Growing possibilities.
Children grow. Their prosthetic hands need to keep up. We’re a student-led project exploring how AI can make the first step in sizing easier for families and makers.

What do I need for a photo?
A phone or camera, even lighting, a plain surface and any standard-size card (85.60 × 53.98 mm), such as a standard-size ID, credit or debit card. Include the entire intact hand, wrist and all four corners of the standard-size card.
Which prosthetic hand is supported?
The tool currently maps measurements to the e-NABLE Phoenix sizing table. Your maker or prosthetist should confirm model suitability and the final fit.
Is this a medical fitting?
No. It provides estimated measurements and a starting print scale. It does not assess whether a prosthesis is appropriate or replace an individual fitting.
Will my photo be stored?
No. The application processes it in memory and discards it after analysis. Your preview remains in the page until you clear it or leave.
