Tennis Court Dimensions – How Big Is A Tennis Court

What are the dimensions of a tennis court in feet? Are all tennis courts the same size?

This post was inspired by a question I received via the contact form which asked me about the size of a tennis court. I've written a lot about tennis courts in the past but only ever about court speed, court pace index, and the different court surfaces used but never about the dimensions.

The reader was new to tennis and the camera angle on TV made them think that different tournaments had different size courts. This is obviously not the case because virtually every tennis court across the globe is the same size.

There are obviously some exceptions to the rule where individuals have put in smaller courts for recreational use or for ‘Touch Tennis' but all ATP and ITF courts are a standard size. But what are the exact dimensions of a tennis court? Let's take a look.

Regulation Tennis Court Dimensions

Key Tennis Court Dimensions

  • Overall Length: 78 ft / 23.77 m
  • Overall Width: 27 ft / 8.23 m (Singles), 36 ft / 10.97 m (Doubles)
  • Overall Surface Area: 2,106 sq ft / 195.7 sq m (Singles), 2,808 sq ft / 260.9 sq m (Doubles)

Areas of the Tennis Court

  • Length of Service Box: 21 ft / 6.4 m
  • Width of Service Box: 13.5 ft / 4.1m
  • Area of Each Service Box: 283.5 sq ft / 26.3 sq m
  • Backcourt (No Man's Land): 18 ft / 5.5 m x 27 ft / 8.2 m (486 sq ft / 45.2 sq m)
  • Doubles Alley: 39 ft / 11.9 m x 4.5 ft / 1.4 m (175.5 sq ft / 16.3 sq m)
  • Net: 3ft / 0.9m high in the centre, 3.5ft / 1.1 m high at the net posts
  • Center Line: 4″ / 0.1 m long

Traditionally court size is given in the imperial measurement of feet. I've added in metres for those who prefer metric rounded to one decimal point.

What About The Size of the Overall Playing Surface?

At every level of tennis, as well as the tennis court marked with the lines, the playing surface needs a run-off area. At club level this is so you don't run into a fence and for tournament play at ATP & ITF level space is needed for an umpire, line judges and ball boys. Because of this, the ITF does specify the minimum dimensions of a court.

The recommendations include the area behind the baseline and the sides of the court where the umpire plus various other bits of equipment sit.

The size of the area varies from tennis club to tennis club and from tournament to tournament. At the Grand Slams, the main show courts tend to be fairly similar in size at all four slams, although the outside courts can vary depending on the venue, Wimbledon's outside courts, for example, are fairly small in overall area.

The difference in size variance increases on the ATP tour due to the fact there are so many tournaments, some have purpose-built venues whilst others are shoehorned into existing facilities. The area behind the baseline is typically larger on clay courts due to the nature of the surface and players standing far behind the baseline.

In some cases, outdoor tournaments will store their tarpaulin covers at the back of the court, which David Goffin knows all too well as he badly twisted his ankle at the French Open on the covers when he tripped whilst sliding.

Recommended Overall Court Playing Surface Dimensions

The image and table below shows the minimum and recommended dimensions of an entire court area at an international and recreational level. The minimum is the first figure and the figure in parenthesis is the recommended one.

Does Overhead Space For Indoor Courts Matter?

Tennis Court Overhead Space

For indoor facilities at the tournament level, the minimum overhead clearance should be 40 feet above the height of the net. You can see the ITF recommendations in the table below:

Other Common Questions

Are all tennis courts the same size?

Yes, all tournament courts and any registered tennis club courts are the same size. The only difference in size is the areas around the marked court which differs from venue to venue with some having more space to play with than others. As mentioned there are exceptions to the rule with junior courts often being smaller but scaled down in proportion to full-size measurements. Some individuals may lay smaller courts too for more recreational play

What about tennis court markings? Are they a set size?

The white line markings that mark the areas of the court also have standard thicknesses. The centre service line and centre mark should be 2 inches (5 cm) wide. The other lines of the court must be between 1 inch (2.5 cm) and 2 inches (5 cm) wide, except the baseline that may be up to 4 inches (10 cm) wide.

