They run along the long side of the court.
They are only used when playing doubles, that is 2 players versus 2 players. This is to allow more court room for more players to hit the ball.
During singles, 1 vs. 1, the alleys are ignored and any balls that land in the alley are considered out.
From baseline to baseline and from alley to alley, a tennis court measures 78 feet by 36 feet. This does not include the extra area beyond the lines where the players run.
