Shouldn't 1 at pixel ratio of 2 be 4 pixels?

Since it's being doubled both vertically and horizontally, the 1x1 pixel becomes a 2x2 square, aka 4 pixels.

Hi Ian,

Think of the device pixel ratio as a linear measurement. One direction only.

1 css pixel equates to 2 horizontal physical pixels or 2 vertical physical pixels.
