As a website owner, you should know that there are some points that should be highlighted and catch the eye of the viewer instantly. If everything were in the same font and style, the customer would be forced to look through every word of every line in order to get the gist of the content. The customer must not consider reading your page a hassle. If there is something important, it should be highlighted and attract the attention of the viewer instantly.
The point that must be noticed that the easier the font is to read, the longer the viewer is likely to stay. The slightest strain on the eyes will reduce the inclination to make the effort to read. That is a fact.
How to pick the right font
It must be readable. This is the first point - to pick the right font for your content. If it is not legible instantly or if it causes irritation to the reader, there is no point achieved.
While the default font is easy to read and the most obvious one to pick, a different style does have its own appeal. There is no need to pick a complicated font because they just do not work when there is a lot of content to read and comprehend. The idea is to be different and stand out and yet simple and elegant.
It is quite alright to pick a variety of styles for the page. The trick is in making sure that they blend and work well together. In picking styles that are too different, the elegance of the page is lost. The differences should be subtle yet noticeable.
The size of the font is just as important as the style. Too big or too small fonts can make the reader miss out on the essential messages. While you can have a variety of fonts on the same page, having more than two sizes of fonts is a bad idea. There may be exceptions but those are very rare.
The images along with the font of the content make your page. The font can be directly linked to the mood and theme of the page. A very formal or a serious page should have a sombre font while a fun page has a font that can be described as fun and happy. A heavy font stands for strength and seriousness while a light one, more decorative and light. Bold headlines reach out to you and are reserved for topics. The fine print is saved for disclaimers that most page viewers assume to be obvious. Disclaimers are usually small so that they do not take up too much space.
Font metrics should be studied in detail. The size of different elements along with the space between them and the relationship between the letters matters to a large extent. Pick a quality font and adjust the rest of the details accordingly.
Decisions must be made by looking at the whole page on the whole and not just sample paragraphs. The entire look and feel of the web cannot be judged by looking at it in parts. The bigger picture is what counts.
Get into the shoes of the consumer to see how the perspectives change. That will be your winning stroke.
