How to Change Text Box Border Thickness in Word on Mobile
Product
Microsoft Word
Device & OS
Android / Mobile
Scenario
Formatting text boxes and shapes within a Word document using a smartphone or tablet.
Observed behavior
Word for Android and other mobile platforms does not expose the settings to change text box line weight that are available in the desktop version.
Before you start

Ensure your document is saved to a cloud service like OneDrive or Google Drive so you can easily access and edit it from a computer or web browser.

Solution 1Recommended

Use Desktop Word or Word for the Web

Since the mobile version lacks line-weight controls, opening the document on a desktop or web version of Word is the most effective way to apply these formatting changes.

Microsoft limits advanced formatting tools in its mobile applications to prioritize lightweight reading and basic editing. To access full shape formatting features, you must transition to a full desktop environment.

1
Save to the cloud

Make sure your current document edits on your mobile device are fully synced to OneDrive or your preferred cloud storage provider.

2
Open on a computer

Access the document using the Microsoft Word desktop application on your PC or Mac, or log into Microsoft 365 on a web browser to use Word for the web.

3
Select the text box

Click directly on the edge of the text box you wish to modify so that it is highlighted.

4
Adjust the outline weight

Navigate to the 'Shape Format' tab on the top ribbon, click 'Shape Outline', select 'Weight', and choose your desired border thickness.

Use Desktop Word or Word for the Web
Automatic Syncing: Once you save the changes on your desktop or web version, the updated border thickness will display correctly the next time you view the document on your mobile device.

Frequently Asked Questions

Can I remove the text box border entirely on the Word mobile app?

Removing the border entirely may also be restricted depending on your specific app version. If the 'No Outline' option is missing from your mobile tool palette, you will need to remove it using a desktop or web version of Word.

Why does Word for Android lack text box formatting features?

Microsoft has designed its mobile applications to be streamlined for basic text editing and reading. Advanced formatting tools like specific shape outline weights take up interface space and are currently reserved for the desktop and web environments.

Are there any add-ins for Word mobile that fix this issue?

No, add-in support for Word on Android and iOS is highly limited and generally does not extend to modifying core UI features like shape formatting menus. A desktop environment is required for these changes.
