Indentations are the spaces left at the beginning of a line of text, often used to signal the start of a new paragraph. This formatting technique helps organize written content, making it easier for readers to follow the flow of ideas. Indentations can vary in size, typically ranging from a few spaces to a standard tab width. In many writing styles, such as APA or MLA, indentations are a common requirement. They enhance the visual structure of documents, providing a clear distinction between different sections. Proper use of indentations contributes to the overall readability and professionalism of written work.
