How to Fix Excel on iPad Changing Paper Size to Legal When Printing
Question details
Users experience an issue where Excel spreadsheets printed from an iPad or iPhone automatically change the paper size from Letter to Legal after tapping Print.
- Product
- Microsoft Excel for iOS
- Device & OS
- iPadOS / iOS
- Scenario
- Attempting to print an Excel spreadsheet to a printer that defaults to Letter size from an Apple mobile device.
- Observed behavior
- The print preview initially displays Letter size, but forcefully changes to Legal size when the Print button is selected, causing incorrect printouts.
Ensure your printer has Letter-sized paper loaded, is connected to the same Wi-Fi network as your iPad or iPhone, and has the latest firmware installed.
Use a Third-Party Printer App (Workaround)
Bypass the native iOS print dialog by sharing the spreadsheet directly to your printer's dedicated companion app.
Since this issue appears to be a bug within the Excel app's communication with the native iOS print spooler, routing the print job through a dedicated printer app avoids the unprompted paper size change.
With your spreadsheet open in Excel, tap on 'File', then select 'Share', and choose 'Send To'.
From the list of available apps, tap on your printer manufacturer's app (e.g., 'Print with HP Smart', 'Epson iPrint', or 'Canon PRINT').
Verify that the paper size says Letter inside the third-party app's print preview, then tap Print to finalize.
Troubleshoot and Reinstall the Excel App
Verify if the issue is isolated to a specific workbook or app version, and perform a clean reinstallation.
Report the Issue via Help and Feedback
Notify the development team about the bug to expedite an official patch in a future update.
Print Spreadsheets Accurately on iOS with WPS Office
If you are experiencing persistent printing bugs in Excel for iOS, consider switching to WPS Office. It is a free, highly compatible alternative that processes document formatting and paper sizes accurately on iPads and iPhones.
- 1. Download the app: Install WPS Office for free from the App Store on your iPad or iPhone.
- 2. Open your file: Locate and open your existing .xlsx spreadsheet directly within WPS Office without losing any formatting.
- 3. Print the document: Tap the Tools menu, select Print, verify the Letter size in the preview, and print seamlessly.

Frequently Asked Questions
Why does my iPad change my Excel print size to Legal?
This is a known bug within the Microsoft Excel app for iPadOS and iOS. The app's communication with the iOS print spooler sometimes defaults the output format to Legal size right after the print command is initiated.
Does this printing issue affect Excel on Windows or Mac?
No, this specific paper size change issue is isolated to the mobile app versions on iPadOS and iOS. Printing the exact same document from a Windows PC or a Mac typically defaults to Letter and prints correctly.
How can I permanently fix the paper size issue in Excel for iOS?
Because this is an app-level behavior, a permanent fix relies on Microsoft releasing an update via the App Store. In the meantime, using a third-party printer app (like HP Smart) as a workaround is the most reliable solution.
