This might be a bug in screenruler. If I change the DPI of the screen and the document is set to 100% (representing physical size), then, the document should change its size. That is, if the document is A4 and I put an actual A4 sheet on top of the screen, changing the DPI should not change the document size.
Nevertheless, the 100% zoom of evince 3.8 is slightly wider in my screen in 3.8 (not smaller) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/311614 Title: If DPI in X != DPI in Gnome, document dimensions are not true at 100% zoom Status in Evince document viewer: Unknown Status in “evince” package in Ubuntu: Confirmed Bug description: Binary package hint: evince From File->property you can get the dimensions of a PDF you're viewing. At 100% zoom level, the document is about 20% smaller (in each dimension) than it should be. For comparison, screenruler shows the right dimensions, so it should be possible taking screenruler's detection algorithm which seems to work better. [Update] The cause is a discrepancy between the DPI value in Gnome and in X: All other programs read the Gnome value, while Evince reads from X.
