Standard Dimensions of a Dartboard and Guidelines (with Drawing)

Dartboard Dimensions

The contemporary game of darts can be traced back to the French. The game eventually found its way to the United Kingdom via a funfair, where people could gamble on their ability to throw multiple darts as accurately as possible at a wooden target.

The modern dartboard consists of multiple segments with assigned numerical values. The objective is to score below or over a certain number. Missing the board completely or causing the dart to bounce off of the board would result in a score of zero.

Today, there are multiple types of dartboards with numerous sets of rules. However, as a competitive sport, the Darts Regulation Authority (DRA), a non-profit organization that ensures good governance and integrity in darts, has set a standard size and ruleset to govern how the game is played on the international stage.

If you don’t have all day to sit around and read about the dimensions of a dartboard, allow me to give you a quick summary.

According to the DRA, a bristle dartboard must measure precisely 17.76 inches (451 millimeters) in diameter.

There are at least ten dartboard varieties to choose from. The most commonly used dartboard for competitive play is known as the Old London Dartboard or Clock Dartboard. You can instantly recognize it by the treble and double rings, as well as the double-bullseye market at the center.

While dartboards vary in numbering styles and appearance, they all follow the same size standards set by the DRA. Every dartboard used for competitive play must measure 17.76 inches (451 millimeters) across and 1.5 inches (38.1 millimeters) in depth.

Even though some organizers may promote their games as using 18-inch-wide (457 millimeters), they still use the same precise dartboard standards set by the DRA.

Dartboard Segment Dimensions

The typical dartboard used in competitions is separated into 20 different segments as denoted by the numbers just outside of the outer-most ring, known as the double ring. The distance from the center of the dartboard to the outside of the double ring is 6.69 inches (170 millimeters).

As for the triple ring—the ring between the double ring and the center—it measures 4.21 inches (107 millimeters) from the center of the dartboard. The widths of the double and triple rings are 0.315 inches (8 millimeters).

At the center are two circles of different colors. The larger circle measures 1.26 inches (32 millimeters) in diameter, and the smaller center, known as the bull, measures 0.5 inches (12.7 millimeters) across.

When setting up a dartboard for competitive play, the organizer must ensure that the number 20 is at the top of the board. The dartboard should be securely fastened to the wall so as to prevent it from moving as darts hit the board and players remove their darts from the board.

The bull must be exactly 5 feet 8.11 inches (1.73 meters) from the ground. The player’s frontmost toe must be exactly 7 feet 9.31 inches (2.37 meters) away from the dartboard before throwing their darts.

FAQ About Dartboards
FAQ About Dartboards

1. How do you play darts?

There are several varieties of dart games you can play, but for competitive play, people usually stick to 501 darts. You can check out the detailed guide to play 501 darts here, but essentially, the goal of the game is to reach a score of zero. One round consists of throwing three darts.

Each player or team starts with a score of 501. To begin subtracting points from their score, they must land a double-in, which means they have to land a dart in one of the double-ring sections. The highest score you can get per turn is 180, where the player hits the triple 20 scores.

During the final stages of the game, if a player “busts”—i.e., they score beyond 501—their score is returned to the original number at the start of the round. Please note that players don’t have to use all three darts during the final round.

2. How heavy are the darts?

The weight of a standard steel-tip dart ranges from 18 to 50 grams (0.63 to 1.76 ounces). As for soft-tip darts for competitive play, players typically use 16-, 18-, or 20-gram (0.56-, 0.63-, or 0.71-ounce) darts.

3. Are lighter darts better than heavier darts?

On average, professional dart players use steel-tip darts that weigh 22 grams, though Phil Taylor, one of the world’s best professional darts players, uses 26-gram darts for competitive play.

Heavier darts throw straighter, whereas lighter darts may have a parabolic curve when players release them. If you’re thinking of getting into darts, try using darts of different weights to see which of them feels the most comfortable in your hands.

4. Can players lean over the throw line?

Yes, players are free to lean their upper bodies past the throw line, as long as their toe does not step over the throw line while maintaining balance. However, a darts player is not allowed to lunge forward while throwing the darts.

5. Is playing darts dangerous?

It can be if the players do not exercise caution while throwing and retrieving their darts. This is especially true for steel-tip darts since the steel can easily penetrate the skin. If someone as soft as a Nerf gun dart can cause serious eye injury, a steel or soft-tipped dart can certain be dangerous in the wrong hands.

Conclusion
