Enlarging Font Size

According to Web Content Accessibility Guidelines (WCAG) 2.0 text on your site needs to be resized up to 200 percent without assistive technology. As it states on their site:

1.4.4 Resize text: Except for captions and images of text, text can be resized without assistive
technology up to 200 percent without loss of content or functionality. (Level AA)

Does your site do this?

Try the following

To enlarge the font size use the keyboard short:

  • For Windows, Linux, and Chrome OS, press Ctrl and +
  • For Apple, press  ⌘ and +

To decrease the font size use the keyboard short

  • For Windows, Linux, and Chrome OS press Ctrl and –
  • For Apple press ⌘ and –

To return to the default font size press Ctrl and 0 on Windows, Linux, and Chrome OS

If your site does this than you have fulfilled criteria 1.4.4. I confirmed this in my conversation with Fareed Mahajana, esq. Chief Assistant (accessibility), The Commission for Equal Rights of People with Disabilities Department of Justice.

So do you need an additional font resizing toolbar on your site?

A number of plugins and web developers are offering a font resizing toolbar to add to your site.  Is this necessary and is it good practice? Adrian Roselli gives a convincing argument why not:

“Sometimes an add-on takes the form of a toolbar or widget that might adjust change contrast or allow a web page to speak its contents to you, among other features. Typically these are not built by the site owners, but are embedded from a third-party source. Often they duplicate (or conflict with) existing assistive technologies that users may already have.

Sometimes these are developed by the site developers, commonly in the form of text sizing widgets or color switchers. There are some common interface elements (such as a button with a larger letter or plus sign, and another with a smaller letter or minus sign), but for the most part these are different from site to site.”

You need to build a site that will work with assistive technology – not add widget’s to your site.  Click here for the full article  “be wary of add on accessibility“.

At this time you will find many Israeli sites adding a font resizer on their site – it is not clear why as browsers are improving and resolving many accessibility issues.  I am trying to find out what the motivation is.  If you know – pass it on.
