Diaper Size Calculator
Diaper sizes are based on weight, and ranges overlap between sizes. Enter your baby's weight and age for a size and a rough monthly count.

Brands differ. Size up when you see leaks, red marks or tabs that barely close, even if the weight is still in range.
How this calculator works
