What touchscreen supported by Volumio 3

HI
I am new on volumio, I have the V3 and plan to add touchscreen with hdmi & usb control port…
size from 5 to 7

On the net we have lots of screen.
Except the official raspberry PI 7 inch Touch display, how to choose one, 5 or 7 inch that is compliant.
Is there a method to check before buying ?

Thanks for your inputs

Georges.
