Maira MehtabMaira Mehtab Sep 21, 2026 869 views

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.
Before you start

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.

Solution 1Recommended

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.

1
Open the Share menu

With your spreadsheet open in Excel, tap on 'File', then select 'Share', and choose 'Send To'.

2
Select your printer app

From the list of available apps, tap on your printer manufacturer's app (e.g., 'Print with HP Smart', 'Epson iPrint', or 'Canon PRINT').

3
Print the document

Verify that the paper size says Letter inside the third-party app's print preview, then tap Print to finalize.

App Requirement: You must download and set up your printer manufacturer's official app from the App Store beforehand for this option to appear in the share menu.

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.
