When I open a PDF and set it to 100% zoom, what exactly does that mean? 100% of what?
If I have a landscape letter size page, 100% zoom goes beyond the visible Reader window. I am supposing this has something to do with document and screen resolution, but PDF Properties doesn't list a document's resolution, only it's size.
Related to this, if I want a document to open at 100% and give a specific size, say 1920 x 2400 pix, how would I go about achieving that?
Thanks.

100% zoom means that 1 inch of the PDF page will appear on 1 inch of your screen.

Thanks for the reply. But, an 11" wide document at 100% is displayed as 14.75" on screen. So that doesn't seem to be it.

Then check the "Scale for screen resolution" setting under the application's Preferences, in the General tab.

Thanks. Changing from the current setting of Auto-Detect to No Scaling does change the 100% size down to 11_7/8", but still not 11".
By trial and error, it seems the 100% zoom level doesn't depend on the resolution at which the PDF was published. Any resolution gives the same 100% screen size for the same paper size. But 100% screen size does depend on PDF paper size. At a larger paper size of the same content, 100% gives a larger view size for the same object, ie. a higher real zoom level. In other words, an object printed on Letter size appears smaller at 100% than if the same object is printed on Tabloid. Which does show - as you say - a relation between paper dimension and screen dimension at 100%. It just doesn't seem to be one-on-one.

It is for me... Maybe there's some other scaling going on in your machine.

PS. I don't have a "No Scaling" option in this setting. I have "Auto Detect", "100%", "200%" and "System"...
