Number of simulated pixels?

I’m thinking of building my next app with a pixelated look. I’ll be building in 4K portrait mode with a resolution of 2160 x 3840.

What ratio of number of pixel squares will I need to simulate a single pixel?

Thanks all

I might be wrong, but I think you should choose a very low resolution for pixelated game. It will be automatically upscaled to HD/4K/whatever resolution on the end-user device.
