Spatial resolution reflects how finely an image can reproduce small structures, and in digital imaging that quality depends on how densely the image is sampled by pixels. When pixel size is smaller, each pixel covers less area, so more pixels sample the same region, capturing finer detail and increasing the ability to separate adjacent structures. Conversely, larger pixel size merges signals from nearby features and blurs detail, lowering resolution. Therefore, smaller pixel size yields higher spatial resolution. The idea that larger pixels improve resolution or that pixel size doesn’t matter goes against this basic sampling relationship and how image sharpness is determined by pixel density.
