7 Rules for Mobile UI Button Design
Every mobile app has buttons. Unfortunately, those cute-looking and practical buttons that users love can be a nightmare for a developer. It’s not at all rare to have mobile button design botches like broken links, absence of visual feedback, and unresponsive or unclickable buttons.
There are some button design rules that can help you design better problem-free buttons.
Stick to the core UI design principles
Accessibility is the priority when designing a button. And if you want an accessible button, it has to have the right shape, size, and padding.
Shape – depends. For example, in android UI, a flat and raised material button has to be 36dp high, have a minimum width of 88dp, and have a 2dp corner radius (flat).
Size – for optimal usability and information density, Android’s Material Design advises that touch targets should be at least 48 x 48dp, with at least 8dp (or more) between them.
Padding – that’s the white space around components or content. There should be enough of it, so the users don’t get overwhelmed.
A colorful button is a good button. Color, especially contrasting colors, attracts the user and encourages them to take action. Colors are also a part of your brand identity. Therefore, users will associate the color palette you choose to use in the user interface with your brand.
When contrasting buttons, stick to the basic rules. Use low contrast for neutral actions, medium contrast for negative actions, and high contrast for positive actions.
Help users prioritize tasks by removing friction on-screen
Removing friction is one of the most important things to do. It’s essential to help users prioritize tasks. With layering, relief, and subtle shadow, you can make the 3D illusion, even on a flat screen. If you add highlights between primary and secondary buttons, the user is more likely to notice the CTA button click it.
Reward users with visual feedback
Users love excellent visual feedback. It helps them know if they’re doing something right or wrong. A perfect time to provide some visual feedback is right before the user clicks on the primary button.
Offer a free trial or sign up for the newsletter. When making visual feedback, make sure the buttons change colors as the action is accepted. In addition, some animation and motion will engage users more.
Like in life, location, position, and order are crucial, so make sure to put them in the user’s path where they can find them. If you’re making an iOS UI design, buttons must be precise and placed, so they are easy to scan and communicate the task’s priority.
When it comes to Android, it’s recommended to put one floating action button per screen to represent the most common action and emphasize its importance. In any case, use a UI pattern that compliments your content most.
For example, the F design pattern is commonly used for web content, but it may not be good for the mobile device app.
Be consistent with defining design trends as well as your UI design
While it is admirable that you want to save users a few clicks with your design, it may not be such a good idea. Above all, users love consistency. So it’s best to have consistent UI buttons. That way, users will identify them with actions and click-through.
There’s nothing more annoying for a user than a button than not knowing which button to click for further action. Make clear and distinct labels for your buttons, especially for the most important one, the CTA button.
