The standard racquetball court measures 20 feet wide, 40 feet long, and 20 feet high. Squash courts have shorter but wider than racquetball ones. Their dimensions are 32 feet long, 21 feet wide, and 15 feet (at the highest point). In racquetball, you can hit anywhere including the ceiling while in squash you have designated lines drawn around the highest point. Above this strip, the area is out of bound. So a racquetball court has more playable zones.
Squash rackets are narrower and longer than racquetball ones. The balls used in squash are less bouncy, so the game is fast paced and you have little time to get to it and respond.
In squash, you need to win 11 points to win a game. You win the match when you win three games. However, in racquetball you need to win 15 points to win a game and two games to win a match. If there is a tie, you have to score 11 points in the third match to win.
In squash, you can win a point on your own and also on your opponent’s serve. In racquetball, the rule is a bit strict. You can only win a point on your own serve like in the game of tennis.
You get two serves to play in racquetball while in squash you just have one. In squash, you hit the ball to serve when it is mid air. In racquetball, it is a bit different. You serve the ball after a bounce on the floor
