How often do you use subtitles for your videos and how good are they?

Subtitles are a must-have for any video content. They make your videos accessible to a wider audience, including non-native speakers and people with hearing impairments. But not all subtitles are created equal. Poorly formatted subtitles can ruin the viewer's experience.

So, let's dive into some best practices for creating clear, effective, and professional subtitles for YouTube

Understanding Subtitles: Long-Form vs. Short-Form

Long-Form Subtitles

Long-form subtitles are used in movies, TV shows, and long videos. They usually include complete sentences and cover the entire dialogue. These subtitles are smaller in font size and often appear as longer sentences to match the extended content.

Short-Form Subtitles

Short-form subtitles are common in social media videos like Instagram Reels, TikTok, and YouTube Shorts. These subtitles are larger in font size and have shorter text clusters, making them perfect for quick, engaging content. 

Key Elements of Effective Subtitles

Text Size and Color

Subtitles need to be readable. Text that’s too large can cover up the video, while text that’s too small can be hard to read. A simple sans-serif font usually works best.

Best choices:

  • White text on a black background for high contrast.
  • Black text on a white background for darker visuals.

Font Selection

Choosing the best fonts for YouTube subtitles is important for readability and setting the right tone.

  • License

Ensure the font is available for commercial use if your video has ads.

  • Availability

Choose fonts that are easily accessible in popular editing tools.

  • Weight

Medium to bold weight is recommended for clarity.

  • Aesthetic

Match the font style to your video's tone (formal for academic, casual for lifestyle content).

Placement of Subtitles

They are usually at the bottom of the screen, but placing them in the middle in short-form content can help with visibility. Avoid placing subtitles where they might block important visuals.

Synchronization and Timing

Subtitles for video need to sync perfectly with the spoken dialogue.

  • Timing

Subtitles should stay on screen long enough to read, generally around 21 characters per second.

  • Line Length

Aim for about 42 characters per line.

  • Number of Lines

Keep it to two lines max for readability.

Line Breaks and Word Clustering

Ensure that line breaks occur at natural linguistic breaks, such as at the end of clauses or sentences. Avoid splitting important phrases or names across lines.

Punctuation and Grammar

Proper punctuation and grammar make subtitles easier to read and understand.

  • Periods

Use at the end of sentences to signal completion.

  • Question marks and exclamation points

Place immediately after the last character.

  • Ellipses

Use for significant pauses within a subtitle.

Eliminating Non-Essential Sounds

Skip filler sounds like "um" and "uh" to keep subtitles clean and smooth.

Adding Emojis

Emojis can add expressiveness in short-form content but should be used sparingly to avoid overwhelming viewers.

Advanced Formatting Techniques

  • Using Multiple Fonts

Different fonts can highlight different speakers or emphasize parts of the dialogue. Just ensure it's consistent and not distracting.

  • Color and Size Contrast

Use different colors and sizes to differentiate speakers or highlight important dialogue. Ensure all text remains legible.

  • Animating Subtitles

Subtle animations, like highlighting words as spoken, can enhance engagement in fast-paced or short-form content. Use sparingly to avoid overwhelming viewers.

Final Checks Before Publishing

Review and Adjust

Before you finish your video, review it to ensure it's in sync and the subtitles are readable and formatted correctly.

YouTube subtitle rules:

  • Synchronization

Ensure subtitles match the audio timing.

  • Visibility duration

Confirm subtitles stay on screen long enough to be read easily.

  • Line breaks and length

Check for consistent line breaks and appropriate length.

Test with an Audience

Conduct a test screening with a small audience to gather feedback on subtitle readability and effectiveness. Adjust based on their input to ensure the best viewer experience.

Crafting effective subtitles for YouTube videos is all about balancing readability, timing, and aesthetics.
