Classes 1–5 are for those in wheelchairs and classes 6–10 for those who have disabilities that allow them to play standing. Within those groups, the higher classification means the more function the athlete has. Class 11 is defined for players with an intellectual disability.

Classification
The roles of classification are to determine eligibility to compete for athletes with disability and to group athletes equitably for competition purposes. Athletes are grouped by reference to functional ability, resulting from their impairment.

Sitting classes

No sitting balance, although the upper part of the trunk may show activity. Normal arms, although some slight motor losses can be found in the playing hand without significant effect on table tennis skills. The non-playing arm keeps the trunk in position. Existing sitting balance although not optimal because of non-existing anchorage (stabilisation) of the pelvis. Normal function of trunk muscles.

Laws of table tennis in wheelchair
There are no exceptions to the laws of table tennis for standing players with a disability. All players play according to the laws and regulations of the ITTF. The umpire may relax the requirements for a correct service if the compliance is prevented by physical disability.

Service
If the receiver is in wheelchair, the service shall be a let under the following circumstances:
 * 1) After touching the receiver's court, the ball returns in the direction of the net.
 * 2) The ball comes to rest on the receiver's court.
 * 3) In singles, the ball leaves the receiver's court after touching it by either of its sidelines.

If the receiver strikes the ball before it crosses a sideline or takes a second bounce on his or her side of the playing surface, the service is considered good and no let is called.

Doubles
When two players who are in wheelchairs are a pair playing doubles, the server shall first make a service, the receiver shall then make a return but thereafter either player of the disabled pair may make returns. However, no part of a player's wheelchair shall protrude beyond the imaginary extension of the center line of the table. If it does, the umpire shall award the point to the opposing pair.

Limb positions
If both players or pairs are in a wheelchair, the player or the pair score a point if:
 * 1) the opponent does not maintain a minimum contact with the seat or cushion(s), with the back of the thigh, when the ball is struck.
 * 2) the opponent touches the table with either hand before striking the ball.
 * 3) the opponent's footrest or foot touches the floor during play.

Wheelchairs
Wheelchairs must have at least two large wheels and one small wheel. If the wheels on the player's wheelchair become dislodged and the wheelchair has no more than two wheels, then the rally must be stopped immediately and a point awarded to their opponent.

The height of one or maximum two cushions is limited to 15 cm in playing conditions with no other addition to the wheelchair. In team and class events, no part of the body above the knees may be attached to the chair as this could improve balance.

Equipment and playing conditions

Table legs shall be at least 40 cm from the end line of the table for wheelchair players.
