At 9plus1 we stock baby clothes in sizes from 0 to 18 months. Judging which size clothes to rent can be tricky, so to help you choose the best fit for your child, please see our size guide below.

There's a few things to note when choosing the best fitting clothes for your baby:

1. Sizing can be based on both age, weight and length
2. Baby brands are not consistently sized the same way
3. The size range on the label is often the maximum size
4. Sizing clothes by length rather than age can be helpful as some brands run small or large
5. There’s no one-size-fits-all rule! Some newborns fit into size 3-month clothes and some two-year-olds fit into size 12-18 months

We believe that you should be guided by your baby’s length and weight rather than by their age.
