Fixed width text format is a type of text format that assigns a specific character length to every character. In other words, all the characters (including spaces) take up the same amount of horizontal space in the document, making it easier to align content for display on certain screen sizes. It is useful for displaying information such as dates, times, money, addresses and telephone numbers. Some databases and software programs require data to be in a fixed width format in order to read it correctly, and there are many tools available to convert text into that format.
