Fun fact: An MIT study found that the average width of the index finger is around .6-.7 inches for most adults, which is equal to 45-47 pixels. And many users utilize their thumbs (about 1 inch wode) to click buttons on a mobile screen.
Why is that important, you may ask?
If you are a product designer, that's crucial to creating accessible designs for your digital products
I never considered this fact from a UX/Design perspective... But aren't pixels dependent on the screen resolution? I think the "study" misses more context here.
Yeah, it is dependent. The study is focused on mobile devices where there is less variation. And it's just a rule of thumb anyway
