How to Fix OneNote Changing Open Sans Light to Calibri on Another Computer

Product: Microsoft OneNote
Device & OS: not provided
Scenario: Opening, viewing, or sharing a OneNote notebook on a different computer that does not have the originally used fonts installed.
Observed behavior: OneNote automatically replaces the Open Sans Light font with Calibri, which changes text spacing, misaligns annotations, and alters the document layout.

Before you start

Verify if you have administrator privileges on the destination computer, as installing new fonts requires admin rights on most Windows systems.

Solution 1Recommended

Install the Missing Open Sans Light Font

Manually installing the missing font ensures the target computer can correctly render the text without substituting it with Calibri.

When a specific font is not present in the system's font library, OneNote falls back to a default system font. Installing the exact font file used in the original document is the most reliable way to maintain your intended layout.

Download the font file

Obtain the 'Open Sans Light' font file (usually ending in .ttf or .otf) from a trusted font provider or copy it from the original computer's font directory.

Install the font

Right-click the downloaded font file and select 'Install' or 'Install for all users' from the context menu.

Restart OneNote

Close Microsoft OneNote completely and reopen it to allow the application to recognize the newly installed font.

Verify the formatting

Open your notebook again. The text should now display correctly in Open Sans Light, restoring the original spacing and layout.

Administrator Rights Required: If you are using a school or corporate computer, you may need to contact your IT department to authorize and install the font for you.

Frequently Asked Questions

Why does OneNote change my fonts automatically?

OneNote changes fonts automatically when it detects that the document uses a font not currently installed on the device. To ensure the text remains readable, it substitutes the missing font with a default system font like Calibri.

Can I embed fonts directly into a OneNote notebook?

Unlike Microsoft Word or PowerPoint, OneNote currently does not have a built-in feature to embed fonts within the file itself. To prevent formatting changes, the required font must be manually installed on every viewing device.

Where can I find a list of standard fonts that won't change?

You can find the official list of universally supported standard fonts on the Microsoft Learn website under the Windows 11 font list documentation. Using these standard fonts ensures your notes display correctly on almost any updated Windows device.
