Are hash collisions with different file sizes just as likely as same file size?

I'm hashing a large number of files, and to avoid hash collisions, I'm also storing a file's original size - that way, even if there's a hash collision, it's extremely unlikely that the file sizes will also be identical. Is this sound (a hash collision is equally likely to be of any size), or do I need another piece of information (if a collision is more likely to also be the same length as the original).
Or, more generally: Is every file just as likely to produce a particular hash, regardless of original file size?
