Best Free Google Slides Themes for 2025

When PowerPoint was first released in 1987, it was a game-changer for presentation design.

Before PowerPoint, decks were mainly done by hand — presented via a clunky piece of kit called an overhead projector — and could be both time-consuming and expensive to create. 

Since then, several presentation software programs have come along, giving professionals and hobbyists more power and creative freedom than ever before. 

And within that bunch, Google Slides is arguably one of the most popular today.

Google Slides has become a top PowerPoint alternative (along with Apple’s Keynote) for a few reasons. For one: it is completely free. But it’s also very user-friendly, and it allows for super easy collaboration across people or teams. Google Slides makes it possible for pretty much anyone to create a great presentation, whether it’s meant to close a business deal, increase your chance of promotion, or help students grasp a complex subject area. 

What’s more, Google Slides has thousands of ready-made presentation themes to choose from. And herein lies the problem: there’s almost too many options to sift through — a quick browse of the Google Slide themes might just leave you feeling overwhelmed.

True: excellence in theme design isn’t easy to find. So we found it for you! 

In this article, we’ve rounded up the best Google Slides themes for 2020, broken down by industry. Each of these Google Slide themes is on-trend, and selected with our users’ preferences in mind. So trust us when we say that these Google Slides themes will enable you to create a professional presentation within minutes.

Best Google Slides Themes for Business Presentations 

Let’s get down to business. 

When you’re standing up in front of a client, business partner or corporate team, you want to be taken seriously. And the fastest way to undermine trust and confidence in your presentation is with a confusing or sloppy deck design. 

But, when done right, business presentations can be a very effective tool to present projects, reports, sales results, or business pitches to groups and individuals. In fact, it’s estimated that more than 30 million presentations are given at work, each day! 

So how do you use Google Slides to create compelling, trustworthy and authoritative business presentations?

There are a few things to consider you need to consider.

Business presentation themes require a professional look. Just as you want to look well-put-together when giving a presentation, your slide theme should as well. This means avoiding any seriously outlandish color schemes and typefaces which appear too informal or childlike (Comic Sans, we’re looking at you!). 

Plus, your chosen Google Slides theme also needs to be easily adaptable to your corporate identity — adding in your company’s logo, and using your particular brand colors and fonts can go a long way. 

The themes we’ve chosen below help you to do just that!

Best Google Slides Themes for Marketing

We all know how significant brand colors are for organizations.

And marketing presentations are just an extension of this. These decks must be visually stimulating, persuasive, and should feature graphic elements which help deliver the message you’re sending across.

Perhaps you’re sharing the results of a recent marketing campaign, in which case you should be bold and proud of what you’ve achieved. Here, a modern design, with attention-grabbing photos and illustrations, will make your content pop. 

In other cases, you might be updating the wider business team on how they can help support the marketing objectives. Here, something a little softer, which encourages collaboration and creativity should do the trick.

Just be sure whatever theme you choose has the correct feeling behind it, and that the design you select doesn’t take away from your chosen topic.

What are the advantages of ready-made Google Slides themes?

Design plays an important role in the success of your presentation, regardless of your industry or sector. The right presentation theme will engage your audience, and help you deliver the message or data in an easily digestible way. 

Thing is, a lot of us enter presentation giving with a little trepidation. And public speaking is still a major phobia for a lot of people.

But you know what helps you feel more prepared and ready? Having a beautifully designed presentation deck to fall back on.

In a recent poll, 91% of participants agreed that they would feel more confident if they knew their presentation was beautifully designed, and 88% of people said they put “quite a bit” or “a huge amount” of effort into their presentations.

And that’s why we love these lists of ready-made, free Google Slides themes. Each and every one can help cut back on the effort required, while still ensuring your presentation has a top-notch aesthetic. 

The free Google Slides themes above will save you time, and offer you a boost in quality and flexibility. This is especially important if design is not your strong suit, or you simply don’t have the bandwidth to create something of your own. 

If you do have some prior experience with design, but still want to start with something that’s close to finished, it’s also good to know that Google Slides have recently added new design-savvy features to their themes. Now, users can apply a modern vector engine, to create highly customized layout designs.

To wrap this all up, it’s also important to remember that presentations are about more than just conveying information. A great presentation — both in terms of content and design — shows your audience that you are a subject expert, have keen attention to detail, and stellar organizational skills. 

After all, when your presentation looks and flows well, you bring everyone else along in the journey.
