How to Bold Text on iPhone 15: A Step-by-Step Guide

Want to make your text stand out in a message or document on your iPhone 15? Bold text can make a big difference. It’s pretty simple to do, and I’ll show you how in just a few steps.

Step by Step Tutorial: How to Bold Text on iPhone 15

Before we dive into the steps, it’s important to note that bolding text can help emphasize important points or make your messages look more professional. Here’s how you can do it:

Step 1: Select the Text You Want to Bold

Tap and hold the text you want to make bold until the selection tool appears.

Selecting text on an iPhone can sometimes be tricky, especially if you’re trying to select a small portion of text. Using the magnifying glass feature can help you pinpoint the exact text you want to modify.

Step 2: Tap the “BIU” Button

Once the text is selected, tap the “BIU” button in the pop-up menu.

The “BIU” button stands for Bold, Italic, and Underline. This is your go-to for any basic text formatting on the iPhone. Remember, it may look slightly different depending on the app you’re using.

Step 3: Choose “Bold”

From the options that appear, tap “Bold” to apply the bold formatting to your selected text.

After you select “Bold,” the text will immediately change to the bold font. You can select “BIU” again if you want to undo the bold formatting or add additional formatting like italics or underline.

After completing these steps, the selected text will be displayed in bold. This will make it stand out from the rest of the text, whether you’re typing an email, a note, or a text message.

Tips for Bold Text on iPhone 15

  • If you’re using the Mail app, you can also make your text bold by shaking your iPhone and tapping “Undo Typing” to reveal the formatting options.
  • In some apps, you may need to tap “Aa” instead of “BIU” to access text formatting options.
  • If you’re using a third-party keyboard, the steps to bold text may differ.
  • Remember that not all apps support text formatting. If you don’t see the BIU option, it may not be available in that app.
  • When sending a bolded text message, make sure the recipient’s device supports bold text to ensure they see the formatting.
