How to Use This Calculator
- Enter stage width (m) and stage depth (m) for your performance space.
- Set the target light level (lux) — 500–800 for drama, 1000–1500 for dance/musical.
- Select fixture type (1 = Conventional 575W, 2 = LED ~150W, 3 = Moving Head ~350W).
- Review Number of Fixtures needed, Total Power (kW), and Circuit Load.
- Use the fixture count to plan your lighting rig, dimmer racks, and cable runs.
How the result changes with Throw distance (m)
| Throw distance (m) | Front wash fixtures | Total fixtures |
|---|---|---|
| 4.8 | 15 | 61 |
| 12 | 9 | 55 |
| 20 | 8 | 54 |
| 27 | 14 | 60 |
What each input means
- Stage width (m)
- Width of the performance stage in metres.
- Stage depth (m)
- Depth of the stage from front to back.
- Target light level (lux)
- Desired illumination at stage level (500-800 drama, 1000-1500 musical/dance).
- Fixture type (1-3)
- 1 = Conventional (575W), 2 = LED (~150W), 3 = Moving Head (~350W).
- Throw distance (m)
- Distance from lighting position to the stage (front of house to stage centre).
What each result means

- Total stage area.
- Front wash fixtures
- Number of fixtures for the primary front wash.
- Back light fixtures
- Fixtures for back lighting (separation and depth).
- Side light fixtures
- Fixtures for side/cross lighting from both wings.
- Specials
- Focused specials for solos, set pieces, and effects.
- Total fixtures
- Total fixtures for a complete lighting rig.
- Total power (kW)
- Total electrical power draw at full intensity.
- Total amps (208V)
- Current draw at 208V theatrical power.
- DMX channels

- DMX universes
- Number of DMX universes (512 channels each).
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersStage width (m) = 12, Stage depth (m) = 8, Target light level (lux) = 800, Fixture type (1-3) = 1 = 5 input(s) provided
- Calculate Front wash fixturesFront wash fixtures10 = 10
- Calculate Total fixturesTotal fixtures56 = 56
- Calculate Stage areaStage area = stageWidthM * stageDepthM96 = 96
- Calculate Back light fixturesBack light fixtures24 = 24
