Sharepoint Form Width for List(Sharepoint Online)

New Contributor

The width on the default sharepoint form has changed automatically on my sharepoint site.  How do I revert the change?  Previously the form was on the right hand side of the screen and was about 1/4 of the screeen, currently it takes up 9/10 of screen.  The form only has 8 fields.

Was your form customized with PowerApps or with JSON Form Formatting?
There was some JSON formatting that I deleted that resolved the issue. I did not customize the JSON formatting is there a setting/bug that would automatically create JSON formatting?

Thanks for the help.

@Beau Cameron I am also having the same issue as the OP.


Yes, I went into Power Apps but did not save anything (or at least that is what I thought). Now, the form is way too wide and I cannot see any way to correct this. Unlike the OP, there is no custom JSON showing within the form in Lists.


How do I revert the form to the default size? Any advice you can provide would be appreciated.

Hi @Beau Cameron , I am facing the same issue. I have applied JSON formatting for my forms . Is there any issue if I apply JSON formatting. All of sudden the width got changed.
