Word-document size

By itself, Word 2013 doesn't save the current view and zoom settings in the document file. You can download an add-in from http://jay-freedman.info/ that will force those settings to be saved and then used when the document is reopened.

Download SaveView2013.zip, and follow the instructions on the web page to install it.

“Extract the contents of the zip files to your desktop or to a convenient folder.” Clicking on this, I found that no User Account Control box made itself visible. Instead, I got the message: “You attempted to download something from an unfamiliar and potentially dangerous website. You should only download programs from sites you trust.” 

The sentence you quoted doesn't appear anywhere on my web page. The paragraph under the SaveView2013.zip link says:

  Instructions: Right-click the downloaded zip file, click Properties, and click the Unblock button; then click OK. Extract the SaveView2013.dotm file from the zip, and store it in the folder

  %appdata%\Microsoft\Word\STARTUP

If Word is running, close it and reopen it.

If you follow those instructions and you still get the same message, it's probably coming from an overzealous antivirus program; I've never seen that wording from Windows itself.

The zoom scale is an application setting, not a document setting. Consequently, all documents open at whatever the default zoom size is.

Really? I've just begun using 365's version of Word, and documents seem to open at whatever zoom scale I last defined in any document. E.g., if I open a document and then set its zoom scale to 160%, the next document I open will also appear at 160%, although I haven't changed the application setting (unless changing one document's zoom scale makes that the new application default, which I hope is not true).

In this case, "default" is not the correct term. Instead, I would say it's the "current" zoom setting, which you can change at any time. That current setting will be used for any document you open, until you change the setting.

It is correct that the zoom is an application setting that isn't saved in the document file. If you want to save each document's zoom setting in that document's file and restore it on reopening, use the add-in that I mentioned in my October 2 post.

Jay - Thanks for your reply. I will consider that add-in.

But I just want to say (to Microsoft) that I think it's a terrible idea for the zoom setting on one document to become the "current" one that applies to other documents. I'd greatly prefer zoom to be a per-document setting, not a per-application one. (A user should be able to change a default zoom setting if that user wants all documents to open at a certain zoom level.)
