A regulation tennis net is 3 feet high (0.914 metres) at the center and 3 feet 6 inches high (1.07 metres) at the posts. The middle is lower because a center strap pulls the net down; the top edge should not sit level from post to post.
Measuring the net correctly matters for fair play and for a court that feels right. A net that is too high can turn a routine rally ball into a tough clearance, while one that sags too much makes it easier to hit aggressive shots. Here’s how to check the height and what to look for during setup.
Official tennis net height measurements
Under the standard tennis rules, measure from the court surface to the top edge of the net. The center measurement is taken where the center strap holds the net down. The posts are higher to keep the net supported near the sidelines.
| Where to measure | Regulation height | Metric equivalent |
|---|---|---|
| Center of the net | 3 feet (36 inches) | 0.914 metres |
| Net posts | 3 feet 6 inches (42 inches) | 1.07 metres |
| Singles sticks, when used | 3 feet 6 inches (42 inches) | 1.07 metres |
For a singles match played with a doubles net, singles sticks support the net at the correct height near the singles sidelines. They are placed 3 feet outside each singles sideline. The center of the net still needs to measure 3 feet high.
How to measure tennis net height
A tape measure is enough for a quick check, though a net-measuring stick makes regular court checks faster. Measure vertically from the playing surface—not from the bottom of the net, a loose strap, or the ground beyond the court—to the top edge.
- Check the court surface. Choose a spot on the actual playing surface, directly below the point you’re measuring. On an outdoor court, make sure you are not using a raised edge or a patch of loose material as your starting point.
- Measure at the center. Find the midpoint between the net posts. At that point, the top of the net should be 36 inches above the court. The center strap should be snug enough to hold it there.
- Check the posts. Measure from the court surface to the top of each net post. Each should be 42 inches high. The net should be supported by the proper posts or, for singles play with a doubles net, singles sticks.
- Recheck after adjusting. Tightening a cable or strap can change the center height. Measure again once the net is set and secured.
For the most reliable reading, keep the tape measure straight up and down. If you’re using a long tape, have someone help hold it steady. A marked measuring stick can be easier to use because it helps prevent a tilted measurement.
Why the net is lower in the middle
The net’s shape affects the shots players choose. At the center, where the net is lower, a player has more room to hit a ball over it than near the sidelines. This is one reason crosscourt groundstrokes can be a dependable choice: the ball travels over the lower middle section and has more court length to land in.
The higher net near the posts makes sharp angles harder to play safely. A player aiming close to the sideline has to clear more net and keep the ball inside the line. Even a small difference in net height can change the feel of those shots, especially on a fast, flat drive.
Net height also matters at the start of play. A serve that clips the net and lands in the correct service box is treated according to the rules for a let; it isn’t made legal or illegal by changing the net height. But a net set too high or too low changes the conditions for every serve and rally that follows.
Common measurement mistakes
- Measuring to the bottom of the net: The official height is measured to the top edge.
- Forgetting the center strap: The middle should be held at 3 feet, not left to sag freely.
- Assuming the whole net is 3 feet high: The posts are 3 feet 6 inches high.
- Measuring from outside the court: The court surface directly beneath the net is the reference point.
- Checking only once: A net can shift after tension adjustments or use, so check the center again before play.
If the net height seems different from one side to the other, check that the posts are stable and the court is level. On a court with an uneven surface, a single measurement may not describe the whole setup. For a match, follow the facility’s procedures and use a proper measuring tool rather than relying on appearance.
Frequently Asked Questions
Is a tennis net 3 feet high everywhere?
No. It is 3 feet high at the center and 3 feet 6 inches high at the posts. The center strap holds the middle at the lower measurement.
Do you measure tennis net height from the court or the ground?
Measure from the playing surface directly below the net to its top edge. On a hard court, that means the court surface; on a grass or clay court, use the surface the players are standing on.
How high are singles sticks?
Singles sticks are 3 feet 6 inches high. When a doubles net is used for singles, place one 3 feet outside each singles sideline to support the net at the proper height.
How often should a tennis net be checked?
Check it before play, especially if the net has been adjusted, moved, or used heavily. For a casual game, a quick center measurement is a practical check; organized play may require the facility or officials to inspect it.
Final Thoughts
For a regulation setup, remember the two key numbers: 3 feet at the center and 3 feet 6 inches at the posts. Measure vertically from the court to the top of the net, and make sure the center strap is holding the middle at the right height. A quick check before play helps keep the court fair and the ball’s bounce and clearance consistent.
