Step 1: Determine the Number of Can Lights Needed
Before installing can lights, it’s crucial to determine how many you need. Installing too few can lead to dim spots, while too many can create excessive brightness.
The number of can lights required depends on:
- The kitchen’s size (square footage)
- Lighting needs (task lighting vs. general illumination)
- Spacing recommendations to avoid glare or dark spots
Let’s break down the process:
1.1 Measure Your Kitchen Size
How to Measure Kitchen Dimensions (Length × Width)
Before determining the number of can lights needed, you must calculate the kitchen’s square footage. The formula is:
Length × Width = Total Square Feet
For example:
- A 10 ft × 12 ft kitchen = 120 square feet
- A 15 ft × 18 ft kitchen = 270 square feet
Knowing this measurement helps apply general lighting formulas to determine the right number of can lights.
1.2 Use the General Lighting Formula
Standard Rule: One Can Light per 4-6 Square Feet
A common formula for kitchen lighting is:
Total Square Feet ÷ 4 = Minimum Number of Can Lights
Total Square Feet ÷ 6 = Maximum Number of Can Lights
Example Calculation for Small, Medium, and Large Kitchens:
- Small Kitchen (100 sq. ft.): Needs 16-25 can lights
- Medium Kitchen (200 sq. ft.): Needs 33-50 can lights
- Large Kitchen (300 sq. ft.): Needs 50-75 can lights
This range ensures sufficient brightness without over-lighting the space.
1.3 Consider Kitchen Layout & Zones
Instead of placing can lights randomly, divide the kitchen into three lighting zones:
- Task Lighting (Over Countertops & Islands) – Provides direct light for food preparation and cooking.
- Ambient Lighting (General Illumination) – Covers the entire kitchen, preventing dark spots.
- Accent Lighting (Highlighting Features) – Adds decorative lighting to highlight architectural details.
Considering these zones helps distribute light efficiently while avoiding unnecessary installations.
Step 2: Plan the Placement of Can Lights
Once you determine the number of lights needed, the next step is strategically placing them to maximize illumination.
Factors to consider:
- Spacing guidelines to prevent over-lighting or under-lighting
- Positioning lights in key workspaces
- Choosing the right beam angle for optimal brightness
2.1 Spacing Guidelines
How Far Apart Should Can Lights Be?
A general rule is:
Distance Between Can Lights = Ceiling Height ÷ 2
For example:
- An 8-foot ceiling → Can lights should be 4 feet apart
- A 10-foot ceiling → Can lights should be 5 feet apart
Avoiding Shadows & Uneven Lighting
To prevent dark areas:
Use layered lighting (pendants + recessed lights) for balance.
Place can lights closer to walls for backsplash illumination.
2.2 Positioning Can Lights for Functionality
Proper placement ensures each light serves a purpose, rather than just illuminating the ceiling. Here’s how to position can lights based on function:
Above Workspaces (Sink, Stove, Prep Areas)
- Place one can light directly above the sink to eliminate shadows.
- Position two or more can lights above countertops where food prep happens.
- Ensure stove areas have sufficient task lighting, especially if there’s no range hood with built-in lights.
Over Kitchen Islands & Dining Spaces
- Kitchen islands need at least two or three can lights, depending on size.
- Space them evenly along the length of the island.
- Combine with pendant lights for a stylish and functional look.
Around Kitchen Cabinets for Balanced Lighting
- Can lights near cabinets reduce dark corners and highlight cabinetry details.
- For upper cabinets, place can lights 12-18 inches from the cabinet face.
Proper positioning eliminates shadows, enhances visibility, and makes the kitchen more inviting.
2.3 Choosing the Right Beam Angle & Trim Type
The beam angle and trim type of can lights impact how light is distributed.
Narrow vs. Wide Beam Angle for Can Lights
