Hello everyone!

I’ve been exploring Figma for a while now and have been practicing different designs for both mobile and desktop screens. This time, I wanted to try something new and chose a self-ordering kiosk design for a fictional restaurant. Basically, I’m aiming for a countertop ordering terminal.

Right now, I’m a bit unsure about the correct frame size for this type of design. I went with 1920×1080 for now, but I’m not sure if that’s ideal.

My second question is about the font size. What would be the most suitable sizes for such a layout?  I’m working on the first three screens right now: a start screen (to begin an order) and another for selecting between take-out and dine-in. After that comes the first menu overview, where I’ll definitely need smaller fonts to fit more information, unlike the two before.

Could anyone share some advice on the best frame and font sizes for this kind of kiosk setup? And what is the best way to figure out how to choose the correct one? I know, that using too many is not the best and I would love some tips from those, who have more experience than I do.  

Thanks a lot in advance! :)
