The correct switch height on a bedside lamp determines whether you can comfortably turn the light on and off in bed. Equally important is whether the lamp provides enough brightness for reading without disturbing your partner. Many buyers only realize after assembly that the switch is too low or the light distribution is unfavorable. This guide shows which dimensions and technical values you should check before purchasing so that your bedside lamp and bed are optimally matched.
The Ideal Switch Height Above the Mattress
The switch should be located between 40 and 60 cm above the top edge of the mattress. At this height, you can reach it while lying down with your arm extended, without having to sit up. To do this, measure the height of your mattress top edge from the floor and add 40 to 60 cm. The result is the height at which the switch should be located on the lamp. For a box spring bed with a total height of 65 cm, the switch would then be between 105 and 125 cm above the floor. For a low bed frame with a height of 50 cm, it would accordingly be between 90 and 110 cm.
Many table lamps have the switch on the base or on the cable. If the lamp is on a bedside table with a height of 55 cm, a base switch will be about 60 cm above the floor. This is significantly below the top edge of the mattress and forces you to bend down. Therefore, choose lamps with a switch on the shade or socket if the bedside table is lower than the mattress.
Matching Lamp Height and Bedside Table Height
The total height of the lamp determines where the light source is located. For reading light, the lower edge of the shade should be approximately at shoulder height when you sit upright in bed. This usually corresponds to 80 to 100 cm above the mattress. Add these 80 to 100 cm to the height of the bedside table to determine the required lamp height.
A bedside table with a height of 60 cm therefore requires a lamp with a total height of 140 to 160 cm, measured from the floor. If the bedside table is only 50 cm high, you need a lamp of 130 to 150 cm. If you already have a bedside table, measure its height and add the desired position of the light source. This way, you avoid the shade ending up too high above your head or too low next to your hip.
Light Output and Color Temperature for Reading
For reading, you need an illuminance of at least 300 lux on the book page. A lamp with 400 to 600 lumens of luminous flux achieves this value if the distance between the light source and the book is about 50 to 70 cm. Check the lumen specification in the product description or on the light source. LED lamps with 6 to 8 watts usually provide 470 to 600 lumens.
The color temperature should be between 2700 and 3000 Kelvin. This warm white range allows for relaxed reading without inhibiting melatonin production too much. Cool white light sources above 4000 Kelvin have an activating effect and make it harder to fall asleep. Make sure that the shade directs the light downwards and sideways, not upwards towards the ceiling. This keeps the brightness concentrated on your side of the bed.
Shade Shape and Light Distribution
A conical or cylindrical shade with a closed top directs the light specifically downwards. This shape is suitable for reading because it casts a bright cone of light on the book and bedside table. Open shades or spherical lamps scatter light in all directions and are more likely to glare your partner. The shade diameter should be between 20 and 35 cm so that enough area is illuminated without the lamp appearing too bulky.
Fabric shades dampen the light more strongly than metal or glass shades. Choose light interiors, such as white or cream, to minimize reflection losses. Dark interiors absorb up to 40 percent of the light. If you read frequently, prefer shades with a metal reflector or light textile lining.
Guidelines for Dimensions and Performance

| Switch height above mattress | 40 to 60 cm |
| Bottom edge of shade above mattress | 80 to 100 cm |
| Luminous flux for reading | 400 to 600 lumens |
| Color temperature | 2700 to 3000 Kelvin |
| Shade diameter | 20 to 35 cm |
| Illuminance on book page | at least 300 lux |
Practical Tips for Selection
- Measure the height of your bedside table and the top edge of the mattress before ordering a lamp.
- Check whether the switch is on the shade, the socket, or the base, and calculate its position relative to the mattress height.
- Choose dimmable light sources if you want to adjust the brightness for different activities.
- Ensure a stable base with a diameter of at least 15 cm so that the lamp does not tip over when you operate the switch.
- Prefer lamps with an adjustable arm or shade to direct the light cone as needed.

Frequently Asked Questions
What should be the total height of a bedside lamp?
The total height depends on the height of the bedside table. The lower edge of the shade should be 80 to 100 cm above the mattress. For a bedside table with a height of 60 cm and a mattress at 65 cm height, the lamp height would be approximately 145 to 165 cm from the floor. Measure your bedside table and add the desired height above the mattress.
Is a lamp with 400 lumens sufficient for reading?
Yes, if the distance between the light source and the book is 50 to 70 cm. A lamp with 400 lumens produces about 300 lux on the book page at this distance, which is sufficient for relaxed reading. For longer reading sessions or if your eyesight is declining, choose 500 to 600 lumens.
Where should the switch on a bedside lamp be located?
The switch should be 40 to 60 cm above the top edge of the mattress so you can reach it while lying down. Lamps with a switch on the shade or socket are more favorable than those with a base switch if the bedside table is lower than the mattress. Measure the height of your mattress and check where the switch is positioned on the lamp.
What color temperature is suitable for bedside lamps?
Warm white light between 2700 and 3000 Kelvin is best. This color temperature allows for reading without fatigue and disturbs melatonin production less than cool white light. Light sources above 4000 Kelvin have an activating effect and can delay falling asleep.
