Do you mean "max depth on transmission queue"? There is no such thing as "max depth on channel"
There is a manual called "Monitoring MQ" that gives good detail about these tpyes of things ....

Okay, you shoulds set the max msg length on your XMITQ to match that of the channel. If an application trys to put a large message, it immediately gets back a bad return code.
If the max msg len on the channel is lower than on the xmit queue, it will go to the local DLQ.
So are you looking for something like: "The average size of a message put to a xmitq is 7894 bytes and the max msg len is 10,000 bytes"?

thanks for this great information. Yes thats the average I am looking for . I guess making sure I match what in the channel with the xmit will resolve any future issue.

If you upgrade to MQ V6, you can turn statistics on for the xmitq and get information to dervice the average message size (putbytes / putcount). 
In V5.3, you would need to capture this data yourself via an API or channel message exit

Make sure as well that you NEVER use this channel as default pathway between any 2 qmgrs. You will never know what the message and / or its size is when the message uses a default pathway...
Enjoy
