Helium – General Information
How much helium do I need?
Latex Helium Chart
Use this chart to estimate helium needs for latex balloons. Volume and lift ability are average estimates. Float times for latex balloons vary widely with temperature and atmospheric conditions. Larger balloons will float for longer periods of time and float times can be increased by using Hi-Float™.
