Mesh Wi-Fi node count.
Enter your home size, floors and the coverage your mesh brand claims per node. The tool allows for overlap between nodes and counts nodes floor by floor.

Mesh Wi-Fi Node Count Estimator: how it works
Per floor, the tool divides the floor area by the node coverage after overlap, rounds up to a whole node (never fewer than one), then multiplies by the number of floors. Rough spacing is the side of a square with the same area as one node's effective coverage. No standard sets how much area a node covers: that number comes from the vendor's claim and your walls, so adjust it.
Worked example. A 3,000 sq ft home over 2 floors is 1,500 sq ft per floor. A node claims 1,500 sq ft; with 20% overlap its effective coverage is 1,200 sq ft. 1,500 / 1,200 = 1.25, which rounds up to 2 nodes per floor, so 4 nodes in total, spaced roughly 35 ft apart (the square root of 1,200).
Dense walls, masonry and metal reduce what a node reaches. If you are unsure, use the Wi-Fi coverage estimator to see how walls shrink the radius, then enter a smaller coverage figure here.
Frequently asked questions
How many mesh nodes do I need?
Divide each floor's area by the coverage of one node after overlap, round up, and multiply by the number of floors. A 3,000 sq ft, two-floor home with 1,500 sq ft nodes and 20% overlap needs 4.
Should I trust the coverage on the box?
Treat it as the vendor claim. Walls, floors and interference can cut it, so consider a lower figure for older or masonry homes.
Do I need one node per floor?
Often a node on each floor helps, which is why this tool counts per floor and never returns fewer than one node for each.
What overlap should I use?
This tool defaults to 20% as an assumption. There is no published standard for it; more overlap means more nodes and a more reliable link between them.
