If you’ve got a stack of mail to send out, the first thing you probably want to know is how to actually print addresses on envelopes without wasting half the stack. Open Microsoft Word, head to Mailings > Envelopes, type in the delivery and return addresses, click Options to match your envelope size, load a single envelope into your printer’s manual feed tray, and hit Print. Because your software needs to know the exact dimensions it’s printing onto, running one test envelope first is what separates a clean batch from a pile of crooked, off-center rejects.
In this guide, we’ll walk you through every part of the process step by step, cover envelope sizes and loading orientation, explain how to format an address the way postal equipment expects to read it, show you how mail merge turns an afternoon into a few minutes, and point out where a desktop printer stops being enough. So let’s dive deeper into the details.

What You Need Before You Start
Get these five things ready before you print anything. It saves envelopes.
- A printer that handles envelopes. Check your manual. Most inkjet and laser printers can do it, but a rear or manual feed slot gives you far better results than a standard paper tray.
- A stack of blank envelopes. Smooth, matte stock feeds better than glossy or heavily textured paper.
- Word processing software. Microsoft Word, Google Docs, or LibreOffice all work.
- Your addresses, typed out. A spreadsheet is ideal if you are sending more than a handful.
- A few spare envelopes for testing. You will want them.
Common Envelope Sizes for Printing
Picking the wrong size in your software is the most common reason addresses Print in the wrong spot. Match your setting to the physical envelope in your hand.
| Envelope | Dimensions | Best For |
| #10 | 4.125″ x 9.5″ | Business letters, invoices, statements |
| #9 | 3.875″ x 8.875″ | Reply envelopes |
| A7 | 5.25″ x 7.25″ | Invitations, greeting cards |
| A2 | 4.375″ x 5.75″ | Notecards, RSVPs |
| 6″ x 9″ | 6″ x 9″ | Booklets, unfolded documents |
| 9″ x 12″ | 9″ x 12″ | Catalogs, flat documents |
| C5 | 162 x 229 mm | Folded A4 (international) |
| C6 | 114 x 162 mm | Folded A5 (international) |
| DL | 110 x 220 mm | Standard European business mail |
The #10 is what most US businesses use. If you are unsure, measure the envelope rather than guessing.
How to Print on Envelopes in Microsoft Word
Word has a built-in envelope tool, and it is the simplest path for most people.
- Open Word and click the Mailings tab.
- Click Envelopes in the Create group.
- Type the recipient’s address into the Delivery Address box.
- Type your address into the Return Address box. Check the box marked Omit if your envelopes are pre-printed with a return address.
- Click Options, then the Envelope Options tab, and select your envelope size from the dropdown. Choose “Custom size” if yours is not listed.
- Still in Options, click the Printing Options tab. Pick the feed method and orientation that match how your printer takes envelopes.
- Click Add to Document to save the layout, or click Print to send it straight to the printer.
You can adjust the Font here, too. Click Font under either address box to change the typeface or size.
How to Print Envelopes Without Word
No Word license? Google Docs handles it, though you set the page size manually.
- Open a new Google Doc and go to File> Page setup.
- Switch the paper size to Custom and enter your envelope dimensions. For a #10, that is 9.5 x 4.125 inches. Set orientation to Landscape.
- Set all four margins to 0.5 inches.
- Type the return address at the top left and the delivery address roughly in the center.
- Go to File> Print, and confirm the paper size in your printer dialog matches the envelope.
LibreOffice Writer has a dedicated envelope tool under Insert > Envelope if you prefer a guided setup.
How to Load Envelopes in Your Printer
This trips up more people than the software does. Loading orientation varies by manufacturer, so your printer’s manual is the final Word. Here is the general pattern:
- HP: Face down, flap on the left, short edge in first.
- Canon: Face up, flap on the left, long edge in.
- Brother: Face down in the manual feed slot, flap facing up.
- Epson: Face down, flap edge leading, short edge in first.
Most printers have a small icon molded into the tray or feed slot showing correct orientation. Look for it before you guess. Adjust the paper guides so they touch the envelope without pinching it, and load one envelope at a time for your first attempt.
How to Format the Address Correctly
Clean formatting is not just about looks. Mail-sorting equipment reads your envelope, and a poorly placed address can slow delivery.
- Delivery address: Centered on the envelope, left-aligned within its block.
- Return address: Top left corner.
- Font: Simple and readable. Arial, Helvetica, or Calibri at 10 to 12 points.
- Case: All capitals scans best, though standard capitalization is accepted.
- Punctuation: Leave commas and periods out of the address block.
- Margins: Keep at least half an inch of clear space on every side.
- Last line: City, state abbreviation, and ZIP code on one line.
How to Address a Large Envelope
Large envelopes, called flats, follow slightly different rules than letter-size mail.
Position the envelope so the longest side runs horizontally. Place the delivery address in the upper portion, roughly centered left to right, and put the return address in the upper left corner above it. Leave the bottom inch of the envelope completely clear, since postal equipment uses that strip for barcodes.
If your printer cannot feed a 9″ x 12″ flat, print the address onto a shipping label and apply it instead. The formatting rules stay the same.
How to Print Multiple Envelopes at Once
For anything past ten or fifteen envelopes, mail merge saves real time.
- Build your list in Excel. Use separate columns for Name, Address Line 1, Address Line 2, City, State, and ZIP. Put headers in row one and save the File.
- In Word, go to Mailings > Start Mail Merge > Envelopes. Set your envelope size and click OK.
- Click Select Recipients > Use an Existing List and pick your spreadsheet.
- Click into the address area, then Insert Merge Field, and add your columns in the order you want them printed.
- Click Preview Results and page through a few records to check for gaps or misalignment.
- Click Finish & Merge > Print Documents.
Print the first two or three, check them, then run the rest.
Troubleshooting Common Problems
| Problem | Likely Cause | Fix |
| Text prints crooked | Paper guides are too loose | Snug the guides against the envelope |
| The address is off-center | The wrong size was selected in the software | Re-check Envelope Options against the physical envelope |
| Ink smudges | Glossy or coated stock | Switch to matte, uncoated envelopes |
| Envelope jams | Flap catching in the feed path | Tuck the flap in, or use the manual feed slot |
| Print is faded | Low ink or wrong media setting | Replace the cartridge and set media type to “envelope” or “thick paper.” |
| Only part of the address prints | Margins too tight | Increase margins to at least 0.5 inches |
When a Desktop Printer Isn’t Enough
Everything above works well for occasional mailings. But there is a point where feeding envelopes one at a time stops being a workflow and starts being a bottleneck.
If you are printing hundreds or thousands of envelopes regularly, or you want full-color graphics and logos rather than plain black text, a dedicated envelope printer changes the math. At TCS Digital Solutions, we carry Afinia envelope printers, the CP950 and CP950 Plus, built on the Memjet Sirius print engine for exactly this kind of work. The CP950 handles monthly duty cycles up to 350,000 envelopes and produces up to 9,000 #10 envelopes per hour at resolutions up to 1600 DPI. Print full color directly onto envelopes, cardstock, boxes, and padded mailers up to 10 mm thick and 40 inches long.
The CP950 Plus adds water-resistant ink, which matters if your mail passes through humid conditions or outdoor delivery.
A machine like this is not for the office that mails twenty letters a week. It is for mailhouses, print shops, and businesses running regular high-volume campaigns. If you are not sure which side of that line you fall on, ask us. We would rather point you to the right fit than sell you more printer than you need.

