Equitable Use

Also known as: Principle 1 of Universal Design

Simply put

Equitable Use is the first of the seven Principles of Universal Design, which call for products and environments to be usable by people with a wide range of abilities. It means a design should be useful and appealing to people with diverse abilities, providing the same means of use for everyone whenever possible and equivalent alternatives when identical use is not feasible. The goal is to avoid segregating or stigmatizing any group of users.

Formal definition

Equitable Use is the first of the seven Principles of Universal Design, a framework for creating designs usable by people with diverse abilities. Per recognized statements of the principle, a design should be useful and marketable to people with diverse abilities by providing the same means of use for all users (identical whenever possible, equivalent when not), avoiding segregation or stigmatization, and making provisions for privacy, security, and safety equally available to all. It is a design principle rather than a legal standard or a technical conformance specification such as WCAG, and applying it does not by itself establish conformance with any accessibility guideline or compliance with laws such as the ADA or Section 508. Organizations should treat it as a design orientation and consult current standards and qualified counsel for specific compliance requirements.

Why it matters

Equitable Use establishes a foundational orientation for accessible design: rather than treating people with disabilities as an afterthought served by a separate, lesser experience, it directs designers to provide the same means of use for everyone whenever possible and equivalent alternatives when identical use is not feasible. This matters because segregated or bolted-on solutions can stigmatize the very users they are meant to serve, signaling that they are not full participants in a product or environment. When applied thoughtfully, Equitable Use encourages designs that are useful and appealing across a wide range of abilities from the outset.

For organizations, adopting Equitable Use as a design orientation can reduce the need for costly retrofits and separate accommodations by building inclusivity into the core experience. A physical example often cited is a counter or desk surface that can be raised or lowered, allowing people who stand and people who use wheelchairs to be served in the same way rather than at a separate station. The same logic extends to digital products, where a single well-designed interface can serve users with diverse needs instead of routing some users to a stripped-down alternative.

It is important to recognize the limits of this principle. Equitable Use is a design principle rather than a legal standard or a technical conformance specification such as WCAG. Applying it does not by itself establish conformance with any accessibility guideline or compliance with laws such as the ADA or Section 508. Organizations should treat it as a guiding orientation and consult current standards and qualified legal counsel to determine specific compliance obligations, which continue to evolve through regulation and case law.

Who it's relevant to

UX and Product Designers

Designers can use Equitable Use as a starting point for building inclusive experiences, favoring a single means of use for all users and providing equivalent alternatives only when identical use is not feasible. It encourages avoiding separate, lesser experiences for people with disabilities, though it should be paired with testing against recognized standards such as WCAG.

Accessibility Engineers and Practitioners

Practitioners can frame Equitable Use as a design orientation that complements, but does not substitute for, technical conformance work. Meeting this principle does not by itself establish WCAG conformance, so engineers should continue to rely on automated, manual, and assistive technology testing to identify issues.

Business and Product Leaders

Leaders may find Equitable Use valuable for setting a culture of inclusive design that reduces the need for retrofits and separate accommodations. Its emphasis that designs be useful and marketable to people with diverse abilities aligns inclusive practice with broader product goals, while recognizing it is not a compliance guarantee.

Compliance Officers and Legal Counsel

Equitable Use is a design principle, not a legal standard, and applying it does not by itself establish compliance with laws such as the ADA or Section 508. Counsel should treat it as supporting context and consult current agency guidance, regulations, and case law to determine specific obligations, which vary by jurisdiction and continue to evolve.

Inside Equitable Use

Universal Design Principle

Equitable Use is the first of the seven Principles of Universal Design, developed by a working group at North Carolina State University's Center for Universal Design. It emphasizes designing products and environments to be useful and marketable to people with diverse abilities.

Identical or Equivalent Access

The principle calls for providing the same means of use for all users where possible, and equivalent means where identical use is not achievable, so that no group is disadvantaged in how they access a product, service, or environment.

Avoiding Segregation or Stigmatization

A core component is that design should not segregate or stigmatize any users. Accommodations should be integrated rather than presented as separate, lesser, or singling-out alternatives.

Equivalent Provisions for Privacy, Security, and Safety

Equitable Use holds that provisions for privacy, security, and safety should be made equally available to all users, not reserved for some groups.

