Creating Accessible Digital Content

Use this page to create and check accessible documents, presentations, PDFs, images, video, social media, and other digital content. Start with the checklist below, then choose the type of content you are creating for more specific guidance.

Before you publish or share content:

Use this checklist with all digital content:

  • Use readable fonts and sizes appropriate to the format. As a starting point, use 12-point or larger body text in documents and 24-point or larger body text in presentations. Do not shrink text simply to make additional content fit.
  • Use headings, lists, tables, and other built-in structure correctly.
  • Make sure the content follows a logical reading order.
  • Write descriptive link text instead of using “click here” or displaying long web addresses.
  • Add appropriate text alternatives to meaningful images and mark decorative images as decorative.
  • Check color contrast and do not use color alone to communicate meaning.
  • Provide accurate captions for video and transcripts for audio. Describe important visual information that is not communicated through the audio.
  • Run the accessibility checker built into the application you are using.
  • Complete a manual review and check the final version after it is exported, uploaded, or published.

Accessibility checkers can help identify potential barriers, but checker results alone do not determine whether content is accessible. Combine automated checks with checklists, manual review and, when appropriate, testing by people who use assistive technology.

About these recommendations: The font, size, and spacing recommendations below are practical NCDPI starting points intended to support consistent, readable content. They do not replace the need to check structure, color contrast, reading order, resizing, and the final published format.

Accessibility Essentials for all content:

What to do:

  • Determine what the image contributes in its current context.
  • Add concise alternative text to meaningful images. Describe the image’s purpose or essential information rather than every visible detail.
  • Mark an image as decorative when it adds no information and performs no function. In HTML, decorative images generally use an empty text alternative: alt="".
  • When an image contains essential text, provide that information as real text nearby whenever possible.
  • For charts, diagrams, maps, infographics, and other complex visuals, provide a short alternative text and make the complete information available in nearby text, a list, or an accessible data table.
  • For an image used as a link or button, describe the action or destination rather than its appearance.
  • Review automatically generated alternative text before publishing. Do not assume an AI-generated description reflects the image’s purpose.

How to check:

  • Read the alternative text without looking at the image. Confirm that it communicates the reason the image is included.
  • Look for filenames, automatically generated wording, and descriptions beginning unnecessarily with “image of” or “picture of.”
  • Confirm that nearby text and the alternative text do not unnecessarily repeat each other.
  • Confirm that decorative images will be ignored by assistive technology.
  • Confirm that detailed information from complex visuals is available outside the alternative-text field.
  • For linked images, confirm that the text alternative identifies what will happen when the link is activated.

What to do:

  • Use a contrast ratio of at least 4.5:1 for most text.
  • A ratio of 3:1 may be used for text that is at least 18-point regular or 14-point bold.
  • When there is uncertainty about whether text qualifies as large, use the 4.5:1 ratio.
  • Use at least 3:1 contrast for meaningful icons, graphical objects, and visible boundaries of interactive controls.
  • Do not use color alone to identify required information, errors, status, categories, or instructions.
  • Use text, labels, patterns, shapes, or icons in addition to color.
  • Avoid placing text over busy images, gradients, or changing backgrounds unless contrast remains sufficient.
  • Establish approved color combinations for recurring templates and brand materials.

How to check:

  • Test foreground and background colors with a contrast-checking tool.
  • Check ordinary text, large text, links, icons, charts, and form controls separately.
  • Review the content in grayscale to identify information communicated only through color.
  • Check hover, focus, selected, disabled, and error states when reviewing interactive content.
  • Confirm that text placed over an image remains readable across the entire text area.
  • Record approved color combinations so staff do not have to test the same combinations repeatedly.
Learn more:

What to do:

  • Use built-in heading styles to identify the title, major sections, and subsections.
  • Choose heading levels based on the relationship between sections, not on the visual appearance of the style.
  • Keep headings concise, descriptive, and meaningful when read on their own.
  • Use the same heading level for sections that have the same organizational importance.
  • Use a lower-level heading for content that belongs within a section.
  • Do not use large, bold, colored, or centered paragraph text as a substitute for a heading style.
  • Do not insert empty headings to create visual space.
  • Use built-in numbered lists, bulleted lists, and table tools rather than typed symbols, tabs, or spaces.
  • Use paragraph spacing and styles rather than repeated blank lines to create separation.

