Icons may be small, but they play a big role in UI design. This article covers how to choose, style, and apply icons effectively to support clarity, consistency, and usability.

1. Icons support not replace

Icons are meant to improve clarity and guide users—not leave them guessing. If an icon’s meaning isn’t immediately recognizable to most users, pair it with a text label. This is especially important in navigation menus, where clarity directly affects usability and user flow. A simple label can prevent confusion and create a smoother, more intuitive experience.

2. Consistency is the key

Try to stick to one icon package whenever possible to maintain a cohesive visual identity throughout your interface. If you do need to combine multiple sources, make sure the icons share consistent stroke widths, corner radii, and overall visual construction. Any variation in style should be intentional—for example, using filled icons for active states and outlined icons for default states—not accidental mixing that can make the UI feel unpolished or chaotic.

3. Components in Figma

Make sure all icons in your Figma project are set up as master components. This allows you to effortlessly reuse them across buttons, menus, or form elements while keeping styling changes consistent through variables or component properties. By defining them once, you maintain full control and ensure every update flows through the entire interface automatically.

4. Master styles

Be creative in your icon choices—different styles can express personality, tone, and visual identity. However, once you commit to a style, stay consistent in line weight, shape language, and level of detail to maintain a clean and unified interface.

5. Icon packages

There are many high-quality icon packages that can help you maintain consistency and speed up your workflow. Choose a set that matches your design style, supports multiple weights, and includes a wide range of functional icons.
