Complete A4 Address Label Size Guide

Choosing the right A4 address label depends on the size of the envelope, parcel or package, how much address information you need to print, and how many labels you want on each sheet.

A4 address labels are available in many layouts. The number of labels on each sheet is usually described as UP.

For example:

• 8UP = 8 labels on one A4 sheet
• 14UP = 14 labels on one A4 sheet
• 21UP = 21 labels on one A4 sheet
• 30UP = 30 labels on one A4 sheet

Generally:

Lower UP = larger labels
Higher UP = smaller labels

Which A4 Address Label Size Should I Choose?

Use this as a simple starting point:

The exact size you need depends on the amount of information you are printing and the available space on the package.

4UP–8UP: Large Address Labels

Larger labels provide plenty of room for clear printing.

They are suitable for:

• Large cartons
• Large parcels
• Warehouse dispatch
• Mailing satchels
• Business-to-business deliveries
• Packages requiring additional information

They can provide space for:

• Recipient name
• Company name
• Full address
• Phone number
• Order number
• Delivery instructions
• Company logo

For a normal envelope, these sizes may be larger than necessary.

9UP–16UP: Medium Address Labels

Medium A4 labels are highly versatile.

They work well for:

• Mailing satchels
• Medium parcels
• Large envelopes
• Small cartons
• Business correspondence
• Customer order fulfilment

Common layouts include:

9UP, 10UP, 12UP, 14UP and 16UP

These sizes give you a good balance between printing space and the number of labels per sheet.

18UP–24UP: Standard Mailing Labels

This range is useful for everyday address printing.

Best for:

• Business envelopes
• Customer invoices
• Statements
• Letters
• Marketing mail
• Membership mail
• General office correspondence

Common layouts include:

18UP, 20UP, 21UP and 24UP

They normally provide enough room for a standard address such as:

Customer Name
Company Name
Street Address
Suburb VIC 3000

27UP–36UP: Small Address Labels

Smaller A4 address labels are useful when the amount of information is limited.

Best for:

• Small envelopes
• Compact packages
• Small mailers
• Short postal addresses
• Return addresses
• Internal office mail

Common layouts include:

27UP, 30UP, 33UP and 36UP

These layouts provide more labels per sheet and can be economical for high-volume mailing.

Make sure your font remains clear and easy to read.

30UP and Above: Return Address Labels

Return address labels usually need much less space than the main recipient address.

Suitable layouts can include:

30UP, 33UP, 36UP, 40UP, 45UP, 48UP, 55UP, 65UP and 84UP

They are useful for:

• Sender addresses
• Company return addresses
• Reply mail
• Small envelopes
• Business correspondence
• Company identification

A return address may only need:

Blumax
Melbourne VIC
Australia

Because less information is required, smaller labels are usually suitable.

Address Label vs Shipping Label

An address label and a shipping label are not always the same thing.

Address Label

An address label normally contains:

• Recipient name
• Company name
• Street address
• Suburb
• State
• Postcode

Shipping Label

A complete shipping label may also contain:

• Courier details
• Tracking number
• Barcode
• Service type
• Sender information
• Sorting information
• Parcel reference

Because shipping labels contain more information, they usually require more space.

Best A4 Address Labels for Envelopes

Large Envelopes

Good starting choices:

10UP, 12UP, 14UP or 16UP

Standard Business Envelopes

Consider:

14UP, 16UP, 18UP, 21UP or 24UP

Small Envelopes

Consider:

21UP, 24UP, 27UP or 30UP

Return Addresses

Consider:

30UP and above

Always compare the actual label dimensions with your envelope before ordering.

Best A4 Address Labels for Parcels

For small parcels, consider:

10UP–14UP

For medium parcels, consider:

6UP–12UP

For large cartons, consider:

4UP–8UP

If the label also contains a courier barcode or tracking information, choose a larger format.

How Much Information Needs to Fit?

The number of address lines matters.

Short Address

Example:

John Smith
Richmond VIC 3121

A smaller label may be sufficient.

Standard Address

Example:

John Smith
ABC Company
20 Example Street
Richmond VIC 3121

A medium label will normally work better.

Detailed Business Address

Example:

Attention: John Smith
ABC Company Pty Ltd
Unit 12, 20 Example Street
Richmond VIC 3121
Australia

Choose a larger label so the text remains easy to read.

Do You Need Space for a Logo?

If you want to include your company logo, allow additional room.

You may also want to print:

• Business name
• Phone number
• Website
• Customer number
• Order reference

A slightly larger label often produces a cleaner result.

Landscape or Portrait?

For most postal addresses, a wider rectangular label works well because addresses are normally printed across several horizontal lines.

For example:

Company Name
123 Example Street
Melbourne VIC 3000

A wider label can often use the available space more efficiently.

Font Size Matters

Do not choose a smaller label only because it gives you more labels per sheet.

A label is only useful if the address remains easy to read.

The important balance is:

More labels per sheet + clear readable printing

If the address looks crowded, choose a larger layout.

Can Address Labels Also Be Used for Products?

Yes, many rectangular A4 labels can have several applications.

Depending on the size, the same label might work as:

• Address label
• Product label
• Packaging label
• Barcode label
• Identification label
