You can change the size of the list form via File > Settings > Screen size + orientation.

Switch Size from “Custom” to “Small” or “Large” and the list form should be in the auto resize mode.

Reference: Customize a SharePoint list or library form by using Power Apps (Further customize your form).

Here’s another post with detailed information on custom list form for your reference:

Increase the width of the power apps forms and add header.

  • @AakashMaurya The setting is available when customizing default SharePoint list form. However, there doesn’t seem to be any official statement about PowerApps working in high resolution devices. You can check out this post and see if you can get custom form height to work with Flexible Height Gallery: powerusers.microsoft.com/t5/Building-Power-Apps/… Commented Mar 17, 2020 at 8:40
