How do I inflate a latex balloon?

Modified on Wed, 24 Feb 2021 at 06:40 PM

A perfectly inflated latex balloon is generally shaped like a teardrop. An under-inflated balloon will look like a beach ball whereas an over-inflated balloon looks like a lightbulb. Some larger latex balloons generally larger than 24 inches may blow up rounder.

Tips to Inflate the Perfect Teardrop Latex Balloon

  • Stretch the latex balloon with your hands before inflating the balloon.
  • If the balloon begins to bulge, let some air out until it looks like a teardrop.
  • Keep inflating the balloon if it is shaped like a beach ball– except in those cases where the balloon is meant to blow up round.
  • Under-inflated balloons will be round in shape, have reduced float times, and will appear less shiny.
  • Never inflate the neck of a balloon because this space is needed to tie the knot.
  • Overinflated balloons have a light bulb shape and are more likely to pop because the latex is so stretched out.
  • Once the body of the balloon is inflated, the air/helium will displace into the neck creating a bulge and making it more difficult to tie.
  • Using a balloon sizer will always guarantee a perfectly shaped and sized balloon (eg. Slide-N-Size, Balloon Sizing Templates, balloon sizing box). 
  • Under-inflated balloons are great for games that require sitting or stomping. They are challenging to pop, however, they are not visually appealing when used as decor.
