Baby Knitwear Size Chart
Designed to grow with your little one
Our signature Harper Clare knitwear is intentionally designed in a relaxed 0–3-month fit, rather than a traditional newborn-only fit.
Designed to comfortably suit little ones from approximately 50–62cm and up to 6kg, our knitwear has natural stretch and a relaxed shape that allows room for your baby to grow.
We love this fit because those precious newborn days pass far too quickly. Instead of choosing a piece that may only fit for a few weeks, our relaxed 0–3-month sizing is designed to give you more wear, more memories and more value from each piece.
What does our 0–3 month fit look like on a newborn?
On a fresh newborn, our knitwear is intentionally designed to have a relaxed, slightly oversized look. This gives your little one room to grow into their piece rather than outgrowing it within just a few weeks.
If your baby is only a few days old or within their first couple of weeks, you may notice the fit looks a little roomy and that's completely intentional. As your little one grows, the relaxed shape becomes more fitted while still allowing plenty of room to move and stretch.
We especially love this relaxed look for newborn photos, coming-home outfits and those beautiful first announcements.

Is Harper Clare true to size?
Our knitwear is intentionally designed with a relaxed 0–3 month fit. On a fresh newborn, pieces may appear slightly oversized, giving your little one room to grow.
Will 0–3 month knitwear fit a newborn?
Yes. Our signature knitwear is designed for approximately 50–62cm and up to 6kg, with natural stretch and a relaxed shape.
What size should I buy for a newborn?
Harper Clare offers both newborn and 0–3 month sizing, so you can choose the fit that best suits your little one.
Our newborn range is designed for a closer fit from birth, while our signature 0–3 month range has a relaxed fit with extra room to move and grow, making it a beautiful option for longer wear throughout those precious early months.
If you're shopping for a coming-home outfit or newborn photos, choose newborn for a closer fit or 0–3 months for a more relaxed look with room to grow.
