For the graph on the right, why are we finding partial derivatives with respect to x? What does this math operation mean?

The idea is to see how big pixels in the rendered image are relative to the pixels in the texture map. I’d x refers to a pixel on the screen and u refers to a pixel in the texture then du/dx = 1 means that the pixels are the same size (horizontally), if du/dx were greater than one it would mean the image pixels are larger/wider.

Why isn't it when du/dx is greater than one meaning the image pixels are "smaller/thinner"?
