Sizes Matter
Never call home from the store for a size again.
Sizes Matter keeps every size your family needs — kids' shoes, your AC filter, the batteries the remote takes, the tires on the car — and lets you share them with the people who shop for you.
Snap it. Confirm it. Done.
Point your camera at a tag, a filter frame or a battery. We fill in the size for you — you just check it.
Take a photo
The shoe tag, the filter's printed size, the tire sidewall, the old bulb.
We read it
Items other people already saved come back instantly. New ones are read by AI.
You confirm
A pre-filled card shows brand, model and size. Fix anything, then save.
Reorder in a tap
Every saved item has a shopping link with the exact size already in the search.
Profiles for everyone — and everything.
Make a profile for each kid, your partner, the house and every car.
Clothes, shoes, rings
Sizes, favorite brands and colors. Add a birth date and we'll remind you to re-check as kids grow.
Filters, bulbs, batteries
The AC filter for each unit, the bulb in every fixture, the batteries every remote and smoke detector takes.
Tires, wipers, oil filter
Tire size, wiper lengths, bulb codes, battery group and filter part numbers for every car.
Free, and it stays that way.
Every account starts with 50 free AI scans. Items someone else already scanned are free and instant. Invite friends for more scans. No ads, ever — and we never sell your information.
