The article discusses the concept of pixels, emphasizing their role as dimensionless units primarily used for counting rather than measuring length or area. Users express confusion over interpreting pixels as squares and highlight that a pixel is fundamentally a point sample that may include multiple color samples. Furthermore, the discussion touches on the variances in pixel size and shape depending on device implementation, and the ambiguity surrounding the use of pixels in terms of resolution versus actual physical dimensions. Overall, the consensus suggests that while pixels can imply a measurement of area through resolution counts, they are better understood as discrete units of information rather than conventional measures of space.
