PoE, 2.5G and aggregation switching from the $29 Flex Mini to 48-port ProAV machines. Count your PoE devices, add two spare ports, and buy that — the honest sizing rule.

Nothing matches that combination.

How many PoE ports do you actually need? The PoE budget calculator adds up your APs and cameras, then names the switch that powers them with headroom.

GUIDE

How to choose a UniFi switch

Count PoE devices, not total ports

Every AP and camera draws PoE. Add them up, add two spare ports for the future, and check the wattage budget — a Lite 8 PoE powers four PoE+ devices comfortably; eight cameras and three APs wants a Pro Max.

2.5G matters where Wi-Fi 7 lives

A Wi-Fi 7 client on 6 GHz can outrun a gigabit port. Feed U7-series APs from a 2.5G switch port and the whole path stays clear — the Flex Mini 2.5G at $49 is the cheapest fix in networking.

When in doubt, go one size up

The price step between switch sizes is small; the cost of re-cabling a full switch isn't. If you're between sizes, take the bigger one — that's the one piece of gear we'll talk you into.
