How to Change Text Size in TikTok in 2025 (Easy)

In this guide, we’ll walk you through the easy steps to adjust the text size on TikTok, allowing you to personalize your experience on the platform.

TikTok is one of the most popular social media platforms for short videos — but it can also be a great place for messaging with friends and followers. However, have you ever found the default text size difficult to use or read messages while chatting in the app? 

We’ll show you how easy it is to adjust and customize the font size in TikTok’s messaging feature in just a few simple steps. 

TikTok offers text size options to increase accessibility, unlike some other messaging apps. So whether you want larger text for easier reading or a more space-efficient compact text size, personalizing your TikTok chats is possible. Follow along as we outline the quick process for changing font sizes in TikTok to match your needs and preferences.

How to Change Text Size in TikTok (Easy)

Before we head over to the steps, you need to know that there are two ways to change the size of text in TikTok. First, you can adjust the overall app font. This controls the text size for comments, captions, usernames, messages, and buttons. Make it bigger if you’re having trouble reading or smaller if you want more space for videos.

Second, you can resize text overlays. These are the words and phrases you add directly onto your videos when editing. This text lets you get creative with visuals and captions. Whether you prefer subtle, small text or big, eye-catching words, TikTok lets you adjust the size.

In this guide, we’ll explain the easy ways to adjust text size on TikTok for both your TikTok font and your text overlays.

Other Ways to Adjust Text Size on TikTok

No need to worry if you can’t locate the Accessibility settings within TikTok to adjust text size. You have another option – you can change the system-wide text size in your device’s Settings app instead.

On Android

1. Locate and open the Settings on your Android. Tap the gear icon to access Settings.
2. Scroll down and tap “Display“.
3. Select “Text Size” from the Display settings options. Tap it to open text resize options.
4. Use your finger to slide the size slider to the desired size. Drag right to enlarge the text or left to shrink it.
5. Once you find an ideal text size, tap the Back arrow icon in the upper left. This will save the changes.

Note: Keep in mind that various smartphone brands might use different names for options on their customized Android OS. Consequently, the steps could vary. If you’re having trouble finding the specific setting, try searching for “Font Size” or “Text Size” in your device’s settings to locate the option for changing the font.

On iOS

1. Open up the Settings app on your iPhone. 
2. Scroll down and select “Display & Brightness” by tapping on it. This option controls various display settings.
3. Next, choose “Text Size” from the available settings. Tap on it to open text sizing.
4. Once the Text Size menu opens, slide your finger across the slider to adjust and enlarge the text. Push the slider to the right to increase the font size to make it bigger. Slide it left to shrink the text down smaller.
5. When you have found a comfortable reading size, tap on the small Back arrow found in the top left corner of your screen. Tapping Back will save your changes.

Keep in Mind: Altering text size this way affects all aspects system-wide, not just for the TikTok app.
