A tennis net can look level from the baseline and still be several inches too high or low at the center. That small difference changes how the ball clears the net, so it is worth setting the net carefully before you play. The basic job is straightforward: position the supports, tension the net, then check the height at both the posts and the middle.
What You’ll Need
- A tennis net and its cable or top cord
- Two net posts, or a portable net frame
- A center strap and ground anchor or hook
- A tape measure or net-height measuring stick
- A post crank or tensioning handle, if your system uses one
On a permanent court, the post sleeves are usually already installed. A portable net may have a frame that assembles in sections, so check its instructions before setting it up; portable systems vary, and some are designed for smaller courts rather than regulation play.
Know the Regulation Heights and Positions
On a standard court, the net should measure 3 feet high at the center and 3 feet 6 inches high at the posts. The center strap pulls the net down to the lower height, while the posts hold the ends higher. Measure from the court surface directly beneath the net—not from a nearby line or a raised post base.
For doubles, the net posts sit 3 feet outside the doubles sidelines. For singles, use singles sticks placed 3 feet outside the singles sidelines when the court has a doubles-width net. The sticks support the net at the proper singles position; they are not a substitute for adjusting the center strap.
How to Set Up a Tennis Net
-
Check the court and equipment.
Clear leaves, balls, and other debris from the post bases and the area where the center anchor will go. Look over the net for torn mesh, a frayed cable, or a damaged crank. If you are using a portable frame, lay out the parts and confirm that the feet or anchors are stable and suited to the surface.
-
Position the posts.
For a permanent court, make sure each post is seated securely in its sleeve. For a portable system, place the supports at the correct width and assemble the frame according to its instructions. Keep both posts in line with the center of the court. A net set at an angle can make the court harder to judge and may interfere with play.
-
Attach the net cable or top cord.
Connect the cable ends to the post hooks, eyelets, or tensioning mechanism. The net’s white top band should face upward and run evenly between the posts. If one end is twisted, straighten it before tightening; otherwise, the net may sag unevenly or bunch along the top.
-
Tension the net gradually.
Use the post crank or tensioner to take up slack until the net is firm and the top band is reasonably straight. Tighten in small turns and check the net as you go. The goal is a stable net, not a cable pulled as hard as possible. Excessive tension can strain the cable, posts, or fittings, and can make the system difficult to release later.
-
Set the center strap.
Find the center point between the posts and attach the strap to the net’s top band. Run it straight down to its ground anchor, then adjust it until the net measures 3 feet high at the center. On courts with a fixed anchor, make sure the strap is attached securely and is not twisted.
-
Measure the height at the posts.
Check that the top of the net is 3 feet 6 inches above the court surface at each post. If one side is low, check the cable attachment and post position before adding more tension. The center strap controls the middle height; the post supports and cable control the ends.
-
Make a final alignment check.
Stand behind each baseline and look along the top band. It should appear level from post to post, with the expected dip at the center. Confirm that the net is centered across the court and that the bottom edge is not dragging or folded under.
Setting Up Singles Sticks
If you are playing singles on a court with a doubles net, place one singles stick on each side, 3 feet outside the singles sideline. The sticks lift the net to 3 feet 6 inches at those points. The center strap should still hold the middle at 3 feet.
Set each stick upright beneath the net and make sure it is stable. Keep it clear of the singles sideline rather than placing it directly on the line. After positioning both sticks, check their height and confirm that the net is not caught or bunched against either one.
Common Setup Mistakes
- Guessing the center height: A net can look correct and still be off. Use a measuring stick or tape, especially if several people use the court.
- Over-tightening the cable: More tension is not a substitute for correct measurements. Tighten only enough to support the net firmly.
- Forgetting the center strap: Without it, the middle may sit too high, changing the ball’s clearance over the net.
- Using the wrong supports for singles: Singles sticks belong outside the singles sidelines. Check their placement before a match.
- Leaving a portable frame unstable: Set its feet flat and secure any anchors supplied with the system. A net that shifts during play is both distracting and unsafe.
Temperature and weather can affect a net’s tension. A cable may feel different after a cold night or a hot afternoon, and wind can push a loose net around. If the center measurement changes, readjust the strap and recheck the ends rather than assuming the original setup will stay perfect all day.
Frequently Asked Questions
How high should a tennis net be in the middle?
The center of a standard tennis net should be 3 feet above the court surface. Use the center strap to bring it to that height, then measure rather than relying on appearance.
How high should the net be at the posts?
The net should be 3 feet 6 inches high at the posts. Measure vertically from the court surface beside each post to the top of the net band.
Do I need singles sticks for a singles match?
Use singles sticks when playing singles with a doubles-width net. Place them 3 feet outside the singles sidelines and check that the net is 3 feet 6 inches high at each stick.
How tight should the net be?
Tight enough to stay supported and form a straight top band, but not so tight that the cable, posts, or fittings are under unnecessary strain. Set the height with the strap and supports, then make only small tension adjustments.
Final Thoughts
For a dependable setup, position the supports correctly, tension the net without forcing it, and measure both the 3-foot center height and the 3-foot-6-inch height at the posts. Add singles sticks when needed, and give the net a quick check before play. Those few minutes make the court fairer and keep the equipment in better shape.
