A racquet (or racket) is a sports implement consisting of a handled frame with an open hoop across which a network of cord is stretched tightly. It is used for striking a ball in such games as squash, tennis, racquetball, and badminton. Collectively, these games are known as racquet sports.

The frame of racquets for all sports was traditionally made of laminated wood and the strings of animal intestine known as gut; cat gut was most commonly used. The traditional racquet 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 racquets to improve stiffness. Non-wood racquets were made first of steel, then of aluminium, and then carbon fiber composites. Wood is still used for real tennis, racquets, and xare. Most racquets are now made of composite materials including carbon fibre, fiberglass, metals such as titanium alloys or ceramics.

Gut has partially been replaced by synthetic materials including nylon, polyamide, and other polymers. Racquets are restrung when necessary, which may be after every match for a professional or never for a social player.

Badminton

Badminton racquets

Badminton racquets are light, with top quality racquets weighing between about 80 and 100 grams (with strings). Modern racquets are composed of carbon fibre composite (graphite reinforced plastic), which may be augmented by a variety of materials. Carbon fibre has an excellent strength to weight ratio, is stiff, and gives excellent kinetic energy transfer. Before the adoption of carbon fibre composite, racquets were made of wood to their excessive weight and cost.

There is a wide variety of racquet designs, although the racquet size and shape are limited by the Laws. Different racquets have playing characteristics that appeal to different players. The traditional oval head shape is still available, but an isometric head shape is increasingly common in new racquets.

Rackets

This predecessor to the modern game of squash, rackets, is played with 30½ inch (775 mm) wooden racquets. While squash equipment has evolved in the intervening century, rackets have changed little.

Racquetball

According to the current USA Racquetball rules there are no limitations on shape or weight of a racquetball racquet.

Rule 2.4 RACQUET SPECIFICATIONS

1. The racquet, including bumper guard and all solid parts of the handle, may not exceed 22 inches in length.
2. The racquet frame may be any material judged safe.
3. The racquet frame must include a cord that must be securely attached to the player's wrist.
4. The string of the racquet must be gut, monofilament, nylon, graphite, plastic, metal, or a combination thereof, and must not mark or deface the ball.
5. Using an illegal racquet will result in forfeiture of the game in progress or, if discovered between games, forfeiture of the preceding game.

Racquetball racquets, unlike many other types, generally have little or no neck; the grip connecting directly to the head. They also tend to have head shapes that are notably wider at the tip, some even verging on triangular.

Real tennis

Tennis racquets and balls

The 27-inch (686-mm) long racquets are made of wood and use very tight strings to cope with the heavy ball of real tennis. The racquet head is bent slightly to make it easier to strike balls close to the floor or in corners.

Squash

'Standard' squash racquets 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. After a rule change in the mid-1980s, they are now almost always made of composite materials or metals (graphite, Kevlar, titanium, and/or boron) with synthetic strings. Modern racquets are 70 cm long, with a maximum strung area of 500 square centimetres (approximately 75 square inches) and a weight between 110 and 200 grams (4–7 ounces).

Tennis

The parts of a tennis racket are the head, rim, face, neck, and handle.

Modern tennis racquets vary in length, weight, and head size. 21" to 26" is normally a junior's length, while 27" or 27.5" are for stronger and taller adult players. Weights of a racquet also vary between 8 ounces unstrung and 12.5 ounces unstrung. Head size also plays a role in a racquet's qualities. A larger head size generally means more power, and a larger "sweet spot" that is more forgiving on off-center hits. A smaller head size offers more precise control. Head sizes of recent racquets vary between 88 sq. inches and 137 sq. inches as the Pro Staff 6.0 (85 sq. inches) went out of production last year.

Throughout most of tennis' history, racquets heads were around 65 square inches and racquets were made of laminated wood. In the late 1960s, Wilson produced the T2000 steel racquet with wire wound around the frame to make string loops. It was popularized by American top player Jimmy Connors. In 1975, aluminum construction allowed for the introduction of the first "oversized" racquet which was manufactured by Weed. Prince popularized the oversize racquet, which had a head size of approximately 110 square-inches and opened the door for the introduction of racquets having other non-standard head sizes such as midsize 90 square-inches and mid-plus size 95 square-inches. In the early 1980s, "graphite" (carbon fibre) composites were introduced, and other materials were added to the composite, including ceramics, glassfibre, boron, and titanium. The Dunlop Max200G used by John McEnroe from 1983 was an early graphite racquet, along with the very popular Prince "Original" Graphite. Composite racquets are the contemporary standard.

Longer racquets were introduced by Dunlop^[1] in order to give additional reach for shots such as the serve and volley where shorter players may be at a disadvantage. Midsize or mid-plus racquets are the general standard for professional players.

Stringing (material, pattern, tension) is an important factor in the performance of a tennis racquet. A few elite players use natural gut, but the vast majority of strings are a nylon or polyester synthetic. Some (American champion Pete Sampras is a prominent example) consider the natural string to be more responsive, providing a better "feel", but synthetic is favored for its much superior durability, consistency, as well as much lower cost. String pattern (the vertical/horizontal grid) is a function of the racquet head size and design. A tighter pattern is considered to deliver more precise control; a more "open" pattern to offer greater potential for power and spin. Modern racquets are marked with a recommended string tension range. The basic rule is that a lower tension creates more power (from a "trampoline" effect) and a higher string tension creates more control (the less 'trampoline effect' the more predictable the power and angle of the departure from the string bed.)

Double strung tennis racquets were introduced in 1977^[2] and then banned because they permitted excessive spin ^[3]. A modern version of a legal double strung racquet has been introduced ^[4].

Table tennis

Table Tennis racquet with 3 different sizes of the celluloid ball

A table tennis racket is used by players in the game table tennis. The racket is made from laminated wood covered with rubber on one or two sides depending on the grip of the player. This is called either a paddle, racket, blade or a bat depending on where in the world the game is being played. In the USA the term "paddle" is common, in Europe the term is "bat," and the official ITTF term is "racket."
