Step by Step Tutorial on How to Lock a Picture in PowerPoint

Before we get into the steps, let’s clarify what we’ll achieve. By following these instructions, you’ll ensure your picture stays put on the slide, maintaining its size and position regardless of other changes you make to your presentation. Let’s get started!

Step 1: Select the Picture

Click on the picture you wish to lock.

Selecting the right picture is crucial. Make sure you click on the image you intend to lock, as these settings will only apply to the image you choose.

Step 2: Access the “Size and Position” Dialog Box

Right-click on the selected picture and choose “Size and Position” from the context menu.

This step will open a dialog box where you can adjust various settings related to the size and position of your image.

Step 3: Lock the Aspect Ratio

In the “Size and Position” dialog box, go to the “Position” tab and check the box next to “Lock aspect ratio.”

By locking the aspect ratio, you’re ensuring that the image’s proportions remain consistent, preventing any stretching or squashing when resizing.

Step 4: Close the Dialog Box

Click “Close” to apply the settings and exit the dialog box.

After completing this step, your picture will be locked in place.

Additional Information

Now that your picture is securely locked in your PowerPoint presentation, it’s time to explore some extra tips to make your slides even more effective. First and foremost, remember that a locked picture can still be edited in terms of effects and styles; locking only affects the size and position. So feel free to get creative with borders or color adjustments!

Also, consider the overall design of your slide. A locked picture should complement the text and other elements, not overpower them. Use the ‘Arrange’ feature in PowerPoint to send the image backward or bring forward, ensuring it sits perfectly within your slide layout. If you ever need to unlock the picture to make adjustments, simply reverse the process – it’s just as easy.

Finally, think about the visual message you’re conveying. A locked picture can be a powerful tool to direct focus and maintain the audience’s attention where you want it. Use this feature wisely to enhance your presentation’s impact.


  1. Select the picture.
