Making a powerpoint that's supposed to show a before and after of a website. Since it's currently a long website I'd rather make a single long slide to put it on (20" instead of 7.5"). But all the other slides in the presentation should be normal-sized.
I found Slide Size (Design ribbon, Customize section) but that resizes ALL slides.

if you want to shrink one slide for instance, add shapes to hide the unwanted background margins. you can set the shape color filling as the background (gray or black). It's "ugly" but it works
Although you cannot use different sized slides in one PowerPoint file, for the actual presentation you can link several different files together to create a presentation that has different slide sizes.
The process to do so is as follows:

You can't. You can only have one slide size and one orientation per presentation.
Are you projecting the presentation or delivering it on a laptop?
If so, the size is sort of irrelevant.
Regardless of the slide size, the projected/displayed image will never be longer or wider than the projector/display accepts.
True you can't have different sized slides. NOT true the size of you slide doesn't matter. It will size it to your resolution, but you can click on the magnifying icon(at least on PP 2013) and you can then scroll in all directions of your slide in original resolution.
true, this option is not available in any version of MS ppt.Now the solution is that You put your different sized slide in other file and put a hyperlink in first file.
