Why do Radio Buttons not fill the entire outer circle?












7















My question is simple:



Why do most radio buttons not fill their entire outer circle?



Example of standard radio button:



Example of standard radio button



(Unusual) Example of an entirely filled radio button:



enter image description here



Is this for some skeuomorphic reasoning or something entirely different?



Bonus Question:
Is it ever acceptable in an interface or design system to use fully filled radio buttons?










share|improve this question

























  • How would you distinguish the states of a fully filled radio button and an empty radio button? For all the user knows, you might have chosen black as the color of an empty radio button. Good UX design should be obvious, and should not require fiddling with the controls to see how they behave.

Radio buttons were inspired by the physical radio buttons ( obviously enough ). Buttons were popping out from a frame or were "3d". I would consider these as signifiers. Those signifiers made their way to the first interfaces. Practically a button popping out from a frame that when pressed would cancel all the other pressed buttons.



As of today, the radio button should also be recognizable even after it is checked. So having it according to the "standards" would be best. Even though I have seen examples of radio buttons like your example and inside the context I did identify them as radio buttons for some users it might cause some confusion or it might not but some user testing might be needed.

This is a nice article about the history of radio buttons: https://www.jitbit.com/alexblog/242-the-history-of-a-radio-button/



As said in the article:




Radio buttons are named after the actual buttons used on old radios to switch between radio waves and, sometimes, preset frequencies. When a button was pressed, all other buttons would pop out.




So, it was a skeuomorphic reason.



I believe a fully filled radio button would confuse users, based on the principle of "Match Between the System and the Real World". It states that:




Interfaces that follow real-world conventions and make information appear in a natural and logical order demonstrate empathy and acknowledgement for users.




Users are used to radio buttons in this format, so unless you have a really good reason to change that, I think you should use the standard.

    I guess a completely full radio button can be easily confused with a bulleted text:



    enter image description here



    Whereas an empty circle perceptually gives the feeling of incompleteness: needs filling or has to be filled:



    enter image description here



    Even in many cases one of these rings is already filled, which increases the feeling that they must be filled (checked):



    enter image description here

    • On your first example, the title of the "list" would probably be a question and in the list itself, only one of the option would be a black circle. The other one would be regular radios.

    • I think your best assumption is not correct, because with radio elements you would have only one radio input selected at most.

      @Devin that's not strictly true. you can have more than radio button selected if you're feeling like breaking with convention. it's not a great idea, but it's generally possible in most interfaces.

    • @worc native radio buttons ARE a convention, and a convention that motivates the question. Furthermore, to "break the convention" you would need to use checkboxes and disguise then as radio (so it wouldn't be a radio, it would be a checkbox with an image over it). Radio buttons allows for just one selected option at a time, see developer.mozilla.org/en-US/docs/Web/HTML/Element/input/radio

      @Devin you don't even have to be that clever to break conventions. just have multiple radiogroups right next to each other and a full circle is ambiguous

            • @worc native radio buttons ARE a convention, and a convention that motivates the question. Furthermore, to "break the convention" you would need to use checkboxes and disguise then as radio (so it wouldn't be a radio, it would be a checkbox with an image over it). Radio buttons allows for just one selected option at a time, see developer.mozilla.org/en-US/docs/Web/HTML/Element/input/radio

              @Devin you don't even have to be that clever to break conventions. just have multiple radiogroups right next to each other and a full circle is ambiguous

            On your first example, the title of the "list" would probably be a question and in the list itself, only one of the option would be a black circle. The other one would be regular radios.

            I think your best assumption is not correct, because with radio elements you would have only one radio input selected at most.

            @worc native radio buttons ARE a convention, and a convention that motivates the question. Furthermore, to "break the convention" you would need to use checkboxes and disguise then as radio (so it wouldn't be a radio, it would be a checkbox with an image over it). Radio buttons allows for just one selected option at a time, see developer.mozilla.org/en-US/docs/Web/HTML/Element/input/radio
