What length is her hair?

I would categorize any hair shoulder length and below would be long hair.

What an odd question. If you don't consider that to be a long length, then what counts as long to you?

Just the right length...yowza...perfect.

longer than the area of neck and past the shoulder ridge by approximately 5 - 6 inches  based on the photo and average female proportion measurements estimating each sewing line  of the garment worn  is spaced is average of  1-1/2 to 2 inches apart  the hair length reaches the 3rd sewing line

long.......................

Her hair is longer than medium but not extra-long.

I'd say long but not super long.

who tf cares.................

It's long, not medium that would be around shoulder length. If some one's hair is past their shoulders then it's long to me. 

I call "medium" hair that reaches to the shoulders, so this would be long IMO.
