Under a large mosque dome, the chandelier is the most visible element of the interior, and the wrong size is one of the hardest mistakes to fix later. A chandelier that is too small disappears beneath the dome; one that is too large or hung too low overwhelms the dome and cuts across the congregation's view of the mihrab. In this article we explain how a mosque chandelier is sized for a large dome, using Yön Avize's Al Hassan Mosque project in Bahrain as the example. The ratios and recommendations below are general guidance; the exact size for each mosque is worked out from its own architecture.
Al Hassan Mosque: an 8-metre main chandelier
Yön Avize designed, manufactured and installed the chandeliers for Al Hassan Mosque, built by Mohammed bin Yousef Al-Hassan, owner of Al Hassan Holding, in his hometown of Busaiteen (Muharraq, Bahrain). The project includes an 8-metre-diameter main chandelier, more than 20 large chandeliers and dozens of wall sconces. At this scale the main chandelier is never sized on its own: the main chandelier, the secondary chandeliers and the sconces are planned in one design language and in proportion to each other.

1. The chandelier is centred on the dome
The main chandelier under a dome hangs on the same axis as the dome's centre, so its rings are concentric with the dome. Because the rings are arranged around the vertical axis that drops from the crown, the chandelier repeats the dome's geometry when seen from below: the dome decoration, the drum windows and the rings read as a single composition. Before measuring, the true centre of the dome and the hanging point at the crown should be confirmed. For large chandeliers, the load capacity of the hanging point should be checked with the project's structural engineer.
2. Diameter is chosen relative to the dome
A common starting point for the main chandelier's diameter is roughly one third to one half of the dome's inner diameter. This is a starting range, not a rule, and several factors can push it up or down:
- Dome height: In a tall, deep dome the chandelier hangs further down, so a wider diameter does not look out of proportion.
- Drum and windows: The chandelier should not block daylight from the drum windows or visually cut the row of windows.
- Dome decoration: If the dome carries painted ornament or calligraphy bands, the chandelier should not hide them when seen from below.
- Prayer hall width: If the areas outside the dome will be lit by secondary chandeliers, the main chandelier is sized for the dome alone.
The basic information needed for sizing: the dome's inner diameter, height from floor to crown, drum height, prayer hall dimensions and, if possible, a section drawing of the mosque.
3. Hanging height: from the prayer floor to the lowest ring
How low the chandelier hangs matters as much as its diameter. The general approach is to keep the lowest ring comfortably above the heads of standing worshippers and clear of the line of sight from the rows to the mihrab. A chandelier hung too high struggles to bring light down to the prayer floor and gets lost inside the dome; one hung too low makes the space feel smaller. The most reliable way to find the balance is to place the chandelier in 3D on the mosque's section drawing or interior photo and try it at different heights. Access to the lowest point for maintenance and cleaning should also be planned.
4. Ring tiers: what "300 3+1" means
Large mosque chandeliers are usually built from concentric rings, or tiers. In the naming we use on our site, a "300 3+1" chandelier has three rings of 3 m, 2 m and 1 m diameter plus a small pendant lamp of about 30 cm at the bottom. Medium domes usually take a 2+1 arrangement and large domes a 3+1 or 4+1; very large domes get a custom tier arrangement. More tiers fill the depth of the dome better and spread light across different heights.
5. Lamp count and light
The number of lamps on each ring grows with its diameter. Yön Avize's standard is 10 lamps per metre of ring diameter, with the pendant lamp adding one more. A "300 3+1" chandelier therefore has 30 + 20 + 10 + 1 = 61 light points. The lamp type (oil-lamp style, lantern or LED) and colour temperature are chosen according to how much daylight the mosque receives, the interior colours, and whether verse or motif bands will be backlit.
6. Plan the whole prayer hall, not just the main chandelier
In a large mosque the main chandelier under the dome does not light the whole prayer hall by itself. Side domes, galleries and areas outside the dome are completed with secondary chandeliers, and the walls with sconces. At Al Hassan Mosque, more than 20 large chandeliers and dozens of sconces were made in the same design language as the main chandelier. In this approach the secondary chandeliers are scaled down to suit the main chandelier and their own ceiling height, while motifs, materials and light colour stay consistent, so the prayer hall reads as one lighting scheme rather than a collection of unrelated fixtures.
7. Manufacturing, shipping and installing a large chandelier
A chandelier of 8 metres cannot travel in one piece. Chandeliers at this scale are made in sections, packed as numbered parts and assembled on site. Working under the dome requires scaffolding, a suspension detail agreed in advance, and electrical connections planned around the installation schedule. On projects abroad, Yön Avize installs with its own team.
Frequently asked questions
What if we don't know the dome diameter? Without architectural drawings, the distance between two opposite sides of the dome can be measured at drum level; we can plan together how to take the measurement.
Can you design the chandelier without visiting the mosque? Yes. We prepare the 3D design from architectural drawings, measurements and photos; for large projects a site visit can be arranged when needed.
Does a large chandelier arrive in one piece? No. Large chandeliers are shipped in numbered parts and assembled on site.
What to send us for mosque chandelier sizing
- Dome inner diameter and height from floor to crown
- Drum height and window layout
- Prayer hall dimensions, plus side domes or galleries if any
- An architectural section drawing or interior photos
With this information we design the chandelier in 3D inside your mosque and submit the diameter, tier arrangement and hanging height for your approval; production starts only after approval.
