What Are Sets and Legs in Darts? (Explained)

Sports terminology can be confusing. Take tennis as a good example, to win a tennis match you accumulate points, games, and then sets, yet for a game of 501 in darts, the scoring system is based on legs and sets.

For those unfamiliar with how games work in darts, we’ll answer a common question of what are sets and legs in darts whilst showing the different formats that you can use. There are slight variations depending on the type of competition or organization/personal preferences so we’ll do a full overview below. 

What Are Legs in Darts

Basically, a leg is one single game of darts, be it 501, 301, or another format. Once that single game is complete then the player who wins is awarded that leg. Most matches though consist of a series of legs, it can be 3, 5, 7, and so on so it is totally dependent on the tournament or competition.

It’s also virtually almost always an odd number so one player can always outscore the other in legs and win the game. 

Some matches are won just by playing a pre-determined number of legs whereas others are based on a ‘best-of’ format meaning to win a best of 5 legs, a player needs to win 3.  

Legs in major tournaments are more often used to make up a set and in professional terms, sets are used mostly to decide darts contests for major tournaments and competitions. 

A leg can also be used as a one-off sudden death decider should players be on the same number of sets.

What Are Sets in Darts

So as we have seen a set in darts is made up of a number of legs, which are single games, and the leg is awarded to the winner. Sets in darts are made up of a number of legs with 3 or 5 being the most common, but it can be more and to win a set you must win the corresponding number of legs that a set has.

So if you want to win a set you must outscore your opponent in legs. So for example if a set consists of 3 legs to win it, it’s possible to win 3-2, 3-,1, or 3-0 and it follows the more legs in a set, the more you have to win in order to win the set.

Sets provide a more complex format and for this reason, they are mainly used for major competitions. This is because the game format is longer when using sets as a game decider so this format is only reserved for major competitions with large viewership and tv air time. 

In major tournaments, initial rounds will be made up of fewer sets (usually 1 set decided by the best of 3 legs), and then this will increase as the tournament advances through the rounds.

How Many Sets and Legs in Darts

There are many different variations on the number of legs that make up a set or the number of sets that decide a match and indeed these can also change during the various rounds of a competition. So, as you get further into a competition then the number of sets you have to win often increases – though this isn’t always the case.

The extremely high standards of darts at the present time means that the number of competitors and competitions are increasing, especially because TV has made the popularity of the sport surge in recent years to such an extent, that the professional circuit is straining to keep the hoards of darts fans happy.

This means demand on players is high and so numbers of legs and sets can be limited to low numbers in certain competitions to allow them to compete regularly without burning out.

For most amateur league competitions, there is typically 1 set needed to win with the set being the best of 3 legs. This means players need to win to legs in order to win the game. 

How Many Sets and Legs are in a Darts Final 

In the PDC World Championship Darts Finals, games consist of first to 3 legs per set with the game being first to 7 sets. Therefore, in order to win players need to win 21 legs of darts in total. This will of course be more because this is assuming that they win every game – In reality, you can win 2 legs but lose the set 3-2 so some finals can see players throw up to 35 legs in total.
