Get Site Visitors to Click On Your Buttons

Buttons are essential components in any digital product. While there are many ways to design a button, designers must follow principles and best practices to create familiar and intuitive user experiences.

Button design is more than choosing a shape and color. Designers must consider a button’s states, placement, size, responsiveness, consistency, icon usage, suitable text/labels, and more.

What is the Purpose of a Button in UI Design?

While this might seem like an obvious question to experienced UI designers, many digital products still misuse buttons. Buttons convey a specific call to action (CTA), like “Submit” or “Pay.”

Buttons tell users, “if you click me, something will happen.” Designers also use buttons to communicate with users through states, color, and text. For example, a disabled button state (unclickable) remains until the user completes a form’s required fields.

Many digital products and websites use buttons and links incorrectly. There is a simple rule to follow when deciding between a button or link: Links are for navigation, and buttons are for performing actions.

4 Types of Button Design

There are four types of buttons designs, and each button conveys a different message to users:

  • Contained Button: Often used as the primary button for CTAs and important actions. Contained buttons use a background color with contrasting text.
  • Outlined Button: Also referred to as a secondary or ghost button, and often placed next to a primary button as an alternative action, like “Cancel” instead of “Submit.” Outlined buttons use a transparent background with a contrasting border and text.
  • Text Button: Also called a flat button and often used for low important actions, like date pickers. Text buttons have no background or border, with only the label colored and visible.
  • Toggle Button: Designers use toggle buttons for two or more related actions–like switching dark/light mode on an app or bold, italic, and underline in word processors. Designers use states to indicate which option is active.

Modern mobile apps also use a floating action button (FAB) for important actions. Designers often place FABs at the bottom of the screen so that it’s a thumb’s reach from the user.

UI Button Anatomy

Designers and engineers can modify several button properties:

  • Label
  • Icon
  • Padding
  • Margin
  • Border
  • Border radius
  • Drop shadow

6 UI Button States

Designers use states to provide context and communicate with users. There are six types of button states:

  1. Default: How a button looks without any state. A default button could be contained, outlined, or flat, depending on your UI design and design system
  2. Active: Tells the user they have pressed the button
  3. Hover: Activated when a mouse cursor hovers over a button. Hover tells the user this is a clickable element
  4. Focus: Used to indicate selection when using the keyboard or assistive technologies
  5. Disabled: Indicates the user can’t click the button until completing another task
  6. Loading: Communicates the system is processing the user’s action

Best Practices for Using & Designing Buttons

Designers must follow certain principles for designing buttons and user interfaces. Use these button design best practices to guide your next project.

Button Hierarchy and Placement

Designers must consider button hierarchy and placement to provide users with clarity and highlight the most important action. Google’s Material Design recommends designers must create emphasis through color:

  • High emphasis (Primary): Use a bright color, preferably a contained button, to show this button is most important. Avoid using more than one high-emphasis button on a single screen.
  • Medium emphasis (Secondary): Use a lighter shade of your high-emphasis color to signify this button is less important. 
  • Low emphasis (Tertiary): Use a text button or outlined button with a transparent background to show users its low importance.

By applying button hierarchy principles, users can complete important actions without much thought. If you use a single button for every action, users will have to examine each to determine which one they must press.

Correct button placement is also essential to guide users through a digital product. If you place two buttons side-by-side, always use a contained button as the primary action and outlined or text button for the secondary action. 

For example, if you have “Save” and “Cancel” at the bottom of a form, “Save” would be the primary action with the higher emphasis.

Button Consistency

Designers must use buttons consistently throughout a digital product. If you use a contained button for a primary action on one screen, repeat this choice throughout.

Designers must also be consistent with button sizes, fonts, icons, colors, border radius, whitespace, and other properties to create a familiar user experience that’s easy to navigate.

Button Sizing & Spacing

Size matters when it comes to buttons, especially on mobile applications where users use their fingers. Designers must use appropriate button size and spacing to ensure users don’t accidentally hit another element. 

Designer Taras Bakusevych recommends making UI elements a minimum of 48×48 pixels to avoid touch target errors. 

Button Labels

Labels should be as short and meaningful as possible. Designers must also keep labels on a single line for legibility. 

Button text language is also critical for conveying the correct message and action to users. For example, if you’re removing a song from a playlist, the correct phrasing would be “Remove” instead of “Delete.” Delete might confuse the user into thinking they’re deleting the song from their device or application.

Capitalization is also a critical factor designers must consider. Google Material Design recommends using uppercase for languages that allow it, while UX Movement says to use sentence-style capitalization.

The argument for sentence-style capitalization is better for users with reading disabilities like dyslexia. Google reasons that uppercase “is to distinguish the text label from surrounding text.”

The best option is to test your product with users. Color, contrast, size, UI layout, and many factors impact legibility, so there is no one-size-fits-all for capitalization.

Button Accessibility

Accessibility is a critical factor in modern UX design and product development. Designers must test UIs using tools and diverse usability participants to ensure buttons and other UI elements meet accessibility standards.

The color contrast between the label and background is one of the biggest considerations for button accessibility. With UXPin’s built-in accessibility features, designers can test color blindness and contrast on the fly–keeping them focused in UXPin rather than turning to external tools.

Label size, spacing, and padding can also impact accessibility. These properties are harder to test using tools, so designers must use usability testing to get meaningful results.

Devices & Screen Sizes

Recognizing how buttons look across different devices and screen sizes is crucial for designers. For example, dialog boxes look completely different on Apple devices compared to Android. The floating action button also looks different on iOS vs. Android.

Designers also need to consider how buttons will appear across multiple screen widths. For example, a button with a long label might not look the same on mobile vs. desktop.

Designing Buttons in UXPin

Designing buttons using an image-based design tool can be challenging. The static nature of image-based tools means buttons lack interactivity, functionality, and fidelity.

With UXPin’s code-based design tool, designers can create authentic user experiences with components that look and function like code. Here are some of UXPin’s advanced features to enhance your button design.

Components

Designers can build buttons from scratch and save them as Components to reuse throughout the design. Designers can also share these components through a shared design system to maintain consistency throughout the team.

States

UXPin States allow designers to create multiple states for a single UI component, like a button. For example, you can design the six-button states mentioned above, each with different properties that change according to user and system actions.

Designers can also use UXPin’s States for other components like carousels, dropdown navigation, accordions, and more.

Interactions

Create code-like interactivity using UXPin’s Interactions. Designers can choose from an extensive list of triggers and actions for desktop and mobile interactions. 

UXPin takes interactivity one step further with Conditional Interactions, allowing you to create dynamic, unique experiences based on user and system actions.

Variables & Expressions

With Variables and Expressions, designers can build high-fidelity prototypes with interactivity mirroring code.

For example, using UXPin Variables, designers can create a dynamic pay button that displays a variable total from a shopping cart, “Pay $25.”

You can also use Variables to create a personalized user experience during testing, like a welcome message with the name from user input or populating a profile page.

With Expressions, designers can validate form fields, like emails and passwords, and even disable a button until the user completes a form’s required fields.

With UXPin’s advanced prototyping features, the possibilities are endless. Designers can design prototypes that look and function like code, saving countless hours developing an identical prototype simply for testing purposes.
