Here's what I tend to do: 1) Start Sketchup - any or no model.2) Adjust (manually) your viewport size to roughly the size you need.3) Check the exact pixel size after every adjustment by:a) File/Export/2D Graphicb) Click Options...c) Tick Use view sized) Note Width and Height and click Cancel4) Repeat 2) and 3) until you hit e.g. 1280x6405) Quit/Restart Sketchup and verify that it re-opens with the last used window size. This produces pretty much exactly the size you want (sometimes off by one pixel in either direction) - at least for viewports <= screen size. Accurate setting of viewport - SU Podium Forum
