The quick answer

Each light should be one-quarter to one-third of your door height, centered 66 to 72 inches above the ground.

Follow that one rule and most ‘too small’ porch lighting problems disappear. This guide gives you the numbers for front doors, garages and patios, plus how to match a fixture to the weather it will face.

1/4–1/3

Quick sizing and height chart

Location	Fixture size	Mounting height (center)	Placement
Front door, pair	1/4 to 1/3 of door height	66 to 72 in	6 to 12 in outside the frame, one each side
Front door, single	About 1/3 of door height, or larger	66 to 72 in	On the handle side of the door
Garage door	Same rule, from the garage door height	Same as the rest of the facade	One at each end, or one long bar above
Patio or deck door	Same rule, from the nearest door	66 to 72 in	Beside the door, matching the front entry

These are widely used design guidelines, not code requirements. Your fixture’s installation instructions and local electrical code always come first.

Step 1: Measure your door

Measure the door from the floor to the top of the trim. Divide that number by 4 and by 3 to get your size range.

Example: a standard 80-inch door gives 20 inches (1/4) to about 27 inches (1/3). A fixture between 20 and 27 inches tall will look balanced.

When in doubt, size up. Your lights are seen from the street and from the car with the whole facade behind them, so they read smaller than they do in your hand. Double doors and tall entrances call for larger fixtures still.

Pro tip: cut a piece of cardboard to the fixture’s dimensions and tape it beside the door. Walk to the curb and look at it. Two minutes of checking prevents most returns.

Step 2: Set the mounting height

Mount each fixture so its center sits about 66 to 72 inches above the ground or porch floor. Taller households can lean toward 72. For very tall fixtures, also check that the bottom edge stays above head height.

Use the same height on every light across the front of the house. Mismatched heights are what make an exterior look unplanned.

Step 3: Place the pair around the door

Hang matching lights 6 to 12 inches outside the door frame, one on each side. That frames the door without crowding it.

If the wall only has room on one side, mount a single light on the handle side. A single fixture can be larger than one of a pair, at about one-third of the door height or more.

Step 4: Handle the garage and patio doors

For a garage, apply the same fraction to the garage door’s height. Most homes look best with one light at each end of the door, or one long linear bar centered above it.

For a patio or deck door, measure the nearest door and match the style of your front entry. Consistent finishes and color temperature make the whole house read as one design.

Step 5: Match the weather rating to the location

A fixture has to be rated for the exposure it will see.

IP54 / damp-rated

Covered porches and sheltered walls. Protected from splashing, but not meant for direct rain, snow or sun.

IP65 / wet-rated

Open walls, uncovered doors and garage fronts. Rated against water jets, so it handles direct rain.

At SCI Lighting, the Vega up-down wall light and the Onda up-down wall light are IP54, which suits covered porches. The Axis, Linea, Lintel and Vesper are IP65 for fully exposed walls.

Step 6: Pick a shape that fits your wall

Bars, up-down lights and lanterns scale differently, so apply the door rule to the right dimension.

Vertical sconces and lanterns: use height. The 1/4 to 1/3 rule applies directly.
Horizontal bars above a door: use width. A bar about one-quarter to one-third of the door frame’s width looks proportional. On a 36-inch door that is 9 to 12 inches, in the range of the mid-size Lintel linear porch light options.
Long bars along a wall: slim lines like Linea, which runs from 24 to 60 inches, work as an architectural line across a facade, fence or garage front.
Up-down lights: throw light above and below the fixture, which gives a flat wall real depth after dark. Choose the largest size for the main entry and the smaller ones for secondary spots.

Three mistakes to avoid

Buying too small. This is the most common error. When two sizes look close, take the bigger one.
Mounting at different heights. Pick one height and hold it across the whole front elevation.
Mixing finishes and color temperatures. Match them across every light you can see from the street.
