You just moved into a bigger place, or maybe you've lived there for years and finally noticed the Wi-Fi dies the second you walk into the bedroom at the far end of the hall. The router that worked fine in your old apartment doesn't work here. That's not a coincidence. Router range and home size have to match, and most people buy based on price or whatever their internet provider handed them, not square footage.
Here's how to actually pick the right one.
Start with square footage, not marketing claims
Router boxes print "covers up to 3,000 sq ft" in big letters. That number assumes an open floor plan with no walls, no metal appliances, and no neighbors' networks fighting for the same channels. Real homes aren't like that. A router rated for 2,000 sq ft might only deliver solid coverage across 1,200 sq ft once you account for walls and floors.
A rough starting point: a single router works fine for apartments and homes under 1,500 sq ft with an open layout. Homes between 1,500 and 3,000 sq ft usually need a stronger router placed centrally or a two-piece mesh system. Anything over 3,000 sq ft, multiple floors, or a layout with lots of walls almost always needs a mesh system with three or more nodes.
Multiple floors change everything
Wi-Fi signal loses strength going through floors more than it loses strength going through most interior walls. A router in a basement office with a bedroom two floors up can leave that room with a weak signal no matter how strong the router is. For multi-floor homes, coverage matters more than raw power. A mesh system with one node per floor solves this in a way a single router usually can't.
What actually blocks Wi-Fi in your house
Brick, concrete, and plaster walls block signal harder than drywall. Mirrors and large metal appliances like refrigerators and big TVs create dead zones behind them. Fish tanks are surprisingly bad, water absorbs Wi-Fi signal. If your home has any of these between your router and the rooms you use most, budget for stronger coverage than the square footage alone would suggest.
Mesh solves range, not always speed
Mesh systems like Eero, Google Nest Wifi, and Orbi spread multiple nodes around the house so you're never far from a signal source. They're the right call for anything larger than a small apartment. But mesh doesn't automatically mean faster internet, it means more consistent coverage. If your base internet plan is slow, a mesh system spreads that same slow speed everywhere instead of fixing it.
Wi-Fi 6 is worth it if you have a lot of devices
Wi-Fi 6 routers handle more connected devices at once without slowing down, which matters more in a smart home with a dozen connected gadgets than in a house with just a couple of phones and a laptop. If you've got a fair number of connected devices, the upgrade is worth the cost. If you're mostly just streaming and browsing, older Wi-Fi 5 gear still gets the job done.
The setup mistake that undoes a good router
Even the right router in the wrong spot performs badly. Central placement, away from thick walls and metal appliances, elevated off the floor, beats a pricier router shoved in a closet in the corner of the house. Before buying an upgrade, try moving your current router to a more central spot and see how much that alone changes things.
When it's time to get help
Figuring out square footage, wall materials, floor count, and device count all at once is a lot to work out on your own, especially while five router brands make five different claims.

Frequently Asked Questions
How many square feet does one router actually cover?
Manufacturer numbers are best case scenarios. In a real home with walls and furniture, cut the advertised coverage by roughly a third to get a realistic number.
Do I need mesh Wi-Fi for a two-story house?
Depends on where your router sits and how far the signal has to travel vertically. A router on the main floor near the stairs often covers a modest two-story home fine. Larger homes usually do better with mesh.
Can I just add a Wi-Fi extender instead of buying a mesh system?
Extenders help in a pinch but they rebroadcast a weaker version of your signal and can cut your speed in half at the extended range. Mesh systems use a dedicated connection between nodes and hold speed better across the house.
