How many bytes of data does a typical HTTP get request consume. For instance if I request a page from the server through a browser how many bytes of data would be sent?

The typical maximum size of a packet sent / received (the MTU) is 1500 bytes for ethernet. When you factor in the IP and TCP overheads, and the size of a typical HTTP response header, that could well leave you ~1K left for file data in the first packet of a response.
The default value of the HTTP and HTTPS connector maximum post size is 2MB. However you can adjust the value as per your requirement. The below command to set the connector to accept maximum 100,000 bytes. If the http request POST size exceeds the 100,000 bytes then connector return HTTP/1.1 400 Bad Request.
