What is a PowerPoint theme?
A theme is a predefined set of colors, fonts, and visual effects that you apply to your slides for a unified, professional look.
Using a theme gives your presentation a harmonious appearance with minimal effort. For example:
When you add graphics (tables, shapes, and so on) to your slides, PowerPoint applies theme colors that are compatible with other slide elements.
Dark-colored text is shown on a light background (and vice versa), so that contrast is strong for ease of reading.
Here are four different themes applied to the same slide:
To choose a theme for your presentation
PowerPoint offers several preset themes. They are on the Design tab of the Ribbon on the left side.
Open a slide. On the Design tab, point at a Theme thumbnail to get a preview of how it would affect the look of your slide.
To see the full gallery of themes, click the More button:
When you find a theme you want, click its thumbnail to apply it to all slides in your presentation.
To customize a theme, see Create your own theme in PowerPoint.
What is a PowerPoint template?
A template is a theme plus some content for a specific purpose—such as a sales presentation, a business plan, or a classroom lesson.
So a template has design elements that work together (colors, fonts, backgrounds, effects) along with sample slides and boilerplate content that you augment to tell your story.
You can create your own custom templates and store them, reuse them, and share them with others. See Create and save a PowerPoint template.
You can also find hundreds of different types of free templates for PowerPoint that you can apply to your presentation:

Slides containing content
Here is an example of a one-slide template for an award certificate:
A template like this can include:
1 Subject-specific content, such as "Certificate of Achievement," "Soccer," and the soccer ball image. Generally this text or content is only editable from the slide master.
2 Background formatting, such as pictures, texture, gradient or solid fill color, and transparency. This example shows the light blue solid fill background.
3 Color, fonts, effects (3-D, lines, fills, shadows, etc.), and theme design elements (such as the color and gradient effects inside the word Soccer).
4 Text placeholders that allow people to enter unique information to customize the slide for their needs, such as "Player's name," "Name of coach," "Date of presentation," and any variable, such as the year.
