Pendant Light Drop Height Calculator
Hang a pendant light too high and it fails to light the table properly, but hang it too low and it blocks sightlines or dazzles anyone seated nearby. Enter your ceiling height and the surface height below to get a recommended cord or chain drop length.
Work out the right pendant light drop
Enter your ceiling height and the height of the surface below to get a recommended cord or chain length.
For a pendant hanging 70-80cm above that surface, set the cord or chain drop to:
90cm
This keeps the bottom of the shade at a comfortable height without glaring into eyes or blocking sightlines across the table.

Frequently asked questions
How far above a dining table should a pendant light hang?
A common rule is to hang the bottom of the pendant around 70-80cm above the table surface, which lights the table well without the fitting getting in the way of sightlines across it.
Does this rule change for very high or low ceilings?
Yes, with a very high ceiling you can hang the pendant slightly higher than 80cm above the table for a more proportional look, while in a room with a low ceiling you may want to stay closer to 70cm so the light still feels close enough to the table.
Should I measure the drop from the ceiling or from the fitting itself?
The drop length is the cord or chain between the ceiling rose and the top of the light fitting, so you will also need to account for the height of the shade itself when checking the final height above the table.
Can I use the same rule for a kitchen island or breakfast bar?
Yes, the same 70-80cm-above-the-surface guideline works well for kitchen islands and breakfast bars, though you may want to hang the pendant slightly higher if it sits directly in your eyeline while seated.
How this Calculator Works
This calculator uses a straightforward formula to determine the necessary cord length. It begins with your desired tabletop height above floor level, which you enter in centimetres. Then, it calculates the optimal chain length based on a standard table width of 90cm – a common size for dining tables and countertops. The calculation takes into account an allowance for the light fixture’s shade diameter, typically around 15cm to 20cm, ensuring sufficient clearance between the bulb and the tabletop.
The result is presented as a chain length in centimetres. This provides you with a practical guide for selecting a pendant light with the appropriate cord or chain. Remember that this calculation assumes standard table dimensions and doesn't account for unusual fixture designs or specific aesthetic preferences; adjustments might be needed based on your individual requirements.
Chain Length Recommendations – UK Standards
- **Table Width:** The calculator assumes a table width of 90cm. For wider tables, increase the chain length by approximately 5-10cm per additional 30cm of width to maintain visual balance.
- **Ceiling Height:** Consider your ceiling height when determining the overall look. A shorter chain (under 60cm) works well with ceilings under 2.4m, while taller ceilings allow for longer chains (up to 1.2m or more).
- **Shade Diameter:** The calculator incorporates a standard shade diameter of 18cm. If your pendant light has a larger shade, increase the chain length accordingly – perhaps an extra 5-10cm.
- **Dining Tables:** For dining tables, aim for a chain length between 75cm and 120cm to provide adequate headroom above the table surface.
- **Kitchen Counters:** Countertop pendant lights generally require shorter chains, typically 60cm – 90cm, ensuring sufficient space for food preparation without obstructing movement.
Worked Example: Dining Table Pendant Light
Let's say you’re purchasing a pendant light for a dining table that is 90cm wide and you want the bottom of the shade to be 75cm above the tabletop. Using the calculator, inputting 75cm gives us a chain length of approximately 138cm (75cm + 63cm). This means you’ll need a pendant light with a cord or chain that is at least 138cm long – ideally, choose one with an extra 10-20cm for flexibility and easy installation.
Purchasing a 140cm chain would provide ample room, allowing you to adjust the height slightly if needed. This example demonstrates how a standard calculation can quickly determine the necessary chain length for a common dining table setup, saving you from overspending on unnecessary length or struggling with a too-short option. The estimated cost of a suitable 140cm pendant light chain would be around £15 - £30 on Amazon UK.
More questions answered
What if my table isn't exactly 90cm wide?
Adjust the calculator’s input for table width. For example, a 120cm table would require an additional 30cm of chain length (63cm). Consider the overall balance and visual appeal when making adjustments.
How does this calculator account for different ceiling heights?
The calculator uses your desired tabletop height as input, which is measured from floor to tabletop. This effectively accounts for variations in ceiling height – a taller table will require a longer chain regardless of the ceiling's actual height.
What if I want the light shade closer to the countertop?
Reduce the calculator’s input for desired tabletop height. A lower table requires a shorter chain, but ensure there’s enough clearance between the bulb and the surface for safety and practicality.
Can I use this calculator for kitchen pendants over countertops?
Yes, absolutely! The same principles apply – focus on the desired countertop height (typically 80cm - 90cm) and ensure adequate space above for movement.
What if my pendant light has a very large shade diameter?
Increase the calculator’s input for shade diameter to account for the extra space needed. Add an additional 5-10cm of chain length for every 5cm increase in shade diameter.
Does this calculator cover adjustable pendant lights?
The calculator is primarily designed for fixed-height pendant lights. Adjustable lights may require a slightly longer chain to allow for full movement and positioning – consider adding an extra 10-20cm.
What units are used in the calculator’s results?
All measurements are provided in centimetres (cm). You can easily convert this to metres by dividing by 100. The calculator provides a chain length suitable for standard installation practices.
I've entered the values, but the result seems too short – what am I doing wrong?
Double-check that you’ve accurately inputted your desired tabletop height in centimetres. Ensure there are no typos or errors in your calculations. Consider adding an extra 5-10cm for adjustments.
Can I use this calculator to estimate the length of a chandelier chain?
While designed primarily for pendant lights, you can adapt it for chandeliers with similar considerations – focus on the desired shade height above the tabletop or room surface. However, chandeliers often have more complex hanging mechanisms, so professional installation is recommended.
Where can I find a suitable pendant light chain after using this calculator?
