Looking to add a touch of personal branding or organization to your Google Slides presentations? You're in the right place. Customizing your slides' template allows you to maintain your corporate identity or personal style across all your presentations. Here's a step-by-step guide on how to add a custom template to Google Slides, ensuring your presentations always reflect your unique style.

Before diving in, remember that creating a custom template involves a bit of familiarity with the Google Slides interface. If you're new to the platform, it might be helpful to first explore its features and functions.

Preparing Your Custom Template
Your custom template should be a blank Google Slides file with your desired layout, color scheme, fonts, and other design elements. You can create this file from scratch or modify an existing Google Slides template.

Once you've designed your template, it's time to save it. Naming it something like "My Custom Template" can help you recognize it later. But don't be tempted to hit 'Save' just yet. We need to publish it as a web app first.
Publishing as a Web App

To share your template with yourself and others, you'll need to publish it as a web app. Here's how:
- Click 'Share' at the top-right corner of the screen.
- Under 'Who has access', choose 'Anyone with the link' or 'Public on the web'.
- Click 'Advanced', then under 'Owner settings', choose 'On - anyone, even outside your domain, with the link'.
- Click 'Save', then click 'Done'.
Getting the Template ID

Now, you'll need to copy the template's ID to use it as a master slide.
- In your browser's address bar, look for the long string of characters after 'https://docs.google.com/presentation/d/' and before '/edit'. This is the template ID.
- Copy the template ID. You'll use this later to set your custom template as the default.
Setting Your Custom Template as Default

With your template published and its ID copied, it's time to set it as the default. Here's how:
- Open Google Drive and search for 'Google Slides template gallery'.
- Click on 'Google Slides template gallery' and go to the 'Your themes' tab.
- At the bottom, click 'Create new theme'.
- Paste your template's ID in the 'ID' field, give your theme a name, and click 'Create'.
- To set it as the default, go back to the 'Manage themes' tab, click the three dots next to your theme, and select 'Set as default'.









Using Your Custom Template
Now that you've set your custom template, you can use it for new presentations:
- Open Google Slides and click 'Start a new presentation'.
- Your custom template will now be the default, so just click 'Blank' to start a new presentation with your custom template.
Congratulations! You've successfully added a custom template to Google Slides. The best part? Your customized slides will keep your presentations looking consistently professional and personalized. Happy presenting!
