Darts Total Legs Betting: Over/Under Hit Rates by Match Format

Total legs is the market I come back to most in darts, because the line looks simple and the price often isn't. The question here is plain: how long do professional matches actually last, and how often do the usual over/under lines land? For live selections, head to today's darts tips. This study is the groundwork behind them.

The headline answer is that the common half-point lines sit very close to a coin flip but tilt towards the under. A first-to-6 match averages 9.17 legs, and over 9.5 legs lands in 45.9% of them. The first-to-10 line at 16.5 behaves the same way at 47.9%. That tilt gets sharper when one player is a strong favourite.

1Most first-to-6 matches run to 9, 10 or 11 legs

This is the shape of 2,343 first-to-6 matches, best of 11 legs. Whitewashes are rare: only 4.2% finished 6-0. The single most common result was 10 legs, a 6-4, in 24.2% of matches. A full 11-leg decider came up in 21.7%.

That spread matters because the 9.5 line splits the busiest part of the distribution. A 6-3 and a 6-4 sit either side of it, and both are common outcomes. One broken throw in the middle of a match is often the whole bet.

What I take from this is that a deciding leg is a regular outcome rather than a freak one. More than a fifth of these matches went the distance. But the 6-3 and 6-4 scorelines still do most of the work, and the 9.5 line falls right between them.

2Standard total-legs lines lean slightly towards the under

Here are the hit rates and fair odds for every format, with no bookmaker margin. In first-to-6 matches, over 8.5 legs landed 69.1% of the time, which is a fair price of 1.45. The 9.5 line drops to 45.9%, so a fair over is 2.18 and a fair under is 1.85. Over 10.5 needs a decider and landed 21.7%, which is 4.60 fair.

The longer formats tell the same story. First-to-10 matches averaged 16.09 legs and went over 16.5 in 47.9% of 1,037 matches. First-to-5 went over 7.5 in 46.5%, and first-to-11 went over 18.5 in 44.8% of 143 matches.

The caveat that matters most sits here. The records are missing two World Championship editions, and the first-to-5 and first-to-11 samples are smaller and drawn from fewer events. So I trust the first-to-6 and first-to-10 rows far more than the outer two.

3Strong favourites drag matches below the overs line

To test whether mismatches shorten games, I split matches from 2016 onward by the favourite's pre-match win expectation. That expectation comes from a simple Elo model built only from these televised-major results, so treat it as an illustrative rating rather than a market price. In first-to-6 matches, over 9.5 legs landed 45.3% of the time with a favourite under 60%, and 43.7% with an 80%+ favourite.

The effect is much clearer over the longer distance. In first-to-10 matches, over 16.5 legs hit 52.1% when the favourite was under 60%. That fell to 43.6% when the favourite was rated 80%+.

The first-to-6 bands barely move, with the middle bands a touch higher than either end. The first-to-10 line, though, slides steadily as the favourite gets stronger. More legs give the better player more room to pull away, and that is where the edge shows itself.

4First-to-6 match length has barely moved since 2015

Darts has got deeper and the scoring has got heavier, so I wanted to see whether matches have become longer or shorter. The average first-to-6 match lasted 9.1 legs in 2015 and 9.4 legs in 2026. Every year in between stays inside that narrow band.

That stability is useful. A line set around 9.5 is not chasing a moving target, so these historical hit rates hold up reasonably well as a baseline. The later years tick up slightly, which is something I keep an eye on, but it isn't a trend I'd lean on yet.
