Browser zoom isn’t a niche behaviour

Hi again 👋

Browser zoom is one of the most commonly used accessibility features on the web. It is relied on by older customers, people with reduced vision, and anyone who needs larger text to read comfortably, to name just a few.

In other words, it is not a niche behaviour. It is a normal way people adapt websites so they can read and buy comfortably.

When someone zooms the page, they are not just making things bigger. You are changing how the layout behaves. That is often where problems start to appear.

At higher zoom levels, I regularly see:

• Text overlapping or being cut off
• Sticky headers and footers obscuring content
• Menus that become difficult or impossible to reach
• Key actions like Add to cart or Continue to checkout becoming unclear

None of these feel like “accessibility issues” to the customer. They feel like the site is broken or hard to use. And when that happens during a buying journey, confidence takes a hit. Knock it enough, and people go elsewhere.

In this video, I walk through a strong example of a product page that holds together well at higher zoom levels, alongside a couple that could be improved. The difference is not design polish. It is whether the page still supports reading, understanding, and completing the journey when the page is zoomed.

The takeaway is straightforward. Load one of your product pages, increase browser zoom, and try to read and use it as if you were seeing it for the first time. If anything feels awkward, unclear, or frustrating, some of your customers are experiencing that every day too.
