Familiarity with the Best PowerPoint Slide Design Methods to Engage the Audience in Presentations
To create PowerPoint slides aimed at engaging the audience in a presentation, you must use a set of professional PowerPoint techniques to have an attractive and creative PowerPoint theme. Below, we will introduce you to the principles of PowerPoint design. Additionally, if you don't have the time or knowledge to create a specialized PowerPoint, you can download beautiful and professional PowerPoint templates from reference collections, such as the Minaro online store.

Customizing Slide Sizes In fact, a good PowerPoint sample adjusts the slide sizes according to the display screen. Some people use the default slide sizes, and when displayed on larger screens, the slide content appears very small. To customize the slide size, follow these steps:
From the top toolbar, click the Design tab.
Then, in the Customize section, select Slide Size.
From the dropdown menu, click Custom Slide Size.
A dialog box will open where you can select the height and width of the slide and then click OK.
To change the slide size, do so before adding any content or other elements to the PowerPoint, as resizing may distort the dimensions of all elements.

Using Slide Master One of the best principles of PowerPoint design is to customize the PowerPoint template before starting the design work, so there is no need to design each slide manually. You can do the design work in less time using the Slide Master:
From the top toolbar, click the View tab.
Then, from the Master Views section, click Slide Master.
Finally, make any changes you wish on the first or master slide and then click Close Master from the top toolbar.
Proper Use of White Space in Slides One of the most important tips for professional PowerPoint design is to create slides with white space and remove unnecessary visual and text elements. Creating slides with understandable and digestible space will help the audience better grasp important content, while filling the entire page with various elements and content leads to confusion and an ineffective presentation.

Choosing Colors According to the Topic According to color psychology, using relevant colors for slides will have a great impact on audience engagement. PowerPoint allows you to change the colors, so you can choose the color that suits your beautiful PowerPoint theme. To customize the PowerPoint color scheme, follow these steps:
In the PowerPoint toolbar, click the Design tab.
Then, from the Variants section, click the downward arrow.
From the dropdown list, select Colors and choose your desired color.
Adding Pictures to PowerPoint One of the simplest and most creative ways to design attractive PowerPoint slides is to add beautiful and understandable pictures. In fact, slides with only written content and no visual elements will quickly bore the audience, and they won’t be able to focus on the presentation. Therefore, use professional and relevant images to represent complex concepts. To add a picture to your PowerPoint slide:

From the top toolbar, click the Insert tab.
In the Images section, add the desired image to your slide.
After placing the image, the Format tab will open for you to customize the appearance of the image.
Choosing the Best Fonts for PowerPoint Since words have a great impact on conveying important ideas to the audience, it is essential to use readable and understandable fonts when writing slide content so that everyone in the presentation hall can easily read them. Some fonts are available by default in PowerPoint, and you can add your preferred fonts. To save a font, use the File tab and the Options section.
Adding Effects to PowerPoint One of the best PowerPoint slide design methods for engaging the audience is to apply effects to visual and text elements on the slides. However, you must use effects in moderation, depending on your audience. For example, if you're presenting to educated individuals, avoid excessive effects. However, if your audience consists of children, adding effects to images and content can make it more engaging. With animations, you can make elements enter the slide dynamically and draw attention away from unnecessary elements.

Using Infographics in PowerPoint Slides To better and more attractively display data in PowerPoint, use infographics and design user-friendly infographics that tell the story of your content to present data better to the audience.
Aligning Content and Objects in Slides One of the best PowerPoint design tips is to align the text and visual elements to make the content more engaging to the audience. Proper alignment of content will make PowerPoint slides more visible and engaging. To align objects, hold down the Shift key, select the objects, and click on them. Then, from the Shape Format tab, select Align or Distribute in the Arrange section, and choose the desired alignment.

Using the 5 * 5 Rule in PowerPoint Design One of the best PowerPoint slide design methods is to apply the 5 * 5 rule, which suggests that the content on each slide should be limited to five lines, with each line containing no more than five words. When entering information on slides, simplify complex data, summarize the text, and only include necessary and important information.
Designing PowerPoint Based on Presentation Time When creating a PowerPoint, always consider how much time you have for your presentation, as you are only allowed to present within the specified time. For example, for a thesis defense, you may have a maximum of 15 minutes, so downloading a 50-slide PowerPoint template would not be appropriate. Therefore, adjust the number of slides according to the presentation duration and focus on including the essential content to engage the audience.
Most people want to create an attractive and creative PowerPoint theme to make a successful impact on the audience and capture their attention. Therefore, we have introduced the most important principles and tips for PowerPoint design to help you create a beautiful and professional PowerPoint theme by using the best PowerPoint slide design methods for engaging the audience.
