Is it possible to set an exact document size in Google Docs? I am specifically using Google Drawing.
I cannot find any options or ways to do this.
I don't see any direct way to do this but here's a suggestion for a hack that might work. Create an image that matches the output resolution you need; even simple image editors like ms paint will allow you to do this. Import this image to your drawing and align it with the top left corner of the drawing. Then click on the background and drag on the handle that shows up on the bottom right hand corner. After adjusting the size of the page to match the imported image, simply delete the image from the drawing.
If you're creating a drawing for print, include the dpi setting that will be used on the printer. For example, if you'll be making a print on an 8.5" x 11" sheet of paper at 300dpi, create an image that is (8.5 x 300)px x (11 x 300)px.
This can quickly become troublesome if you need output at multiple resolutions.
Size of Document
With the following stand-a-lone script you can retrieve the size of a non Google Document type (the rest is zero by size):
It looks like this
Open the file (PDF) by right clicking the doc and select "Open With: Google Drive Viewer":
Select the key of the document and add it to the app. Press "get size" and the size will appear.
