Memo Format: The Complete Guide (With Free Template)
You need to write a memo. Maybe it’s a policy change, a meeting summary, or a request that needs to go on the record. You know it’s not an email. But you’re staring at a blank document trying to remember what goes where.
This guide covers the standard memorandum format, the parts of a memo, real examples and samples, common mistakes, and a free Word template you can download and start using right now. No account required, no email signup.
What Is a Memo?#
A memo (short for memorandum) is a written document used for formal internal communication within an organization. Use one instead of email in three situations:
The information needs to be on the record. Policy changes, formal requests, official decisions. If someone might need to reference this six months from now, write a memo.
It’s going to a large group. Department-wide announcements, company updates, anything where you need everyone to get the exact same message.
The topic is serious enough to warrant structure. Budget approvals, incident reports, compliance updates. The format itself signals that this matters.
Standard Memo Format#
Every memo follows the same basic structure. This hasn’t changed much in decades because it works.
The Header Block#
The top of every memo includes four required fields, and optionally a fifth:
TO: Who is receiving this memo. Use their full name and title, or the group name (e.g., “All Department Managers”).
FROM: Your full name and title.
DATE: The date the memo is sent. Write it out fully: “May 19, 2026.”
SUBJECT: A clear, specific summary of what the memo is about. This is the most important line in the header. “Q2 Budget Review Meeting on April 30” tells the reader exactly what to expect. “Update” does not.
CC: (Optional) Anyone who should receive a copy but isn’t the primary audience.
The labels (TO, FROM, DATE, SUBJECT) are typically bold and capitalized. Each label is followed by a colon and a tab, so the content lines up vertically. A horizontal line separates the header from the body.
The Body#
The body has three parts:
Opening paragraph. State the purpose in the first sentence. Not the second. Not after some context-setting preamble. The very first sentence should tell the reader why this memo exists.
Good: “Effective June 1, the company’s expense reimbursement policy will change. This memo outlines what’s different and what you need to do.”
The reader should know exactly what this memo is about within ten seconds.
Supporting details. This is the middle section where you provide background, context, data, or reasoning. Keep paragraphs short (three to five sentences). If you’re covering multiple topics, use section headings. If you have supporting data, reference and attach it rather than cramming it into the body.
Closing and action items. End with what you need from the reader. Be specific. “Please review the attached policy and confirm compliance by June 15” is actionable. “Please let me know if you have any thoughts” is not.
If no action is required, say so clearly: “No action is needed on your part. This memo is for your records.”
What a Memo Does Not Include#
No salutation. No “Dear” or “Hello.” The TO field handles addressing. No sign-off. No “Sincerely” or “Best regards.” The FROM field identifies the sender. No signature block. For printed copies, the sender may initial next to the FROM line.
Memo Layout, Spacing, and Font#
For anyone setting up a memo layout from scratch:
Font: Arial, Calibri, or Times New Roman. Size 11 or 12 point.
Margins: 1 inch on all sides.
Line spacing: Single-spaced body text. One blank line between paragraphs.
Alignment: Left-aligned. Do not justify or center the body text.
Length: One page is ideal. Two pages is the practical maximum. If your memo runs longer, consider whether it should be a report instead.
Real-World Memo Format Examples#
The best way to learn memo writing format is to see it in use. Each example of a memo below follows the standard memorandum format described above.
Example 1: Policy Change Memo#
TO: All Employees FROM: Sarah Chen, VP of Operations DATE: May 19, 2026 SUBJECT: Updated Remote Work Policy, Effective June 1
Beginning June 1, employees may work remotely up to three days per week, increased from the current two-day limit. This change applies to all full-time staff in roles that were previously approved for remote work.
What Changed The maximum number of remote workdays per week increases from two to three. All other remote work guidelines remain the same, including the requirement to be available during core hours (10:00 AM to 3:00 PM) and to coordinate schedules with your direct manager.
Why Feedback from the Q1 employee survey indicated that schedule flexibility was the top-requested benefit. Departments that piloted the three-day option in Q4 reported no decrease in productivity metrics.
What You Need to Do Update your remote work schedule with your manager by May 28. No changes to your equipment or access setup are needed.

