Power BI export does not fill up PowerPoint slide
Whenever I export a PPT from Power BI (online workspace or app), the PPT static image does not fill up the entire PowerPoint slide.
I can really notice when I use a background. And it doesn't matter if I use FIT, STRETCH, or FILL options. The image never fills up the entire PPT slide. Is there a way to fix this?
I'm attaching a sample background, and a snippet of the issue from the PPT slide (image does not fill entire slide, surrounding white/empty gap).

Edit: Canvas setting is 16:9.

Edit2: Just to make it more clear, I added some random blue shapes in Power BI (not directly onto the image). The Power BI page does not reach the edge of the PPT slide when exported on the left side, the bottom, and the right side. The top side seems to reach the top (enough).

From the comments provided by other users and my testing, it looks like there is padding added to the bottom of the image that is exported. It does not appear that there is padding on the sides. It appears like a white margin/border because
- the bottom padding is white
- This can be controlled/changed with FORMAT PAGE > WALLPAPER > COLOR
- In my report, the bottom border of my background/report is gray, so I made the wallpaper gray to make the padding look like it matches and is part of the background border.
- there is a gap (left/right) between the exported image and edge of the PPT slide which reveals the PPT slide color.
- If you change the PPT slide color, the left/right gaps that look like a border/margin will be the PPT slide color.
- I'm using VERTICAL ALIGNMENT > TOP.
- Your results might be different if you use MIDDLE.
- I don't know if that changes the padding behavior (on top) or dimensions below.
Through trial and error, I was able to minimize the left/right gap with dimensions of 716px x 1292 px on most pages. For some unknown reason, at least one page required different dimensions. These dimensions might not work for you, as other dimensions were suggested to me (see links below). So you might need to do your own trial and error.
Also note that the arrangement/positions of your visualizations might shift from Power BI to PPT export. In other words, on at least one page, my visualizations are perfectly aligned in Power BI, but they are shifted and unaligned in the PPT export. I don't know whether or not this is related to the dimension changes or Power BI export padding.

You need to match report canvas exactly to PPT slide. Always use use 16:9 canvas and avoid custom page sizes.
Hi user01
Thank you for reaching out to the Microsoft Fabric community forum.
The issue happens because Power BI adds internal padding and DPI scaling when exporting report pages to PowerPoint, even if the canvas is set to a 16:9 ratio. This causes small gaps on the sides and bottom of the PowerPoint slide. It’s a known limitation and not due to background image fit settings. To fix this, try setting the report canvas to a custom size slightly larger than 16:9, such as 1284 × 724 pixels. This helps the image fill the slide completely. You can also check the Power BI community thread https://community.fabric.microsoft.com/t5/Service/White-margins-exporting-PPTX-in-PowerBI-Service/m… for more details and solutions.