How to check:

  • Open the Navigation Pane, document outline, or heading list.
  • Read only the headings and confirm that they form a meaningful outline of the content.
  • Look for visual section titles that do not appear in the outline.
  • Look for empty headings or headings used only to change the appearance of text.
  • Confirm that numbered and bulleted items use real list formatting.
  • Confirm that table content is inside a real table rather than aligned with tabs or spaces.
  • In webpages and LMS content, confirm that the visible page title and the underlying heading structure work together logically.

What to do:

  • Provide accurate, synchronized captions for prerecorded video with meaningful audio.
  • Review and correct automatically generated captions before publishing.
  • Include speaker identification and meaningful sounds when they are needed to understand the content.
  • Provide a transcript for audio-only content.
  • Provide a video transcript when it offers needed access, supports reuse, or makes complex content easier to review.
  • Communicate important visual information through the existing narration or through audio description.
  • Use a media player whose controls, captions, and settings can be operated with a keyboard and assistive technology.
  • Make sure users can pause, stop, and control media that starts or moves automatically.
  • Plan live captions and other access needs before webinars, meetings, and streamed events.
  • Provide sign-language interpretation or other communication access when required for the event or requested by a participant.

How to check:

  • Watch the video with the sound off and captions enabled.
  • Confirm that the captions are accurate, synchronized, complete, and identify speakers or important sounds when needed.
  • Listen to the video without looking at the screen and identify information that is available only visually.
  • Compare the transcript with the final published recording.
  • Operate the media player with only a keyboard.
  • Confirm that captions, transcripts, and audio-description options remain available in the final location where the media is embedded or published.
  • Test live-caption and interpretation arrangements before the event begins.
Learn more:

What to do:

  • Run the accessibility checker built into the authoring application when one is available.
  • Review and correct the issues the checker identifies. Do not use the absence of checker errors as proof that the content is accessible.
  • Complete the relevant manual checks for headings, reading order, links, images, tables, color, captions, keyboard access, and other content features.
  • Check the final version after it has been exported, uploaded, embedded, converted, or published.
  • Review webpages and interactive content using keyboard navigation and increased zoom.
  • Use assistive-technology and user testing for high-impact content, services, and workflows when appropriate.
  • Record unresolved barriers, identify who owns the correction, and determine how access will be provided while the barrier is addressed.
  • Recheck recurring templates and workflows after software, platform, or template changes.

How to check:

  1. Run the available automated checker.
  2. Complete the universal manual checklist.
  3. Review the final published or exported format.
  4. Test keyboard access, focus, zoom, resizing, and reflow where applicable.
  5. Test the most important user tasks from beginning to end.
  6. Use a screen reader or other assistive technology when the content’s risk, complexity, or use warrants it.
  7. Confirm that a person encountering a barrier has a clear way to request help or an accessible format.

  • For a linked image, make sure the text alternative communicates the destination or action.
  • Avoid URL-shortening services when they obscure the destination or reduce user trust.
  • When a visible web address is needed for printed use, provide it in addition to—not instead of—descriptive digital link text.
  • Avoid forcing links to open in a new window unless necessary. Disclose the behavior when it cannot be avoided.
  • Scan the linked text.
  • Test the links and file permissions.
Create simple, structured tables
  • Use tables only for data that has meaningful row and column relationships.
  • Identify column headers and row headers when the application supports them.
  • Avoid merged cells, split cells, nested tables, and blank spacer rows or columns.
  • Put the table title, source, units, and explanatory notes outside the data grid.

