Pendant Light Size Calculator
Estimate a useful comparison range for pendant width, total span and spacing above a table, kitchen island or bar. The formula uses the finished surface dimensions and is intentionally shown as a range so you can test real products rather than follow a false exact answer.
Enter dimensions and calculate.
How to use the result
The calculator compares a total visual span of roughly one-half to two-thirds of the surface length and limits individual fixture width in relation to surface depth. Open or transparent fixtures may feel lighter; dense stone or opaque shades may feel larger. Always make a full-size mock-up.Important: This tool provides design starting points, not electrical, structural or code approval.
