Here are detail and calculations from Qualatex for making a balloon ceiling.


A balloon ceiling can instantly transform a large boring space into an inviting party atmosphere. It creates a festive mood, bringing the room to life with a wide expanse of color and the motion of fluttering ribbons. Plus, it’s easy to customize for any occasion or special event.


How many balloons do I need to make a balloon ceiling?


Calculate the square feet of the ceiling (width x length), and divide this by the square feet covered by each balloon.


  • 11-inch balloon = .66 sq. ft. (613cm2) covered by each balloon
  • 16-inch balloon = 1.4 sq. ft. (1301cm2) covered by each balloon
  • 3-foot balloon = 7 sq. ft. (.65m2) covered by each balloon

Example: 10 ft. (3.05m) x 10 ft. = 100 sq. ft. (9.3m2) divided by .66 (for 11-inch balloons) = 152 balloons


Quick Tips


With a little ingenuity and some additional supplies, you can achieve the magical effect of a balloon ceiling without any helium! Plus, the balloons don’t have to make direct contact with the ceiling, which reduces the risk of popping due to certain building materials, rough surfaces, or hot lights.
