Room-by-room starting points for fixture size, hanging height, spacing, and clearance.

Room-by-room guide

Choose a space.

Select the setup closest to your room and jump directly to its measurements and placement checks.

01

Dining table

Size and centre the fixture from the tabletop, then confirm the view from every seat.

How to measure
Measure the table's length and width. For a round table, use its diameter.
Starting range
A round fixture often feels balanced at about one-half to two-thirds of the table width. A linear fixture can begin at one-half to two-thirds of the table length.
Placement
Centre the light over the table, not necessarily the room. Keep the fixture within the table footprint and visually clear of seated sight lines.
Clearance
Start 76–91 cm above the tabletop. With ceilings above 2.44 m, raise the fixture only as needed to keep the room open and the light connected to the table.
For a long tableTwo smaller pendants may read more naturally than one oversized fixture.

Lay out the centres evenly along the table and keep the outer fixtures comfortably inside the table ends.

Before drilling

Tape a paper outline to the ceiling or suspend a lightweight template at the planned height. Check it from the doorway and from a seated position.

02

Kitchen island

Coordinate fixture width, quantity, and centre spacing across the usable island surface.

How to measure
Measure the usable island length and width, excluding overhangs that do not need task light. Note where people stand and where stools are placed.
Starting range
For a single linear fixture, begin at one-half to two-thirds of the island length. For multiple pendants, choose a modest diameter before deciding how many fit.
Placement
Keep pendant centres evenly spaced on the island centreline. Map equal centres across the usable run, then confirm that adjacent shades retain comfortable breathing room.
Clearance
Start 76–91 cm above the worktop. Preserve an open view across the island and keep the outer pendants in from the island ends.
Quantity checkChoose the count only after the fixture width is known.

More fixtures require smaller shades and closer coordination. Fewer fixtures can be larger, but should not crowd the ends of the island.

Lucia note

Mock up the full row, not just one pendant. Three paper circles taped above the island reveal spacing problems much faster than a single sample.

03

Room centre

Estimate fixture width from the room dimensions, then check visual weight and walking clearance.

How to measure
Measure room length and width in metres, plus finished ceiling height. Note doors, tall furniture, and the main walking path.
Starting range
Add room length and width in metres, then multiply the total by 8.33 to estimate a starting diameter in centimetres. For example, a 3.6 m by 3 m room suggests about 55 cm.
Placement
Use the architectural centre only when it also makes sense from the doorway and furniture plan. A seating arrangement may call for a visual centre instead.
Clearance
Maintain at least 2.13 m of clear height below the lowest point in an open walking area. Low ceilings usually favour flush or compact semi-flush forms.
Visual-weight checkOpen forms can feel lighter; dark or dense shades can feel larger.

Compare one size smaller and one size larger in the room before treating the formula as final.

Before drilling

Ask a qualified electrician to confirm that the ceiling structure, fixings and electrical connections suit the fitting. Heavy fittings may require additional support.

The room formula sets a starting diameter; ceiling height and visual weight finish the decision.

04

Hallway and entry

Set fixture count from spacing, then keep equal end offsets and a clear walking path.

How to measure
Measure the clear corridor length and width. Mark door swings, openings, stairs, and any point where the ceiling changes.
Starting range
In a narrow passage, begin by testing compact fixtures about 1.83–2.44 m on centre, then adjust for ceiling height, beam spread, and light output. Wider entries can support one larger fixture or a more closely spaced rhythm.
Placement
Align fixtures on the path centreline. Start the first and last fixture at roughly half the centre-to-centre spacing from the corridor ends.
Clearance
Keep at least 2.13 m below the lowest point and make sure open doors, tall cabinets, and stair sight lines remain clear.
For unusually long hallsDecide the fixture count from spacing - not from a single oversized diameter.

Once a count is chosen, divide the usable run into equal bays and check the end offsets before wiring.

Lucia note

A dimmer can make repeated fixtures more adaptable across daytime, evening, and overnight use.

05

Bathroom vanity

Place light for even facial illumination while keeping mirrors, cabinets, and wet locations clear.

How to measure
Measure mirror width, mirror height, vanity width, and the available wall area on both sides. Note the sink centreline.
Starting range
For paired sconces, aim for the visible centre of each sconce at about 165–178 cm above the finished floor (AFF), then adjust for fixture shape, mirror height, and the primary user's eye level. For an over-mirror bar, begin around three-quarters of the mirror width.
Placement
Place paired sconces symmetrically on both sides of the mirror. Keep the nearest edge of each fixture about 8–15 cm from the mirror edge where the product shape allows, while keeping the light source near face level.
Clearance
Confirm mirror edges, medicine-cabinet swing, taps, and adjacent doors. Choose an IP rating suitable for the bathroom zone and ask a qualified electrician to confirm the requirements of BS 7671.
Most even resultSide lighting usually softens facial shadows better than a single light overhead.

If side wall space is limited, choose a wide over-mirror fixture with a diffused shade.

Before drilling

Hold the sconce at the proposed height while someone checks the reflection. Shift it before wiring if the bulb or bright edge is directly visible in the mirror.

06

Bedroom and bedside

Set the light from the seated position and keep the switch, shade, and brightest source easy to use.

How to measure
Record mattress-top height, bedside table height and width, headboard height, and the seated shoulder or eye level of the main user.
Starting range
For a table lamp, aim to bring the bottom of the shade close to seated shoulder level. Keep the shade comfortably within the bedside table width.
Placement
Place a wall sconce or pendant where its light falls across the book or bedside surface without shining directly into the user's eyes.
Clearance
Keep swing arms, shades, and cords clear of pillows and head movement. Confirm the switch can be reached from bed without stretching.
Pairing checkMatch the light source height before matching the fixture shape.

Two different bedside table heights may require adjustable lamps or independently set wall lights.

Lucia note

Test the light while seated in bed. A placement that looks balanced from the doorway can still create glare at pillow height.

Reading and living

Position the lamp beside or behind the reader so the page is lit without direct glare.

How to measure
Measure seat height, arm height, and the distance from the chair or sofa to the proposed lamp position. Sit in the actual reading posture.
Starting range
For a floor lamp, begin with the bottom of the shade near seated eye level. For a table lamp, use a table height that places the light above the shoulder and beside the page.
Placement
Place the lamp slightly behind or beside the reader's shoulder so the light reaches the page without casting a strong hand shadow.
Clearance
Keep the base out of the walking path and cords away from chair movement. Confirm that adjustable arms do not swing into nearby furniture.
Comfort checkThe bulb and brightest part of the shade should not be visible at seated eye level.

If glare remains, lower the lamp, choose a deeper shade, or use a more diffused light source.

Lucia note

Test the reading light with the room's other lights on and off. A dimmable source makes it easier to balance task light with evening ambience.

Before installation

Final installation checklist.

Use the recommendation as a starting point, then confirm the final layout on site.

01Fit

Check the fixture from the main viewpoints and keep doors, cabinets, furniture, and walking paths clear.

02Support

Confirm the fitting weight, ceiling structure, suitable fixings and electrical connections with a qualified electrician.

03Code

Follow the product instructions and BS 7671. For bathrooms, confirm the installation zone, IP rating and required electrical protection with a qualified electrician.
