This is a little cryptic, so I will not be offended if you do not understand: Go to File > Document Properties, and find the part that says "Custom Size". Adjust the height and width till you get what you want (you will probably need to move the objects around on the document to get it right). Alternatively if you just want to eliminate blank space around the edges, you can select all objects you wish to be in the picture and click "Fit page to selection". Was this what you wanted? ''''
