Better check the performance of your current network. Check the
bandwidth utilization, error rate, throughput, and so on. Then you can
determine whether it's time to break up certain segment into smaller
ones.
For the subnet /24. If a client is set to the mask /16, if its
destination is out of the /16 segment, since it thinks it is a local
address then it sends ARP broadcast first (which is not necessary)
before sending the packet to the next hop router. If a client is set
to a larger subnet mask, say /25, then it may needs to send its packet
to the next hop router instead of just sending an ARP broadcast.