Huge fan of Roger Federer. I watch all his matches from Grand Slam level right down to ATP 250. When I'm not watching or tweeting about tennis I play regularly myself and use this blog to share my thoughts on Federer and tennis in general.

  1. Thanks. I can see why someone questions the size of different courts on the tour. I believe Paris is the worst for distortion?
    For watch-ability, the colour of the court makes a difference too. If you look back at old footage of say the AO, the all green court is hard on the eyes. I like the blue and the grey for LA is nice too.
    Hope everyone is well! Lots of snow here. Scored tickets to Sir Paul…woohoo.

    1. I’d never even thought about it tbh until someone asked. Paris is always a weird angle. Challenger streams are often weird angles too.

      Macca? He’s past it and can no longer sing. Don’t waste your cash!

      1. Too late. I’ll waste my cash for the experience. And soon I’ll be wasting my cash watching Nadal and Djokovic play. But in the sun and warmth. Could use some of that about now.

  2. The impression of the court size depends on:
    1) The horizontal distance of the camera to the court
    2) The height at which the camera is fixed
    3) The “look-down” angle (this is strongly dependent on the choice of 1) or 2), so it’s not really a variable).
    4) The focal length of the camera lens (also known as “zoom”…)
    There.

    1. Thanks, for the speed you can just search the site or use the links in the opening paragraph, I’ve covered them all many times. As of right now, I don’t see much else to go at? Maybe more on the surface composition I can do at a later date.

  3. Hi Jon, I presume these measurements already include the thickness of the lines? You said “The other lines of the court must be between 1 inch (2.5 cm) and 2 inches (5 cm) wide, except the baseline that may be up to 4 inches (10 cm) wide.” Does that mean the outside lines actually do not have a standard thickness?

    When I watch the pros play the court seems so big. When I do, the ball would go out so easily when I don’t even hit it hard ?

    1. Yes, the measurement is to the outside edge of the line. So the court is 78 feet long from one baseline to the other.

      The baseline is thicker to help with line calling I think. I guess it also helps on TV for viewers seeing the baseline in the distance.

  4. Good to know properly even for an armchair fan (I used to play, though). Surprised that the sidelines could be different… I wonder if David Goffin got some compensations. Poor guy.
    Thanks for the education anyway, Jonathan.

  5. The dimensions of the court outside the actual ball playing area matters a lot to few players. I remember Rafa complaining that the size of the court being not big in enough on the Central Court of Rome Masters was one of reasons for his loss to Thiem 2 years back ? May be wanted to reach the balls that were going to spectators ?

    1. Google is your friend Muser.

      She wrote an article about transgender in sport:

      “To put the argument at its most basic: a man can decide to be female, take hormones if required by whatever sporting organisation is concerned, win everything in sight and perhaps earn a small fortune, and then reverse his decision and go back to making babies if he so desires.”

      The whole thing is a farce. Anyone with half a brain knows she is correct. Only weird libtards or those scared of being accused of hate crimes seem to disagree. It’s worrying how fashionable being transgender has become.

      Have you seen Hannah Mouncey playing handball? 😆

      1. Yes, I tried google. Thought perhaps this was the hint. Seems an unfair praxis, yes. A case for throughly investigation by competent scientists.

      2. Why waste money with a scientific investigation that will only prove what biology since the dawn of man kind has shown us?

        A man who decides to be a woman and compete in sport is going to wipe the floor with females. There was a weight lifting one last week setting records galore.

        You’re going to get people transitioning now purely on the basis you can make money doing it ?

        It’s not a controversial stance from her, just media and all the usual idiots acting offended.

      3. Easy answering. Sometimes people are born as girls, and other think they are men, and will take their results away. In such cases those accusations ought to be proved.

  6. Also,just come back from Madrid from a city break.More Art than tennis.But quite a few adverts for the Madrid tournament.I have never seen a clay court tournament.Apart from RG can anybody recommend a clay court tournament.?
