Buttons are some of the smallest elements in a digital interface, but they drive some of the most important actions. Strong button design helps users understand what to do next, tap with confidence, and move through a website or app without friction. In this guide, we’re breaking down the basic button design rules we follow at ProCreator to create clearer, more usable digital experiences.
Basic Rules for Button Design
Buttons guide action in an interface. These rules will help you design buttons that are easier to recognize, easier to tap, and easier to trust.
1. Making Buttons Recognizable
A button should signal that an action is available before someone interacts with it. Use a consistent combination of shape, contrast, placement and an action label so users can distinguish controls from surrounding content.
What makes buttons look like buttons?
Review buttons in the context of the whole screen. A control that looks obvious in a component library may disappear beside a large illustration, a dense table or several equally prominent actions.
- Shape & Size:Use familiar shapes and consistent emphasis. Filled, outlined and text buttons can all work when their purpose is clear. Shadows and rounded corners are styling choices, not proof that a control is usable. Check recognition, readable labels and the actual interaction area.
What Is a Good Mobile UI Button Size?
There is no single standard button size for every website and app. Start with the target platform, the input method and the size of the interactive area—not only the visible shape.
For web interfaces, WCAG 2.2’s Target Size (Minimum) criterion at Level AA uses 24 × 24 CSS pixels, subject to defined exceptions. Its enhanced Level AAA criterion uses 44 × 44 CSS pixels, also with exceptions. Android recommends touch targets of at least 48 × 48 dp. These are different standards and coordinate systems; CSS pixels and dp should not be presented as interchangeable measurements.
A small icon can sit inside a larger touch target. For example, an Android control can display a 24 dp icon within a 48 × 48 dp tappable area. Check the implemented hit area, not just the exported artwork. Leave room for longer labels and larger text without clipping.
Material Design Button Size: Surface vs Touch Target
When using Material Design components, distinguish the visible button container from its touch target. A component’s visual height does not, by itself, tell you whether the interactive area is large enough. Check the specification for the component and platform you implement, preserve its accessible touch target, and test any custom size overrides.
- Whitespace: Surround buttons with sufficient whitespace to distinguish them from surrounding elements, which helps improve user experience.
2. Positioning for Optimal User Flow
Place each action near the information it affects and where users expect to complete the task. A form’s main action should follow the relevant inputs; a table’s row action should clearly belong to that row.
In many left-to-right step-by-step flows, Back appears to the left of Next. This is a convention, not a universal rule. Follow the platform, reading direction and established product pattern. On mobile, check that the keyboard or a sticky footer does not cover the action.
Test realistic tasks and observe hesitation, wrong selections and recovery. Time taken is useful context, but it does not explain the problem on its own.
- Clear Labels:Use labels that explain the next action. Prefer “Save changes” to “OK,” “Create account” to a vague “Submit,” and “Delete project” when the action removes a project. Short labels such as “Next” can work when the surrounding step makes the destination clear. For consequential actions, explain the consequence rather than relying on colour alone.
3. Consistency is Key
Define button variants by role: primary, secondary, tertiary and destructive. Apply the same rules for labels, spacing, size and states wherever that role appears. A primary action should not become visually secondary on the next screen without a clear reason.
Do not make every Cancel action red. Cancelling a dialog and deleting saved data have different consequences. Reserve destructive treatment for actions that genuinely remove or damage something, and document these distinctions in the design system.
4. Hierarchy
Hierarchy helps users understand which action matters most. A primary button should stand out through size, contrast, placement, or visual emphasis, while secondary actions should remain available without competing for attention.
If every button looks equally important, users slow down and hesitate. Good button hierarchy makes the next step feel obvious, whether that action is continuing a flow, submitting a form, or confirming a decision.
5. Less is More: The Power of Limited Choices
Limit competing emphasis, not the total number of controls on a screen. A simple confirmation dialog may need only a primary action and a cancel option. A dashboard, editor, or data table may legitimately need many actions.
Group controls by task and give the most important action appropriate prominence within each group. Put less frequent actions in a clearly labelled menu when that improves scanning. Do not hide essential actions simply to meet a fixed button count.
6. Mobile Button Spacing
Assess spacing between the actual interactive areas, not just the visible button edges. Enlarged invisible hit areas must not overlap neighbouring controls. Give adjacent actions enough separation for reliable selection, especially when one action deletes or cancels work.
