The size of stadium seats varies depending on factors such as seat type, usage requirements and venue design. The following are some common stadium seat size standards:

1. Single seat size

Seat height: Generally, it should be between 430~480mm. This height range can ensure that most spectators can naturally place their feet flat on the ground when sitting, maintain a comfortable sitting posture, and avoid discomfort in the legs due to too high or too low seat height.

Seat depth: Usually 400~450mm. Sufficient seat depth can ensure that the user's thighs can be fully supported, and prevent the thighs from hanging in the air due to the shallow seat surface when sitting for a long time, causing fatigue.

Seat width: The seat width of a single seat is not less than 450mm. For the VIP seats of some high-end stadiums, the seat width may reach 500mm or even wider to provide a more spacious and comfortable seating experience.

Backrest height: The height from the seat to the top of the backrest is generally between 650~800mm. The reasonable height of the backrest can effectively support the user's back and reduce back pressure.

2. Other related dimensions

Row spacing: The row spacing of domestic stands is mostly 0.8m, but there are also venues that adjust the row spacing according to specific needs, such as 850mm for ordinary audience seats and 1700mm for VIP seats. The setting of row spacing needs to consider the smooth access and comfort of the audience.

Seat spacing: The spacing between seats is also an important factor affecting the comfort of the audience. Generally speaking, the spacing between seats should be large enough so that the audience can enter and exit the seats freely while avoiding mutual interference.

3. Special needs seat size

VIP seats: The seat size of VIP seats is usually larger than that of ordinary audience seats to provide a more spacious and comfortable seating experience. For example, the seat width of VIP seats may reach 550mm or even wider, and the row spacing may also be larger.

Disabled audience seats: The seat size of disabled audience seats needs to be designed according to the special needs of disabled people, such as the seat width, row spacing, etc. may need to be larger so that disabled people can sit and stand up conveniently. At the same time, disabled audience seats also need to be equipped with corresponding barrier-free facilities, such as handrails, wheelchair parking areas, etc.
