Hand-addressing a stack of envelopes is slow, and messy handwriting can delay delivery. A Dymo LabelWriter turns the same job into a few minutes of printing. Dymo address labels come in four main part numbers, though, and picking the wrong one leaves you with cramped text or labels that don’t fit the envelope. This guide covers the address labels themselves: which one fits which mailing, how to print a whole list at once, and how to make every envelope look professional.

Dymo 30252: The Everyday Address Label
The Dymo 30252 is the label most offices reach for first. At 1-1/8” x 3-1/2”, it holds a clean three-line address and fits neatly on standard #10 envelopes, greeting cards and padded mailers. Our compatible Dymo 30252 address labels come 350 to a roll, so you can get through a large mailing without stopping to change rolls.
Some small businesses also use the 30252 as a shipping label for light envelopes. For boxes and heavier parcels, a larger label is the better choice: see our shipping labels collection for sizes such as the 30256 and 4” x 6”.
Dymo 30320: Same Size, Smaller Roll
The Dymo 30320 has the same 1-1/8” x 3-1/2” dimensions as the 30252, but our version holds 260 labels per roll. It suits home offices, churches and clubs that mail regularly but not in high volume. Because the template is identical, you can switch between the two without redesigning anything. Order Dymo 30320 address labels if you prefer a smaller roll.
Dymo 30321: The Large Address Label
When an address runs to four or five lines, such as a company name, attention line, suite number and city, a standard label gets crowded. The Dymo 30321 adds height at 1-4/10” x 3-1/2”, which leaves room for every line plus a small logo. Our Dymo 30321 labels are the go-to option for business correspondence and international addresses.
Dymo 30330: Return Address Labels
The Dymo 30330 is a compact 3/4” x 2” label made for the back flap or top-left corner of an envelope. Print a few hundred at once and keep them by your mail tray. Our Dymo 30330 return address labels hold 500 per roll, which lasts most households and small offices a long time.
How to Print a Mailing List in One Go
You don’t need to type addresses one by one. Dymo Connect for Desktop can pull them from a spreadsheet:
1. Prepare your list in Excel or as a CSV file, with separate columns for name, street, city, state and ZIP code.
2. Open Dymo Connect and select your label, for example 30252.
3. Add an address object to the label layout.
4. Import your data and map each spreadsheet column to the matching line on the label.
5. Preview and test by printing one label to check alignment, then print the full batch.
This works the same way on 30320 and 30321 labels, so you can reuse your spreadsheet for future mailings.
Tips for Professional-Looking Address Labels
• Use a clear font. A simple sans-serif typeface at 10 to 12 points is easy for people and sorting machines to read.
• Follow postal formatting. USPS addressing guidelines favor uppercase letters and minimal punctuation for machine readability.
• Leave a margin. Keep text slightly away from the edges so nothing gets cut off.
• Apply to a clean, flat surface. Press firmly from the center outward to avoid bubbles and peeling corners.
Using a Brother Printer Instead?
If your office runs a Brother QL printer, the same principles apply with a different roll. Explore our Brother address labels collection for compatible options.
Conclusion
Choosing the right Dymo address labels comes down to how much you mail and how much you need to fit on each label. Use the 30252 for everyday mail, the 30320 for smaller runs, the 30321 for longer addresses and the 30330 for return addresses.
