Happens to all square shapes.

A chessboard is 8 tiles wide and 8 tiles long, so it consists of 64 tiles covering an area of, well, 64 tiles.

Not all pixels are square, though! Does anyone remember anamorphic DVDs? https://en.wikipedia.org/wiki/Anamorphic_widescreen

  • Never mind anamorphic DVDs, all of them use non-square pixels. The resolution of DVD is 720×480 pixels (or squared pixels, referring back to the article); this is a 3:2 ratio of pixel quantities on the horizontal vs. vertical axes. But the overall aspect ratio of the image is displayed as either 4:3 (SDTV) or 16:9 (HDTV), neither of which matches 3:2. Hence the pixel aspect ratio is definitely not 1:1.

City blocks, too.

  • In the US...

    • Do people in Spanish cities with strong grids (eg Barcelona) not also use the local language equivalent of "blocks" as a term? I would be surprised if not. It's a fundamentally convenient term in any area that has a repeated grid.

      The fact that some cities don't have repeated grids and hence don't use the term is not really a valuable corrective to the post you are replying to.

    • While it is certainly more common in the US we occasionally use blocks as a measurement here in Sweden too. Blocks are just smaller and less regular here.
