Donating Shouldn’t Require Target Practice

Your donor has decided to give but has your donation form decided to test their fine motor skills?  Somewhere between the tiny button and the accidental tap, a fundraising problem becomes a design problem.

In 1954, psychologist Paul Fitts demonstrated a relationship that still matters to anyone building a donation page: smaller, farther targets take longer to reach. His work became Fitts’s Law. The practical lesson is considerably simpler than the equation: give people a generous target and a short trip to it.

The visual shows five ways to put that into practice:

 

For web controls, 44 × 44 CSS pixels is a useful benchmark, drawn from WCAG’s enhanced target-size criterion. Larger controls can help further, particularly for people with limited dexterity.

These principles apply beyond the Donate button: amount choices, payment options, checkboxes and receipt preferences all require someone to hit a target.

We spend considerable time trying to understand why people don’t give. Before commissioning another theory about donor motivation, check whether giving requires unusually good aim.
