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.
