To change the font on all slides in a presentation in Google Slides, you need to use the Master Slide.

What is a Master Slide?

A Master Slide works like a template for your presentation. It defines the theme, layout, colours, fonts, backgrounds etc in your presentation. The default master slide in Slides has a white background and uses the font Arial. So when you create a new, blank presentation (or insert a new, blank slide) this is the default formatting that Slides uses. The blank slide and the formatting in the text placeholders used on it, are all defined in the Slide Master. If you, for example, insert an image (such as a logo) onto your Master Slide, each new slide that you create will have the image on it, in exactly the same position.

Using the Slide Master is an easy way to change the look of an existing presentation. Or make changes to all of the slides in your presentation. In this case, we are going to use the Master Slide to change the font to a different one, throughout the presentation.

  10. I have a subtitle as part of my presentation, so I clicked on the layout that contained a subheading

    Select subtitle slide layout

  11. The slide containing the subheading is highlighted (the Title slide), so I know which slides will be effected by any changes I make (see above image), and across the top of the master slide you should see that the Title Slide is used by 1 slide
