How do you make a website easy for older customers to read and use?

Ascent Vision · Published October 25, 2026

Let text enlarge without breaking the page, keep strong contrast between text and background, write links that say where they go, give people enough time, and keep forms short with clear labels and error messages. W3C, which publishes the web's accessibility guidelines, says its existing standards address most older users' needs, so changes made for people with disabilities also help older customers. They usually help everyone else, too.

Why older visitors struggle

W3C's page on older users lists age-related changes that affect how people use the web, including reduced contrast sensitivity and near focus, reduced dexterity that makes small targets hard to click, and reduced short-term memory that makes navigation and online tasks harder to follow. It says websites that are accessible to people with disabilities are more accessible to older users as well.

What W3C's guidance points to

Text size: W3C's guide for developing sites for older people cites the WCAG criterion that text can be resized up to 200 percent without loss of content or function, and lists large fonts by default among the techniques to consider.
Contrast: the WCAG minimum is a ratio of at least 4.5:1 for normal text and 3:1 for large text, which W3C's contrast page defines as 18 point, or 14 point bold. That page says the 4.5:1 level offsets the contrast loss of about 20/40 vision, which it says is commonly reported for people around age 80.
Links: link text that says what the link is for, and links that look different from plain text.
Time: people can turn off, adjust or extend any time limit, because some older people take longer to read and finish tasks.
Distractions: a way to pause moving content, and care with pop-ups and new windows, which the guide says can confuse or distract some older people.
Forms: labels or instructions for every field, and errors that are identified and described, with a suggested fix where one is known.

Checks with an older customer in mind

The related answer on whether your website is accessible covers the general checks, such as zooming in and testing the form. For older customers in particular, tap every button with a thumb rather than a fingertip, make sure the phone number sits near the top and starts a call when tapped, and ask an older customer or relative to book something while you watch, without helping.

The same changes help everyone

This page is about the older customer in particular. The related answer on whether your website is accessible covers the Justice Department's guidance and the common barriers, and the related answer on reading level covers plain wording. Larger text, plain labels and a visible phone number usually help anyone reading on a small screen or in a hurry, too.

Websites, upgraded or built

Most businesses do not need a new website. They need the one they have to load fast, say clearly what they do and ask the visitor to take one step.
