Most courts are open from 8:00 a.m. to dusk, except at Central Park where courts open at 7:00 a.m. and Randall's Island where courts open at 7:00 a.m. and close at 7:00 p.m.

The first thing to consider when looking at tennis racquets is the frame. You have many options when it comes to size, shape, material, and so on. A racquet with a larger head will help you make more powerful swings, whereas a smaller head affords you more control. Can’t decide? A mid-sized head offers a little of both! For length, a longer racquet can offer better leverage per swing for more power, but a traditional-length racquet provides a better balance of power and control. When considering the weight of a racquet, remember that heavier tennis racquets offer more power and less control while lighter racquets yield more control at the expense of power. The shape of your racquet determines where the sweet spot is: Traditional oval racquets have a sweet spot at the bottom, and a teardrop racquet features a larger sweet spot overall.

The ATP World Tour Masters 1000 is a group of nine tournaments that form the second-highest echelon in men's tennis. Each event is held annually, and a win at one of these events is worth 1000 ranking points. When the ATP, led by Hamilton Jordan, began running the men's tour in 1990, the directors designated the top nine tournaments, outside of the Grand Slam events, as "Super 9" events.[87] In 2000 this became the Tennis Masters Series and in 2004 the ATP Masters Series. In November at the end of the tennis year, the world's top eight players compete in the ATP World Tour Finals, a tournament with a rotating locale. It is currently held in London, England.[88]
Size. The overall size of a regulation tennis court for doubles play is 60 x 120 feet (per the International Tennis Federation). However, you must allow additional space around the court perimeter to give the contractor room to work and to permit the installation of drainage, landscaping, and fencing. Munson recommends leaving at least 12 feet between the court sidelines and the closest fixed obstructions, and 21 feet between the baselines and fixed obstructions. Where space is limited, you can downsize to a slightly smaller court. ITF recommends a minimum court size of 56 x 114 feet. An NBA/NCAA regulation full-size basketball court is 94 feet long and 50 feet wide. For backyards without enough acreage for a pro court, half courts can suffice for one-on-one games. (See this diagram of court dimensions from Half Court Sports.)

For right-handed players, the backhand is a stroke that begins on the left side of their body, continues across their body as contact is made with the ball, and ends on the right side of their body. It can be executed with either one hand or with both and is generally considered more difficult to master than the forehand. For most of the 20th century, the backhand was performed with one hand, using either an eastern or a continental grip. The first notable players to use two hands were the 1930s Australians Vivian McGrath and John Bromwich, but they were lonely exceptions. The two-handed grip gained popularity in the 1970s as Björn Borg, Chris Evert, Jimmy Connors, and later Mats Wilander and Marat Safin used it to great effect, and it is now used by a large number of the world's best players, including Rafael Nadal and Serena Williams.[77]
A break point occurs if the receiver, not the server, has a chance to win the game with the next point. Break points are of particular importance because serving is generally considered advantageous, with servers being expected to win games in which they are serving. A receiver who has one (score of 30–40 or advantage), two (score of 15–40) or three (score of love-40) consecutive chances to win the game has break point, double break point or triple break point, respectively. If the receiver does, in fact, win their break point, the game is awarded to the receiver, and the receiver is said to have converted their break point. If the receiver fails to win their break point it is called a failure to convert. Winning break points, and thus the game, is also referred to as breaking serve, as the receiver has disrupted, or broken the natural advantage of the server. If in the following game the previous server also wins a break point it is referred to as breaking back. Except where tie-breaks apply, at least one break of serve is required to win a set.
Standard squash rackets are governed by the rules of the game. Traditionally they were made of laminated timber (typically Ash), with a small strung area using natural gut strings.[8] After a rule change in the mid-1980s, they are now almost always made of composite materials such as carbon fiber or metals (graphite, Kevlar, titanium, and/or boron) with synthetic strings.[8] Modern rackets are 70 cm long, with a maximum strung area of 500 square centimetres (approximately 75 square inches) and a mass between 90 and 200 grams (4–7 ounces).

Further, the patenting of the first lawn mower in 1830, in Britain, is strongly believed to have been the catalyst, worldwide, for the preparation of modern-style grass courts, sporting ovals, playing fields, pitches, greens, etc. This in turn led to the codification of modern rules for many sports, including lawn tennis, most football codes, lawn bowls and others.[9]
