Typography is a foundational element of design because it directly impacts how users read and engage with content. A clear and consistent typography hierarchy is essential for guiding the reader’s eye through a piece of content. This hierarchy helps prioritize important information and makes the text easier to navigate.

For example, leading in typography (the space between lines of text) plays a crucial role in text readability. Too little leading makes text feel cramped, while too much makes the content feel disconnected. It’s important to get the balance right for the content to flow smoothly.

When designing for different platforms, such as web or mobile, customizing typography is essential. Many designers turn to tools like Google Fonts for easy integration and customization, ensuring that the typography fits well with the overall design. For mobile interfaces, a mobile UI kit provides ready-made typography styles optimized for smaller screens.

In modern design frameworks like Material UI, typography is used to ensure consistency across the user interface. Whether you're working on a website or a brand’s visual identity, understanding the key elements of typography helps designers create more effective and engaging user experiences.
