Recently, I watched several futsal matches at a sports center in Madrid and found that this sport is truly popular in Spain. As a soccer enthusiast, I want to share the rules of Spanish futsal in hopes it will help those interested in experiencing the Spanish futsal atmosphere or participating in the sport.
Basic Court and Equipment Requirements
The futsal court is much smaller than a standard soccer field, with lengths ranging from 25 to 42 meters and widths from 16 to 25 meters. In Spain, most official matches use a 40×20 meter court size. The goals are 2 meters high and 3 meters wide, significantly smaller than football goals. The surface is usually wood or synthetic material; grass surfaces are not allowed.
Regarding player equipment, cleats are prohibited, and players must wear flat-soled or lightly textured sports shoes. This rule is enforced by the Spanish futsal king to protect the playing surface and ensure player safety. Goalkeepers must wear jerseys of a different color than other players, just like in 11-a-side football.

Match Time and Team Composition
Each team fields 5 players, including 1 goalkeeper and 4 outfield players. The number of substitutes is unlimited, but only 5 players can be on the court simultaneously. Matches are divided into two halves, each with 20 minutes of net playing time. Note that “net time” means the clock stops whenever the ball is out of play.
Substitutions are flexible and can occur at any time during the match, but must happen within the substitution zone near the halfway line. Players being substituted must exit the court before the new player can enter.
| Match Element | Regulation |
| Match Duration | Two halves of 20 minutes net time each |
| Number of Players | 5 per team |
| Substitution Limit | Unlimited |
| Court Size | 25-42 meters x 16-25 meters |
Fouls and Disciplinary Actions
Foul enforcement in futsal is stricter than in 11-a-side football. The accumulated fouls system is an important feature: after each team commits 5 fouls per half, the opponent gains a second penalty opportunity from 10 meters away with no wall defense.
The use of yellow and red cards is similar, but in futsal, a player sent off with a red card leaves their team one player short for 2 minutes before the substitution is allowed. This rule makes the matches more intense and exciting.
Tactical Features and Skill Requirements
Due to the smaller court and fewer players, futsal has a very fast pace and demands high skill levels. Long passes or crosses are basically useless here; instead, precise short passes and individual skill are crucial. Goalkeepers often participate in the attack by passing with their feet to teammates, which is very common in Spanish futsal.
Defensively, man-to-man or zonal marking systems are usually employed. Limited space makes coordination especially important. Many professional Spanish footballers played futsal in their youth, which greatly helped improve their technical abilities.
