The frame of rackets for all sports was traditionally made of solid wood (later laminated wood) and the strings of animal intestine known as catgut. The traditional racket size was limited by the strength and weight of the wooden frame which had to be strong enough to hold the strings and stiff enough to hit the ball or shuttle. Manufacturers started adding non-wood laminates to wood rackets to improve stiffness. Non-wood rackets were made first of steel, then of aluminum, and then carbon fiber composites. Wood is still used for real tennis, rackets, and xare. Most rackets are now made of composite materials including carbon fiber or fiberglass, metals such as titanium alloys, or ceramics.

A game consists of a sequence of points played with the same player serving, and is won by the first side to have won at least four points with a margin of two points or more over their opponent. Normally the server's score is always called first and the receiver's score second. Score calling in tennis is unusual in that (except in tie-breaks) each point has a corresponding call that is different from its point value. The current point score is announced orally before each point by the judge, or by the server if there is no judge.
The players (or teams) start on opposite sides of the net. One player is designated the server, and the opposing player is the receiver. The choice to be server or receiver in the first game and the choice of ends is decided by a coin toss before the warm-up starts. Service alternates game by game between the two players (or teams). For each point, the server starts behind the baseline, between the center mark and the sideline. The receiver may start anywhere on their side of the net. When the receiver is ready, the server will serve, although the receiver must play to the pace of the server.
A denser pattern is often considered to deliver more control, at the expense of spin potential. A more open pattern is often believed to offer greater potential for power and spin. However, how much power is produced by a player can be strongly influenced by how a player adapts to the characteristics of the racket. Some players may hit harder with a dense string pattern, producing faster shots because of the added control from the dense pattern. Rackets, including those of much of the wood era, are marked with a recommended string tension range. The basic rule is that a lower tension creates more power (from the trampoline effect) and a higher string tension creates more control (less string deformation which results in a more predictable the power and angle of the departure from the string bed.) Some professionals used small-headed rackets with flexible-material strings (natural gut) strung at very high tension. Examples include Pete Sampras and Björn Borg. Some used large-headed rackets with very inflexible-material strings (kevlar). Andrei Agassi is an example. Many professionals during the standard wood era strung at relatively low tension and used natural gut string; both decisions were to increase the trampoline effect for more power. By contrast, almost every professional player today uses the much stiffer polyester string in their much stiffer rackets which also have larger heads and which tend to be lighter. Madeline Hauptman sold a line of rackets, called the MAD RAQ, which featured a Star of David pattern (a six-pointed figure consisting of two interlaced equilateral triangles), as it used three strings instead of two for stringing the racket. This pattern is used in snowshoes. This stringing pattern was said to feature less string notching, improving string lifespan. It was even claimed that many pro shops refused to carry the racket because less string breakage would reduce string and stringing service sales. It has also been claimed that the racket is more difficult to string than a two string racket. However, the Wilson T-2000-type requires a great deal more time for stringing than a typical racket and rackets of that series were very popular. Whatever the cause of the failure of the MAD RAQ in the marketplace, it was the only time a snowshoe pattern was used in tennis. Hauptman switched her racket line to a two string diamond pattern (PowerAngle). This pattern had already been used in much earlier rackets but had not had much popularity. It is said to be easier to string than the MAD RAQ but does not have the benefit of reduced string notching, at least not to the same degree. The claim is that this diagonal pattern offers more comfort than a traditional square pattern.
"Carpet" in tennis means any removable court covering. Indoor arenas store rolls of rubber-backed court surfacing and install it temporarily for tennis events, but they are not in use any more for professional events. A short piled form of artificial turf infilled with sand is used for some outdoor courts, particularly in Asia. Carpet is generally a fast surface, faster than hardcourt, with low bounce.
Another theory is that the scoring nomenclature came from the French game jeu de paume (a precursor to tennis which initially used the hand instead of a racket). Jeu de paume was very popular before the French Revolution, with more than 1,000 courts in Paris alone. The traditional court was 90 ft (pieds du roi) in total with 45 ft on each side. When the server scored, he or she moved forward 15 ft. If the server scored again, he or she would move another 15 ft. If the server scored a third time, he or she could only move 10 ft closer.
In 2019, the Australian Open introduced a "super-tiebreak" for singles in the final set, replacing the previous format in which the final set would continue until one player was ahead by two games. The new format for the final set is similar to the "12-point tiebreaker", but with the winner being the first to 10 points instead of 7 (and they must still win by 2 points). Tennis Australia has called this a "10-point tiebreak", though this is inconsistent with the reasoning behind the naming of the "12-point tiebreaker", which represents the minimum total number of points (a score of 7–5); the same reasoning would make the new format an "18-point tiebreaker" with a minimum winning score of 10–8.

The rules of modern tennis have changed little since the 1890s. Two exceptions are that from 1908 to 1961 the server had to keep one foot on the ground at all times, and the adoption of the tiebreak in the 1970s. A recent addition to professional tennis has been the adoption of electronic review technology coupled with a point-challenge system, which allows a player to contest the line call of a point, a system known as Hawk-Eye.
