Difference Between Five-a-Side and Futsal
Although frequently used interchangeably, five-a-side and futsal are technically different sports. Futsal is a FIFA-regulated discipline played with boundary lines (not boards), a smaller heavier ball, and specific rules.
Five-a-side is a broader term covering any small-sided game on artificial turf or carpet. Rules vary widely by local custom; an official futsal tournament and a friendly kickabout among friends may have completely different rules.
Core Rules
• Player count: 5v5 (including GK) in standard futsal; variations like 6v6, 7v7 are common in informal five-a-side.
• Goalkeeper hands: In futsal the keeper may only handle the ball inside the penalty area.
• Back-pass rule: A deliberate back-pass to the goalkeeper cannot be handled; if it is, a free kick is awarded to the opposition.
• Time-outs: In futsal each team may call one 1-minute time-out per half.
• Foul accumulation: In futsal, after 5 team fouls per half, all subsequent fouls result in a direct free kick from the penalty spot — no wall allowed.
Yellow and Red Cards
A yellow card is a caution, not an expulsion. Two yellows equal a red card and dismissal. A red-carded player may be replaced after a set period (futsal); house rules in informal five-a-side may vary.
Substitutions
One of futsal's most distinctive rules: substitutions are made on the fly ('flying substitution') while play continues. The outgoing player must cross the halfway line before the replacement enters.
This rule is not commonly applied in informal five-a-side; teams typically agree on their own substitution process.
Ball Out of Play
In futsal, when the ball crosses the touchline a kick-in replaces the throw-in. In backyard five-a-side, many groups use a simple free kick or just play the ball back in however is most convenient.
