ACCESSIBLE DOCUMENTS | Make Your Digital Files Easier for More People to Read and Use

A document can contain valuable information and still

be difficult for people to use.

A student may receive lecture notes that cannot be navigated easily with a screen reader. A customer may struggle to read a low-contrast invoice on a phone. An employee may open a PDF only to discover that its pages are scanned images rather than searchable text. A person using assistive technology may find a long report confusing because its headings are only large, bold paragraphs instead of proper document headings.

These are document accessibility problems.

Accessible documents are designed and structured so that more people can find, understand, navigate, and use their contents. This includes people with visual, hearing, motor, cognitive, and other disabilities, as well as people working on small screens, using magnification, or dealing with temporary limitations.

You do not need to be a specialist to start improving your documents. By following a repeatable checklist, you can make reports, assignments, business proposals, CVs, manuals, invoices, presentations, and PDFs easier to use.

This guide explains how to create a more accessible document, check it before sharing, and avoid common mistakes.

1. Understand What Makes a Document Accessible

Document accessibility is not simply about making text large or choosing attractive colours. It involves how information is presented, organised, labelled, and interpreted by different people and technologies.

A useful document should have:

• Clear structure: Readers can understand how the content is organised and move between sections.
• Readable text: Font choices, spacing, contrast, and layout support comfortable reading.
• Meaningful alternatives: Important information conveyed by images is also available in text.
• Understandable links: Readers can tell what a link does or where it leads.
• Accessible tables: Data has a logical structure rather than relying only on visual position.
• Usable navigation: People can move through the document using headings, a keyboard, or assistive technology.
• Reliable content: The document retains useful structure when shared, downloaded, or exported to another format.

Accessibility also depends on the document's purpose. A decorative image in a birthday invitation does not need the same treatment as a diagram explaining a technical process. A simple list of prices does not need the same structure as a complex financial table.

The goal is to make the information usable—not merely to make a document look polished.

2. Start With a Clear Document Structure

One of the most useful improvements is to organise a document with real headings.

Imagine creating a report with the following sections:

• Introduction
• Project Objectives
• Budget
• Timeline
• Recommendations

You might make each heading bold and increase its font size. Visually, the report could look well organised. But if each heading is formatted only as ordinary text, some assistive technologies may not recognise the document's structure.

Instead, use the heading styles provided by your document editor.

How to do it

1. Write the document title at the beginning.
2. Apply the document title style where your editor provides one.
3. Use a main heading style for major sections.
4. Use a lower-level heading for subsections.
5. Keep heading levels logical. For example, use Heading 2 for a major section and Heading 3 for a subsection within it.
6. Use the document's navigation or outline view to check whether the sections appear in a sensible order.

Avoid selecting heading styles only because they produce a particular font size. Choose the correct structural level, then adjust the appearance if necessary.

Why this matters: Headings help readers scan long documents and allow people using screen readers or keyboard navigation to move directly between sections.

3. Make Text Comfortable to Read

Text that looks attractive on one screen may be difficult to read on another.

Consider the reader who opens your report on a small phone, enlarges the text, or uses a high-contrast display. A layout that depends on tiny lettering, pale colours, or tightly packed paragraphs can quickly become frustrating.

Use these practices:

• Choose a readable font and a comfortable text size.
• Use sufficient spacing between paragraphs and sections.
• Break long passages into meaningful paragraphs.
• Use lists for related items instead of creating one enormous sentence.
• Avoid decorative fonts for long passages.
• Use strong contrast between text and its background.
• Do not communicate essential information through colour alone.

For example, do not identify overdue invoices only by colouring them red. Include a clear label such as Overdue so the meaning is not dependent on colour perception.

For WCAG 2.2 Level AA, the general minimum contrast ratio is 4.5:1 for normal text and 3:1 for large text, subject to the standard's definitions and exceptions. These ratios are useful technical checks, but they do not replace reviewing how the content looks in its real layout.

4. Give Important Images Meaningful Text Alternatives

Images can explain ideas more quickly than paragraphs, but an image may not communicate its information to someone who cannot see it.

Alternative text—often called alt text—provides a text equivalent for an image when that image conveys information the reader needs.

