Do you get complaints that the copy on your website is too small?

First, make sure that you have not disabled the customer's ability to control font size from their browser toolbar. This allows your savvier customers to easily change font sizes whenever necessary.

However, for the rest, who haven't a clue that it's even possible to change font size, consider adding a utility to your navigation menu that automates the process.

HSBC's UK website features the above utility box on most interior pages, with the exception being the homepage. Not only can users easily increase/decrease text size (note the use of user-friendly language), they can also print the page or click through to the customer service contact center (itself a model of user-friendliness).