Wrapping Up
Printing addresses on envelopes comes down to three things: match your software settings to the physical envelope, load it the way your printer expects, and test one before you commit to the batch. Get those right, and the rest is repetition.
For a handful of envelopes, Word or Google Docs, and your desk printer will do the job. For a few dozen, mail merge turns an afternoon into a few minutes. And once you are running hundreds or thousands a month, or you want color and logos instead of plain black text, that is the point where a dedicated envelope printer starts paying for itself.
Start with what you have. Print one, check the alignment, adjust, and go. Most envelope printing problems disappear after that first test print. And if you outgrow your desk printer, TCS Digital Solutions carries a focused range of envelope printers built for exactly this kind of work.

Frequently Asked Questions
Can Any Printer Print on Envelopes?
Most modern inkjet and laser printers can handle them, but not all do so well. Look for a manual feed slot or rear feed tray. Printers that only pull from a bottom cassette tend to jam more with envelopes because of the tighter paper path.
What is the Best Font Size for an Envelope Address?
Ten to twelve points works for standard #10 envelopes. Go up to fourteen points on larger flats. Stay with clean sans-serif fonts and skip script or decorative typefaces.
Why Does My Envelope Print Upside Down?
Your loading orientation does not match the setting selected under Printing Options in Word. Change the feed method in the software rather than flipping the envelope, then run one test print.
How Do I Print a Return Address Only?
In Word’s Envelopes dialog, leave the Delivery Address box empty and fill in only the Return Address, then print. This is useful for prepping a batch of envelopes ahead of time.
Can I Print on Colored or Kraft Envelopes?
Yes, though dark stock hides ink. Black text on kraft or light colors reads fine. For dark envelopes, a printer with white ink or a printed label is a better option.
