Double spacing is a formatting style used in writing where there is a full blank line between each line of text. This means that if you have a paragraph, there will be an empty line between each line of that paragraph. Double spacing is commonly used in academic papers, such as essays and research reports, to make the text easier to read and to allow space for comments or corrections. In word processing programs like Microsoft Word or Google Docs, you can easily set your document to double spacing through the formatting options. This feature is often required by teachers or institutions to ensure clarity and organization in written work.
