The maximum height is 7 ft. Though, that's not an ideal height whatsoever. They'd be incredibly lanky and just weak and unhealthy and all that other shite. I'd say that the most ideal height is approximately 6'2" to 6'6", maybe even 6'5". 

YES i am the height of an elf

Depends on the subrace really. Wood elves tend to be the shortest, ranging from 5'3" to 6'.

Dark elves are a little taller, ranging from 5'10" to 6'4".

Then of course high elves are usually the tallest and go around 5'11" to 6'6".

These are all just averages of course sometimes you find one elf taller or shorter than usual.
