Baby Clothing Size (0-24 mos)

Determine baby/infant clothing size
The Industry standard is to use the age as the size when it comes to baby clothing. This is easy to deal with. But be aware of the fact that all babies are different, and they come in different sizes and shapes!

So when shopping for baby clothing, you can use the age size as a rough guideline. But we recommend that you always take time to measure your baby, and buy clothing based primarily on these measurements (weight and height). See our baby size charts below to determine the right baby clothing size:
