Brightness Calculator
Our brightness calculator is used to determine how bright of an image you will get based on projector lumens, screen size and screen gain. View the result in foot lamberts (ftL) or nits (cd/m²).
SDR TV/video is commonly mastered around 100 nits (30 ft-L). HDR content is mastered with much higher peak luminance, so projectors use tone mapping to preserve overall image balance, contrast, and highlight detail.
How It Works:
Start with your screen's aspect ratio, or provide custom dimensions. You can provide either the diagonal size, width or height - we'll convert the dimensions for your convenience!
| ftL | Viewing |
| Not bright enough Below recommended projection brightness for most home theater use. SDR will look dim, and HDR will appear heavily tone-mapped with limited impact. | |
| Good for dark room Good for SDR/cinema-style viewing in a dark room. HDR can be displayed, but highlight impact will be limited. | |
| Good for low ambient light Strong SDR brightness and suitable for tone-mapped HDR projection in a light-controlled room. SDR TV/video is commonly mastered around 30 ft-L. Extra brightness mainly helps the image stay balanced against low ambient light. | |
| Good for medium ambient light Provides more brightness headroom for ambient-light viewing and tone-mapped HDR projection, helping the image retain contrast, midtone balance, and highlight separation. | |
| Good for high ambient light Excellent brightness for ambient-light resistance and HDR tone mapping, helping the image maintain punch and separation in brighter environments. |
