KidsGroFo: Growth & Sizes 4+

Use the free KidsGroFo app to buy only the clothes that fit your child!


KidsGroFo is short for Kids Growth Forecast. The app calculates your child's current and future clothing sizes (for hats, shirts & jackets, trousers and shoes) based on their current body measurements and also shows which clothing size will fit in which season.

The development of the KidsGroFo app was supported by the Ministry of Economic Affairs of North Rhine-Westphalia, Germany.

The KidsGroFo app is not only for parents, but also for relatives and friends. They can connect with you via the app and then have access to a child's measurement data. So grandma and grandpa no longer have to ask what size your child needs - they can simply check the KidsGroFo app the next time they go shopping for your child.

Why use the KidsGroFo app?

You probably know your child's current clothing sizes. But do you know what size your child will be next year? Toddlers in particular grow 2 to 3 sizes in a year. If you use the KidsGroFo app to calculate your child's future clothing sizes, you can plan the purchase of some clothes in a clever way. Why not buy next year's winter jacket today when it's on sale?

You'll love the KidsGroFo app:

It's simple and intuitive to use. You can register in just a few steps and just as quickly add your child to the app.
You only need to enter your child's details to use the app. But it becomes even more useful when you connect with friends and family.

Your data is safe. Your child's measurements are stored anonymously on the KidsGroFo servers. Personal information about your child (such as photos) is only stored on your smartphone. We at KidsGroFo or third parties have no access to them.
