To outline text in Google Slides, simply open the Google Slides document > “Insert” > “Word Art” > write the text > enter. Outlining your text is a great way to add visual interest to your presentations and make them easier to read.
Use the desktop browser version of Google Slides for these steps. Word art outlines the letters themselves; a text-box border draws a rectangle around the whole box.
So let’s see how to do this:
Step 1: First, open the Google Slides document that you want to edit.
Step 2: Next, press “Insert” from the top menu and select “Word art”.

Step 3: Now you will see a box. Write the text you want to outline.

Step 4: Press Enter to place the Word art on the slide. Then, reposition it to your desired location.

Step 5: Select the Word art and use Fill color for the inside of the letters and Border color for their outline. Use Border weight to make the outline thicker or thinner. These controls are in the toolbar above the slide.

How To Add Outline to Text Box In Google Slides
You can also add outlines to the text boxes themselves in Google Slides with just a couple of clicks. Here are the steps:
Step 1: Open Google Slides and go to the slide with the text box. Then, click the edge of the text box to select the whole object.
Step 2: Click Border color in the toolbar above the slide and choose a color for the box outline.
Step 3: Use Border weight to change the line thickness and Border dash to choose a solid or dashed outline. Use Fill color if you also want to change the background inside the box.
