Kid's Onesie Sizing Scale:

PLEASE NOTE: that a lot of teenagers should use the Adult sizing scale (below) and not the "Kid's Onesie Sizing Chart" (generally from ages 12 and up). Size S (Adults) is similar to size 12 (Australian Sizing) in Kid's clothing, and size 140 / 125 (Kids) is similar to size 10 (Australian Sizing) in Kids clothing.

Sizing should be by worked out primarily by height. Weight can be a factor. As a general guide, Size 100 or 85 would be suitable for a 2-3 year old, Size 110 or 95 would be suitable for a 4-5 year old  and size 120 or 105 would be suitable for a 6-6 year old. The correct way to calculate the size is by height (as mentioned above), as follows. If you need help choosing the correct size, email us at office@squishyheaven.com.au or call 1300 696 637:
