Key Differences Between Indoor and Outdoor Soccer

Indoor soccer (futsal) and outdoor soccer are pretty much similar because both are, well…just soccer. Besides the difference in the name, there are a few things that make the two sports a little different from each other. The concept is just the same except for (mostly) the rules and equipment for each of the games. Let’s take a look at the differences;


Perhaps the major difference between futsal and outdoor soccer lies in the space where the game is played. Indoor soccer is obviously played indoors and therefore the space is much smaller compared to outdoor soccer. While outdoor soccer is played on a bigger field, mostly covered by grass or turf, indoor soccer is played on a much smaller space with a hardwood floor or sometimes flat turf and surrounded by walls.

Players and Formation

A normal soccer team consists of 11 players including the keeper. However, in indoor soccer, because of the limited space, the number of players is less ranging from 8 to 5 players depending on a team’s arrangement. Most professional indoor soccer teams consist of 6 players. The formation also differs in the fact that in indoor soccer there are two forwards, one midfielder, two on the defense and one keeper in a typical 6 player team while in outdoor soccer, there is the keeper, 4 defenders, 4 midfielders and two forwards.

Playing Gear

The playing gear for both outdoor soccer and indoor soccer only differ on the type of shoes. Both require shin guards, long socks and a pair of cleats. While outdoor soccer cleats have studs on their outsoles because they play outdoors and they require more traction on the grass or turf, indoor soccer cleats are flat because they require less traction on the field they play on. Some people advise that you can substitute your soccer cleats with normal working out trainers.


Another major difference comes in the rules as stated in in an article by L. White. For instance, while in outdoors soccer there is the offside rule; indoor soccer does not have any offside rule.

Another example is in the penalty/punishment for any fouls. In outdoor soccer, a red card or yellow card is shown to a player when he/she commits a foul. In indoor soccer, however, the same may apply but mostly they use the time out box for fouls whereby a player leave the field making his team play one player short.

Additionally, in indoor soccer slide tackle is not allowed, which is not the case for outdoor soccer. With the limited playing field and the type of ground they are playing on, there is a high probability for an injury. Whereas in outdoor soccer the slide tackle is a common technique.


Another significant difference between the two sports is that indoor soccer is much more faster and therefore requires more tact unlike outdoor soccer which is less fast. With indoor soccer, you have to think on your feet and you are not allowed to possess the ball for more than 5 seconds without making a pass or a shot unlike in outdoor soccer where you can dribble the ball for longer.


Outdoor soccer is a 90-minute game with only one half-time of 15 minutes. Whereas indoor soccer is a four quarter 60-minute game with 3 minute breaks in between the first and second, third and fourth quarters and a 15 minute break between the second and third quarters.


Indoor soccer allows for unlimited substitutions in a match for players. While outdoor soccer only allows 3 substitutions during the entire match.

The aforementioned are the key differences between indoor and outdoor but the concept of soccer is the same and a player can play both games without a hassle. Other minor differences like multi point scoring for indoor soccer and the time out box rule are mostly adopted from other sports such as ice hockey. A player can learn to play both sports in order to perfect each one of them and achieve an all-round tact. For example, since indoor soccer is faster game, a player can borrow this and apply it in outdoor soccer for better skill. Indoor soccer also requires a fast thinker. And this really helps even in the outdoor field and a player can excel in both successfully.
