The theoretical maximum width of the air dome building can reach 180 meters, while the actual maximum span of the air dome building is 110 meters of "Shen Hua Ba Meng" project, with the longest length unlimited. The minimum height must be 30% of the width. And the maximum height shall not exceed 50% of the width. The minimum height and width ratio are primarily concerned with snow removal and wind load reduction, while the maximum height and width ratio is primarily concerned with the overall design of the building. In other words, to satisfy the height of 50 meters, the width of the building must not be less than 100 meters.

Generally speaking, those with a span of more than 40 meters and a floor area of more than 2,000 square meters have economic advantages. Furthermore, the larger the span and the larger the volume, the more obvious the cost advantage of the airdome structure.

Pervious to light rate should inspect different membrane material, use pervious to light rate big membrane material, do not need electric power illume during the day, but pervious light rate is bigger, membrane material suffers the erosion of ultraviolet ray more fierce, which will be shorten the service life of airdome from1/2 to 1/3.
