If I were doing it I’d just scan an image of my hand in at a high resolution and then use measurement tools in Photoshop or something similar. Should even be possible to do in MS Paint by taking pixel coordinates and doing a little trigonometry. It’s the ratio that’s important, so it shouldn’t matter if the measurements are denominated in pixels or inches.
(I didn’t do this on my survey because I took it at work.)

I can confirm that the MS Paint method works.
As I lack both a scanner and calipers, I just took a picture of my hand with my phone.
