Calculate the minimum nits you actually need for your environment. Avoid the two most expensive mistakes in digital signage: a screen that is too dim to read, and hardware you overpaid for.
Screen brightness is measured in nits (candelas per square meter). The right level depends on your ambient light conditions, viewing angle, and content type.
Common mistakes to avoid:
This calculator uses industry-standard formulas for contrast ratio and readability. Always verify specifications with your display vendor and consider a site survey for critical installations.
This digital signage brightness calculator answers one simple question: will people actually be able to see what you put on that screen, or are you about to install very expensive wall glow?
If the calculator result feels higher than you expected, it usually means one of two things: the space is much brighter than people admit, or someone was trying to squeeze an indoor-grade screen into a semi-outdoor problem.
Those beautiful window displays sitting behind glass are classic victims of underpowered screens. Run the calculator with Semi-Outdoor or Outdoor - Partial Sun, ambient light at 5,000 lux and up, and text or mixed content type. A result in the 1,500 to 3,500 nit range is normal. If your hardware tops out at 400 nits, you are shopping in the wrong aisle.
These spaces are technically indoor but behave more like semi-outdoor. Set Indoor - Bright Light, ambient at 1,000 to 5,000 lux, and medium to far viewing distance. You will usually land between a high-bright indoor and a semi-outdoor spec.
Wayfinding has a special failure mode: when it is hard to read, people bother staff instead. Use the calculator to size brightness for corridors and mixed-lighting lobbies so your maps and directions stay readable rather than washed out.
For anything exposed to sun, plug in Outdoor - Partial Sun or Direct Sunlight with higher ambient lux and far viewing distance. If it tells you that you need 3,500 to 5,000+ nits, it is not being dramatic. That is the difference between a high-impact media asset and a very expensive gray rectangle at noon.
Use these typical ranges as a gut check against the number this calculator gives you.
If your calculator result is below 400 nits, commercial-grade indoor displays are fine. Between 400 and 1,000 nits, consumer TVs are going to look tired. At 1,000 nits and above, high-bright or semi-outdoor displays are the realistic baseline. At 2,500 nits and above, you need outdoor-rated hardware with proper power and cooling planning.
