Which Fonts Should be Used in Interface Design?


One of the most important elements of interface design is typography. Using the right typography can significantly improve the user experience. Users consume content more easily and can interact more. Type styles affect the readability, aesthetics and user experience of texts. 

In an interface, texts often enable users to get information, give instructions or facilitate interaction by conveying the brand’s message. Therefore, the choice of fonts is of great importance to ensure that users can easily read and understand the text, present an aesthetic appearance and enhance the user experience

Let’s take a closer look at the importance of using fonts in interface design and the effects of different fonts!

What Should Be Considered When Using Fonts in Interface Design?

The following should be considered when using different writing styles in interface design;


Font Selection

The different fonts chosen should be appropriate for the purpose of the design, the target audience, and the brand identity. Font selection is very important for the success of an interface design. Choosing a font that will reflect the brand’s personality, emphasize its values, and meet the expectations of the target audience will increase the impact of the design and improve the user experience. For example, there will be a difference between a design for children and a news site. While a more rounded font will be chosen for children, a more serious font will be chosen for the news site.

Number of Fonts

A minimum number of fonts should be chosen to make the design look organized. Choosing a maximum of two families will help you maintain consistency. One can be used for headings and the other for other text. If there is a large font family, a single font can also be used. This will make our design look better. Using too many different typefaces will complicate the design and create an inconsistent look.



The font chosen should not only align with the brand identity but also with the content. Each font has a specific character and style and should match the tone, purpose, and message of the content. For example, there will be a big difference between the font used for a formal corporate document and the font used for a promotional page for a creative and fun product. Also, if more than one font is used, there should be harmony and consistency between them. 

Transitions and combinations between fonts should be carefully considered and chosen to create a harmonious look. Characteristics such as the style, weight, height, and width of fonts should be compatible with each other. This consistency helps the design make a professional and balanced impression. As an interface designer, some methods can be used to achieve harmony between fonts. 

For example, consistency can be achieved by using different variations of the same font family (bold, italic, light, etc.). In addition, the orientation, spacing, and alignment of font typefaces should also be compatible. These are important factors in creating a cohesive and consistent interface design where different fonts work together and provide a holistic design experience.


Since there are different areas such as title, text, and buttons in the interface design, the text has to be used in very different sizes. The design can also be viewed on small screens and should be designed accordingly. For this reason, the font chosen should be readable at any size. Whether it is a large headline or a small sub-text, users should be able to easily read and understand the text at any size. The font should remain clear and distinct even when the size is reduced.


The main purpose of the font is to make the text easy to read. A font that users can read comfortably should be chosen. Letters should be clear and distinct in font writing styles. Sans-serif fonts are generally preferred to increase readability. This type of font provides clarity and readability because it has simple and straight lines. 

Serif fonts, on the other hand, can have a more traditional look and, in some cases, affect readability. However, both font types can provide an effective reading experience when used correctly. Choosing aesthetic fonts that users can read comfortably, with clear and distinct lettering, enhances the user experience and ensures that text content communicates effectively.

Contrast is also a factor that affects readability. Sufficient contrast between the font style and the text background makes the text more distinct. It helps users distinguish text more easily with their eyes.


Language Support

Make sure that the design works properly in different languages. Considering that each language has its own unique characters, letters, and grammar, the design should be created to cover these differences. For example, it is important that an interface designed in English be properly displayed and understood when translated into Turkish or any other language. 

Therefore, the font chosen should support Turkish characters. It is important that letters used in Turkish such as “ğ”, “ş”, “ü”, “ı”, “ö”, “ç” are represented correctly in font styles. Choosing the right font, its suitability for language features, and the expandability of text areas ensure that the design is effective and user-friendly for users of different languages.

To summarize; 

  • The use of fonts in interface design is a critical element that affects the user experience.
  • Choosing the right font styles increases the readability of texts, provides an aesthetic appearance, and allows users to easily consume content. 
  • The font selection should be appropriate for the purpose of the design, target audience, and brand identity
  • It is important to pay attention to factors such as font size, compatibility, readability, contrast, and language support. 
  • Inconsistency, overuse of fonts, or ignoring language features can negatively impact the user experience.
