Measure. Understand. Plan.
Video & display calculators
Planning a TV, projection or camera setup? Find the screen size and seating distance that fit your room, explore display resolution, or convert lens detail into sensor pixels. Choose your question below.
FGRD
How much resolution does your screen need?
Enjoy the image without pixel structures or flickering detail drawing your attention. FGRD helps you plan resolution for your screen and seat, including sampling and diagonal-detail factors beyond a visual-acuity-only estimate. Start with the screen size and distance you know.
Open calculatorFOV
Find your viewing distance and field of view
Does a larger screen fit your room, and how much of your view will it fill? Enter the screen diagonal and seating distance. You will see the viewing angle and can work backwards from a chosen angle to a suitable distance.
Open calculatorLP/mm
Convert LP/mm to sensor pixels
Lens and film data often use line pairs per millimetre; cameras use pixels. This calculator connects the two. Enter the detail frequency and recording area to explore the pixel count and sampling margin for your camera or scan.
Open calculatorUse the right tool for your question
Planning a display or projection setup? Start with viewing distance and FOV. Its screen geometry is also the starting point for the FGRD resolution model. Choosing a camera sampling strategy? The LP/mm tool relates optical spatial frequency to sensor dimensions.
Each calculator explains its assumptions. Results are planning aids: screen perception, optical performance and final image quality also depend on contrast, processing and the complete imaging chain.
