It’s 2010—Use Clickable Labels on Checkboxes

Returning to the UPS homepage I discussed in last week’s post Improving the UPS Homepage by Remembering Fitt’s Law, another problem concerns the checkbox. I’m really dismayed that it’s 2010 now and we therefore live in the future, but we’re still seeing sites not using <label> elements with checkboxes. And indeed, that is the case here—the ‘Remember this location’ label associated with the checkbox on this page is not clickable. This was also pointed out by Patrick McElhaney in a comment on the previous post.

This is another instance of where Fitt’s law applies—the tiny checkbox is a small target area for clicking, and so it makes sense to enlarge it by making the label clickable as a proxy for the checkbox itself. In desktop software on all major platforms (OS X, Linux, and Windows) the label of a checkbox behaves in just that way, and is always clickable.

I should note that, of course, on such a large site as UPS’s the changes I’ve been suggesting would have to be backed up by some A/B testing to ensure they achieve the desired effect and do not have any unintended consequences. Of course, too, UPS may be so big and critical to its customers that they would not abandon the site no matter the magnitude of its interface shortcomings. I would be willing to bet, though, that the changes would improve visitor satisfaction if not reduce abandonment, and any site can stand to increase the satisfaction of its users.

Stay tuned for one more critique of this page in an upcoming post!

Improving the UPS Homepage by Remembering Fitt’s Law

Upon navigating to the UPS homepage for the first time, you as the visitor are presented with an interstitial page asking you to choose your country and language so that you can be redirected to a localized version of the site. These interstitial pages are quite common for companies which have global operations and customers in many countries.

In the case of UPS this page is generally very understated and well-designed. One way in which it could be improved, though, is by increasing the size of the button. Fitt’s law states that the clickability of a target is a function of the target’s size. The button here is 17×18 pixels—an area of 306 pixels. That’s only 0.0236% of the screen on my 1440×900 display—two ten-thousandths of the available pixels. There’s not much else on this page taking up any space, so there’s plenty of real estate to make this change.

Critically, pages like these are barriers that potentially keep visitors from continuing further into your site. They are simply one more hurdle the user must jump over before doing what they want to do on your site. Presenting visitors with a very small (and therefore difficult to click) button is one additional thing that could lead to premature abandonment. It could be the straw that breaks the camel’s back. There’s a tradeoff between making buttons microscopically small and comically large, and I think this button could definitely be enlarged to minimize the effect of the hurdle of an interstitial page.

What do you think? What else could be improved here? Stay tuned for a couple more posts about this page.
