So you are saying each field is 2 bytes?

I'd recommend reading the RFCs, e.g. https://www.ietf.org/rfc/rfc768.txt. The UDP header has a fixed length of 8 bytes: Source Port, Destination Port (2 bytes each), Length (2 Bytes), and a (more or less optional) Checksum (2 Bytes).

Or maybe the TCP/IP guide.

Yep, UDP header fields are 2 bytes each.
