Magnification

People may magnify the screen or change window size and orientation to support low vision or reading on a smaller device.

To ensure equal access and a positive user experience, it is important that digital content can be enlarged without loss of information or functionality, and without requiring scrolling in two dimensions. When digital content adapts to different screen sizes and orientations, this is called reflow.

Be sure to use high-quality, high-resolution images that won’t become fuzzy or pixelated at higher levels of magnification, and avoid using images of text.

For any digital content that can be accessed via web browser, zoom in using the browser’s magnification tool and check that content resizes and reflows properly without getting cut off or requiring horizontal scrolling. Test content at various window widths and magnification levels — you should be able to zoom in up to 400% without encountering problems.

• Use high-quality images that won’t blur when magnified
• Avoid using images of text
• Give enough space between lines, paragraphs, and images to support magnifying content
