Open the File->Page Setup dialog:

draw.io file menu

And enter the paper size you require:

Just because this question comes up when you search "infinite canvas draw.io", here's how to make an actual infinite canvas:

On the right-side tray, select the "Diagram" tab and uncheck "Page View":

    The page background view is nothing to do with what part of the canvas is usable. The canvas is "infinite" all the time, just if you drop a shape where there's not already a page drawn, it will draw it there. Aug 9, 2023 at 12:24
