Rugby Sevens Rules, Explained

Rugby sevens is a condensed version of rugby union played with seven players a side instead of fifteen, on the same full-size pitch, under World Rugby’s abbreviated laws. Matches are two seven-minute halves, the scoring is the same as fifteen-a-side, and the extra space with fewer players makes it a fast, high-scoring, sprint-driven game.

Sevens has grown from an off-season novelty into an Olympic sport, and its short, explosive format makes it one of the easiest ways into rugby for new fans. Here is how the rules work and exactly where they differ from the traditional fifteen-a-side game.

Seven players, full-size pitch

The defining feature of sevens is the numbers. Each team has seven players on the field — typically three forwards and four backs — compared with fifteen in rugby union. Crucially, the pitch is the same size as a fifteen-a-side field. Squeezing fewer than half the players onto a full pitch creates enormous open space, which is why sevens is so fast and try-heavy: there are simply fewer defenders to beat.

Because space is everything, sevens rewards speed, fitness and one-on-one skill more than the set-piece power and forward battles that shape the fifteen-a-side game.

How it differs from fifteen-a-side rugby

Sevens keeps the spirit of rugby but trims and speeds up several laws.

Element	Rugby sevens	Rugby fifteens
Players per side	7	15
Match length	Two 7-minute halves (finals often 2 x 10)	Two 40-minute halves
Scrum	3 players	8 players
Conversions	Must be drop-kicked, taken quickly	Usually placed kicks
Yellow card	2 minutes in the sin bin	10 minutes
Format	Weekend tournaments	Single matches

The scoring itself is unchanged, which is the key point of continuity: a try is worth 5 points, a conversion 2, and a penalty or drop goal 3. Our explainer on how many points a try is worth in rugby applies directly to sevens.

The scrum and set pieces

Sevens still has scrums, lineouts, rucks and mauls, but they are scaled down. The scrum uses just three players per side instead of eight, so it is far less about raw shoving power and far more about getting the ball back into open play quickly. If you want the full mechanics of how a scrum is formed and contested, our guide to what a scrum is in rugby covers the set piece that sevens shrinks.

Lineouts are similarly reduced, often with just two or three players contesting the throw. The abbreviated set pieces reflect the format’s whole philosophy: minimise stoppages, maximise running.

Time, cards and tournament format

A standard sevens match is two seven-minute halves — just 14 minutes of play — with tournament finals sometimes extended to two ten-minute halves. That brevity lets organisers stage a whole tournament over a weekend, with each team playing several short, intense matches, unlike the single long fixtures of the fifteen-a-side game explained in our guide to how long a rugby match is.

Discipline is also condensed: a yellow card carries a two-minute sin-bin rather than ten, but with only seven players on the field, losing one for two minutes is a huge disadvantage.

Positions and style

With seven players, roles are less specialised than in fifteens, though sevens teams still blend forwards and backs. Understanding the fifteen-a-side positional framework in our rugby positions explained guide helps, because sevens draws players from the same pool but asks nearly all of them to run, pass, tackle and cover ground constantly.

Kicking remains a full part of the game — tactical kicks to find space and drop-kicked restarts and conversions are all legal and common — but sevens is defined by ball-in-hand attacking, breakaway tries and last-gasp defence across wide open turf.

The short version: rugby sevens is seven a side on a full-size pitch, two seven-minute halves, three-player scrums, quick drop-kicked conversions and two-minute sin bins, all under World Rugby’s abbreviated laws. Scoring matches fifteen-a-side (a try is 5 points), but the extra space makes it a faster, higher-scoring, Olympic-level sprint of a game.
