When a point or serve gets replayed.

Quick answer & tips ▾

On a serve, a let happens when the ball clips the net and still lands in the correct service box. That serve is simply replayed with no penalty, and there is no limit on how many lets you can serve. If the ball clips the net and lands outside the box, it is a normal fault.

A let can also be called when something interrupts play, like a ball rolling onto the court. In that case the whole point is replayed, starting again from the first serve. During a rally, a ball that clips the net and goes over is live, so play on. Some formats, including US college tennis, use no-let serving, where a serve that clips the net and lands in is in play.

Key tips

Net cord on a serve that lands in: replay that serve.
Net cord on a serve that lands out: fault.
Net cord during a rally: keep playing.
Call interference lets right away, not after the point ends.
