Are transaction ids always the same length?

Do all bitcoin transaction ids (hashes) have the same length?

I guess it's defined somewhere here: https://en.bitcoin.it/wiki/Protocol_specification but still I couldn't find it.

Yes. The transaction ID is SHA256(SHA256(transaction)) as described here and thus always has a length of 256 bits (32 bytes).
