Understanding Kids' Clothing Sizes: A Parent's Guide
Kids' clothing sizes can be confusing, with different brands using different measurements. Here's how to navigate it:
Size Charts Vary by Brand
Don't assume a size 4T in one brand equals a size 4T in another. Always check:
- The brand's specific size chart
- Your child's current measurements
- Reviews from other parents
Age vs. Size
Sizes like "2T" or "4T" are based on age, but kids grow at different rates:
- T sizes (2T, 3T, 4T): Typically for toddlers
- Regular sizes (4, 5, 6): For older kids
- Plus sizes: For larger children
Tips for Buying on TrunkMatch
- Ask for measurements: Sellers can provide chest, waist, and length measurements
- Check the brand: Research the brand's sizing if you're unfamiliar
- Buy slightly larger: Kids grow fast, so buying up a size extends wear time
- Read descriptions: Sellers often note if items run large or small
Common Size Conversions
- 2T ≈ Size 2
- 3T ≈ Size 3
- 4T ≈ Size 4
- After 4T, sizes typically go 5, 6, 7, 8, etc.
When in doubt, measure your child and compare to the item's measurements!
