Wall-to-Wall WiFi Coverage for a House: How Many Mesh Nodes You Need One WiFi router covers about 1,500 sq ft, so a 3,000 sq ft two-story home needs 2 to 3 mesh nodes for wall-to-wall coverage: 3,000 ÷ 1,500 = 2 nodes as a baseline, rounding up to 3 once you subtract a safety margin for walls and floors. A 1,500 sq ft single-floor home usually runs fine on one router, while a 4,500 sq ft three-story house typically needs 3 to 4 nodes. Run your exact layout through the WiFi Coverage Calculator(/tools/wifi-coverage-calculator) to size it before you buy hardware. When I mapped my own 2,400 sq ft two-story house, the math said 2,400 ÷ 1,500 = 1.6, which rounds up to 2 nodes. Two nodes covered the living areas, but the far back bedroom sat behind a brick chimney that ate roughly 8 dB of signal, leaving it at...
