Adding subtitles to videos can definitely improve a video-watching experience. Anyone who creates online videos, such as teachers or content marketers, should make sure to always add subtitles to video to enhance the user experience.

Numerous sources have found that a significant majority of Facebook users watch videos without the sound. Unless you add subtitles to video, it could ruin the viewer’s experience, drive away traffic, and reduce engagement.

Why Your Videos Need Subtitles

Video is everywhere online these days, which means your videos have to compete with a lot of others for attention. Subtitles are a great way to grab the eyes of someone scrolling through their social-media feed or a web page. Not only that, but adding quality subtitles to your video can keep your messaging clear and consistent.

By adding subtitles to video, you will:

  • Accurately convey your organization’s message
  • Make content accessible to hard-of-hearing or non-English speakers
  • Demonstrate your commitment to quality
  • Improve the user experience

The best subtitles to add to your video are:

  • Legible, using a sans-serif font with a consistent width and thick outlines
  • Readable, appearing on-screen long enough for the viewer to follow easily
  • Produced in a font that supports the use of symbols, such as music notes, that can provide additional information
  • Timed to follow the pacing of spoken words as closely as possible
  • Similar in style to the spoken word, even if the subtitles have to be abridged
  • Created to appear in about two lines of about 35 characters

Important Reasons for Adding Subtitles to Videos

Video Accessibility

About 466 million people, or more than 5 percent of the world’s population, has disabling hearing loss, according to the World Health Organization. By 2050, this number could grow to 25 percent, or more than 900 million people. When the subtitles you add to your videos are accurate, you ensure that deaf or hard-of-hearing consumers can also access your video content.

Quality videos send the message that your company has high standards and values your audience.

Adding subtitles to the video also may improve accessibility for non-English speakers. Those who do not speak English fluently may find it easier to understand the video’s content if there are subtitles they can follow. Another option is to provide translations for English subtitles. The improved accessibility from adding subtitles to your video can also improve your reputation and brand awareness, as more consumers can consume your content and recognize your brand as one that values inclusivity and accessibility.


Users who need or prefer subtitles may come across your video and start watching it, only to give up after seeing the subtitles are low-quality or nonexistent. This reduces the user’s chance of engaging with the video, such as leaving a comment or sharing it with others. Research from video marketing company Wyzowl shows that 83 percent of consumers would consider sharing a branded video they enjoyed. Add subtitles to help them enjoy a video, encouraging them to share it with friends.

Add quality subtitles to your video to engage viewers who might not have watched the video otherwise.

If your video is able to play automatically, such as in a Facebook feed, then the right subtitles can help capture the attention of viewers as they scroll past. Add quality subtitles to your video to engage viewers who might not have watched the video otherwise.

If your videos aren’t providing the best experience possible for viewers, you’re missing out on a chance to increase your profits.
