Helium Balloons Calculator

Find how many balloons lift a given weight.

Weight to lift

Lift per balloon

Balloons needed 20

Formula: balloons = weight ÷ lift per balloon

Step-by-step with your numbers:

1. Values used:

2. Weight to lift = 100

3. Lift per balloon = 5

5. Balloons needed = Weight to lift / Lift per balloon = 100 / 5 = 20

Did we solve your problem today?

Estimate how many helium balloons it takes to lift something.

The math behind it

balloons = weight ÷ lift per balloon. A standard 11-inch latex balloon lifts ~5 g.

100 g at 5 g/balloon → 20 balloons.

Foil balloons?

Larger foil balloons lift more — adjust the lift per balloon.
