Office has a new default theme​

We’ve refreshed the Office theme with a new default font, color palette, style, and line weights that help you make your documents more modern and accessible.

Default font-Aptos​

We released 5 Calibri replacement candidate fonts to see what you thought:
  • Bierstadt
  • Grandview
  • Seaford
  • Skeena
  • Tenorite
You chose Bierstadt as the preferred font, and we gave it a new name, Aptos.

It supports a variety of weights and includes variants such as narrow, serif, and monospace.

Color palette​

We also researched popular color palettes and design trends, and created a set of default colors that works well in all Office apps. It helps you easily create accessible content. You can use these new colors to style content such as charts, lists, and shapes.

Default outline weights​

We have increased the default outline weights, improved the consistency between shapes and lines, and added better contrast.

Default Styles – Word​

We are refreshing the default style of our Word documents and Outlook emails to make them easy to read, look more professional, and easy to navigate.

How it works​

As the theme rolls out, all new documents, presentations, worksheets, and emails you create in Word, PowerPoint, Excel, and Outlook will use the new theme. You don’t have to do anything!

NOTE: Your existing documents won’t change. They will continue to use the original theme that was applied when they were created.

Tips and tricks​

  • Love Calibri? You can still use the previous Office theme. It’s been renamed Office Theme 2013 – 2022.
  • If neither Aptos nor Calibri are the right fonts for you, there are hundreds of other great choices built into Microsoft 365. Choose a typeface that matches your needs and set it as your default. Learn how.
  • Want to revert to older style formatting? You can use Word 2013 formatting from the Document Formatting.


This feature is available to Microsoft 365 Insiders who are running:
  • Win32: Version 2308 (Build 16701.20000) or later
  • Mac: Version 16.76 (Build 23070400) or later
  • Android: Version 16.0.16701.20000 or later
Coming later to iOS.

Don’t have it yet? It’s probably us, not you.​

Features are released over some time to ensure things are working smoothly. We highlight features that you may not have because they’re slowly releasing to larger numbers of Insiders. Sometimes we remove elements to further improve them based on your feedback. Although this is rare, we also reserve the option to pull a feature entirely out of the product, even if you, as a Microsoft 365 Insider, have had the opportunity to try it.


We love hearing your feedback!

On our web apps, click the Give Feedback to Microsoft button and include #OfficeTheme in your feedback. On our desktop apps, send feedback from the app by selecting File > Feedback on Windows or Help > Feedback on Mac. For Android, please tap Settings > Send Feedback  to submit your thoughts about this feature.  Choose I like something, I don’t like something, or I have an idea. We look forward to hearing from you!

The latest Office Suite updates completely changed the theme colors and users aren't happy about it
Microsoft updated the color layout of its Office products with the 2023 version of Suite, and it left some color palettes such as yellow behind, with the themes of the Office Suite being particularly impacted by these changes.

The changes were many and wide across the all-encompassing platform: not only did the themes suffer from them, but the default font changed as well.

The old Calibri was replaced with the new Aptos, the table styles in Excel were replaced with new versions, and many users, rightfully so, felt overwhelmed by them.

There is good news and bad news about these changes: the good news is that you can revert the theme to its standard version, but the bad news is that the reverse is only supported by a few apps, such as Word, and PowerPoint. You can sort of revert to the standard version in Excel, as well, but it’s more complicated.
