Size of Rock 5A in comparison with Rock 5B and Raspberry Pi4

Can someone advice.
Is the size/dimension of Rock 5A is same as Rock 5B or same as Raspberry Pi4 ?
or is it completely different ?
Thanks in advance!

Same size as Raspberry Pi 4B, and connectors at the same place, so some RPi4 cases can be used.
