Effect of Changing Page Size on Visuals

You have a Power BI report page with several visuals arranged neatly. You change the page size from '16:9' to 'Letter'. What is the most likely visible effect on your visuals?

A Visuals automatically resize and reposition to fit the new page size without overlap.

B The page size change only affects export settings and does not change the canvas layout.

C Visuals keep their original size and position, causing some to be cut off or overlap.

D All visuals are deleted and need to be recreated for the new page size.

💡 Hint

Think about how fixed positions behave when the canvas size changes.

Changing the page size changes the canvas dimensions but does not automatically resize or reposition visuals. This can cause visuals to be cut off or overlap if the new size is smaller or differently shaped.

DAX Measure Impact on Canvas Size

You create a DAX measure that calculates total sales and add a card visual to your report page. If you change the page canvas size from '16:9' to 'Custom' with smaller dimensions, what happens to the card visual's display of the measure?

Power BI

Total Sales = SUM(Sales[Amount])

A The card visual scales down but still shows the full total sales value clearly.

B The card visual truncates the total sales value because of limited space.

C The card visual disappears because the measure is invalid on smaller canvases.

D The card visual automatically changes font size to fit the new canvas size.

💡 Hint

Consider how visuals behave when canvas size changes but measure values remain the same.

The card visual scales with the canvas but still displays the full measure value unless manually resized. The measure itself is unaffected by canvas size.

Optimizing Report Layout for Different Devices

You want your Power BI report page to look good on both desktop and mobile devices. Which approach best uses page layout and canvas settings to achieve this?

A Create a mobile-optimized layout using the Power BI mobile layout view, separate from the desktop layout.

B Use a single page with a fixed canvas size and rely on automatic scaling on mobile devices.

C Design the report only for desktop canvas size and let mobile users zoom and scroll manually.

D Create separate report pages with different canvas sizes and layouts for desktop and mobile, then use bookmarks to switch.

💡 Hint

Think about Power BI features designed specifically for mobile optimization.

Power BI provides a mobile layout view to create a separate optimized layout for mobile devices without affecting the desktop layout.

Handling Visual Overflow on Small Canvas Sizes

You have a report page with many visuals. When you reduce the canvas size, some visuals overlap or get cut off. What is the best practice to handle this situation?

A Delete some visuals to reduce clutter and fit the smaller canvas size.

B Manually resize and reposition visuals to fit the smaller canvas, or create multiple pages for different views.

C Leave visuals as they are; users can scroll horizontally and vertically to see all content.

D Increase the canvas size back to original and force users to use larger screens.

💡 Hint

Think about user experience and report design flexibility.

Manually adjusting visuals or splitting content across pages ensures a clean layout without overlap or cut-off, improving user experience.

Diagnosing Unexpected Blank Space on Report Canvas

You notice that your Power BI report page has unexpected blank space on the right side, even though visuals do not extend that far. Which setting is most likely causing this?

A The page background color is set to white, making blank space more visible.

B Visuals have hidden borders extending beyond their visible area, creating blank space.

C The report theme includes padding that adds blank space around visuals.

D The page size is set larger than the visible canvas area, causing extra blank space.

💡 Hint

Consider how page size and canvas dimensions relate.

If the page size is larger than the visible canvas, Power BI shows blank space where no visuals are placed.
