How to Change Font Size in Yahoo Mail? Free & Easy Methods

If you think that the default message size of Yahoo Mail is putting too much strain on your eyes, don’t worry. I will teach you how to change font size in Yahoo Mail.

I will tell you exactly what in-app settings you need to toggle both the browser and your mobile device. Plus, explore some secondary tactics to gain the same effect.

How to Change Font Size in Yahoo Mail Website?

The steps that I am about to tell you can only be done from within the Yahoo webmail, so log in to your Yahoo account.

For a single email:

Step 1. Click on Compose to start a new message.

Step 2. Click on the AA icon, then select any one option from the list. (You can also change the Font type from these settings.)

The changes you make here only apply to this particular message that you are sending. If you want the changes to remain in place for all messages you compose in the future, you have to do the following.

Set a Default Font Size for All New Emails:

Step 1. Click on the Settings (⚙) cog icon (Located near the top right corner).

Step 2. Click on • • • More settings.

Step 3. On the Settings screen, switch to the Writing email tab.

Step 4. Look for the Default rich-text font, toggle the dropdown, and select the size you want.

There are six different options ranging from tiny to Huge. You can see a small preview signature window to get an idea about how the text will look after you change it.

Moreover, there is no Save button; the changes apply as soon as you select an option.

Note that this font alteration only affects the messages you compose; it does not change any of the menu fonts. Or any of the messages that you receive from other people.

Short Cut to Alter Yahoo Mail Font Size

This is not a Yahoo Mail setting but rather a browser behaviour that we are using to our advantage.

While you are logged into the Yahoo Mail website, you can Zoom In if you feel the text is too small or Zoom Out if you think smaller text is better.

To do this, hold the Ctrl key and tap the + key on the keyboard to increase the font size. Moreover, if you hold the Ctrl key and press the hyphen (-), it will reduce the font size.

Alternatively, you can hold the Ctrl key and scroll up or down with the scroll wheel until you find the perfect viewing experience. This is an easy method for anyone still confused about how to change font size in Yahoo Mail.

Depending on the browser you are using, it may also contain a small magnifying glass icon somewhere on the toolbar. You can also click on it to adjust the size.

These steps apply to all the elements on the page, so the menus, icons, images, text, and everything else will increase or decrease in size with the same proportionality. Moreover, this is the only way to successfully change font size in Yahoo Mail if you recently had to go back to Old Yahoo Mail

However, be careful while you use this approach, as you may end up overdoing the adjustment and instead make the Yahoo mail less legible than it was before.

Although modern browsers are intelligent enough to maintain the zoom settings even after you close them, you may want to make the font change more permanent. Dont worry, I will teach you exactly what you have to do.

How to Change Font Size in Yahoo Mail Via the Browser?

Every browser allows its users to decide how big or small the content should appear on the screen. So we can use this to make the Yahoo Mail app render the text and other details in a size we are comfortable reading.

Before you make any changes to the browser, I suggest that you create a new profile just for Yahoo Mail. In this way, any changes you decide to apply to the Yahoo Mail site will not distort the viewing experience of other websites that you visit.

Once you have made the profile for Yahoo Mail, go to the browser settings. Different browsers have slightly different UI elements. Here, I have tried to cover the most popular browsers. If you don’t find the browser that you use to access Yahoo Mail here, don’t worry. The settings are almost the same, so you will be able to follow the instructions.

In Chrome/Edge: Go to Settings > Appearance > Font size. For maximum control, go into Customize fonts and set a Minimum font size. This is a powerful feature that forces even the tiniest Yahoo Mail website text to become readable.

In Firefox: Go to Settings > General > Language and Appearance. Here you can set a default font size and, under the Advanced… button, set a Minimum font size.

Remember to use the same profile every time you access Yahoo Mail; otherwise, the changes we made won’t be of any use.

Many people also use Yahoo Mail on their mobile devices, and they may be curious if any settings can change the font size on those devices as well.

Can You Change Font Size in the Yahoo Mobile App?

Unfortunately, the Yahoo mobile app in both Android and iOS has no built-in settings that can alter the size of text. Moreover, even the pinch-in pinch-out gesture does not work.

So does this mean that we are stuck with the default size?

No, there is a way to change font size in Yahoo Mail even on mobile, but there is a catch.

You need to use the system settings to adjust the font size across your whole device. For many people, this might not be the best practice.

Changing the size of the text on your entire phone just so you can see the emails a little bit better is a trade-off that most people will flat out reject. If you are among them, I suggest you use your phone’s browser to access Yahoo Mail. There, the pinch-in pinch-out gesture works so you can enlarge the messages to see the text more clearly.

For the rest who are willing to change their phone’s settings, the steps are as follows.

For Android, there is no option to make font size changes at the application level; it is either all or nothing. So doing this will not only affect Yahoo Mail but also other apps on your device.

Go to Settings > Display > Font size (or a similar path) and use the slider to adjust the text size.

For iOS, you can adjust settings for just the Yahoo app; other app font sizes remain unaffected.

Like Android, here too you can set a global font size, but a better answer for how to change font size in Yahoo Mail app would be to set a font size for the particular app.

Step 1. Go to Settings > Accessibility > Per-App Settings.

Step 2. Tap Add App and select Yahoo Mail.

Step 3. Tap on Yahoo Mail in the list, choose Larger Text, and set a custom font size that only applies to Yahoo.

Best Practices Before, During, and After Adjusting Yahoo Mail Views

Before changing the view, make sure that you understand the limitations of the platform(browser/mobile) and the type of Yahoo Mail (New/classic) you are using.

Make sure you fully understand the consequences of adjusting the view. Although it is a reversible process, it is advised that you only attempt it when you feel the need for it.

Don’t alter browser settings for a shared browser profile. Also, when you compose a new email with a non-default size, you are sending instructions for the recipient’s email client to display it that way (they may choose to ignore/overwrite your instructions with their formatting rules).

Add your Yahoo Mail ID to email clients and use more advanced viewing settings.

Moreover, as we already know that the Yahoo Mail storage limits were updated recently. So use this opportunity to safeguard your Yahoo mail with the help of the SysTools Yahoo Mail backup tool.

Doing this will ensure that your emails are not only good to look at but also safe from external threats.

Conclusion

Now, anyone who wants to look at their Yahoo mail in a different font size than the default can do so easily. This tutorial covered quick adjustments for a single email, a default setting for all outgoing messages, and a powerful browser rule to make everything larger.

Not only that, but we also showcased what options are there for the Yahoo mobile app users.

So by understanding the difference between in-app, browser, and system-level settings, you can experiment and find the configuration that works best for you.
