Balloon arch with 4-balloon clusters

How many clusters of 4 balloons can fit on a 10ft length arch?

ANSWER:

How many 4 balloon clusters fit on a 10 foot arch depends on the balloon size you are planning to use.

To calculate the number of balloons needed for a clustered arch or garland, you divide the diameter of the balloon into the length of the arch and multiple by 4.8.

As a rule of thumb, here are some balloons per foot numbers for the most popular balloon sizes:

5 inch balloons = 12 per foot
9 inch balloons = 8 per foot
11 inch balloons = 6 per foot
14 inch balloons = 4 per foot

So, if you are using 11 inch balloons for a 10 foot arch, you'd need 10 x 6 balloons = 60 balloons.

60/4 = 15 clusters

15 clusters of 11" balloons fit on a 10 foot arch.

If you were to use 9" balloons, you'd need 10 x 8 = 80 balloons or 80/4 = 20 clusters.

The same principles apply when you want to know how many balloons you need for a classic balloon garland, i.e. a garland made with clusters of four balloons.

Juggling all these numbers can be challenging. So I've created a spreadsheet as an easy way to calculate the number of balloons needed for an arch or garland.

You simply enter the height and width of your arch and the balloon size you want to use, and the spreadsheet calculates the arch length and the number of balloons for you.