Example 2: Meeting Summary Memo#
TO: Product Launch Committee FROM: David Park, Project Lead DATE: May 19, 2026 SUBJECT: May 15 Launch Meeting, Summary and Action Items
This memo summarizes decisions and next steps from the May 15 product launch planning meeting.
Decisions Launch date confirmed: July 10, 2026. Pricing will follow Tier B structure as presented in the April proposal. Marketing will lead the pre-launch campaign; Engineering will handle beta invitations.
Action Items
| Task | Owner | Due |
|---|---|---|
| Finalize landing page copy | Lisa M. | May 25 |
| Complete beta tester onboarding | James R. | June 1 |
| Submit press release draft | Amy T. | June 5 |
Next meeting: May 29 at 2:00 PM in Conference Room A.
Example 3: General Announcement#
TO: All Staff FROM: Maria Torres, Office Manager DATE: May 19, 2026 SUBJECT: Lobby Renovation, May 26 Through June 9
Construction on the main lobby begins Monday, May 26 and is expected to finish by June 9. During this period, please use the side entrance on Elm Street.
Visitor check-in will move temporarily to the second-floor reception desk. If you have client meetings scheduled during the renovation, notify your guests of the alternate entrance before they arrive.

This is the simplest memo format sample: a clear subject, one short context paragraph, one action paragraph, and a contact line. Most day-to-day memos should look like this.
The same format applies whether it’s a policy announcement, a technical memo for an engineering team, or a memo report with findings and recommendations. A technical memo format might include data tables and methodology sections. A format of a memorandum report adds structured sections (Summary, Findings, Recommendations). The header and layout stay the same.
Common Mistakes#
Burying the point. The number one memo mistake. If your reader has to get through two paragraphs of background before they learn why they’re reading, your structure is backwards. Lead with the conclusion, then provide supporting details.
Vague subject lines. “Important Update” is not a subject line. “New PTO Policy Starting July 1” is. The subject line should let someone file the memo correctly without reading the body.
Making it too long. A memo that runs three or four pages is a report pretending to be a memo. Write a one-page memo that summarizes the key points, and attach the full details separately.
Including a greeting or sign-off. Memos are not letters. The structured header replaces the greeting, and the FROM line replaces the signature. Adding “Dear Colleagues” or “Best, Sarah” signals unfamiliarity with the format.
Forgetting the action item. Every memo should end with a clear next step, even if that step is “no action required.”

Frequently Asked Questions#
What are the 5 parts of a memo?
The five standard parts are: (1) the heading (TO, FROM, DATE, SUBJECT fields); (2) the opening paragraph, which states the purpose; (3) the body, where you provide context and details; (4) the closing, which includes action items or next steps; and (5) optional attachments, referenced in the body. Some guides count the individual header fields separately, but five is the practical structure most organizations follow.
What is the difference between a memo and an email?
A memo is a formal document meant for the record. An email is a communication channel. Memos use a structured header (TO/FROM/DATE/SUBJECT) instead of a greeting, have no sign-off or signature block, and are typically distributed to groups rather than individuals. Many memos today are sent as email attachments (usually PDF to preserve formatting) or pasted into the email body with the memo attached for the official record.
Do you sign a memo?
No. The sender is identified in the FROM line. The only personal mark is an optional set of handwritten initials next to the FROM line on printed copies, confirming the sender reviewed the memo before distribution. For digital memos, this is not necessary.
How do you start a memo?
After the header block, go straight into your opening paragraph with no greeting. The first sentence should state the purpose directly. "This memo outlines the updated travel reimbursement policy, effective July 1" is a strong opening.
How long should a memo be?
One page is the standard. Two pages is the upper limit. If your content runs longer, you need a report, not a memo. For complex topics, write a one-page summary memo and attach the details separately.
What font and size should I use for a memo?
A standard professional font at 11 or 12 points: Arial, Calibri, or Times New Roman. The header labels (TO, FROM, DATE, SUBJECT) are typically bold. Some organizations use 14 to 16 point type for the "MEMORANDUM" title at the top.
What is the difference between a memo and a letter?
Memos are for internal communication within an organization. Letters are for external communication with clients, vendors, or the public. Memos use a header block, have no greeting or closing, and are shorter. Letters include a full address block, salutation, body, closing, and signature.
How do I format a memo in Google Docs?
Google Docs has a few built-in memo templates (File > New > From a template gallery), but the selection is limited. The easier option is to download our Word memo template and open it in Google Docs. Upload the .docx to your Drive, open with Google Docs, and the formatting carries over. Replace the placeholder text with your content.