Suppose your document contains a diagram showing how a customer places an order, pays, and receives a product.

A weak description would be:

image1

A more useful alternative might be:

Diagram showing a customer placing an order, completing payment, and receiving the product.

The description should communicate the image's relevant purpose or information, not simply announce that an image exists.

How to improve image accessibility

1. Identify images that communicate information.
2. Determine what a reader needs to understand from each image.
3. Add concise, meaningful alternative text using the image's accessibility or alt-text settings.
4. Check that the description matches the image and its context.
5. Avoid repeating the entire surrounding paragraph unnecessarily.

Decorative images that contribute no useful information should generally be marked or implemented so that assistive technologies can ignore them.

If a chart contains important figures or relationships, consider providing a short explanation or accessible data table as well. A brief alt-text description may not communicate every detail of a complicated chart.

5. Use Descriptive Links

Links are easier to use when their labels communicate their purpose.

Compare these examples:

Less informative: Click here.

More informative: Read the official guide to accessible documents.

The second label gives the reader a clearer idea of what will happen.

When preparing a document:

1. Select the text that should act as a link.
2. Add the destination address.
3. Make the link text describe the destination or action.
4. Check that the link opens the intended resource.
5. Avoid leaving important web addresses broken across lines where they become difficult to identify or copy.

A short label can still be appropriate when its purpose is obvious from context. The important point is that the reader should not have to guess what a link means.

For important references, use reliable sources and check the destinations before distributing the document.

6. Build Tables That Communicate Their Meaning

Tables are useful for budgets, timetables, inventories, comparison reports, and other structured information. However, a table that looks clear visually may be confusing when read with assistive technology.

Consider a budget table containing item names, quantities, unit prices, and totals.

Make sure:

• Each column has a meaningful heading.
• Rows and columns follow a consistent structure.
• The table is used for data rather than merely arranging decorative page elements.
• The information remains understandable when read in sequence.
• Essential information is not communicated through colour alone.
• The table does not depend on complicated merged cells when a simpler structure would work.

For a long or complex table, consider whether it should be split into smaller tables with clear headings.

After creating the table, inspect it at a smaller screen size. If the columns become unreadable or the reader must scroll sideways excessively, consider simplifying the layout or providing a more suitable alternative.

7. Choose the Right Document Format

The format you share affects how people can access the content.

Editable documents

Formats such as DOCX and Google Docs are useful when recipients need to edit, comment on, or collaborate on the content. Their accessibility depends partly on how you structure the document and on the software used to open it.

PDF files

PDFs are useful when you want to preserve a document's appearance across devices. However, a PDF is not automatically accessible just because it looks correct.

A PDF may contain selectable text and a useful reading structure, or it may consist of scanned page images with little accessible text.

When preparing a PDF:

1. Start with a well-structured source document.
2. Use the application's appropriate export or download function.
3. Avoid treating a screenshot or scan as an equivalent substitute for structured text.
4. Check whether text can be selected and searched.
5. Review the PDF's reading order, headings, links, and image alternatives where applicable.
6. Test the resulting file rather than assuming the export preserved every accessibility feature.

If you must share a scanned document, consider whether OCR (optical character recognition) can create searchable text. OCR results can contain errors, so review the recognised content. Complex PDFs may need additional tagging and remediation before they are accessible.

8. Use the Accessibility Features in Your Editor

Many document editors provide features that help you identify or reduce accessibility problems.

In Microsoft Word

Microsoft documents an Accessibility Checker that can help you identify issues while creating or reviewing a document. It also provides guidance on alternative text, headings, colour, and other accessibility practices.

A practical workflow is:

1. Open your document in Word.
2. Review the document structure and image descriptions.
3. Run the Accessibility Checker using the options available in your version of Word.
4. Read each finding and decide what action is appropriate.
5. Make corrections where needed.
6. Run the check again before sharing the document.

The exact interface can differ by Word version and device, so consult Microsoft's current instructions for your version.

In Google Docs

Google provides guidance for making documents and other Workspace files more accessible, including adding alt text, using headings, and supporting screen-reader use.

