What diameter your chandelier should be

The rule we use in the workshop: add the length and width of the room in metres, multiply by 10, and you have the chandelier's diameter in centimetres. For a room of 5 × 4 metres: 5 + 4 = 9, so a diameter of about 90 cm. It is a convention of proportion, not a law — it works for rooms with an ordinary ceiling, between 2.5 and 3 metres. Above that height, the silhouette of the piece matters more than its diameter.

The sizing table

The number of pieces and the number of arms in the table are read straight from our catalogue, at the moment you open the page.

Room (L + W) Diameter Suits Usual arms In the catalogue
3 + 3 m sub 40 cm Hol, baie, debara, nisa around 2 62 pieces
4 + 4 m 40 - 60 cm Dormitor, birou, bucatarie around 5 104 pieces
6 + 5 m 60 - 80 cm Living mediu, sufragerie around 10 89 pieces
7 + 6 m 80 - 100 cm Living mare, casa scarii around 12 95 pieces
8 + 7 m 100 - 140 cm Hol de receptie, restaurant around 20 111 pieces
peste 14 m peste 140 cm Sala de evenimente, atrium, lacas de cult around 59 63 pieces

What height to hang it at

  • Above a table — the bottom edge of the chandelier sits 70-85 cm above the tabletop. Low enough to light the plates, high enough not to cut the line of sight between people at the table.
  • In a circulation area — at least 210 cm from the floor to the lowest point of the piece. Below that, a chandelier becomes an obstacle.
  • In a stairwell — the piece is read from several levels, so what matters is the overall height, not the diameter. See the guide for staircases.
  • High ceiling — above 3.5 m, choose a piece with several tiers: it gains volume vertically without growing in diameter.

Three common mistakes

  • Too small a piece. The most common one. A chandelier under-sized for the room looks lost and does not light it evenly. If you are torn between two diameters, take the larger.
  • Measuring by the table, not the room. Above a table, the chandelier's diameter is taken at about half the width of the tabletop — not from the room rule.
  • Ignoring the ceiling. A 2.4 m ceiling calls for a compact piece with a low profile. The same piece that looks commanding at 3.5 m becomes an obstacle at 2.4 m.

Every piece can be made in a size other than the catalogue one — diameter, height and number of arms are adapted to the room.See all the chandeliers · Ask for a made-to-measure size
