How to change font on Macbook (Font Size, Font Style)

Accessibility has been a priority for Apple and other major tech brands in recent years, trying to cater to those that are hard of hearing, older people, and those that need assistance reading.

Part of tackling this is allowing macOS users to be ablt to change the size of their font so they can read the screen easier – here’s how you can do this.

Changing Font Size on Macbook Quickly via Accessibility

In macOS Sonoma and newer, it’s actually even easier for you to change the font settings on your Macbook.

First, we need to simply click on System Settings, and then go into Accessibility.


Then, scroll down and you’ll see the Display section. You have the option here to change text size based on your own preference, which will work with all supported apps.

You can actually edit this for individual apps too, so you could have your Mail app in 20px whilst having your Calendar app text size as 16px.


You can also change the size of your Menu bar to large, or opt to prefer horizontal text (this is mainly used for languages that support this, like Korean).

You will not be able to do this on older versions of macOS, but there are other ways that you can change your font size if you need to.

Changing Font Size via Display

Another way that you can change the size of the text on your Macbook is by changing the display resolution to make it more of less scaled.

This can be necessary, especially if you’re connecting your Macbook to an external monitor that uses a different resolution than the default of your Macbook.

The Displays option is also available from the same page within System Settings. You have the option to switch from Default to having larger text, which is great if you have poor eyesight and need your words a little bigger.


Can you change font style on Macbook?

One fairly common question people have is whether they can change the font style on Mac to an alternative. macOS used SF Pro, which some people find a little difficult to read.

Unfortunately, there’s no way to do this natively within macOS. The best option is to use a third party software or application, though they may not change the font in all of your applications.

Some examples of these apps are;

  1. TinkerTool: TinkerTool is a popular application that gives you access to additional preference settings Apple has built into macOS. It allows users to customize the system fonts among many other features.
  2. Font Book: While Font Book is not a third-party app (it’s included with macOS), it is a powerful font management tool. It doesn’t directly change system fonts, but it can be used to manage and install new fonts for use in various applications.
  3. LiteIcon: LiteIcon is a simple app which allows you to change your system icons quickly and easily. While primarily focused on icons, it offers some options for font customization.
  4. ThemeEngine: For more advanced users, ThemeEngine allows editing of the .car files that contain the UI resources for macOS, including fonts. This is for advanced users and can be risky if you’re not sure what you’re doing.

Remember, using third-party applications to modify system settings can sometimes lead to unexpected behavior or stability issues.

Always make sure you have a current backup before making substantial changes to your system, especially when using tools like ThemeEngine that modify system files directly.


All in all, there are various different reasons why you may want to change your font size on Macbook. Hopefully, within the options you find within your System Settings, you’ll be able to find an option that works for you.
