Size of empty UDP and TCP packet?

Question

What is the size of an empty UDP datagram? And that of an empty TCP packet?

I can only find info about the MTU, but I want to know what is the \"base\" size of these

Answer 1

See User Datagram Protocol. The UDP Header is 8 Bytes (64 bits) long.

The mimimum size of the bare TCP header is 5 words (32bit word), while the maximum size of a TCP header is 15 words.
