The [[ ITTF.com|ITTF]] rules require a 40 millimeter ball and 2.7 grams. The balls are rated by stars. With one star the lowest and four stars the highest. They have recently changed from 38mm to 40mm. The newest one is harder to spin than a 38mm but it is still a good ball.

The international rules specify that the game is played with a light 2.7 gram, 40 mm (formerly 38 mm) diameter ball. The ball is required to have a coefficient of restitution of 0.4. The 40 mm ball was introduced at the 2003 World Table Tennis Championship. However, this created some controversy as the Chinese National Team complained that this was merely to give non-Chinese players a better chance of winning. A 40 mm table tennis ball is slower and less "spinny" than a 38 mm one. The ball is made of a high-bouncing gas-filled celluloid ball, colored white or orange, with a matte finish. The choice of ball colour is made according to the table colour and its surroundings. For example, a white ball is easier to see on a green or blue table than it is on a gray table.

Players are equipped with a wooden paddle (also known as racquets or bats) covered with rubber on one or two sides.

Recent years have seen an advancement in technology of table tennis blades (a bat without rubber). Materials of different properties may be combined with the wood in the blade to enhance its playing performance. Many blades today feature one or more carbon layers within them to enhance their 'sweet spot', and to give the player a greater margin of error when playing powerful shots. Materials incorporated into table tennis blades today include kevlar, titanium, arylate, aramid, and aluminium.

The rubber coating may be of pimpled rubber, with the pimples outward, or it may be a rubber that is composed of two materials, a sponge layer, covered by a pimpled rubber, with the pimples pointed inwards or outwards. Some rackets are not covered with rubber at all, because a "naked" racket is believed to be more resistant to a spin however it is illegal to use these types of rackets in competition as they are not approved by the ITTF. Some types of racket rubbers are also not approved. Approved rubbers have the ITTF emblem on the base of the rubber.[7]
Players have many choices and variations in rubber sheets on their bat. Although bats may be purchased with rubber by the manufacturer, most serious tournament players will create a customized racket. A player selects a blank blade (i.e. a bat without rubber), based on his playing style. The type of wood and synthetic layers used to make up the blade will provide a slower or faster blade. The player can choose from different types of rubber sheets which will provide a certain level of spin, speed and specific playing characteristics.

Normally, a sheet of rubber is glued to a blade using rubber cement and not removed until the rubber wore out or becomes damaged. In the 1980's, a new technique was developed where the player would use a special glue called speed glue to apply the rubber every time he played. The glue would help provide more spin and speed by providing a "catapult" effect. This technique is known as "regluing" and has become a standard technique for top players.

Table tennis is the only racket sport that allows different surfaces on each side of the bat. The different types of surfaces provide various levels of spin or speed, or in some cases, nullifies spin. For example, a player may have a rubber that provides much spin on one side of his bat, and no spin on the other side of the bat. By flipping the racket in play, different types of returns were possible. To help a player distinguish between different types of rubber used by his opposing player, international rules declared that one side must be red while the other side must be black. The player has the right to inspect his opponent's bat before a match to see the type of rubber used and what color it is. Despite high speed play and rapid exchanges, a player can see clearly what side of the racket was used to hit the ball.
