How big are ancient Egyptian ankhs?

Answer 1

inx (often called ankh today) is a hieroglyph meaning life or living. It is a symbol often depicted as if three-dimensional but its origins are as a two-dimensional written character.

In that sense it has no specific size, in exactly the same way as the English letter C - it is as big as you want to write it, but it can be represented very large and three-dimensionally on advertising or shop names.

The inx character was sometimes made into an amulet or magical protective symbol; these could again be any size from tiny to quite large, but generally a size that could be held comfortably in one hand (perhaps 8 inches or 20 cms tall).
