When you open Microsoft PowerPoint, by default, thumbnails of the slides appear in the left pane. In PowerPoint, you can hide, view, or even change the size of these thumbnails. Here's how.
Everyone has a different style of working. Some may prefer to keep the thumbnails of the slides in order to create an outline, or simply navigate between the slides when editing. However, some may find it distracting or obtrusive, and as such, want to hide or reduce their size. Both are relatively easy to do.
Open PowerPoint. By default, you should be in normal PowerPoint view mode. If not, go to the View tab and click the Normal button.
In Normal view, the thumbnails of the slides are displayed on the left side of the window.
To reduce the size of thumbnails, click on the separator bar and drag to the left.
The further you drag the splitter bar to the left, the smaller the thumbnails become. To completely hide the thumbnails, drag the bar to the left until they disappear.
If you have hidden the thumbnails but need to see them again, click the arrow above. "Thumbnails" on the left side.
To zoom in on the slide thumbnails, click on the separator bar and drag to the right.
Another way to change the size of the thumbnails is to move the pointer over the thumbnail preview window and then use the mouse wheel while holding down the Ctrl key. However, you can not completely hide the thumbnails with this method.
Changing the default view of PowerPoint
If you frequently hide the thumbnails of slides while working in PowerPoint, you should change the default view in which PowerPoint opens.
To go to the "File" tab, then select "Options" at the bottom of the left pane.
The PowerPoint Options window appears. Select "Advanced".
Scroll down to the "Display" section and select the arrow next to "Open all documents with this view" to display the menu options.
Select the view style you want to use by default in the menu. There are many different options to choose from, some of which do not contain thumbnails.
Finally, click "OK" to confirm the change. PowerPoint opens the next time you use it in the selected view style.