When preparing a Google Doc:

1. Apply the built-in heading styles.
2. Add useful alternative text to informative images.
3. Use lists and tables thoughtfully.
4. Review the document's link text and visual readability.
5. Consult Google's accessibility guidance for the editor and assistive technology you use.
6. If you download or export the document, inspect the exported file as well.

An editor's accessibility features are useful aids, but they cannot make every decision for you. A tool may identify a missing alt-text field, for example, without knowing whether the description you write is accurate or helpful.

9. Test the Document Before Sending It

Do not wait until someone reports a problem to discover that your document is difficult to use.

Before sending a report, assignment, invoice, proposal, or other important file, perform a short review.

The practical review

Structure

• Does the document have a clear title?
• Are headings applied in a logical hierarchy?
• Can you understand the sections from the navigation or outline view?

Text and appearance

• Is the text readable?
• Is there enough contrast?
• Does the layout remain usable when zoomed in?

Images and links

• Do important images have meaningful alternatives?
• Are decorative images handled appropriately?
• Do links describe their purpose and open the correct destinations?

Tables and lists

• Are data tables organised clearly?
• Are lists formatted as actual lists where possible?
• Can the information be understood without relying on visual position alone?

Exported files

• Does the downloaded or exported file open correctly?
• Can you select or search its text where appropriate?
• Is the reading order sensible?
• Have important headings, links, and image alternatives been retained?

Where possible, also test with a screen reader or ask people who use assistive technology to review the document. Real user feedback can reveal problems that automated checks miss.

10. Common Mistakes to Avoid

Mistake 1: Making every heading bold instead of using heading styles

Why it matters: Visual formatting alone may not communicate the document's structure to assistive technology.

Better approach: Apply the appropriate heading styles and then customise their appearance if necessary.

Mistake 2: Writing meaningless alt text

Why it matters: A description such as “picture” may tell the reader almost nothing about an informative diagram.

Better approach: Describe the relevant information or function of the image.

Mistake 3: Assuming every PDF is accessible

Why it matters: A visually correct PDF may have missing structure, an incorrect reading order, or scanned text that cannot be selected.

Better approach: Inspect the exported PDF and address its specific problems.

Mistake 4: Treating an automated check as a final verdict

Why it matters: Automated tools cannot judge every aspect of meaning, usability, and assistive-technology interaction.

Better approach: Combine automated checks with manual review and, where possible, feedback from people with disabilities.

Mistake 5: Waiting until the document is finished

Why it matters: Adding structure, correcting tables, and fixing image descriptions can be harder after a document has grown complicated.

Better approach: Build accessibility into the document as you write.

11. Your 10-Minute Accessibility Exercise

Choose a document you already use—a CV, school assignment, business proposal, report, or set of notes.

Spend ten minutes reviewing it:

1. Identify its title and major sections.
2. Apply proper heading styles where needed.
3. Check the readability of the text and contrast of the colours.
4. Inspect the images and add meaningful alternative text where appropriate.
5. Replace vague link labels with clearer descriptions.
6. Review any tables for logical structure.
7. Run the available accessibility checker, if your editor provides one.
8. Save a copy and inspect the exported file if you share it as a PDF.

Write down three improvements you made and one issue that still needs attention.

The aim is not to achieve a perfect document in ten minutes. It is to develop a repeatable habit that makes your digital content more usable.

12. Official Resources for Further Learning

Use these sources when you need more detailed guidance:

• Google: Make your documents, presentations, sheets, and videos more accessible
• Microsoft: Make your Word documents accessible to people with disabilities
• W3C: Guidance on applying WCAG to non-web documents and software
• W3C: Web Content Accessibility Guidelines (WCAG) 2.2

Requirements and available features can differ between applications, versions, and document formats. Use the guidance relevant to the software and file you are preparing.

Final Thoughts

An accessible document does more than look organised. It helps people locate information, understand its structure, follow links, interpret images, and use the content with different devices and assistive technologies.

You can begin with a few practical habits: use proper headings, write meaningful image descriptions, choose clear link labels, structure tables carefully, check readability, and inspect files after exporting them.

These improvements can benefit students, teachers, employees, customers, business owners, and anyone who shares digital information.

Make accessibility part of how you create—not just a check you perform before sharing.
