You can simply load the queue up to measure the data space used (various tools can make this easy - check out support pac IH03). Or perform some calculations allowing for the MQMD headers (200 bytes).
Log space is used for uncommitted messages. The IBM defaults are inadequate for most purposes.
The number of uncommitted messages depends on how the application works.
Best to have plenty of spare log space to avoid transactions being forceably rolled-back. Maybe take the IBM defaults and quadruple every figure.

Look at System Admin manual for how to calculate log size.
