Pendant Lights Count Calculator

Calculate how many pendant lights fit in a row with a chosen minimum edge gap.

How to use Pendant Lights Count Calculator

1. Enter Available Width, Item Width, Minimum Gap. Use the matching measurement or purchase unit. 2. All items have equal positive widths. Only internal gaps are included; outer side margins must be deducted from available width first. Widths describe fitting bodies and gaps are edge to edge. These measurements do not determine mounting, electrical installation or clearance requirements. 3. Select Calculate or press Enter to see maximum items that fit. 4. Select Select Copy result to copy the answer, or Reset to clear the form.

Why use this tool?

Use this calculator to plan a horizontal row of light fittings. Widths describe fitting bodies and gaps are edge to edge. These measurements do not determine mounting, electrical installation or clearance requirements.

How the calculation works

Maximum count = floor((available width + minimum gap) ÷ (item width + minimum gap)). All items have equal positive widths. Only internal gaps are included; outer side margins must be deducted from available width first. Widths describe fitting bodies and gaps are edge to edge. These measurements do not determine mounting, electrical installation or clearance requirements. Counts and comparisons use exact entered decimals. Other dimensions display up to six decimal places, with scientific notation for smaller nonzero results. Input and result magnitudes are limited to 9,007,199,254,740,991. Currency uses the selected currency’s minor unit.

Example

Pendant Lights example: In 200 cm, four 40 cm items plus three 10 cm gaps need 190 cm; a fifth item would need 240 cm.

Practical tip

Check the chosen fitting’s installation and clearance instructions separately. Centre-to-centre distance equals the body width plus the edge gap.

Frequently asked questions

What does this result include?

All items have equal positive widths. Only internal gaps are included; outer side margins must be deducted from available width first.

Does this choose the right installation or allowance?

Widths describe fitting bodies and gaps are edge to edge. These measurements do not determine mounting, electrical installation or clearance requirements.

How should I interpret rounding and units?

Whole purchase counts round up and maximum fit counts round down using the entered decimals exactly. Other dimensions use up to six decimal places; smaller nonzero results use scientific notation. Currency rounds to its minor unit, with smaller positive costs labelled explicitly. Unit selectors describe the input unit; changing one does not convert entered values.
