Baby Clothing Size Guide
Learn how to choose the right sizes and types of clothing for your baby.
Understanding baby clothing sizes can be confusing with different brands using different measurements. This guide helps you navigate sizing and choose appropriate clothing for your growing baby.
Newborn Size
Newborn sizes (up to 8 lbs) fit babies from birth to about 2-3 weeks. However, many babies skip this size and go straight to 0-3 months.
0-3 Months Sizing
This is the most common starting size for newborns. It typically fits babies up to 12 lbs or about 3 months old.
3-6 and 6-12 Months
As your baby grows, you'll move through these sizes. Growth can vary, so have larger sizes ready even if they don't fit yet.
Choosing Appropriate Styles
Select clothing based on weather and ease of diaper changes. Onesies, rompers, and two-piece sets are practical options.
Growth Considerations
Babies grow quickly. Have multiple sizes on hand and plan to purchase new clothing every few months as your baby grows.
