The old way
Sound familiar?
Buying clothes for the people you love shouldn't feel like a gamble.
"I think she's a medium? Or maybe a large now… she grew so fast."
"He loved it — but it didn't fit. Now I have to return it before Christmas."
"I haven't seen her in a year. I have no idea what size to buy."
1 in 3 clothing gifts is the wrong size. Right Fit fixes that.
How it works
Simple to set up. Saves you every time.
Three steps and you'll never guess a size again.
01
Add the people you love
Add family members and friends. Include their date of birth for smarter AI predictions.
02
Enter a few measurements
Chest, waist, and foot length is enough to generate a full size card — in US, EU, UK, and more.
03
Gift with confidence
Check their size card any time. Share it with family. Get reminders before birthdays.
“She loved it. And it actually fit for once.”
— Jamie, Right Fit user

AI predictions
Buy for who they'll be, not who they are now.
Kids grow 2–3 sizes per year. Buying for a birthday 3 months away? Right Fit predicts their size at that exact date — using CDC growth curves for children and AI for adults.
- CDC/WHO pediatric growth curves for kids
- AI-powered predictions for adults
- Confidence rating so you know how much to trust it
Gift reminders
Never scramble for a last-minute gift.
Add birthdays, holidays, and special occasions. Right Fit shows you exactly how many days you have to shop — with the right size already waiting for you.
- Automatic birthday events from date of birth
- Custom occasions: holidays, graduations, anniversaries
- Color-coded urgency so nothing sneaks up on you
