3 Ways To Size A Balloon – Plus DIY Balloon Sizer


Balloon sizing, what does that mean? And why do I need to know 3 different ways to do it? In today’s post, I’m going to show you 3 ways to size a balloon. One of them being a DIY balloon sizer so your balloons can always look amazing!

What Is Balloon Sizing

Balloon sizing as it’s often called in the balloon industry is a fancy way of saying making all your balloons the same size. And you don’t necessarily need 3 ways of sizing a balloon but they all come in handy at different times.

Why Do I Need To Size My Balloons

Ok so now that we know what it is, why is balloon sizing so important?

Balloon sizing is important because it is what makes your balloon creations stand out from a first-time balloon inflator to making your balloons look awesome and professional! Three ways to size a balloon are the hand pump method, the eyeball method, and the balloon sizer method.

Three Ways To Size A Balloon

The Hand Pump Method

The first way is probably the most accurate but it’s also the most time-consuming. You are going to need your hand pump and you’re going to count how many pumps you do.

This particular method might be used if you only had a couple of balloon columns to make or if you wanted to make sure all your balloons were as close to the same size as possible. It might also be used if you had several people helping build balloon columns (or whatever decoration you are creating). This method would ensure all the columns came out the same size.

The Eyeball Method

The second method is the least accurate method and I wouldn’t recommend it unless you were in a pinch. This method is exactly as it sounds, you inflate one balloon and then the second one and you hold them up side by side, letting air out from one of the balloons until they appear to be the same size.

This balloon sizing method might be used if you need to quickly replace a deflated balloon in your decor. Or maybe you need to replace a couple of balloons quickly. I know this method has saved my butt on more occasions than I would care to admit.

DIY Balloon Sizer Method

Last but certainly not least the DIY Balloon Sizer Method. I’m gonna show you how to make a balloon sizer out of a cardboard project map.

First I’m going to start out by making circles of different sizes in the cardboard project map. Next using a ruler and a protractor draw out your circles on the cardboard project map in different increments.

Then using an Exacto knife I’m going to cut out all the circles. Make sure when you’re using your Exacto knife you have a mat underneath so you don’t cut whatever is underneath.

Next number each hole with the size hole that it is.

And then you are all set to size balloons until your heart’s content. The key is to blow up the balloons slightly past the size that you want and then as you stick the balloon through the hole you let the air out until it fits through the hole. Make sure you don’t let the air out too fast or the balloon will deflate too much. When the deflated balloon can pass through a hole but still touches the sides of the balloon sizer your balloon is properly sized.

The cool thing about this balloon sizer is you can use it over and over and over again and you don’t have to remake the thing. Some other posts you might enjoy are How To Stuff A Balloon, Simple Balloon Column, and Sturdy Balloon Bubbles.
