When choosing a font for a website, several factors should be considered. Firstly, the font must be legible on different devices and screen sizes. It should also align with the website's overall design and brand identity. Additionally, the font style and size must be appropriate for the content and target audience. Considering the load time and accessibility of the chosen font is essential too. Lastly, compatibility with various web browsers and the availability of web-safe fonts should be taken into account.