Appeal to All Users

The design should be appealing to all users, reflecting the idea that accessible design can and should serve everyone rather than being treated as a niche or specialized feature.

Relationship to Digital Accessibility

While Equitable Use is a design philosophy rather than a technical standard, it aligns conceptually with goals expressed in accessibility guidelines such as WCAG, which aim to make web content usable by people with a wide range of abilities. Equitable Use is not itself a legal requirement or a WCAG success criterion.

Common questions

Answers to the questions practitioners most commonly ask about Equitable Use.

Does equitable use mean every user must be given exactly the same interface or interaction?

No. Equitable use focuses on providing the same means of use for all users where possible, and equivalent means when identical use is not feasible. The goal is comparable outcomes and dignity, not literally identical interactions. A design that offers different but equivalent pathways can still satisfy the principle, provided no group is segregated or stigmatized and the alternatives are genuinely comparable in quality and function.

Is equitable use the same thing as complying with WCAG or the ADA?

No. Equitable use is one of the principles of universal design, which is a design philosophy rather than a legal standard or a technical conformance specification. Meeting the equitable use principle does not by itself demonstrate conformance with WCAG success criteria, nor does it establish compliance with laws such as the ADA. These are distinct frameworks; a design can reflect equitable use aspirations while still requiring separate evaluation against applicable technical guidelines and legal requirements. This information is general and not legal advice.

How can teams apply equitable use when a fully identical experience is not technically possible?

When identical use is not feasible, teams generally aim to provide equivalent alternatives that deliver comparable functionality, information, and quality. The alternative should avoid singling out or stigmatizing any group and should offer similar convenience where practical. Documenting why identical use was not possible and how the alternative achieves equivalence can help teams evaluate whether the equitable use intent is being met.

What role does equitable use play alongside standards-based accessibility testing?

Equitable use can inform design decisions early, while standards-based testing evaluates measurable conformance. Because automated testing detects only a portion of accessibility issues, teams commonly combine it with manual review and assistive technology testing. Equitable use serves as a guiding consideration during design, but it does not replace the need to verify results against recognized technical guidelines and to test with real users and assistive technologies.

How can equitable use be evaluated during design reviews?

Reviewers can examine whether the same means of use is available to as many users as possible, whether any alternative pathways are equivalent rather than lesser, and whether any group is segregated or singled out. Considering privacy, security, and safety equally across users is also relevant. Because these judgments are qualitative, they are generally strengthened by usability testing with people who have a range of disabilities.

Who typically shares responsibility for applying equitable use in a project?

Applying equitable use generally involves collaboration across roles, including UX designers who shape interaction pathways, engineers who implement them, content teams who ensure equivalence, and accessibility specialists who evaluate outcomes. Because it is a design principle rather than a codified requirement, it is often integrated into broader accessibility processes rather than owned by a single role, and it does not substitute for guidance from qualified legal counsel on applicable obligations.

Common misconceptions

Equitable Use is a legal requirement under the ADA or a WCAG success criterion.

Equitable Use is a principle of Universal Design, a design framework rather than a codified law or a technical standard. It is not a WCAG success criterion, and neither the ADA nor WCAG requires it by that name. It can inform accessible design practice, but it does not carry legal force on its own. Consult qualified legal counsel for compliance obligations.

Equitable Use means every user must interact with a design in exactly the same way.

The principle prefers identical means of use where feasible but explicitly allows equivalent means when identical use is not possible. The goal is comparable access and outcomes, not literally identical interaction for every user.

Providing a separate accessible version of a product satisfies Equitable Use.

Equitable Use discourages segregating or stigmatizing users. A separate, lesser, or singled-out alternative can conflict with the principle's aim of integrated, equivalent access, even if it technically provides some level of function.

Best practices

Aim to provide the same means of use for all users where possible, and equivalent means where identical use is not achievable.

Integrate accessibility features into the main design rather than offering separate versions that may segregate or stigmatize certain users.

Ensure provisions for privacy, security, and safety are equally available to all users.

Use Equitable Use as a guiding design philosophy alongside, not as a substitute for, established technical standards such as WCAG and applicable legal requirements.

Validate designs through manual and assistive technology testing with people of diverse abilities, since alignment with a design principle does not guarantee an accessible experience.

Consult qualified legal counsel and current regulatory guidance for compliance obligations, as design principles like Equitable Use are not themselves legal mandates.
