How many balloons are needed for a balloon arch?
First, you need to know the length of the arch from one end to the other. We recommend using one of these two methods. Use some PVC pipe to get an idea of how big you want the balloon arch to be. Bend the pipe to form the arch at the same location where you want the balloon arch to be. See how it looks, and if you are happy with the size, measure the entire length of the PVC pipe used. (Later, you can use the same PVC pipe as the support for the arch. This is very desirable if you are setting up the balloon arch in an area where there may be wind or where you will have children or adults running around.) Or, you can get a rough idea of the height and width of the arch you need by measuring the following 1. If you want a wide balloon arch, simply add up the height and width of the area where the arch will stand to get a rough total length of the balloon arch . 2. If you need a round balloon arch, multiply the height by 1.5 and add it to the width. 3. To create a balloon arch...
