This is for 10G but still okay.

Read the section 3.1.3 ->

Step 1   Ensure log file sizes are identical on the primary and standby databases.

Step 2   Determine the appropriate number of standby redo log file groups.

It is written there..
So you should ensure that the standby redolog setup can support a dataguard switchover between the related primary and standby databases.. (as I already told you)
