How to Expand Power BI Page

Ever felt like you were trying to fit a feature-length film onto a single index card? That's what it can feel like trying to build a comprehensive dashboard on a fixed-size Power BI page. The good news is you're not stuck with the default dimensions. This article will walk you through exactly how to expand your Power BI page to create longer, scrollable reports and give your data the breathing room it deserves. We'll also cover some best practices for designing on a larger canvas.

Understanding Why You Need a Bigger Canvas

The standard 16:9 Power BI canvas is great for slide presentations or a standard monitor, but it quickly becomes restrictive. You might need to expand your page for several common reasons:

• Creating "scrollytelling" reports: You want to guide your audience through a data narrative, starting with high-level KPIs at the top and drilling down into more granular details as they scroll. This is perfect for deep-dive reports on marketing funnels or sales pipeline performance.
• Accommodating lots of visuals: Sometimes, you just need to display a dozen different charts, tables, and KPIs on a single page without making everything tiny and unreadable. A taller page lets you stack visuals logically.
• Designing for specific displays: You might be creating a dashboard for an extra-wide monitor in the office or a vertically-oriented screen, requiring custom dimensions.
• Migrating from older reports: If you're recreating a long-form Excel report or a report from another BI tool, you'll need a canvas that can match the original layout without compromise.

Whatever your reason, changing the canvas size is a straightforward process that unlocks a ton of flexibility.

How to Expand Your Power BI Page Canvas

Changing the dimensions of your report page is done right inside Power BI Desktop. The options are a bit tucked away, but once you know where to look, you'll find it's only a few clicks away.

Step-by-Step Guide to Resizing Your Canvas

Follow these simple steps to customize your page size:

1. Open Your Report: Launch Power BI Desktop and open the report file you want to edit.
2. Select the Page Canvas: Click on any empty space on the report page you wish to resize. This is an important step - if you have a visual selected, you'll see formatting options for that visual instead of the page itself.
3. Go to the Format Pane: With the canvas selected, look to the Visualizations pane on the right side of the screen. Click on the paintbrush icon labeled "Format your report page."
4. Open Canvas Settings: In the Format pane, you'll see a list of formatting options. Click on "Canvas settings" to expand its menu.
5. Choose Your Type: Under "Type," you'll see a dropdown menu. The default is typically "16:9" (a widescreen format). Click this dropdown to see other presets like 4:3, Letter, and Tooltip. For a custom size, select Custom.
6. Set Your New Dimensions: Once you select "Custom," input boxes for Height and Width will appear. Enter your desired dimensions in pixels. For a long, scrollable report, you might keep the width at 1280 pixels but increase the height to 2500, 3000, or even more.

That's it! Your canvas will immediately resize, and you'll see a scrollbar appear if your content exceeds the viewable area. You can now start adding more visuals or rearranging existing ones to take advantage of the new space.

Tips for Designing on an Expanded Canvas

More space is great, but it can also lead to cluttered, hard-to-follow dashboards if not used thoughtfully. Simply making a page longer isn't enough, you need to structure your visuals in a way that remains clean and intuitive.

Think in Sections, Not Just Stacks

A long, scrolling page can overwhelm users if it feels like an endless pile of charts. The best practice is to group related visuals into logical sections.

• Use headers: Add text boxes with clear headings for each section (e.g., "High-Level KPIs," "Channel Performance," "Audience Demographics"). This acts as a signpost telling users what they're looking at.
• Use shapes for grouping: A simple but powerful trick is to use the Shape visual. Add a rectangle, set its fill color to a very light gray or a slightly off-white, and send it to the back (Format > Bring forward > Send to back). Then, place a group of a few related charts on top of it. This visually contains the section and separates it from the rest of the report.

Maintain Spacing and Alignment

Negative space (the empty space between your charts) is one of the most important elements of dashboard design. With a larger canvas, it's tempting to cram things together, but this makes the report look chaotic.

• Leave consistent margins between all your visuals.
• Use the alignment tools available in the Format tab to keep everything neat. Select multiple visuals (by holding Ctrl and clicking them), then go to Format > Align and choose options like "Align top" or "Distribute horizontally."

Don't Forget the Viewport

Your users will only see a portion of your page at one time. This "viewport" is what's visible on their screen before they scroll. Always place your most critical, summary-level information at the very top of the page so it's impossible to miss.

Then, arrange the rest of the report in order of decreasing importance or as a logical narrative. Ask yourself: if a user only looks at the first screen and never scrolls, what is the single most important takeaway you want them to have?

An Alternative Approach: Using Bookmarks to Manage Space

Sometimes, creating a long, scrollable page isn't the best solution. You might have several different groups of data you want to display, but they don't necessarily fit into a top-to-bottom narrative. In this case, you can use Bookmarks to create different "views" on a single, standard-sized page.

Think of it as creating interactive tabs on your dashboard. You can create buttons that show or hide different sets of visuals, allowing you to pack twice the information into the same amount of space without any scrolling.

How to Set it Up Quickly:

1. Go to the View tab in Power BI Desktop and check the boxes to open the Bookmarks and Selection panes.
2. In the Selection pane, you'll see a list of all visuals on your page. Rename them to be descriptive (e.g., "Sales Trend Chart," "Marketing ROI Table"). You can toggle their visibility using the small eye icon next to each one.
3. Arrange your "primary view" of charts on the canvas. Hide all the visuals for your "secondary view." Now, in the Bookmarks pane, click Add and rename this bookmark to "Primary View."
4. Next, hide the visuals for your primary view and show the ones for your secondary view. Add another bookmark and name it "Secondary View."
5. Finally, add buttons to your page (Insert > Buttons). With a button selected, go to the Format pane, turn on the "Action," set the Type to "Bookmark," and choose the corresponding bookmark from the dropdown.

Now, users can click the buttons to seamlessly toggle between the different sets of charts on your page. It's a clean, professional way to handle high-density reports without asking users to scroll.

Final Thoughts

Mastering page sizing in Power BI is a simple but essential skill that lets you break free from restrictive layouts. By changing your canvas to custom dimensions, you can build long dashboards perfect for data storytelling. Combining this technique with smart design principles like sectioning and alignment will help you create reports that are not only comprehensive but also clear and easy to navigate.

Building dashboards can often involve a learning curve and many rounds of tweaking visuals and layouts until they’re just right. This is one of the reasons we designed Graphed to work conversationally. Instead of manually adjusting canvas settings and dragging visuals around, you can simply ask in plain English, "Show me my top 10 products by revenue last quarter in a bar chart," and it builds the visualization for you, instantly. It automates away the setup so you can focus on the insights.
