Despite that being a very odd question, I'll give it a shot using logic. According to the "Batman (Bruce Wayne)" page, Batman is 6'2' '. Since his cape is at his shoulders, we will have to subtract his head and neck from his actual height. The average person is 7 of their heads tall so, dividing 74 inches (Batman's height in inches) by 7, we can estimate his head is 10.5 inches tall. Adding a 1.75 inch neck, we can say Batman's shoulders are at 61.75 inches (5'1' '). His cape goes all the way to the floor, meaning it is a minimum of 5 feet long. However, usually, his cape drags on the floor slightly. The most I could estimate he would have it drag without it being obtrusive is 1 foot.

So, in conclusion, my final estimate, which could always be wrong since it is an estimate, is that it is no shorter than 5 feet but no longer than 6 feet. If you want a precise answer, let's use the median: 5'6' '.
