers in sequential order, which would cluster high values together, Gamlin devised a system to spread them out. His goal was to ensure that a poorly aimed dart would have a high probability of landing in a low-scoring segment. The result was the iconic "Clock" layout that has remained the standard for over a century, a testament to its brilliant design.
A Design That Rewards Skill, Not Luck
The core principle behind Gamlin's layout is simple yet profound: to place high-value numbers adjacent to low-value numbers. The 20 is the perfect embodiment of this philosophy.
- The Target: The 20-point segment is the most valuable on the board, making its triple (60 points) the ultimate prize for a single dart.
- The Penalty: If a player’s aim is slightly off to the left or right, they don’t hit the 18 or 19. Instead, they are punished severely, scoring a meagre 1 or 5.
This high-risk, high-reward system is repeated all over the board. Look at the other high numbers:
- 19 is placed between 3 and 7.
- 18 is placed between 1 and 4.
- 17 is placed between 2 and 3.
This intelligent arrangement ensures that no single area of the board is "safe." A player cannot simply aim for a general high-scoring zone and expect a good result. To succeed, they must demonstrate consistent, pinpoint accuracy. It’s this very feature that elevates darts from a game of chance to a sport of immense skill. A player who can consistently hit the triple 20 under pressure has proven their mastery, while a novice will quickly see their score plummet with errant throws.
How the Layout Creates a Fairer, More Strategic Game
The genius of placing the 20 between 1 and 5 is that it fundamentally makes the game more competitive and strategic. It forces players to make calculated decisions with every throw. Is it worth risking a shot at the triple 20 when a miss could be so costly? Or is it wiser to aim for the 19, which also has low-scoring neighbours but is often considered a slightly "safer" alternative for many players?
This layout demands more than just good hand-eye coordination; it demands mental fortitude. It creates the dramatic tension we see in professional matches, where a single stray dart can change the outcome of a leg or even an entire championship. It ensures that the player who wins is not the luckiest, but the one with the most control, consistency, and nerve.
In conclusion, the placement of the 20 between the 1 and 5 is the cornerstone of the modern dartboard's design. It’s a deliberate and masterfully executed concept intended to punish inaccuracy and reward precision. This layout, attributed to Brian Gamlin, is the reason darts is a compelling sport that tests mental and physical skill in equal measure. So, the next time your dart lands in the 5 when you were aiming for the 20, don't curse your luck. Instead, take a moment to appreciate the century-old design that is challenging you to become a better player.
