Final answer:
For a standard-size full-page business letter, the left and right margins should each be 1 inch wide.
Step-by-step explanation:
When creating a full-page business letter on standard-size letterhead (8 1/2 x 11 inch white paper), adhering to certain formatting guidelines contributes to a polished and professional appearance. The recommended margins for such a letter are 1 inch on both the left and right sides. This standard margin size, often set by default in most word processors, ensures a balanced layout and provides ample white space for improved readability.
For a clean and professional look, the text within the business letter should be left-justified. Additionally, it is advisable to use a legible font such as Times New Roman or Arial, set at a size 12. This font size and style combination enhances the document's readability while maintaining a formal tone.
To create a visually appealing and organized document, the business letter should be single-spaced with double spacing between paragraphs. Single spacing helps conserve space, while the double spacing between paragraphs helps distinguish different sections of the letter, contributing to a clear and structured layout.
Moreover, to align with standard business letter practices, paragraphs should begin at the left margin without indentation. This aligns with a formal and professional style, and it facilitates easier reading and comprehension for the recipient.
In summary, following these formatting guidelines, including 1-inch margins, left-justified text, a legible font, single spacing with double spacing between paragraphs, and starting paragraphs at the left margin without indentation, ensures that the business letter is not only visually appealing but also adheres to professional communication standards.
