Added pixel density calculation (useful when using as a PC monitor). Added hints to help enter panel resolutions (hint lists commons resolutions). Added 16:10 aspect ratios for LCD monitors.

Version 2.6: Added LCD/Plasma support.

Version 2.7: Edited notes fields to improve clarity for data entry fields.

screen size based on published standards.” screen size based on screen resolution” and “ seating distance vs.

Version 2.8: Added charts for “ seating distance vs.

Version 2.9: Added 2.40:1, 2.70:1 screen aspect ratios, added ‘hover’ comments to better explain the different seating distances added conditional formatting on the screen brightness result cell (red if brightness is too low, yellow if it is close to being too low).

Version 3.0: Added minimum viewing distance calculation, added conditional feedback on seating distance for each specification (seating distance too far, etc.), added first row and second row seating distances (for conditional feedback on seating distances), added field-of-view results (in degrees), added ability to calculate projector throw distances for any screen size (just enter the throw information for one screen and it will interpolate for other screen sizes), fixed mis-spelling that was causing formulas to break.

Version 3.1: Fixed unit conversion formula that was causing “Second Row Field-of-View Width” to not calculate when any unit besides “inches” was selected.

Corrected spelling mistakes on one of the extra tabs within the spreadsheet.

Version 3.2: Changed anamorphic aspect ratio from 2.35:1 to 2.370370:1, which is the correct value for a 16:9 projector with a 4:3 anamorphic lens.

Version 3.3: Added 2.35:1 aspect ratio back.

Version 3.4: Widened columns that were causing being truncated for international users.

Version 3.5: Fixed bug in the aspect ratio input that caused international users to have problems (problem was related to using “,” as decimal delimiter instead of “.”) Added cells to the far right of the spreadsheet to allow changing and adding custom screen aspect ratios.

The default is 20/20 vision changing the input to 20/10 vision with show that the viewer will be able to spot resolution deficiencies at much greater distances due to more acute eyesight.

Version 3.6: Added feature to allow calculation of Visual Acuity Viewing Distance based on eyesight of the viewer.

Version 3.7: Clarified back row platform height input fields, modified formulas to prevent negative platform heights (user info message instead), changed spreadsheet defaults to better fit a typical home theater.

Version 4.0: Added Anamorphic (horizontal expansion) front projector lens option, which adjusts projector brightness and throw ratios when selected.

Please download it and put it to good use! I noticed on various forums that others could probably benefit from this spreadsheet, so I cleaned it up and I’m now making it available to the public. Over the past several years, I’ve slowly constructed a spreadsheet to meet all of my home theater design needs.
