Especially when it comes to the selection of lighting fixtures, how to match lighting fixtures of appropriate sizes according to space size and functional requirements is the focus of many consumers. This article combines popular discussions in the past 10 days to provide you with a structured guide to help you easily solve the problem of lighting selection.

restaurant12-20 (chandelier diameter)2.4-3.0
kitchen12-18 (multi-light combination)2.2-2.6

2. Practical skills in popular discussions

1.calculation formula method: The formula "(length + width) ÷ 12 = lamp diameter (inches)" that has been widely circulated on social platforms recently is suitable for square or rectangular spaces. For example, for a living room of 5 meters by 4 meters, it is recommended to use about 30-inch lamps.

2.Floor height adaptation solution: The experience post shared by a Xiaohongshu user "For every 0.5 meter increase in floor height, the height of the lamp can be increased by 10-15cm" received over 20,000 likes. Specific reference is as follows:

Floor height rangeChandelier sagging advice
2.4-2.7 meters30-50cm
2.8-3.2 meters60-100cm
3.3 meters or moremulti-level chandelier

3. Specific selection suggestions for different spaces

1.Living room main light: Zhihu Hot Post recommends that the width of the lamp should be less than 1/3 of the length of the short side of the room. For example, in a 3-meter-wide living room, the diameter of the main light should not exceed 1 meter.

2.dining table chandelier: It is mentioned in the hot topic on Weibo #Restaurant Lighting Design that the diameter of the chandelier should be 30-40cm smaller than the width of the dining table, and the hanging height should be 70-90cm from the tabletop.

3.bedroom ceiling lamp: Measured data from Douyin home decoration bloggers shows that ceiling lamps with a diameter of 40-50cm are suitable for bedrooms with a size of 12-15㎡, as the illumination is more uniform.

4. New trends in lamp size in 2023

5. Guide to avoid pitfalls

1. Avoid being "top-heavy": The size of the lighting fixtures should be coordinated with the proportions of the furniture. For example, a small coffee table paired with a large chandelier will look awkward.

2. Pay attention to the load-bearing capacity of the installation: A recent "gypsum board ceiling lamp falling" incident exposed on a home furnishing forum reminds that lamps exceeding 5kg need to be reinforced separately.

3. Consider the difficulty of cleaning: Although oversized crystal lamps are beautiful, their cleaning costs are high, which has become a hot topic in Xiaohongshu recently.

Through the integration of the above structured data and hot content, I believe you can choose the lighting size suitable for the space more scientifically. Remember, good lighting design must not only meet functional needs, but also be harmonious and unified with the overall home style.
