The interface users see and interact with on a screen.
UI (User Interface) refers to the visual and interactive elements of a product that users engage with, like buttons, menus, icons, forms, and layouts. Whether it’s a mobile app, a website, or a smart assistant, the UI is everything a user sees and touches to navigate and complete tasks.
A good UI is clear, intuitive, and makes it easy for users to do what they need with minimal effort or confusion. It also communicates brand personality through visuals, layout, and tone.
UI works with UX (User Experience) to make digital products feel natural and easy to use.
Think of UI as the steering wheel, pedals, and dashboard in a car, and UX as how it feels to drive it.
There are many types of user interfaces, including:
In localization, UI plays a big role in adapting products for global users. Translated text might be longer or shorter than the original, which can break layouts if the design isn’t flexible. Right-to-left (RTL) languages like Arabic or Hebrew require mirrored layouts. A strong design system with adaptable UI components (like in Figma) helps teams build interfaces that scale well across different languages and cultures.
Localazy helps teams create UIs that stay consistent across different languages. Our Figma plugin simplifies the process by integrating translation directly into design workflows, preventing layout issues caused by text expansion or right-to-left formatting.
