Cross-category guides

Compare screens across device types.

A phone diagonal, TV diagonal, and monitor diagonal do not answer the same practical question. These guides normalize the geometry and explain the tradeoffs.

Comparison guide types

01

Normalize the units

Every screen is converted to the same physical unit before its geometry is compared.

02

Respect the shape

Aspect ratio explains why equal diagonals can produce very different widths and heights.

03

Separate pixels from size

Resolution and PPI stay distinct from physical area, so “bigger” and “sharper” are never conflated.
