Tennis Net Height - Official Rules & Measurements

A tennis net is an essential part of the sport. 

It separates both sides of the courts – and its height must be accurate for the game to be played properly.

But did you know that the height of a tennis net is not the same along its length?

Find out the official rules for tennis net height, why they are lower in the middle, the differences between singles and doubles matches net height, and how you can use the differences in elevation to your advantage.

Official Rules for tennis net height

The official tennis net height is 42 inches (106.7 cm) at the posts and 36 inches (91.4 cm) in the middle. 

These measurements are the official ones set by the International Tennis Federation (ITF), and all ATP’s and WTA’s major tournaments are obliged to follow them.

The aftermentioned measurements are valid for both singles and doubles matches – what varies in both disciplines is the net’s length, not its height – more on that below.

Tennis court caretakers must accurately measure the tennis net’s height – even a centimeter difference significantly impacts a player’s performance.

The top of the net also has a band that must not be wider than 2 inches (5 cm), and its color must be white.

To ensure that the net height in the center is accurate, a strap is anchored to the ground, pulling the net tightly and securing everything in its place.

Net height near the posts

The positioning of the posts is also crucial. An alteration in how wide the posts are positioned impacts the net’s height at different points.

Official rules dictate that the posts must be positioned 3 feet outside the court. If playing singles, 3 feet outside the singles court, and the same for doubles matches.

A singles stick can be applied to “transform” a double net height into a single one without needing to move the posts. 

It has the same height as the post – 42 inches (106.7cm) and is positioned where the singles posts would be.

This ensures that the net’s height is the same as a singles net – otherwise, it would be lower in some spots.

Net height in the center of the court

The net’s height in the middle of the court is always the same, independent of playing singles or doubles – 36 inches (91.4 cm).

Why are tennis nets lower in the middle?

Tennis nets are lower in the center of the court for two main reasons:

  • Gravity – tennis nets are heavy, and gravity pushes them down. The best tennis nets ensure that when a ball hits the headband it drops near the net, instead of bouncing of it.They can’t be made of soft material, otherwise, they would flap when hit by a ball at hundreds of km/h.  But it could be “more or less” straight if they wanted it to. This brings us to the next point.
  • Strategy – In the end, the main reason tennis nets are lower in the center than on the posts boils down to a strategic advantage. Players must be more careful when playing a shot down the line because the net is higher at the point where the ball will pass to the other side of the court. Conversely, playing the ball down the middle will be easier because the net is lower. This adds a layer of complexity to the game. 

How net's height affects tennis strategy

Down the middle / Cross court

Tennis players have an advantage playing a cross-court shot (also called down the middle) because the net is at its lowest point from the ground and because the distance the ball has to travel to hit outside the court is much greater than when shooting a parallel shot.

This allows players to be more reckless when playing down the middle – hitting it harder and lower, making it more difficult for the opponent to return the shot.

Down the line / Parallel shots

The game would be much easier if the net were all at the same height. If a player is on the other side of the court, send the ball down the line to score the point.

Instead, a parallel shot is somewhat dangerous for a player to execute correctly because of the line height. 

This obliges the hitting player to hit the ball higher, giving more time to their opponent to return it.


When serving, the net’s height also has an influence. 

A serve to the court’s side is, strategically speaking, more effective. The player returning the ball will be at the side of the court, leaving the other side open for a parallel shot to finish the point. 

However, the net’s being higher on the sides than on the middle is also more challenging to execute and more prone to errors. 

On the flip side, since the net is at its lowest point in the center, a serve to the T lines will typically be faster because the ball can travel downwards.
