Web Content Accessibility Guidelines (WCAG)

Compliance with accessibility standards ensures that people with visual or hearing impairments can access your video & audio content.

Legislations, such as the Americans with Disabilities Act (ADA) and the European Accessibility Act (EAA) consider the WCAG guidelines as a best practice.

WCAG standards

What is WCAG?

Guidelines for accessible digital content, regardless of people's abilities or disabilities.

WCAG stands for Web Content Accessibility Guidelines. It is a set of guidelines and standards developed by the Web Accessibility Initiative of the World Wide Web Consortium (W3C).

The WCAG is a set of guidelines which aim to make web content more accessible to people with disabilities. Following these guidelines can help you to create a more inclusive digital environment.

WCAG accessibility guide.

For audio and video content, WCAG provide specific recommendations to ensure that the content is accessible to a wide range of users, including those with disabilities.

Captions

Provide captions for pre-recorded audio content. Captions should be synchronised with the media and include all relevant information. This is particularly important for individuals who are deaf or hard of hearing.

Audio descriptions

For video content, provide audio description of visual information that is essential for understanding the content. This benefits users who are blind or visually impaired.

Descriptive transcripts

Provide a text transcript for all pre-recorded audio content. This allows users who cannot hear the audio to access the information through text.

Sign language

For prerecorded video and audio content, provide sign language interpretation to make the information accessible to users who rely on sign language.

Adaptable content

Ensure that the media player can be operated using a keyboard, as some users may have difficulty using a mouse. This helps meet the needs of users with mobility impairments.

Keyboard access

Ensure that all functionality of the media player is operable via a keyboard interface, allowing users who cannot use a mouse to control and access the media.

Focus visible

Ensure that there is a visible focus indicator that can be seen and operated by keyboard users. This helps users with visual or motor disabilities understand where they are in the media player interface.

Accessible player controls

Provide controls for users to pause, stop, or hide any moving, blinking, scrolling, or auto-updating content within the media player. This helps users with cognitive or attention-related disabilities.

Flashing content

Content cannot have more than 3 flashes per second unless the flashing content is small enough, the flashes are low contrast, and they do not violate the general flash threshold.

Colour contrast

Small text (below 18 pt regular or 14 pt bold font) must have a minimum of 4.5 to 1 contrast ratio with the background. Large text (over 18 pt or 14 pt bold) must have at least a 3:1 contrast ratio with the background.

WCAG standards

Why WCAG?

Following WCAG guidelines is considered a best practice for meeting the accessibility requirements under the Americans with Disabilities Act (ADA), even though the ADA does not specifically mandate compliance with WCAG.

The European Accessibility Act (EAA) acknowledges and incorporates the WCAG guidelines as a recognised standard for media accessibility, emphasising the importance of making digital content accessible for people with disabilities.

4 WCAG principles.

WCAG is set around four principles: perceivable, operable, understandable, and robust. Sometimes communicated by the acronym POUR.

Perceivable: Text Alternatives

Provide text alternatives for any non-text content so that it can be changed into other forms that people need, such as large print, braille, speech, symbols, or simpler language.

Perceivable: Time-based Media

Provide alternatives for time-based media, such as audio and video. This includes providing captions for video content and text transcripts for audio content.

Operable: Keyboard Accessible

Make all functionality available from a keyboard. This is important for users who may have difficulty using a mouse, including some individuals with mobility impairments.

Operable: Enough Time

Provide users enough time to read and use content. This includes controls within media players to allow users to pause or stop, benefiting users with cognitive or attention-related disabilities.

Understandable: Readable

Make text content readable and understandable. While this guideline is broad, it can be applied to ensuring that text content associated with media is clear and easy to comprehend.

Robust: Compatible

Maximize compatibility with user agents, including assistive technologies. This involves using standard and well-supported formats for media content to ensure widespread accessibility.

Media accessibility compliance lawsuits

Lawsuits are estimated to continue to increase.

In the US large organisations have been the main target of ADA accessibility lawsuits for years, but smaller companies (under $25 million revenue) received 77% of cases in the first half of 2023 alone.

In the European Union (EU), the deadline is June 28, 2025 for companies to act and ensure compliance with the European Accessibility Act (EAA). After the deadline, we can expect to start seeing accessibility lawsuits in the EU.

How to conform with WCAG standards?

Aim for WCAG level AA. This ensures a baseline of accessibility for a wide range of users.

A
Provide text alternatives
for non-text content, such
as captions for videos and transcripts for audio.
AA
Ensure keyboard accessibility
for media players, provide audio descriptions for videos, and sufficient contrast in text.
AAA
Provide sign language for live video content and ensure that captions are positioned in a way that does not obscure important visual information.

Listening

Many people who are Deaf can read text well. They get the audio information from transcripts or captions. Some people prefer sign language.

Eye icon

Seeing

Some people who are hard of hearing like to listen to the audio to hear what they can, and have captions to fill in what they can’t hear adequately.

Brain icon

Processing

Some people who have difficulty processing auditory information also use captions. Many use transcripts so they can read at their own pace.

Speech icon

Comprehending

Some people cannot focus and comprehend auditory or visual information when there are changing visuals. For most videos, they also need descriptive transcripts.

Specific requirements vary based on regional laws and regulations. However, both the ADA in the US and EAA in the EU consider the WCAG guidelines as a best practice.
