Home / Wi-Fi Mesh Coverage Planner
Wi-Fi Mesh Coverage Planner
Work out how many mesh Wi-Fi nodes your home actually needs based on its size, number of floors and how much your walls attenuate a signal.
How the node count is worked out
This planner divides your total floor area by a realistic coverage radius per mesh node for your construction type, then makes sure there is at least one node per floor — since a signal has to fight through more material to reach a different level than to spread across the same floor.
Coverage radius is a guideline, not a guarantee
Actual coverage depends on your router placement, interference from neighboring networks, appliances and the specific mesh hardware you choose. Treat the recommended node count as a solid starting point, and add a node to any room that tests weak once the system is installed.
Frequently asked questions
Why does construction type change the number of nodes needed?
Open-plan spaces with drywall partitions let Wi-Fi signals travel much further than homes with many interior walls, concrete floors or brick construction, which absorb and reflect radio signals. The same node can cover a much smaller usable area in a heavily-partitioned or concrete/brick home than in an open-plan one.
Should I count a basement or attic as a separate floor?
Yes, if it is a finished, regularly-used living space. Floors add both distance and additional building material between a node and the devices on other levels, which is why this tool factors floor count into node placement, not just total area.
Does more nodes always mean better Wi-Fi?
Not necessarily — too many overlapping nodes on the same channel can cause interference and actually reduce throughput. The number here is a reasonable minimum for full-home coverage; most mesh systems automatically manage channel selection between nodes to avoid this problem.
Where should each node be placed?
Spread nodes evenly across the coverage area rather than clustering them, keep each one elevated and away from metal appliances or thick walls, and place at least one node per floor so the signal does not have to travel through multiple ceilings to reach devices upstairs or downstairs.
