Baby Clothing Size Calculator

Weight is generally the most reliable indicator for baby clothing size. Many babies don't match the age listed on clothing tags. A large 3-month-old may need 6-month clothes, and a small 6-month-old may still fit in 3-month sizes.

There is no universal standard for baby clothing sizes. Each brand creates its own size chart. Carter's tends to run true to size, while some European brands run smaller. Always check the specific brand's weight and height guidelines.

Buy only a few outfits in each size, especially for the first year when babies grow rapidly. Many babies skip sizes entirely. Stock up on the current and next size only, and keep receipts for easy exchanges.
