Blowing Up Balloons to the Same Size
- How to Use/Make a Balloon Sizer -

Blowing up balloons to exactly the same size is one of the secrets of professional looking balloon decorations. How do you achieve that? By using a balloon sizer.

What is a Balloon Sizer?

A balloon sizer is a plastic, wooden or cardboard box with circular cut outs corresponding to various balloon sizes. The sizes of the holes usually range from 2 inches to 11 inches. Most of the commercially available balloon sizers are collapsible for easy storage and transportation.

You can get a balloon sizer from balloon suppliers, or from Amazon (see the two examples below).





How to Make a Balloon Sizer Yourself

You can also easily and inexpensively make one yourself. Take a square cardboard box, and - as shown in the video tutorial below -, mark out circles according to the sizes of the balloons you are going to blow up. Then, using a craft knife, carefully cut out the center of the circles.

Whether you buy one or make your own, the principle is the same. Blow up a balloon and pass it through the appropriate hole until it slightly touches the sides of the hole.

For the balloon decorations we are going to show you, the main sizes for your DIY balloon sizer should be 5" (13 cm) and 11" (28 cm).

Blowing up Balloons to the Same Size Using Two Chairs

Another easy way to achieve balloons of the same size is to take two chairs and set them up back to back, so that the distance between them equals the size of the balloon you are inflating.

The inflated balloon should pass between the chairs just slightly touching either side.
