Line Length
The line length is the number of characters on a single line of text. 60 to 80 characters per line are ideal line length for English text for any UI. 30-40 characters are ideal for mobile devices. Choosing the right line length not only impacts a website's design but also increases its readability. Line length rules are also applicable for headings.
Solution
Keeping your line length more than 100 characters makes it difficult to read and worsens interest in the content. If you want to keep long texts you need to adjust the font size. The smaller your font size is the narrower your column width has to be to avoid over 75 characters.
Summary
Choosing the right line length is a crucial part for every web design and text. Avoiding line length rules will make the website unattractive and significantly worsen the user experience.
