A Complete Guide to Baby Clothing Sizes for Australian Parents

If you’ve ever looked at a baby clothing tag and thought, Wait, what size is this actually? - you’re not alone! Baby clothing sizes can be confusing, especially with different brands using slightly different measurements. To help you out, we’ve put together this simple guide to baby clothing sizes in Australia, so you can shop with confidence (and avoid the frustration of buying something too small before your little one even wears it!)

Understanding Baby Clothing Sizes

In Australia, baby clothes are typically sized by age, such as 0000 (newborn) or 0 (6-12 months). However, as all parents quickly learn, babies don’t always fit neatly into these categories. Some grow fast, some are smaller than average, and different brands can vary in their sizing.  

Here’s a rough guide to standard baby sizes in Australia:  

Tips for Choosing the Right Size:

✔ Size up when in doubt: Babies grow so quickly that it’s often better to buy slightly bigger clothes to get more wear out of them.  
✔ Check the brand’s size guide: Some brands run small or large, so always compare measurements.  
✔ Consider the season: If you’re buying ahead, think about what the weather will be like when your baby fits into that size.  
✔ Second-hand is a great option: Preloved baby clothes are often barely worn (because babies outgrow them so fast!), so shopping second-hand can save you money while also being eco-friendly.  

Final Thoughts

Baby clothing sizes can be tricky, but with this guide, you’ll be better equipped to find the perfect fit for your little one. And remember, every baby is different - so don’t stress if they don’t fit into the “right” size for their age. Happy shopping!
