Quick answer

For most social video captions, start with a bold sans-serif font, high contrast, and an outline or background that separates text from the footage. Keep lines short, test the video at phone size, avoid thin weights, and position captions away from platform controls and important visuals.

Start with a bold, simple typeface

Sans-serif faces with open letterforms remain readable at small sizes and over compression. Display or handwritten fonts can work for emphasis, but should be tested with every character the transcript uses.

Size captions for a phone, not an editor window

Preview the full 9:16 frame at approximately phone size. If a caption only looks comfortable on a desktop canvas, it is probably too small for the feed.

Contrast must survive every frame

White text with a dark outline or translucent dark background is a dependable baseline. Bright accent colors work best as selective highlights rather than the only legibility mechanism.

Short lines reduce eye travel

A compact phrase is easier to read without looking away from the subject. Keep conventional subtitles to no more than two lines and use even shorter chunks for animated short-form styles.

Animation and accessibility are different goals

Fast word animation can support energetic creator content, but it can also distract or become hard to follow. Use a calmer style when comprehension and accessibility are the primary goals.

Step by step

From source video to captioned MP4.

  1. 1

    Choose a readable preset

    Start with a bold style appropriate to the tone of the clip.

  2. 2

    Preview at phone size

    Judge readability on the complete frame instead of a zoomed editing canvas.

  3. 3

    Check bright and busy shots

    Scrub through the video and strengthen the outline or background where needed.

  4. 4

    Confirm the safe position

    Keep text away from faces, controls, and platform interface areas.

Common questions

Frequently asked questions.

What is the best font for video captions?

A bold, clean sans-serif is the safest general choice because it stays legible at small sizes. The best specific font still depends on the language, footage, brand, and desired tone.

Should captions have an outline or background?

Usually yes. An outline, shadow, or contrasting background prevents text from disappearing when the footage becomes similarly colored or visually busy.

How many lines should a caption use?

Use no more than two lines for conventional captions. Animated short-form captions often use a much shorter phrase or only a few words at a time.

Are animated captions always more readable?

No. Animation can guide attention, but excessive motion can distract. Choose motion based on the audience and purpose rather than applying it to every video.
