Accessible Content for Creators: A Composite Guide to What the Standards Say

Accessibility makes content usable for more people, including people with visual, hearing, motor and cognitive disabilities. It also tends to make content better for everyone: captions help people watching without sound, clear structure helps skimmers and good contrast helps everyone on a sunny day.

This composite guide summarises what accessibility standards and guidance broadly recommend for creators. It contains no invented quotes. Primary sources include the W3C's Web Content Accessibility Guidelines (WCAG), platform help centres and guidance from disability organisations. For blog-specific steps, see our blog accessibility checklist.

The WCAG principles

WCAG is organised around four principles, often summarised as POUR:

1. Perceivable: information must be presented in ways people can perceive (for example, text alternatives for images, captions for video).
2. Operable: interfaces must be usable (for example, keyboard accessible, no content that causes seizures).
3. Understandable: content and interfaces must be understandable (for example, readable text, predictable navigation).
4. Robust: content must work with assistive technologies.

WCAG 2.2 was published as a W3C Recommendation in 2023.

Captions

• Add captions to all videos with speech.
• Review automatic captions; they make mistakes, especially with names and jargon.
• Include important sounds, not just speech.
• Make sure on-screen text does not overlap captions.

See our guide to captioning and transcription tools.

Transcripts

Podcasts and audio-only content need transcripts. Transcripts also help video viewers who prefer reading, and can help search engines understand content.

Alt text

• Describe images meaningfully on websites and on platforms that support alt text, including Instagram, X, Pinterest and many others.
• Focus on what matters in context.
• Keep it concise.
• Decorative images can have empty alt text on websites.

Colour and contrast

• WCAG recommends a contrast ratio of at least 4.5:1 for normal text (Level AA).
• Do not rely on colour alone to convey information.
• Test graphics and text overlays for contrast.

Text in images

Text embedded in images cannot be read by screen readers unless it is also provided as text. Include the important text in captions or alt text.

Motion and flashing

• WCAG advises against content that flashes more than three times per second.
• Provide warnings for flashing content.
• Avoid unnecessary auto-playing animations on websites, or provide a way to pause them.

Hashtags and emoji

• Capitalise each word in multi-word hashtags (#CreatorTips rather than #creatortips) so screen readers can pronounce them correctly; this practice is widely recommended by disability advocates.
• Use emoji sparingly; screen readers read their descriptions aloud, which can be long and disruptive.
• Avoid using special "fancy" Unicode fonts in captions or bios, because screen readers may read them as strings of symbol names or skip them.

Plain language

• Use short sentences and common words.
• Explain jargon.
• Use headings and lists to structure content.

Audio description

For videos where important information is visual only, consider describing it in the narration or providing audio description.

Inclusive representation

Accessibility includes representation. Including disabled people in content, with their consent and in respectful ways, and following guidance from disability organisations on language, helps make content more inclusive.

Testing

• Use your phone's screen reader (VoiceOver on iOS, TalkBack on Android) to test your content.
• Use contrast checkers.
• Ask for feedback from your audience.

Legal context

In many countries, accessibility laws apply to organisations, and the European Accessibility Act applies to certain products and services from 2025. Individual creators may not be directly covered, but brands you work with may require accessible content.

The summary

Caption videos, transcribe audio, write alt text, ensure contrast, avoid flashing content, use accessible hashtags and plain language, and test with real assistive technology. These steps make your content usable for more people and better for everyone.

Worked examples

Alt text for an outfit photo. Weak: "photo of me". Better: "Woman in a camel wool coat, white trainers and wide-leg jeans standing on a city pavement." The better version describes what someone would miss if they could not see the image, in context.

Alt text for a chart. Summarise the point rather than every number: "Bar chart showing newsletter sign-ups rising from 40 in January to 160 in June." Put the full data in a table or the text if it matters.

Captions for a tutorial. Automatic captions might render a product name incorrectly; correct every brand and technical term. Add sound descriptions where relevant, such as "[timer beeps]".

An accessible hashtag. #SustainableFashionTips rather than #sustainablefashiontips.

A quick audit you can run in 30 minutes

1. Pick your three most recent posts or videos.
2. Check that each video has accurate captions.
3. Check that each image has meaningful alt text.
4. Run your brand colours through a contrast checker.
5. Turn on your phone's screen reader and listen to one post or caption, including emoji and hashtags.
6. Note every problem and fix the template or habit that caused it, not just the instance.

Contrast ratios in practice

WCAG 2.x defines contrast ratios from 1:1 (no contrast) to 21:1 (black on white). Level AA requires 4.5:1 for normal text and 3:1 for large text, which WCAG defines as at least 18 point, or 14 point bold. Level AAA raises those to 7:1 and 4.5:1. For text overlaid on photos, contrast changes across the image, so add a solid or semi-transparent background behind the text.

Why it matters at scale

The World Health Organization estimates that at least 2.2 billion people worldwide have a near or distance vision impairment. It also estimates that over 1.5 billion people live with some degree of hearing loss. Accessible content is not a niche concern; it reaches a very large audience.

Frequently asked questions

Do I need to caption short clips? Yes, if they contain speech. Many viewers watch short-form video with the sound off.

Is automatic alt text good enough? Automatically generated descriptions are improving but often miss context. Review and replace them with your own.

Do accessibility tools or overlays make a website compliant? Accessibility overlay widgets have been criticised by many disability advocates and accessibility professionals. They do not replace accessible design and content.

Where can I learn more? The W3C Web Accessibility Initiative publishes free tutorials and an introduction to WCAG. Platform help centres explain how to add captions and alt text.
