About TV & Video calculators
TV and video calculators help you reason about screen geometry: viewing distance, aspect ratios, and pixel density for a given setup. They are useful when shopping or mounting a display.
Room lighting, furniture, and personal comfort still matter—numbers are only part of the experience.
Common use cases
- Choosing a screen size for a room or desk
- Aspect ratio and resolution trade-offs
- Planning mounts and furniture with fewer surprises
