Outgrow: Kids Size Tracker

Never buy the wrong kids' clothing size again.

Outgrow tracks your children's wardrobes across 38+ brands and tells you exactly when each item will be outgrown — so you can shop ahead confidently and stop wasting money on clothes that don't fit.

The problem Outgrow solves

A size 6 at H&M fits completely differently than a size 6 at Carter's, Gap Kids, or Zara. The same child wears three different sizes depending on the brand. Add multiple kids, hand-me-downs, and clothes bought ahead — and keeping track becomes a full-time job.

Outgrow does that job for you.
