Planning for growth is smart. A common rule is to reserve about 20–30% more ports than you currently need to accommodate new devices and VLANs, especially if you anticipate PoE devices or a separate switch later. If you are already near the router’s port limit, it is usually cleaner to pair a multi-port router with a small managed switch now, rather than rework later. If you share your current device list and 12–24 month roadmap, we can map ports to each device and propose a concrete plan (which ports, whether you should use a switch now, and how to segment traffic with VLANs).
