Proper spacing for a letter is single-spaced lines with a blank line between paragraphs, and specific margins (usually 1 inch) on all sides. For a business letter, use one space after punctuation, a blank line between the date, inside address, salutation, body paragraphs, closing, and signature block.
Why Spacing Matters in Letters
Spacing is not just about looks; it affects readability and professionalism. In a business or formal letter, consistent spacing signals that you understand standard correspondence etiquette. A cluttered letter with inconsistent gaps is harder to read and can make a poor impression. For personal letters, spacing is more flexible, but the same principles of clarity apply. The standard block format, used in most business letters, relies on left-aligned text and blank lines between sections to guide the reader’s eye.
Standard Spacing Rules by Letter Type
Different letter types have different conventions. Here are the most common:
- Business letters (block format): Single-space the text within paragraphs, and add one blank line (which is equivalent to one empty line) between paragraphs. Use one blank line between the date, recipient’s address, salutation, body, closing, and signature. Margins are typically 1 inch on all sides.
- Business letters (modified block): Same as block, but the date, closing, and signature are aligned to the right or center. Spacing between sections remains one blank line.
- Personal letters: Single-space paragraphs, with a blank line between paragraphs. You can also indent the first line of each paragraph instead of using blank lines. Margins can be wider, but 1 inch is still a safe default.
- Formal invitations or announcements: Often use more generous spacing, such as double-spacing between lines of text, to create an airy, elegant feel. But this is a stylistic choice, not a strict rule.
How to Space a Business Letter Step by Step
Follow this sequence for a standard one-page business letter in block format:
- Set margins to 1 inch on all sides (or at least 0.75 inch).
- Type your address (or use letterhead) at the top. If using plain paper, place it at the top left. Press Enter once after the last line of your address.
- Leave one blank line (press Enter twice) before the date.
- Type the date (e.g., June 1, 2025). Leave one blank line after the date.
- Type the recipient’s name, title, and address. Leave one blank line after the last line of the recipient’s address.
- Type the salutation (e.g., “Dear Ms. Smith:”). Leave one blank line after the salutation.
- Type the body of the letter. Single-space within paragraphs. Leave one blank line between paragraphs.
- After the last paragraph, leave one blank line, then type the closing (e.g., “Sincerely,”).
- Leave three to four blank lines for your handwritten signature, then type your name. If you have a title, type it on the next line.
Common Spacing Mistakes and How to Fix Them
One frequent error is using double-spacing between paragraphs instead of a single blank line. Double spacing is for drafts or academic manuscripts, not final letters. Another mistake is inconsistent spacing after the salutation or closing. Always use one blank line. Also, many people use the Tab key to indent paragraphs in a business letter, but block format requires no indentation. If you choose indented paragraphs (common in personal letters), be consistent—indent every paragraph by 0.5 inch, and do not add blank lines between paragraphs. Finally, avoid using extra spaces after periods; one space is the modern standard for all typed documents.
Spacing in Email vs. Printed Letters
Email correspondence follows similar spacing rules but is more relaxed. In an email, you still use a blank line between paragraphs, but you can skip the inside address and date. The salutation and closing are still separated by a blank line. For a printed letter, the physical spacing affects the overall length; for an email, the screen does the same. Always use a standard font (like Arial or Times New Roman) at 11 or 12 points, and keep line spacing at single or 1.15 for readability.

Frequently Asked Questions
Should I use one or two spaces after a period?
Use one space. The two-space rule comes from the typewriter era; modern word processors and fonts are designed for a single space. Double spaces can create uneven gaps in justified text.
What is the standard margin for a letter?
One inch on all sides is the standard for business letters. For personal letters, you can use 1 to 1.25 inches. If you need to fit more text, you can reduce margins to 0.75 inch, but not less.
Do I need a blank line between the date and the recipient’s address?
Yes, in block format, you leave one blank line after the date before the recipient’s address. This helps separate the date from the address visually.
How many blank lines for a signature?
Leave three to four blank lines between the closing (e.g., “Sincerely,”) and your typed name. This gives you room to sign your name by hand. If sending electronically, you can use a digital signature or just type your name.
Is it okay to indent paragraphs in a business letter?
No, in block format, paragraphs are not indented; you use a blank line between them. Indenting is acceptable in personal letters or in a semi-block business format, but block format is the most common and professional.
What if my letter is longer than one page?
Use the same spacing rules, but include a header on the second page with the recipient’s name, page number, and date. Leave a blank line before continuing the body. Do not staple; use a paper clip if needed.
Final Tips for Perfect Letter Spacing
Before sending, do a visual check: the letter should look balanced, with no large gaps or cramped sections. Use the print preview function to see how it fits on the page. If you are unsure, stick to the standard block format with 1-inch margins and single spacing. For personal letters, you have more freedom, but consistency is key. If you are writing a formal letter for legal or official purposes, consider asking a qualified professional to review it, as specific requirements may apply.
