Why You Might Need to Extend a Power BI Page

The default 16:9 canvas size in Power BI is perfect for standard presentations and monitor displays, but it's not always the best fit for every data story. Extending your page vertically opens up a new world of design possibilities. It transforms your report from a static slide into a dynamic, web-like experience.

Here are a few common scenarios where a longer page is a superior choice:

• Detailed Tables and Lists: If you need to display a long table with many rows, like a product catalog, sales transaction history, or a lead list, forcing it into a small box with a scrollbar is clunky. An extended page lets the table breathe and allows users to scroll through the entire report naturally.
• Narrative Storytelling ("Scrollytelling"): You can guide your audience through a data narrative, revealing insights step-by-step as they scroll down. Start with high-level KPIs at the top, followed by more detailed breakdowns and supporting visuals below. This is far more engaging than asking them to click through five different tabs to connect the dots.
• Consolidating Related Content: Instead of having separate tabs for "Campaign Performance," "Ad Set Breakdown," and "Creative," you could have one long, cohesive report. This keeps related information in one place, making it easier for users to see the bigger picture without having to jump around.
• Mobile Optimization: Vertical scrolling is the most natural interaction on a smartphone. Designing long-form reports makes the mobile viewing experience significantly better since users are already used to scrolling through content feeds on their phones.

Understanding Power BI's Page Sizing Options

Before you can extend your page, you need to know where to find the right settings. All page size adjustments happen in the Format pane. When you're designing a report in Power BI Desktop, make sure no visuals are selected, and you'll see options for the page itself.

Click the paint roller icon to open the Format your report page pane. Here, you'll find two key sections: Page information and Canvas settings.

In Canvas settings, you’ll see a Type dropdown. By default, it's set to 16:9, which gives you a canvas that is 1280 pixels wide and 720 pixels tall. Power BI also offers a few other presets like 4:3 (better for tablets) and Letter (for print-optimized reports), but the real power lies in the Custom option. This is the setting we'll use to break free from the standard dimensions. When you select Custom, you unlock the ability to manually enter a specific Height and Width in pixels.

After adjusting the canvas size, the next essential step is managing the Page View. In the Power BI Desktop ribbon, under the View tab, you have a few options:

• Fit to page: This is the default. It shrinks or stretches your report to fit entirely within the window. For a very long page, this will make everything look tiny and unreadable.
• Fit to width: This option scales the report so its width matches your screen, adding a vertical scrollbar if the page is taller than the window. This is the optimal setting when designing and viewing extended pages.
• Actual size: This shows the report at its true pixel dimensions. This is also useful for design, as it shows you exactly what the user will see without any scaling.

Forgetting to adjust the Page View is the number one reason people get stuck. If you extend your page but leave the view on "Fit to page," you won't see a scrollbar and will be left wondering why your amazing long-form report just looks like a miniature version of a regular report. Change your view to Fit to width to see the scrollbar appear and interact with your extended canvas correctly.

Step-by-Step Guide: How to Extend Your Power BI Page

Ready to create a long-scrolling report? The process is incredibly simple. Just follow these steps.

Step 1: Open Your Report in Power BI Desktop

Start a new report or open an existing one that you want to modify. Click on a blank area on the report canvas to ensure no visuals are selected.

Step 2: Access the Canvas Settings

In the Visualizations pane on the right-hand side, click the Format your report page icon (the paint roller). This will open up the formatting options for the entire page.

Step 3: Switch to a Custom Page Size

Expand the Canvas settings section. Here, you'll see a dropdown menu labeled Type. Click it and change the selection from the default (usually 16:9) to Custom.

Step 4: Define Your New Page Dimensions

Once you select Custom, two new input boxes for Height and Width will appear. To create a vertically extended page, you primarily need to increase the Height. The standard 720-pixel height is often too short. For a report you expect users to scroll through, try something like 2000 px or 3000 px to start.

You can adjust the Width as well, but it's generally best to keep it around the standard 1280 pixels to avoid forcing users into an awkward horizontal scroll.

Example Custom Dimensions: Height: 2500 px Width: 1280 px

Step 5: Adjust Your Page View for Optimal Editing

As mentioned earlier, this step is critical. Navigate to the View tab in the top ribbon menu. Under the Page View group, select Fit to Width. Immediately, your design canvas will zoom to fit the width of your screen, and you'll see a vertical scrollbar appear on the right side. You can now scroll down and begin adding visuals to your newly extended workspace.

Best Practices for Designing Long Pages

Having a virtually infinite canvas is great, but it requires mindful design to be effective. A poorly structured long page can be just as confusing as a report with too many tabs. Here are some tips to create a great user experience.

• Guide the User's Eye: Use clear text headers, dividers, and background-colored sections to organize your report. This creates a logical flow and prevents the page from feeling like a single, overwhelming wall of charts.
• Keep Critical KPIs "Above the Fold": Place your most important, high-level metrics at the very top of the page. This is the information a user can see without scrolling. Reserve the more granular, detailed visuals for the sections further down the page.
• Use Bookmarks for On-Page Navigation: For very long reports, use Bookmarks and Buttons to create a table of contents at the top. You can create a button that says, for example, "Jump to Regional Sales," which, when clicked, instantly scrolls the user down to that specific section of the report. This is a powerful feature that makes navigation effortless.
• Monitor Performance: Remember that every visual on your page sends a query. Loading a single page with 50+ visuals will be slower than loading a page with 10. While extending your canvas is great for layout, don't go overboard. Streamline your DAX measures and be selective about how many visuals you place on one page to maintain a snappy, responsive report.

Common Mistakes to Avoid

As you get the hang of extending pages, here are a few common pitfalls to steer clear of:

• Forgetting About Page View: It's worth repeating - always switch your page view to "Fit to Width" or "Actual Size." You cannot properly design or view a long-form page with the default "Fit to Page" setting.
• Going Too Wide: Unless you have a very specific use case, avoid creating extra-wide pages. Most people use widescreen monitors, and forcing them to scroll left and right is a frustrating experience. Prioritize vertical scrolling.
• Lacking Structure: Don’t just dump visuals randomly onto your extended canvas. Think like a web designer. Use white space, alignment, and clear headings to create a clean, professional, and easy-to-follow layout from top to bottom.

Final Thoughts

Extending a Power BI page is a straightforward tweak that completely changes how you can present data. By switching to a custom canvas size and embracing vertical scrolling, you can build more intuitive reports, tell deeper data stories, and finally make room for all the insights you want to share. It's a simple skill that elevates your dashboard design from good to great.
