Size guide
Just like the rest of us, babies come in all shapes and sizes. Here are some top tips on which sizes to buy when shopping with us. And if you’re still unsure of what size to get — don’t miss our 2-in-1 sizes with room-to-grow features.
Size it right
• Use our size charts for clothes, socks, shoes, mittens and hats
• For clothing, go by height and chest size, rather than age
• Measure from the top of baby’s head to the bottom of the heel (height) and under the arms at the widest point (chest)
• Check out our ‘true to size’ scale for products online, based on customer reviews

Room to grow
• Baby on the way? Don’t shop too much; you’re likely to receive gifts of clothing in the smallest size
• Keep that mindset and never buy too much in one size — babies always grow quickly!
• If in doubt, size up so that your baby can grow into it (that goes for you too, gift-givers)
• Babies grow fast, so we've made garments with 2-in-1 sizes that grow with your baby, and can be loved for longer.