PDFs are a common format for sharing documents, but they can pose challenges for accessibility. This guide helps you decide when to use PDFs, when to avoid them, and how to make them more accessible when necessary.

  1. Decide whether PDF is the right format: Use HTML when information is primarily intended to be read online, changes frequently, or needs to adapt easily to different screens and user settings. Use PDF when a fixed-layout or downloadable document is genuinely needed and the organization can create, check, remediate, and maintain it accessibly.

  2. Create an accessible source file:

    • Apply the applicable document, presentation, or spreadsheet guidance before creating the PDF.
    • Use built-in headings, lists, and tables.
    • Add meaningful alternative text.
    • Use descriptive links and sufficient contrast.
    • Use readable text and spacing.
    • Do not create a PDF by scanning a printed document.
  3. Export using a supported process:
    • Use the authoring application’s supported Save As or Export to PDF process.
    • Avoid Print to PDF when it removes tags, links, bookmarks, or other structure.
    • Preserve document title, language, links, and bookmarks when the source application supports them.
    • Keep the source file so recurring corrections can be made before the next export.
  4. Review and remediate the resulting PDF:
    • Whether the PDF is tagged by viewing the accessibility tags.
    • Heading, paragraph, list, and table structure.
    • Logical tag order in the accessibility tags panel and reading order in the reading order and content panel.
    • Alternative text and decorative content.
    • Links and link annotations.
    • Document title and language.
    • Bookmarks in longer documents.
    • Form-field labels, tooltips, grouping, and tab order when the PDF contains a form.
    • Whether scanned pages contain accurate text and appropriate structure.
  5. Verify the final PDF:
    • Run an automated checker like the PDF Accessibility Checker or PAC or other similar tools.
    • Review the tags and reading order manually.
    • Review the PDF at increased zoom.
    • Test complex or high-impact PDFs with assistive technology when appropriate.
    • Do not describe the file as accessible solely because Adobe or PAC reports no errors.
  6. When the PDF cannot yet be made accessible: Provide the information in an accessible HTML or source-document format and clearly identify how someone can request assistance or another accessible format. An alternate format should not become a substitute for correcting a recurring inaccessible production process.

Use a consistent, predictable course organization
  • Organize modules, topics, weeks, or units consistently.
  • Use meaningful page, assignment, module, and file names.
  • Provide a clear starting point.
  • Remove outdated, duplicate, and unpublished content that users may still encounter.
  • Use current and unambiguous dates.
  • View the course as a student.
  • Confirm that the next action and navigation pattern are predictable from one module to the next.
Use native LMS pages when appropriate
  • Use the LMS rich-content editor for material that is primarily read online.
  • Apply headings, lists, links, tables, images, and media accessibly.
  • Avoid uploading a PDF or document when an accessible native page would serve the task better.
  • Review the page structure and keyboard access.
  • Test the page on a narrow screen and at increased zoom.
Structure text and visuals accessibly

  • Do not rely on color, indentation, or visual position alone.
  • Keep complex visual information available in text or data.
  • Review the heading outline.
  • Scan links and alternative text.
  • Review the page without images and color.
Check every uploaded file
  • Check Word, Google, PowerPoint, PDF, spreadsheet, and other files before uploading.
  • Use descriptive filenames.
  • Remove inaccessible duplicate versions.
  • Provide HTML or another accessible format when it better supports the task.
  • Open each file from the student view.

  • Test keyboard navigation, errors, submission, and feedback.
  • Verify accommodation settings with a test account when feasible.
Evaluate third-party and LTI tools separately
  • Review accessibility evidence before adoption.
  • Test the actual product and the specific tasks students must complete.
  • Do not treat an ACR, VPAT, vendor statement, or presence in an app marketplace as proof of accessibility.
  • Establish an alternate path when a tool creates barriers.
  • Complete critical tasks by keyboard and with appropriate assistive technology.
  • Review the tool again after major updates.
Recheck copied and imported content
  • Review content after copying a course, importing a package, changing themes, or migrating between LMS platforms.
