Measure hanging height from the tabletop to the fixture bottom. Size and center the layout from the table, not from the room ceiling.

Why this fits

Scale the light to what it illuminates.

For an island or table, the surface below is the strongest visual reference. Fixture width, spacing, and clear sightlines matter together.

Start with equal edge clearance, then confirm the actual shade diameter.

Plan room by room

Room-by-room quick guide

Build each room around the surface, furniture, or path that the light needs to serve.

Dining room

Center the light over the dining table

Let the table, not the room outline, anchor the composition so the fixture still feels intentional when the furniture is off-center.

Installation readiness

From box to final switch-on

Use this checklist before ordering and share the product-specific details with your installer.

01

Confirm the fixture

Check overall dimensions, canopy, voltage, bulb base, maximum wattage, dimmer compatibility, cord or rod length, and sloped-ceiling compatibility.

02

Check the location

Verify junction-box support, fixture weight, walking and furniture clearances, and dry, damp, or wet location listing for the exact position.

03

Prepare the installer

Share the product page, wiring diagram, ceiling material, circuit details, desired drop, and final mounting marks before installation day.

04

Inspect and test

Confirm level, secure mounting, clearances, bulb wattage, switching, dimming, and that no cord or hardware is under strain.

Safety first: Hardwired fixtures should be installed by a qualified electrician in accordance with the product instructions and local electrical code. Turn power off at the breaker and verify it is off before electrical work. Product-specific ratings always take precedence over general guidance.

Common questions

Before you order

General guidance helps narrow the choice. Always confirm the exact product before installation.

How large should my chandelier be?

For an open room, add the room length and width in feet and use that number as an approximate fixture diameter in inches. Over a table, start around 50-67% of a rectangular table's length or a round table's diameter.

How low should pendants hang over a kitchen island?

A common starting range is 30-36 inches from the countertop to the bottom of the pendant. Adjust for sightlines, fixture shape, and household height.

How many pendants should I use over an island?

Compare a linear fixture, two pendants, and three pendants for the island's actual dimensions. The planner checks common 12, 16, and 20 inch shade families; actual shade diameter, equal end clearance, and measured shade-edge spacing determine which layouts fit.

Can I use a chandelier with an 8-foot ceiling?

Use a compact chandelier only when it preserves at least 7 feet of walking clearance. A flush or semi-flush fixture is usually a more practical starting point.

What color temperature works best at home?

2700-3000K usually feels comfortable in living, dining, and sleeping areas. Kitchens, bathrooms, and offices often benefit from 3000-3500K.

Can every pendant be installed on a sloped ceiling?

No. Check the specific product canopy, cord or rod system, permitted angle, and installation instructions before ordering.

Do I need a qualified electrician?

Hardwired fixtures should be installed by a qualified electrician in accordance with the product instructions and local electrical code.
