How to check TikTok caption readability.

Read captions at normal viewing size.

Do not judge on-screen text only from an editing timeline or large monitor. Watch the exported draft on a phone and check whether the words can be understood quickly while the video is moving.

Keep each moment easy to scan.

• Use enough contrast between text and the footage behind it.
• Break long thoughts into short, readable lines.
• Give viewers enough time to read before the next caption appears.
• Avoid placing essential text where it competes with a face, product, or action.

Check placement across the whole draft.

A caption may look fine in one scene and disappear into a bright, busy, or fast-moving shot in the next. Review every caption moment, especially when the background changes.

Make the smallest useful edit.

When a caption is difficult to follow, change one thing first: simplify the wording, increase contrast, move it, or give it more time. Then replay that moment in context.
