Why avoid writing everything in capital letters?

In today’s digital world, where content is king, the way that content is presented can make a significant difference to how it is received. Typography, the art of arranging text, plays a key role in visual communication. One common mistake made by content creators is the overuse of capital letters, especially in Polish. In this post, we will discuss why writing everything in capital letters is incorrect and how to best use typography to improve the readability and aesthetics of your content.

Why you shouldn’t write everything in capital letters?

1. legibility: text written solely in capital letters is more difficult to read and understand. Research shows that lowercase letters have more varied shapes, making it easier to recognise words quickly. Uppercase letters are more uniform, which means that the reader has to spend more time processing the text.

2. perception: texts written solely in capital letters are often perceived as aggressive or shouting. In online communication, where there is a lack of non-verbal context, such perceptions can be undesirable and deter audiences.

3. aesthetics: excessive use of capital letters can disrupt the aesthetics and harmony of a website. In Polish, which is characterised by the presence of diacritical marks (e.g. ą, ę, ś), capital letters may further complicate the visual perception of the text.

How to use typography effectively?

1. Hierarchy of information: Use different font sizes, thicknesses and styles (e.g. italics) to create a visual hierarchy. This will allow readers to quickly see the structure of the content and find the information they are interested in.

2 Contrast: Provide good contrast between text and background to make it easier to read. Too little contrast can make the text difficult to read, especially for people with sight problems.

3. spacing: Appropriate use of spacing between letters (kerning), words and lines of text (leading) can significantly improve readability. Text that is too tight is difficult to read, while text that is too loose can be distracting.

4 Line length: The ideal line length of text should be between 50 and 75 characters. Texts of this length are easiest to follow by eye and contribute to a better reading experience.


Correct use of typography in Polish is key to ensuring good readability, aesthetics and effective communication. Avoiding writing everything in capital letters, using a hierarchy of information, ensuring contrast, proper spacing and controlling line length are the basic principles that will help create friendly and professional-looking content.
