The type of font, the organization of the information, the intended audience, and the overall design can all influence the ideal font size for a website.
To improve user experience, we can use the following general parameters to establish the ideal font size:
Readability: Making sure the text is easily readable is the main objective. Most users find body text with font sizes between 16 and 18 pixels to be pleasant. Websites that cater to elderly or visually impaired users may benefit more from larger font sizes.
Responsive Design: Taking into account responsive design is crucial considering the widespread use of mobile devices. In order to accommodate varying screen sizes without compromising readability, the font size ought to be scalable.
Fonts for Headings and Subheadings: To establish a visual hierarchy and highlight significant information, use larger font sizes for headings and subheadings. For headers, a size of 24 to 36 pixels is typically appropriate.
Line Spacing: Good line spacing, sometimes referred to as leading, is essential for legibility. Generally speaking, we advise with a line spacing of 1.5 to 1.6 times the font size.
Selecting a Font: There are differences in the sizes at which different fonts look equally readable. Generally speaking, some fonts may need to be slightly larger than others in order to remain readable.
Contrast: Make sure there is enough difference between the background and the text. Enhanced reading is facilitated by high contrast, particularly for individuals with visual impairments.
User Testing: Find out whether your target audience finds the font size comfortable. We do this by doing user testing and soliciting comments from them. Because customer preferences vary, it’s critical to take your particular user base’s needs into account.
Accessibility: To accommodate users with visual impairments, take into consideration accessibility criteria such as the Web Content Accessibility criteria (WCAG), which prescribe a minimum font size of 16 pixels for body text.
A website’s body content should ideally have a font size of 16 to 18 pixels to ensure readability and appeal to a wide range of users. However, to provide your website visitors the best possible reading experience, always consider the font type, content organization, and user preferences. Remember that readability should always come first, and that depending on the demands of the audience and particular design specifications, changes can be needed.
