How it works
1
Log what you have
Quickly add clothing items by voice or manually — brand, size, condition, source.
2
Set your kid's size
Tell Next Size what size they're in now. It looks ahead so you're always buying into the right window.
3
See your gaps
Get a clear list of what's missing — sorted by priority so you know exactly what to hunt for.
Built for families who buy smart
If you thrift, shop Poshmark, or stock up at end-of-season sales — Next Size keeps you from buying duplicates and missing the stuff that actually matters.
