Icons are more than just pretty pictures. They are powerful tools for UI design that can convey meaning, express personality, and guide users without cluttering the screen.

What are icon sets and why are they important for UI design?

Icon sets are collections of icons that share a common style and theme, like fonts. You can use icons for various purposes, such as social media buttons or navigation menus.

Using icons from the same set helps you create a consistent and harmonious design that achieves its main goal: user navigation.

As a designer, you should always aim for uniformity and consistency. That’s why it’s usually better to use one icon style per project.

Using an icon set can benefit your design workflow in several ways, such as:

  • Saving you time by avoiding designing your own icons from scratch.
  • Ensuring harmony in your designs by using high-quality icon sets that match each other.
  • Providing easy-to-recognize icons that enhance your design’s appeal and intuitiveness.

How to choose the best icon sets

for your design When you are looking for an icon set to use in your design, you should pay attention to some key features that make a good icon set.

  1. They should offer both solid and line versions

Some designers prefer solid icons, while others like line icons. A good icon set should give you both options so you can decide which one suits your design better.

Solid icons tend to be more recognizable than line icons when they represent concrete objects. Line icons may work better for abstract concepts. As you gain more design experience, you will learn which type of icon fits which situation.

2. They should scale well to a consistent frame

Your icons may appear on different screens and devices, so you need to make sure they can scale well to a consistent frame size. This way, you can ensure usability regardless of how users interact with them (mouse or touch).

Also, the consistent frame size is important because not all icons have the same shape or size. You should place them in a frame that has the same proportion throughout your design to avoid scaling issues.

3. They should have enough but not too many icons

Depending on your design project, you may need a lot of icons or just a few.

Check how many icons are in a set to make sure you have enough to cover your needs. If there are not enough icons, you may have to switch to another set halfway through your design. This can break the consistency and harmony of your design.

However, you also don’t want to use a set that has too many icons. This can lower the quality of the design as the icons may become less coherent or distinctive.

Finding the right balance between quantity and quality can be hard. That’s why it’s good to use sets that are recommended by other designers, like the ones we list below.
