Data offset (4 bits) – specifies the size of the TCP header in 32-bit words. The minimum size header is 5 words and the maximum is 15 words thus giving the minimum size of 20 bytes and maximum of 60 bytes, allowing for up to 40 bytes of options in the header. TCP header explanation: TCP header in a message. For example, a web request uses the TCP/IP protocol. Upon a web request from the web browser, TCP adds a header to the HTTP data and sends it to the IP layer. On the webserver, TCP reads the header and finds the application address.

TCP segments are sent as internet datagrams. The Internet Protocol header carries several information fields, including the source and destination host addresses [2]. A TCP header follows the internet header, supplying information specific to the TCP protocol. This division allows for the existence of host level protocols other than TCP.
