Swimming stroke rules
The technical rules that define how each competitive swimming stroke must be performed and how walls are touched.
Overview
Each competitive stroke has its own legal form. Backstroke is swum on the back, breaststroke requires simultaneous arm and leg movements with a two-hand wall touch, and butterfly needs a symmetrical arm recovery over the water, while freestyle allows any style.
Turns and finishes are also governed: for example, breaststroke and butterfly require both hands to touch the wall together. Swimming a stroke illegally, or an incorrect turn or finish, leads to disqualification.
Key points
- Backstroke is swum on the back for most of the race.
- Breaststroke and butterfly require a two-hand touch at the wall.
- Freestyle allows any stroke the swimmer chooses.
- An illegal stroke, turn or finish leads to disqualification.

Officiating
- JudgeA judge is an official who scores performance in judged sports, awarding marks for execution and difficulty rather than counting goals or timing a race.
- Start and Stop SignalsThe whistle, gun, bell or hooter an official uses to begin and end play or a race, plus the rules that keep starts clean and penalise false starts.
- RefereeThe primary on-field official who enforces the rules, controls play, penalises fouls, awards restarts, and blows the whistle to start and stop a match.
- Out-of-Bounds CallAn official's ruling that the ball or a player in possession has left the legal playing area, stopping play and handing a restart or possession to the opponent.
Disciplines
- FreestyleFreestyle is the fastest swimming stroke, swum face-down with an alternating arm pull and flutter kick — the stroke most people picture when they think of swimming.
- BackstrokeBackstroke is swum face-up with an alternating arm pull and flutter kick — the one competitive stroke where you breathe freely because your face stays out of the water.
- BreaststrokeBreaststroke uses a simultaneous, symmetric arm sweep and a whip-like frog kick, with a distinct glide between strokes — technical, rhythmic and the slowest of the four strokes.
- ButterflyButterfly is swum with a simultaneous over-water arm recovery and an undulating dolphin kick — the most physically demanding stroke, built on rhythm and core-driven body movement.
- Individual medleyThe individual medley (IM) combines all four strokes in a set order — butterfly, backstroke, breaststroke, then freestyle — testing all-round swimming across a single event.
