Pixels, inches and DPI
Every size above is in pixels, because that is the only unit the platforms read. If you were asked for a header size in inches or centimetres, the header size units guide converts them and explains why DPI does not change what appears on screen. For one interactive table with device display sizes, use the header size calculator.
