Actually, there is a way to display a document in InDesign at what I call “true actual size”, which means if you lay an 8.5x11 sheet of paper over the display of an 8.5x11 page, they will be the same size. Here is what I posted in previous years (last time was 2014), but apparently that has been culled with time. I have updated it for InDesign CC 2020 (Version 15). How to display at true actual size (Mac) November 21, 2019 The solution to achieving "true actual size" is a script written by Dave Saunders (and probably others) some time ago, If you're like me and don't really use scripts, here is what to do with it on a Mac (with apologies to Dave and other experts who know a helluva lot more about this than I do): 1. Copy the text for this script: //by Dave Saunders. Replace the percentage number with the correct value for your screen app.layoutWindows[0].zoomPercentage = 113; 2. Paste it into a text file (I used TextEdit) and leave the file open. You will save it later. 3. Go to Acrobat Pro>Preferences>Page Display and under Resolution note the number associated with "Use system setting". (On my system it is 81 pixels/inch. Note that enabling that setting also makes Acrobat display at true actual size. However, there is a long-standing bug with Acrobat that can make Acrobat slow to an agonizing crawl with multi-page PDF files when using this setting, so I use “Custom Resolution” as my default unless I need true actual size.) 4. Divide the number from Acrobat by 72, then multiply by 100. (This is essentially a percentage calculation of system resolution over the conversion value of 72 points/inch, which produces 112.5 in my example. I rounded it to 113.) 5. In the open text file, change the number 113 to what you got from the above step. 6. Save the file with the name “True actual size.jsx” to this location: Users/[username]/Library/Preferences/Adobe InDesign/[version]/[language]/Scripts/Scripts Panel Note that the file extension must be .jsx 7. Test the script in an open InDesign document by going to Window>Utilities>Scripts, then click on User and double click on your script. The display should now show your work at true actual size. 8. The Scripts panel is awkward at best, so the last step is to assign a keyboard shortcut to your script. I use Control-1. Go to Edit>Keyboard Shortcuts… and choose Scripts in the Product Area menu. Scroll down to the bottom, where you should see your script listed. Highlight it and enter Control-1 (or whatever you prefer) into the New Shortcut window and click Assign. Then click Save. (You won't be allowed to modify the Default set, but I just went with "Default copy”.) Now whenever you want to view your work at true actual size, just hit Control-1 (or whatever you chose for a keyboard shortcut). You might want to copy these instructions into a TextEdit file and save it where you will find it when the time comes to upgrade InDesign CC again, because it’s likely that you’ll need to achieve true actual size all over again. Lastly and far from least, thank you for the script, Dave! If you or other pros come across this and see corrections or improvements, please set me straight.
