How to Create a Fullscreen Popup in WordPress + 10 Real-World Examples
  1. Attention-Grabbing: Fullscreen popups demand immediate attention from your visitors by covering the entire screen. This makes them highly effective in delivering important messages or promotions, capturing user interest, and increasing engagement.
  2. Focused Messaging: With fullscreen popups, you have a dedicated space to communicate a specific message or call-to-action. This eliminates distractions and lets you present your content clearly and concisely, ensuring your visitors understand your message without interference.
  3. Maximized Conversion Opportunities: Fullscreen popups are powerful conversion tools. They can be strategically designed to capture leads, drive sign-ups, promote offers, or encourage purchases. By occupying the entire screen, these popups create a sense of urgency and encourage visitors to take action.
  4. Increased Visibility: Fullscreen popups are hard to miss. Since they cover the entire screen, they are highly visible and can effectively convey important information or updates to visitors. This ensures that your messages reach a wider audience and increases the chances of your visitors engaging with your content.
  5. Enhanced User Experience: When used thoughtfully, fullscreen popups can improve the overall user experience. For example, you can use them to provide valuable information, guide visitors to relevant content, offer personalized recommendations, or assist with onboarding processes. This helps your visitors navigate your website more effectively and enhances their satisfaction.
  6. Versatile Design Options: Fullscreen popups offer a wide range of design possibilities. You can customize their appearance to match your website's branding, use eye-catching visuals, incorporate animations, or include interactive elements. This flexibility allows you to create visually appealing popups that align with your website's aesthetics and attract attention.
  7. Segmented Targeting: Many popup plugins provide advanced targeting options, including the ability to display fullscreen popups to specific segments of your audience. This allows you to deliver personalized messages based on user behavior, demographics, or other criteria. Segmenting your popups ensures that your messages are relevant and resonate with your target audience.

Incorporating fullscreen popups into your WordPress website can greatly enhance your marketing efforts, improve user engagement, and drive conversions. By leveraging their attention-grabbing nature, focused messaging, and versatility, you can effectively communicate with your audience and achieve your website's objectives.

As you will notice, our popup does not have any content yet. We must add some content before proceeding to the next step. Let's add some dummy content for test purposes. For this example, we will add a simple Heading and Paragraph. Your popup's content should look like this:

Now if we test our popup, we will get a result like this:

As you can see, our popup does not cover the whole page; therefore is not considered a full-screen popup yet. We must change the popup's size to make it a full-page popup. To do so, go back to your WordPress dashboard, in the popup builder in the Design tab, and set the Width and Height options to 100%.

Click save and preview the popup once again. Now, the popup should cover the whole page. Congratulations! You've created your first WordPress full-screen popup.
