#1 reason for returns: wrong size

Size charts lie. A medium at Nike fits nothing like a medium at Zara. You end up ordering two sizes "just in case" and returning one. Sometimes both.

Three steps. That's it.

1

Tell us your size

Add a few items you already own that fit well. No measuring tape required.

2

Paste any link

Questions

How does FitPrint know my size?

When you add reference items (clothes you own that fit well), we use that data combined with each brand's actual size charts to calculate your size. If a Nike Medium fits you perfectly, we know your chest is roughly 38-40 inches and can recommend sizes at other brands accordingly.

Do I need a measuring tape?

Nope. The easiest way to use FitPrint is to add a few items you already own. Tell us the brand, size, and how it fits. We handle the math.

What if a brand isn't supported?

We're adding brands constantly. If we don't have data for a brand yet, we'll tell you upfront. You can still use FitPrint for the 60+ brands we do support.

Is my data private?

Yes. Your measurements are stored securely on our servers to enable size recommendations, but we never sell your data or share it with brands. If you use the photo feature, face detection and blurring happens on-device before anything leaves your phone. You can request deletion of your data at any time.

How much does FitPrint cost?

FitPrint is $1.99/month or $19.99/year (save 17%). Every new user gets a 1-month free trial to try it out.

What about international sizes?

We handle size conversions automatically. Whether you're shopping US, UK, EU, or Asian sizes, FitPrint figures out the equivalent.
