# How Many 11" Balloon Quads

Spiral balloon column with 3 feet topper [Source: www.balloons.com.au]

I am making 10' Spiral Columns with a 3' round on top. Pretty simple and basic. Just curious to know what the formula is in precisely determining the number of quads needed to build each column. The end result, all quads plus the 3' round, latex topper should be 10' tall. Thank you for your assistance in advance.

Hello Ida,

For a balloon column, you can use the same formula as you would for spiral balloon arches (i.e. arches made with balloon clusters), which is...

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

With a 3' topper, you'll have about 7' of balloon column left for the quads to get your total height of 10'.

Using 11" balloons, you'll need 6 per foot.

7 foot x 6 balloons = 42 balloons per column

Hope that helps!

Best,
Margit
