If you have ever stretched an extension cord across a room because the nearest outlet was too far away, you have run into exactly the problem the electrical code was written to prevent. The required distance between outlets is governed by the National Electrical Code (NEC), and the core idea is simple: no spot along a usable wall should be more than 6 feet from a receptacle. That works out to outlets spaced no more than 12 feet apart. Here is how the rule works and where it gets tighter.

The 6-Foot / 12-Foot Rule
The foundation of outlet spacing in living areas is often called the “6/12 rule.” The NEC requires that no point measured horizontally along the floor line of a wall be more than 6 feet from a receptacle. Because a receptacle reaches 6 feet in each direction, this means general-purpose outlets land at most 12 feet apart.
The logic is to keep a lamp, charger, or appliance cord within easy reach of an outlet without relying on extension cords. When you space outlets 12 feet apart, any point between them is within that 6-foot reach.
Which Walls Count
The spacing rule applies to “wall space” in habitable rooms such as bedrooms, living rooms, dens, and similar spaces. Any wall section 2 feet wide or wider is considered usable wall space and must have a receptacle. That includes wall space broken up by doorways, fireplaces, and similar features.
Short wall segments under 2 feet wide do not require their own outlet. Fixed glass panels, sliding door panels, and similar non-wall surfaces are generally not counted as wall space for this purpose. The goal is that any normal place you would set furniture has an outlet within reach.
Why the Rule Exists
Outlet spacing is a safety standard, not just a convenience. When outlets are too far apart, people reach for extension cords and power strips, which are a common cause of overloaded circuits and electrical fires when used as permanent wiring. Properly spaced receptacles reduce that temptation.
Code minimums are exactly that, minimums. Many homeowners and electricians add more outlets than the code requires, especially in rooms full of electronics, because there is no penalty for having outlets closer together than the maximum.
Kitchen and Countertop Rules Are Tighter
Kitchens have stricter spacing because of the number of appliances used there. Along a kitchen countertop, no point is allowed to be more than 24 inches from a receptacle, meaning counter outlets sit no more than 4 feet apart. Any countertop section 12 inches wide or wider generally needs a receptacle.
These countertop circuits also have their own requirements, including dedicated small-appliance circuits and ground-fault (GFCI) protection. Bathrooms, garages, outdoor areas, and other locations near water carry additional GFCI rules as well.
Other Spaces With Specific Requirements
Beyond living areas and kitchens, several spaces have their own outlet rules:
- Hallways: a hallway 10 feet or longer typically requires at least one receptacle.
- Bathrooms: at least one GFCI-protected receptacle within 3 feet of the outside edge of each sink basin.
- Garages and basements: require receptacles, with GFCI protection in many locations.
- Outdoor areas: require accessible, GFCI-protected, weather-resistant receptacles.
Local amendments can modify any of these, so always confirm the rules adopted in your jurisdiction.
Mounting Height and Layout Tips
While the code focuses on horizontal spacing, standard practice puts general wall outlets roughly 12 to 16 inches above the floor (measured to the box), and countertop outlets above the backsplash. Consistent heights look cleaner and make furniture placement predictable.
When planning a remodel, think about where furniture and electronics will actually go. Putting an outlet behind where a TV or desk will sit saves you from visible cords later. There is no downside to exceeding the minimum count.
Safety and When to Call a Pro
Anytime you work on receptacles, turn off the breaker for that circuit and verify the wires are dead with a voltage tester before touching anything. Electricity is unforgiving, and a “dead” outlet can still be live if you flip the wrong breaker.
Adding or moving outlets, running new circuits, and any work behind walls often requires a permit and inspection, and in many cases a licensed electrician. If you are not completely confident, hire a professional. Understanding the distance between outlets helps you plan a comfortable, code-compliant room, but the actual wiring is one area where doing it right and safely matters more than doing it yourself.
Floor Outlets and Large Open Rooms
The 6-foot rule applies to wall space, which creates a gap in big open-concept rooms where furniture floats far from any wall. To serve a sofa or table in the middle of a large room, electricians often install floor outlets, which count toward keeping a usable area within reach of power. These require special boxes and covers rated for floor use.
Fixed room dividers, certain railings, and freestanding counters can also be treated as wall space under the code in some situations. If you are planning a great room or finishing a basement, think early about where seating and electronics will land so you can add floor or peninsula outlets before the finishes go in.
Planning Outlets During a Remodel
A remodel is the ideal time to exceed the minimums, because adding outlets while walls are open is cheap and easy, while adding them later means cutting into finished surfaces. Walk through each room imagining daily life: where lamps, chargers, a vacuum, holiday decorations, and electronics will plug in, then place outlets accordingly.
Common smart additions include outlets near the bed for chargers, a receptacle behind where a wall-mounted TV will hang, exterior outlets for tools and lights, and extra kitchen-counter receptacles. Discuss your plan with your electrician so the layout meets code and your real-world needs at the same time. Spending a little more on outlets now is one of the cheapest upgrades you can make.
Spacing Versus Circuit Capacity
It is worth understanding that outlet spacing and circuit capacity are two separate concerns. The 6/12 rule governs how far apart receptacles can be, but it says nothing about how many devices a single circuit can safely power. You can have perfectly spaced outlets that all share one overloaded circuit, which trips breakers and is unsafe.
A typical general-purpose circuit serves several outlets, but high-draw areas, kitchens, laundry, garages, and home offices full of equipment, often need dedicated circuits. When planning, think about both reach (spacing) and load (how many amps the connected devices draw). An electrician balances both so you have convenient access to power and the wiring to support it.
