New Beginnings

Radio buttons and checkboxes have long been components that cause users confusion. These components are often used in the same context, but look completely different. Designers and developers know the difference, but that’s because they learned it through their work. What about users who were never taught the difference?

The fact that users need to be taught the difference shows that these two components are not intuitive. Their appearance alone does not convey their slight differences in functionality. The visual cues themselves—a dot and checkmark—carry no specific meaning to users other than an option selection. Therefore, the existence of both radio buttons and checkboxes violates the UX principle of Consistency.

Designers and developers have never questioned their co-existence because it’s the way it’s always been. However, if their co-existence causes users confusion and violates a UX principle, it merits a logical analysis and rethinking.

A Violation of Consistency

The UX principle of Consistency states that components with similar functionality and same usage should have a uniform appearance. Radio buttons and checkboxes have a similar function and are used in the same context, but there’s nothing uniform about their appearance.

Mutual Exclusivity/Inclusivity Is Not a User Concern

If you ask the typical user what a mutually exclusive or inclusive option is, they probably wouldn’t be able to tell you. That’s because they don’t think about mutual exclusivity or inclusivity when they use an interface. Only designers and developers think about this because they have to design the interface.

Users merely read the labels and select the options they want. They’re focused on what the labels say, not component functionality. Therefore, mutual exclusivity and inclusivity should be indicated in the labels they read, not the components themselves. Designers and developers are imposing their way of thinking onto the user.

How Users Know They Can Select One or Multiple

The label on the components often indicates whether users can select multiple options or just one. When users can select multiple options, the label is worded in plural form. When users can only select one option, the label is worded in the singular form. Make sure you use the correct noun form when you label mutually exclusive and inclusive components. It’s easy to forget about the labels, but they’re what matters most.

Use Check Circles Instead

Users need a component for selecting from a list of options that’s uniform and consistent. Instead of using radio buttons and checkboxes, use check circles for both instead. A check circle combines both the outer shape of a radio button with the checkmark cue of a checkbox.

When there’s a single component for selecting option lists, users are no longer distracted by the differences between radio buttons and checkboxes. They can focus more on the labels and choose options that fit them best. It doesn’t matter whether users can select only one or multiple options. They’re going to make selections based on what the label dictates, not the type of component.

Old Design Practices Evolve

Radio buttons and checkboxes have co-existed for a long time. Some may use their longevity to justify their co-existence. However, many old design practices of the past have since evolved due to a better understanding of UX. For example, reset buttons that clear forms, red asterisks on required fields, and password confirmation fields have nearly all faded away today. Radio buttons and checkboxes may soon do the same because, like most things in life, interface design continues to evolve.
