Solved BeamNG gauges texture size

Hi, does anybody know a good size for the texture of the gauges for a car? Rectangular, aspect ratio of about 2:1, I just need a general size range in pixels.

I’m talking about this texture if anyone doesn’t get it or I called it wrong.

 

Or rather
Is 640x256 good or should it be bigger?

I guess it’s actually 10:4 ratio now

 

anything should work as long as it's a multiple of 2

the wendover for reference is 1024x128 and 200bx for additional reference is 1024x512

 

Thanks! I’ll propably x2 it then
