Enter any width in the calculator above and it returns the exact 4:5 height instantly (height = width × 5 ÷ 4), or enter a height to get the width. It also works in reverse: paste any pixel size and it tells you the ratio.
No. 4:5 and 5:4 use the same numbers but swapped, so one is landscape and the other portrait. 4:5 is taller than it is wide; 5:4 is the landscape version.
