Essentially the same size. They ended up with 132 bits because they use a 6 bit alphabet; 128 is not divisible by 6, so you would need 22 characters of a 6 bit alphabet to represent a UUID, exactly the same as them.
(note, the 6 bit alphabet is so identifiers can go in urls; the commonly used uuid hexadecimal representation is a 4-bit alphabet, so there are 32 characters and usually 4 hyphens; so 36 characters in the URL vs. only 22)
