Inputs

Fan diameter m Enter a numeric project value in m at or above 0.1. Fan centre X m Enter a numeric project value in m at or above 0. Fan centre Y m Enter a numeric project value in m at or above 0. Minimum radial clearance m Enter a numeric project value in m at or above 0.

Downlight positions

Add one row for each relevant space, item, zone, document, or measurement set.

Row 1

Fixture X m Enter a numeric project value in m at or above 0. Fixture Y m Enter a numeric project value in m at or above 0.

Row 2

Fixture X m Enter a numeric project value in m at or above 0. Fixture Y m Enter a numeric project value in m at or above 0.

Minimum radial clearance -- m

Fixtures below stated clearance --

All fixtures meet stated clearance --

Important notes

Check the fan manufacturer installation zone, blade sweep, downrod, light kit, vibration, and structural installation requirements.
This planning result does not determine electrical, structural, or Australian installation compliance; obtain installer review before work.

Formulas

\(\displaystyle C_i = \sqrt{(x_i-x_f)^2 + (y_i-y_f)^2} - \frac{D_f}{2}\)
The clearance check is radial and two-dimensional; fan manufacturer requirements remain authoritative.

Check radial spacing between a ceiling fan and planned downlight positions using a stated clearance assumption.

Ceiling Fan and Downlight Clearance Planner is a planning aid. Keep the target source, product data, measurement method, and project assumptions with the result. Confirm compliance, installation, certification, and safety decisions with the responsible professional.