For web controls smaller than 24 × 24 CSS pixels, WCAG 2.2’s minimum-target criterion includes a spacing exception with a specific geometric test. It is not a universal “add a few pixels” rule. Prefer appropriately sized targets where practical, then test adjacent controls on the intended device.
7. Design Every Button State
Define each state the component needs and the message it communicates:
• Default: the action is available.
• Hover: a pointer is over the control; do not rely on hover for touch use.
• Focus: a keyboard user can identify the control they are about to activate.
• Active or pressed: the control is being activated.
• Disabled: the action is unavailable; explain the prerequisite nearby when needed.
• Loading: the request is in progress; prevent accidental duplicate submissions.
A pressed interaction is not the same as a persistent selected state. Toggle buttons need a separate on/off treatment and an accessible state. Ordinary action buttons do not need a selected state.
Keyboard and Contrast Checks for Buttons
For web actions, use a native button element where appropriate; use links for navigation. Confirm that keyboard users can reach the control, see its focus indicator and activate it. Give icon-only buttons an accessible name that explains their action.
Check label contrast separately from the visuals that identify the control. WCAG’s text criterion generally requires 4.5:1 for normal text and 3:1 for qualifying large text. Non-text contrast guidance generally requires 3:1 for visual information needed to identify a control or state, with applicable exceptions. This does not mean every decorative border must meet the same rule.
8. Providing Necessary Feedback: Keeping Users Informed
After a user clicks or taps a button, the interface should clearly communicate what happens next. This feedback can appear as a loading indicator, success message, error message, confirmation state, or progress update. Good feedback reduces uncertainty, prevents repeated actions, and helps users move forward with confidence.
For example, after “Save changes” is activated, show “Saving…” while the request is pending. Confirm success only after the save succeeds. If it fails, preserve the user’s inputs and explain how to retry. Loading feedback alone does not prevent duplicate records; the implementation must also handle repeated requests safely.
9. Button Design Checklist
Use this quick checklist to review whether your buttons are clear, usable, and effective across websites and apps.
- Make buttons easy to recognize as interactive elements.
- Use clear labels that describe the action.
- Size buttons for comfortable tapping on mobile.
- Create a clear hierarchy between primary and secondary actions.
- Leave enough space to avoid accidental taps.
- Design every button state, including focus, disabled, and loading.
- Provide clear feedback after every important action.
- Check the implemented touch target, not only the visible shape.
- Verify keyboard operation, visible focus and accessible names.
- Check text contrast and the visual cues that identify controls.
- Test long labels, larger text and loading/error recovery.
ProCreator’s Perspective: review the decision, not just the button
A button review should ask three questions: can the user find the action, predict its consequence and understand the result? A brighter fill can improve visibility, but it will not fix an ambiguous label, an unexpected destination or a missing error message.
Start with the task and the cost of a wrong action. A low-risk filter and a permanent deletion should not receive the same treatment. This is why button design belongs inside the wider workflow and design system, not only in a component styling exercise.
A Practical Example: HDFC Life
In ProCreator’s HDFC Life project, the published case study identifies back-button placement and a confusing dual progress indicator among the problems in the Basic Details flow. The redesign introduced consistent back-button placement and clearer exit routes for form completion.
The lesson for button design is specific: navigation controls need to work with the surrounding flow. A clear way back and an understandable route forward matter alongside the visual styling of each control.

FAQs
Why is button hierarchy important in UI design?
Button hierarchy helps users understand which action matters most. A primary button should stand out clearly, while secondary actions should stay visible without competing for attention. Good hierarchy reduces hesitation and makes the next step feel obvious.
What is the difference between a primary and secondary button?
A primary button is used for the main action a user should take, while a secondary button supports less important actions. The difference should be clear through visual hierarchy, such as contrast, size, or emphasis, so users can quickly understand what to do next.
Why do button states matter in UX design?
Button states help users understand what is interactive and what is happening after they click or tap. Default, hover, focus, active, disabled, and loading states all improve clarity, accessibility, and confidence during interaction.
How many buttons should you use on one screen?
In most cases, it is better to limit the number of buttons on a screen. Too many choices can overwhelm users and slow decision-making. A clear primary action and one secondary option are often enough for better usability.
