"Up" Balloon Lift Calculator
Inspired by Pixar's "Up," this calculator determines how many standard helium party balloons would be needed to lift any payload. Based on real physics - an 11-inch latex helium balloon provides about 12 grams of gross lift, minus the weight of the balloon and string. Fun fact: lifting a house like Carl's would require around 65 million balloons! Enter your payload weight to discover your personal balloon requirement.
How We Calculate This
Net lift per balloon = gross lift - balloon/string weight. Required lift = payload × (1 + safety margin). Balloons needed = required lift ÷ net lift per balloon, rounded up.
Frequently Asked Questions
How many balloons lifted the house in "Up"?
According to calculations by Movoto and reported by Gizmodo, lifting a house like Carl's would require approximately 64,705,000 balloons. The movie shows far fewer for artistic reasons!
Why is the net lift only 10 grams per balloon?
A standard 11" helium balloon provides about 12 grams of gross lift, but the balloon material and string weigh approximately 2 grams. The net lift is the difference: 12g - 2g = 10g of actual lifting force.
What is the safety margin for?
The safety margin adds extra balloons to account for balloons that might deflate, pop, or have less-than-perfect inflation. A 20% margin means you get 20% more balloons than the absolute minimum needed.
Could this actually work in real life?
Theoretically yes, but practically no. The cluster of balloons would be enormous, wind would be a major problem, and you'd need a way to control descent. Plus, helium is a limited resource - please don't actually try this!
