Google short url - max url length

Question

I'm playing with Google URL shortner API, i would like to know if is there any maximum length for the URL returned from google.

I mean, short URLs are called short url because they are short, so they should be at max x chars length. I would like to know what that x is.

Answer 1

There is no way of telling the true length of them, the URL's could one day get 1 character longer because they ran out of unique links.

But currently they are 5 characters long, with a mix of numbers, low and higher case letters.
