![]() ambient light), but I wanted to pause and see if I am on the right track. I also understand that much more goes into the selection of a screen as additional factors come into play (i.e. ![]() Simply enter any known screen dimension and the others will be calculated. The primary assumptions are that Nyquist limits the maximum. This tool calculates 2 of 3 dimensions for you in cm and inches. If you don’t already know the aspect ratio of the screen, try our aspect ratio calculator. If you already know it, great, feel free to move on to the next step. 32' 40' 43' 50' 55' 60' 65' 70' 75' 80' 85'. Step One: Find the Aspect Ratio The first step to calculating screen size is to find the screen’s aspect ratio. Use our size to distance calculator to see which size TV you should get based on how far away you'll be sitting from the screen. (531 / 35.88) * 2.07 or 30.63 ft-lambertsĪssuming (again for illustration) the ideal is 16 ft-lamberts (from ), and that all factors above are fixed other than gain, one should shoot for a screen with gain of ~1.1 calculated as follows Limiting display resolution calculation based on your vision, screen size and seating distance. Size not only affects the price of a television, but it also has a huge impact on the perceived picture quality. ![]() Let’s assume:ġ) 35.88 sq ft screen size (default from the ECSIS at B12).Ģ) 2.07 screen gain (default from the SGC at J30).ģ) 531 calibrated lumens (from – Theater Black with low lamp power).Ĥ) Ft-lamberts = lumens / screen square footage x gain. Now to my point - as I attempt to tie screen size, gain and ft lamberts together. However, your format is much better, and the use of Excel’s protection and error condition features are very clever). Your All Screen Gain Calculator (“SGC”) and Easy Calculator for Screen and Image Size (“ECSIS”) are quite useful (I created a similar screen size calculator before discovering yours and it proves the math. Screen & Image Size Calc (Works).zip 4.58984375k. See post #25 below for this more comprehensive version of the calculator. Your comments/criticisms are invited.ĮTA- Thanks to member 1canuck2 for adding to the Easy Calculator to include calculating how the screen fits onto your screen wall. Either version will also run in the spreadsheet portion of Open Office, a free download. The calculator is provided in two versions, one for use with MS Excel (preferred) and a second for use with the less capable, but more widely distributed, MS Works Spreadsheet. It also lets you see at a glance the image height, width, diagonal, and area for five user-modifiable image aspect ratios when projected onto the specified screen. The calculator then computes the viewing area dimensions, as well as the total screen height and width including the frame or border. The calculator lets you specify the screen size (diagonal, width, or height), the screen aspect ratio, and the frame (or border) width. Width: Height: Diagonal Inches: Screen ResolutionĮnter your TV or PC screen resolution in pixels, HDTV use 1920x1080px but some computers and TVs have different resolutions, some 4K screens have 3840x2160px, Apple MacBook Pro Retina have 2880x1080 and there is a lot more resolutions on mobile devices.This simple, user-friendly calculator may be helpful to anyone planning to buy a screen. xĮnter your screen dimensions in inches in one of the following fields, this form will automatically change the values on the other fields based on the value you provide, if you only know the width, height or diagonal size it will calculate the other values for you. If you don’t know your screen aspect ratio enter your screen resolution in order to get your aspect ratio above. Aspect RatioĮnter your screen aspect ratio, old TVs use 4:3 and modern TVs use 16:9, some computer screens use other aspect ratios like 16:10 for instance, you can choose a preset or specify your own value. Resolution (px) Width / Pixel pitch 500/2 Resolution (width) 250 px Same with height, Resolution (px) Height / Pixel pitch 500/2 Resolution (height) 250 px The final cabinet resolution 250 x 250 px (w x h) Now if the LED display consists of 5 cabinets in width and 3 cabinets in height. Do you ever wondered if your display is retina? At which distance your screen will look like a retina display? What is your display aspect ratio? Or maybe just want to know your screen PPI/DPI in order to configure Photoshop to see your images at an accurate print size, for that purpose I created this little calculator.
