Wi-Fi Coverage Estimator
A quick planning estimate for how much Wi-Fi hardware a home this size may need. This is guidance, not an RF survey.

Rule of thumb: one good router or access point reliably covers about 1,500 sq ft on a single level. Beyond that — or through thick walls and multiple floors — you’ll want additional nodes. Use the estimator below for your home, then read on for the reasoning.
What affects coverage
- Square footage — the biggest factor.
- Walls and construction — drywall is easy; brick, concrete, and metal cut range sharply.
- Floors — signal weakens going up or down between levels.
- Device count — many simultaneous devices favour Wi-Fi 6/6E hardware.
General guidance
| Home size | Typical setup |
|---|---|
| Up to ~1,500 sq ft, one floor | Single quality router |
| 1,500–3,000 sq ft or 2 floors | 2-node mesh |
| 3,000–5,500 sq ft | 3-node mesh |
| 5,500 sq ft+ or dense walls | 3+ nodes or wired access points |
Access point vs. mesh node
A mesh node connects wirelessly and is plug-and-play — best for most homes. A wired access point connects by Ethernet and is more reliable and higher-performance, but needs cabling. If you can run Ethernet, wired backhaul is the gold standard.
