Text type is important because it sets the tone for the entire document. For example, a formal document such as a resume or cover letter would likely use a more traditional text type such as Times New Roman, while a more informal document, such as an email or blog post, might use a more modern text type such as Arial or Verdana.
The choice of text type can also affect the readability of a document. For example, a document with a lot of text might be more readable if it uses a sans serif text type such as Arial or Verdana.
When choosing a text type for a document, it is important to consider the audience and the purpose of the document. For example, a document intended for printing should use a text type that is easy to read at a small size, such as Times New Roman. A document that will be read on a screen should use a text type that is easy to read at a large size, such as Arial or Verdana.
Serif typefaces are generally more traditional and formal, and are often used for body text in books and other long-form documents. Sans serif typefaces are generally more modern and casual, and are often used for headlines and other short-form text. Script typefaces are more ornate and decorative, and are often used for logos and other graphic design elements.
The typeface you use for your main text should be legible and appropriate for the tone of your document. If you’re not sure which typeface to use, a good rule of thumb is to stick with a serif or sans serif typeface for body text, and reserve script typefaces for more decorative purposes.
