Scaling Images

Difficulty: Advanced

Category:

  • Presentation

Users with low vision often use a screen enlarger to increase the size of elements in a web page. Images can become pixelated or blocky when they are enlarged. Text within images can become particularly difficult to read. When you can get the same visual presentation using real text, you should use it instead of text within images. When images that contain text are used, ensure that the text remains readable when the image is at least doubled in size. Using sans-serif fonts and adequate contrast makes enlarged text in images more readable.
