How to Increase a Multiline SharePoint Text Field Height

Product: SharePoint
Device & OS: not provided
Scenario: Editing list items in SharePoint where the default multiline text field appears too short to comfortably view long text.
Observed behavior: The standard SharePoint text field lacks a permanent height configuration in default settings, though it may expand or allow manual resizing during active entry.

Before you start

Verify whether you have permission to customize SharePoint list forms, as making permanent layout changes to the form requires Power Apps access and appropriate site privileges.

Solution 1

Manually Resize or Auto-expand the Text Field

Use built-in browser features or SharePoint's default behavior to temporarily expand the text box while you are editing an item.

By default, standard SharePoint list forms do not offer a permanent height setting for text fields, but they provide temporary ways to view more text.

Enter text to trigger auto-expand

Click inside the multiline text field and begin typing. In modern SharePoint experiences, the text box will often automatically expand downward to accommodate your new text.

Drag the resize handle

Look for a small drag handle (usually represented by diagonal lines) in the lower-right corner of the text field. Click and drag this handle downward to manually increase the height of the box.

Solution 2Recommended

Customize the List Form with Power Apps

Modify the list form using Power Apps to permanently set a taller default height for the multiline text input control.

Solution 3

Submit a Feature Request to Microsoft

If you cannot use Power Apps and need a native default height setting, submit feedback to the SharePoint development team.

Frequently Asked Questions

Can I change the default height of a SharePoint multiline text field without Power Apps?

In modern SharePoint lists, there is no out-of-the-box setting to permanently define the height of a multiline text field without using Power Apps. You can only rely on the field's auto-expand behavior or manual resizing via the corner handle during active entry.

Why is the manual resize handle missing in my SharePoint text field?

The appearance of the resize handle often depends on the specific web browser you are using and whether the field is rendered in a classic or modern SharePoint experience. Ensure your browser is up to date, or try switching to modern list views.

Will modifying the form in Power Apps affect other users?

Yes, once you customize a SharePoint list form using Power Apps and publish it, the new layout and field dimensions will be applied for all users who have access to create or edit items in that list.
