Bug: Custom SharePoint List Form doesn't fit screen height (on external monitors/larger screens)

Hi there,

I have run into this issue every time I customize SharePoint List forms in Power Apps. When viewing the custom form on a monitor or larger screen, the form height looks so tiny and doesn't fill the whole pane like the default SharePoint List form does.

When looking in the Power Apps settings, it says the height is a static 720px instead of the browser window height (100%). When I put a higher number than 720px, it puts a scroll bar on medium-sized laptops/smaller devices. So I have to compromise with a tiny form that doesn't even fit the window like the native SharePoint form does.

Is there anyway to set the app height to 100% to fill the whole SharePoint form window?  I'm surprised this hasn't been fixed already by default.

It seems like there might be some kind of issue with how the app is formatted overall. I am not certain exactly what is causing the error here. This might be a better question for the Microsoft Support team. I'll include a link on creating a ticket with them if you would like to go down that route. Otherwise if any other communities member might know feel free to chime in.

Thanks for your response! Unfortunately, I don't have access to admin center to submit the ticket as I'm not a system admin.

However, I can confirm that this is an issue by default. I just created a brand new test list and tested customizing the form with PowerApps. And that form does the same thing. It's because there's no way to set the app height to 100%, by default the app height is set statically to 720px. So on modern standard screen resolutions on external monitors, the app appears so small.

If we can't set the App Height in settings to 100%, is there anyway to dynamically set the App.Height to 100% of the browser height via code? It's ridiculous how the form is a set height in pixels and not dynamically set when every other Microsoft app/service doesn't have this issue.

I'm having the same issue. Is there any fix for this or is Microsoft working on anything to make powerapps forms look like the default sharepoint forms and fill the page properly?
