What Size Will They Be?
About the app
Buying clothes for later shouldn't require baby math.
What Size Will They Be? helps parents estimate what clothing or shoe size to buy based on what their child wears now and when they need it to fit.
Use it for seasonal clothes, holiday outfits, future sizes, and quick shoe-size estimates by age.
Simple, fast, and made for those moments when you're standing in a store trying to remember how old “18 months” will be next summer.
