How long will your balloons float for?



There are many different factors that affect the float time of a helium-filled balloon. Foil balloons and bubble balloons have a longer float time than latex balloons. The size of the balloon is also a factor (generally, the bigger the balloon, the longer the float time). In addition, the temperature and conditions that the balloon is kept in can impact upon the length of time that it remains floating.


We always treat our (helium-filled) latex balloons with a sealant which coats the inner wall of the balloon. The sealant helps to stop the helium molecules escaping so quickly through the wall of the balloon and therefore increases the balloon’s float time. The average float time for a treated
standard size (11 inch) latex balloon is around three days. If untreated, a latex balloon of this size will only float for around ten to twelve hours.

The confetti-filled latex balloons have a reduced float time due to the extra weight of the confetti inside the balloon. 

It is important to be aware that, even when treated, your latex balloons will get smaller with each passing day as they gradually lose helium. When ordering latex balloons, we recommend that they are delivered (or collected) on the day of your event to ensure that they look their best for your celebrations.


In optimum environments, foil balloons will remain full and taught for three to five days. They will usually continue to float for longer but will appear less taught as they start to lose helium. Cool air may cause these balloons to shrivel but they will return to a normal state when back in room


Bubble balloons are likely to float for a few weeks. If your balloon has been personalised, the writing will start to bubble after a few days and gradually peel off as the balloon starts to slowly reduce in size.

All of the float times detailed above are average float times and apply to balloon friendly indoor environments. They are not a guarantee and are to be used as a guide only.
