THE QUICK ANSWER
There is no single address label size for every job
Start with the space on your envelope or parcel and the details you need to print. Compact sender details and a long recipient address can need different amounts of room.

MATCH THE MAILING TASK
Choose for the details you need to fit
On mobile, swipe to compare the three uses.
Envelope address labels
Try the complete address on a paper mock-up. Compare a compact mailing format such as 63.5 × 38.1mm with a wider option such as 99.1 × 38.1mm when lines are longer.
Parcel address labels
Measure the flat area of the packaging and keep the label away from edges, openings and seams. For a carrier-generated shipping label, use its specified layout and scale.
Swipe through the three uses
Blank and printed products may list dimensions differently. For example, the compact blank layout is 38.1 × 21.2mm, while our personalised return-label product lists 38 × 21mm. Match the specific product and template rather than assuming they are identical.
LARGER PARCELS, CARTONS & PALLETS
Half-sheet and full-sheet identification labels
When you need more room for dispatch references, readable text or a supplied logistics layout, compare these larger formats. Match the label to the system’s required dimensions and test adhesion on the actual packaging.
199.6 × 143.5mm
Half-sheet format
A large area for parcel addresses, box identification or dispatch information when the layout fits.
199.6 × 289.1mm
Large single-label format
One large label with a border around the sheet, for carton, pallet or other dispatch identification.
210 × 297mm
Full A4 label
One full-sheet label for larger identification layouts. Check the printer’s printable area; a full A4 label does not mean borderless printing.
Swipe to compare larger formats
A large label is not automatically suitable for every pallet or carrier system. Check required dimensions, barcode scale and clear spaces. Choose the material and adhesive for the carton, wrapping or other surface and the conditions it will face. Keep the complete label and its codes on a suitable flat area.
CHECK BEFORE ORDERING
Test the size with your longest address
Choose readable text and a comfortable fit on the packaging. Reducing the text to fit the smallest sticker can make the result difficult to read.
Ask for size advice- Measure the usable areaAllow for the envelope layout, closures, seams and the flat surface of a parcel.
- Set up a paper mock-upCreate a rectangle at the intended label dimensions and print it at actual size.
- Fit the full addressInclude the longest name, business details and all required address lines. Leave space inside the cut edge.
- Check on the packagingPlace the mock-up where the label will sit. Make sure it fits flat and the details remain clear.
SHEET COUNTS & PRINT LAYOUTS
Check the label count and the template
Work out the number of labels
Multiply sheets by labels per sheet. For example, 10 sheets × 21 labels = 210 labels. At 14 per sheet, 10 sheets contains 140 labels.
Use the layout count for the product you choose. Consider allowing spare sheets for print tests and setup.
Match the full layout
The number per sheet is only one part of a template. Width, height, gaps and margins also need to match. Use A4 and 100% or Actual Size with scaling turned off.

YOUR QUESTIONS ANSWERED
Address label size FAQs
What size address label should I use for an envelope?
Choose a label that fits the usable area of the envelope and leaves enough room for the complete address in readable text. Our blank options include 63.5 × 38.1mm at 21 per A4 sheet and 99.1 × 38.1mm at 14 per sheet. These are options to compare, rather than a universal size requirement.
What size label should I use for a parcel?
For a simple recipient address, choose enough space for the complete details without wrapping over an edge or seam. For a carrier-generated shipping label, follow the size and format supplied by the carrier or booking system. Do not shrink or crop the output to fit an unrelated label size.
Which labels are suitable for compact return address details?
Our personalised return address product lists 38 × 21mm, 45 × 25mm and 63.5 × 38.1mm options. Choose one that fits your sender details clearly. Check the product selector because the dimensions listed for blank and printed ranges may differ.
What does labels per sheet mean?
It is the number of individual labels on one A4 sheet. For example, 21 labels per sheet means each sheet contains 21 labels. Multiply the number of sheets by the labels per sheet to calculate the total label count.
Are all 21-per-sheet labels the same?
No. The label count alone does not identify the exact dimensions, margins or gaps. Match the full layout to your product and template before printing.
Are 38 × 21mm and 38.1 × 21.2mm the same size?
The dimensions are not identical. Our personalised return-address range lists a 38 × 21mm option, while our blank range includes 38.1 × 21.2mm. Use the exact dimensions and template specified for the product you order rather than assuming the layouts match.
Can I use a larger label for a long business address?
Yes. A wider or taller label can provide room for a business name, extra address lines or other details. Try the longest address at actual size and keep the text clear of the label edge. Choose the layout that fits the content and packaging.
Where can I get a matching address label template?
Use our label templates page and match the exact width, height, label count, gaps and margins. Select A4 and print at 100% or Actual Size with scaling off. Check alignment on plain paper first.
Do you offer larger labels for parcels, cartons or pallets?
Yes. Our larger A4 formats include 199.6 × 143.5mm at two per sheet, 199.6 × 289.1mm at one per sheet and 210 × 297mm at one per sheet. Match the required dispatch or logistics layout, printer, material and adhesive to the application. Full-sheet label dimensions do not guarantee borderless printing.
Can I order a size that is not listed?
Explore our made-to-order label range or request a quote with the finished dimensions, quantity, material and printer details. For printed labels, include your artwork or the information you need to fit.
