Ideal and minimum layout viewports per device

Back to the index.

Last major update on 13 April 2014.

On this page I compare the ideal and minimum layout viewport widths of all mobile browsers in my collection.

Ideal
The ideal viewport dimensions. Measurements from this test page
Layout min
The minimum size of the layout viewport measured at this test page. It sets the layout viewport width to 5, so any browser that reports 5 effectively has no minimum layout viewport width.
Physical
The device dimensions in physical pixels. Mostly gathered from GSM Arena.
DPR
Device pixel ratio. Calculated by dividing the physical dimensions by the ideal dimensions.
Min viewport
Essentially the zoom factor relative to the ideal viewport that occurs when setting the layout viewport to its minimum dimensions. Calculated by dividing the ideal viewport dimensions by the minimum layout viewport dimensions.
Physical aspect ratio
Ratio of the physical dimensions
Ideal aspect ratio
Ratio of ideal dimensions
