Under 5.5 in Darts — Full Explanation
In darts betting, Under 5.5 usually refers to a totals market, often labeled “Total Legs” or “Total Sets” depending on the tournament and bookmaker.
Meaning of Under 5.5
You are betting that the total number of legs or sets in the match will be 5 or fewer.
- If the match ends with 5 or fewer legs/sets → Your bet WINS
- If the match ends with 6 or more legs/sets → Your bet LOSES
This market is common in:
- Short-format matches (best of 7 legs, best of 5 sets, etc.)
- First rounds of competitions like Premier League, World Series events, European Tour qualifiers
When “Under 5.5 Legs” Applies
This often applies in Best of 7 legs matches.
Best of 7 Legs = First to 4 legs wins
The total legs can end:
- Minimum: 4 legs (4–0)
- Maximum: 7 legs (4–3)
So an Under 5.5 bet wins if the match ends:
- 4–0 (4 legs)
- 4–1 (5 legs)
It loses if the match ends:
- 4–2 (6 legs)
- 4–3 (7 legs)
Example With Realistic Teams/Players
Let’s use two popular darts players:
Example Match:
Michael van Gerwen (MVG) vs Luke Humphries
Format: Best of 7 Legs (First to 4)
Scenario A – Under 5.5 wins
- MVG wins 4–0 → Total legs = 4
- Humphries wins 4–1 → Total legs = 5
Your Under 5.5 bet wins.
Why?
Because the match ended before it reached leg 6.
Scenario B – Under 5.5 loses
- MVG wins 4–2 → Total legs = 6
- Humphries wins 4–3 → Total legs = 7
Your Under 5.5 bet loses.
Another Example Using a Weaker vs Stronger Player
Example Match:
Gerwyn Price vs Local Qualifier
If Price is far stronger, he may win:
- 4–0, or
- 4–1
These outcomes create 4 or 5 total legs.
This is a perfect match to consider Under 5.5.
Why This Bet is Popular
Because in darts:
- Strong players often dominate weaker opponents.
- Short-format matches finish quickly.
- Early rounds usually produce one-sided scores.
BETTING TIPS for Under 5.5 in Darts
Look for mismatches
If one player is far stronger:
- High averages (100+)
- Better checkout %
- More experience
They can win quickly.
Example mismatches:
- Top-10 player vs qualifier
- Premier League star vs new entrant
Avoid evenly matched games
Players like:
- Smith vs Wright
- Clayton vs Aspinall
- Cross vs Humphries
These tend to go long, like 4–3 or 4–2, which kills an under bet.
Check the tournament format
Not all darts matches are:
- Best of 7
- Best of 5 sets
- Short format
Some are Best of 11 legs (first to 6) → DO NOT play Under 5.5 here.
Always confirm the format.
Study recent performances
Look at:
- Last 5 match scores
- Tactical form (averages, doubles hit rate)
If a player has been losing heavily or winning easily, it affects totals.
Use the In-play advantage
Watch the momentum:
- If a player starts dominating 2–0 early
- They may finish the match quickly
→ Good for Under 5.5
If it’s 2–2 early → Avoid.
