My daughter is 5'10" and was always tall as a u-little which helped her up top and in goal. In the women's game, you are going to see college GKs at a lot of different heights but I'm guessing most P5 and top mid-majors have their primary GKs at 5'8" to 6'. There will be some that are shorter - the Colorado GK who graduated last spring (I think) was not tall (a number of years ago I saw a Fullerton GK play a 1st round tourney game v Stanford and their GK was 5'4" (I remembered her at 5'5" but just checked)) - and there will be some who are taller but think of the libero in volleyball - she looks "short" in a top program but they are usually around the same height as soccer GKs and the 6'4" middle blockers do not become GKs b/c as much as we want to think that covering the upper V is so important, far more shots require GKs to get down quickly (defend the low corner shot, 1v1s, etc.) and that is tougher as they get taller. Men's GKs have become enormous but the position is played differently and the athleticism is different.
Hope Solo? 5'9". Naeher? 5'9" Jane Campbell? 5'9". Abby Smith? 5'9". Ashlyn Harris? 5'9" (I did not know all of this, except for Hope and Jane, before searching)
