How Long Do Helium Balloons Last?
Planning when to pick up or inflate your balloons can make a big difference on the day of your celebration. Helium balloon float time depends on the balloon’s material, size, quality, temperature, and how it is handled.
Here is a simple guide to help you schedule your balloons correctly.
How Long Do Latex Helium Balloons Last?
Standard helium-filled latex balloons generally float for approximately 8–12 hours, although some larger, high-quality latex balloons may last longer under good indoor conditions.
Because latex is naturally porous, helium gradually escapes through the balloon’s surface. Larger latex balloons usually remain floating longer than smaller balloons.
For the best results, schedule regular latex balloon pickup or delivery as close as possible to your event.

How Long Do Foil Balloons Last?
Standard helium-filled foil balloons generally float for approximately 3–7 days. Some larger foil balloons may remain floating even longer when properly inflated and kept indoors.
Foil balloons hold helium longer because their material is less porous than latex. This makes them a good option when balloons need to be prepared before the celebration.
What Affects Balloon Float Time?
Balloon size
Larger balloons hold more helium and will normally remain floating longer than very small balloons.
Indoor and outdoor conditions
Balloons generally perform best indoors in a temperature-controlled environment. Hot, humid weather can reduce latex balloon float time, while outdoor wind and direct sunlight can weaken balloons.
Heat
Heat causes helium to expand. Balloons left inside a hot vehicle may expand and burst.
Cold temperatures
Cold temperatures cause helium to contract, making balloons appear soft or partially deflated. They may expand again after being returned to a comfortable indoor temperature.
Balloon quality and inflation
Correct inflation and a secure seal are important. Underinflated, overinflated or damaged balloons may not perform as expected.
