How to use a size chart

Size charts are what brands use when they create the patterns that are eventually turned into their apparel. For the most part, us brands try and use the same sizing and attempt to maintain consistency across seasons so you can feel more confident in your choices, especially when shopping online. (We don’t always succeed, but we try!)
The most important thing to know is that the sizing on the size chart reflects the size of the kiddo the garment is meant to fit, not the size of the garment itself.

The next most important thing to remember is that these measurements reflect the average for that size, and it’s highly likely that your kiddo will fall across a few size ranges.

So how can you use a size chart when choosing what size you need to buy?

The first step is to decide which measurement is most important for the garment you are buying. For example, if it’s a tee, you might need to take into account the chest and waist measurement to make sure it’s not going to be too tight when they’re wearing it. If it’s pants, you might want to buy based on their height if you have a very tall kiddo, or it might be more important that you check the waist measurement if your kiddo is blessed with a chubby little tummy.

Here’s two examples for you.



Let’s take the fictional, Little Kiddo. He is 2 and a half, is 94cm tall, his chest is 52cm and his waist is 54cm. Little Kiddo would do best in a size 3, or if I am buying end of season stock, I’d buy him a size 4 for him to wear when the season rolled around again.

Let’s take Kinda Lanky Kiddo. Kinda Lanky Kiddo is actually 6 but is little-ish for her age. She is 108cm tall, has a chest of 55cm and a waist of 55cm. For this kiddo, a size 4 would be good for tops, but I’d probably get a size 5 if I was buying pants so they were long enough and for longevity of wear.

Ultimately, it really is personal preference, but I hope this at least gives you some idea of how you can use a Size Chart to choose the best size to buy for your kiddo.
