How to Make a Poster in Google Slides
To announce any event, from birthdays, concerts, or even a graduation ceremony, a poster with all the necessary information is the perfect solution, as it is original and will ensure that everyone who sees it retains the most important information of the event in question. In addition, it is a great decorative element for any place.
However, how can we create these creative designs? At Slidesgo, we have some A3 Google Slides and PowerPoint templates ready to be printed to get amazing posters. You can filter your search on our website so that the results you get are A3 or even A4.
However, if you want to create the design yourself from scratch or adapt another design to the desired format to create the poster, in this post we will explain how to make a poster using Google Slides. Here we go!
How to make a poster in Google Slides step by step

- Open a new presentation in Google Slides. By default, the format is 16:9. To adapt it to the size you want your poster to be, click on File > Page setup. A small tab will appear where we can configure the slide. From the drop-down, select Custom and set the size. In the example, we have used a vertical A3 format (29.7 x 42 cm)
- If you click on Theme, you can use one of the defaults themes Google Slides for your design, but if you need a more professional style, at Slidesgo we have a wide variety of templates, even with formats such as A3 and A4 already defined. Take a look!
- You can also adapt a 16:9 presentation to the size of your poster. Just follow the same procedure as above, except that instead of opening a new presentation, open a previously created one. In the example, we have set the slide in A3 horizontal format (42 x 29.7 cm).
- If you want to print your poster, just download the presentation to your computer. You can delete the slides you don't need or download the entire presentation as a PDF. To do this, select File > Download > PDF Document. If you need more information about this process, you can read our tutorial on how to export a Google Slides presentation as a PDF file.
And that's it! Now you can print your poster and place it wherever you want, but make sure everyone is able to see it! We're sure it's an amazing design!
