What TV Size and Viewing Distance Ranges is for
TV Size and Viewing Distance Ranges is the page to open when you need tv size and viewing distance ranges from measurements you already have. It belongs with the other tv & video calculators because that is the work this arithmetic supports. The diagonal those charts start from is the screen size. Type the entries first. The result stays hidden until you press Calculate, so a half-finished form never flashes a number you might mistake for the answer.
How to fill in this calculator
This page is the written companion for the tool. Where the form asks for a measurement, enter it in the unit printed on that field, then press Calculate. Nothing is computed while you are still typing.
The formula in plain language
A 16:9 screen's width is the diagonal times 16 divided by the square root of 337, and the height uses 9 instead of 16. Viewing distance for a modern television is often near 1.5 to 2.5 times the diagonal, closer for a sharper panel and farther for a 1080p set. Pixels per inch is the diagonal pixel count divided by the diagonal in inches.
A worked example
A 65 inch 16:9 television is about 56.7 inches wide and 31.9 inches tall. Sitting about 8 to 9 feet away matches a common 1.6-times-diagonal suggestion.
A screen chart and a viewing range describe the same television. This tv size and viewing distance ranges page belongs with 16:9 screen size chart and display resolutions.
Mistakes that move the answer
- The diagonal is the picture, not the outside of the frame.
- A 16:9 screen will not fill a 21:9 window without bars or cropping.
How to check the result
After Calculate shows the tv size and viewing distance ranges result, redo the last operation with a pencil using the rounded figures on the screen. Matching that check means the inputs were read correctly. If you edit a label or a sentence in this HTML file, reload the page. The form and this article both live in the file, so the edit is what visitors will read.
