Frequently Asked Questions

What kind of hats does this support?

RightFit3D supports all traditional hat styles including fedoras, bowlers, top hats, berets, and custom millinery pieces. Our algorithms are designed to work with any hat style that requires precise crown and brim measurements.

Do I need a 3D printer?

While having a 3D printer enhances your capabilities, it's not required. You can export measurements and work with traditional hat-making tools. We also offer an in-house 3D printing service for all STL files made with CrownFit3D or HatFit3D, so you can get your custom blocks printed and shipped directly to you.

What if I don't have a conformer?

You actually do need a conformer for the most accurate measurements. However, RightFit will be offering conformers at very reasonable prices to ensure you have all the tools needed for professional hat fitting. CrownFit3D can work with photo measurements using a credit card for scale as an alternative method, and HatFit3D includes 3D scanning capabilities for comprehensive measurements.

Can I use this for commercial hat businesses?

Our Master Craftsman tier is specifically designed for established hat-making businesses, offering white-label licensing, custom branding, and advanced analytics to help grow your business.
