If you plan on using AirPlay to show your slides on a standard flat-screen TV, then the 16:9 aspect ratio is probably your best bet. Digital cameras have changed that, and our Keynote slide templates come in either 4:3 or 16:9 aspect ratios. Back in the days of photo film, just about every photo had either a 1:1 (square) or 4:3 aspect ratio. You’ll also have a choice of aspect ratio - the ratio of image width to height.

On the Mac, launch Keynote and select a template from the choices available.
