Correct barcode and QR code placement is essential for fast and reliable scanning. This guide explains the key factors to consider, including code size, quiet zones, contrast, surface selection, print quality, and placement within the label design.

How Should Barcodes and QR Codes Be Placed in Label Design?

The use of barcodes and QR codes on product labels has become standard in many industries. In retail, logistics, e-commerce, food, cosmetics, and industrial applications, barcodes are widely used for product identification, stock management, and tracking, while QR codes are often used to direct customers to websites, product information, campaign pages, manuals, or other digital content.

However, simply adding a barcode or QR code to a label is not enough.

If the code is too small, placed incorrectly, printed with poor contrast, or positioned on a difficult surface, it may become hard or impossible to scan.

For this reason, barcode and QR code placement in label design should be planned carefully.

Why Is Correct Barcode and QR Code Placement Important?

The main purpose of barcodes and QR codes is to be read quickly and accurately.

Incorrect placement can cause:

Barcode scanners to fail
QR codes to become difficult to scan with a smartphone
Checkout processes to slow down
Warehouse and logistics errors
Product tracking problems
Poor customer experience

For this reason, code placement is not only a design decision. It is also an operational requirement.

Where Should a Barcode Be Placed on a Label?

A barcode should be placed on a surface that is as flat and readable as possible.

Avoid placing barcodes on areas of packaging that are:

Highly curved
Folded
Easily crushed
Seamed
Too close to the edge

On bottles, jars, and cylindrical packaging, placing a barcode on an excessively curved area can make scanning more difficult.

Whenever possible, the barcode should be positioned in a flat and easily accessible section of the label.

Leave Enough Clear Space Around the Barcode

One of the most important parts of barcode design is the clear space around the code.

Avoid placing the following immediately next to the barcode:

Text
Logos
Borders
Graphics
Patterns
Strong color transitions

The barcode requires sufficient clear space around it so that scanners can distinguish the code from surrounding design elements.

This space is often referred to as the quiet zone.

Do Not Make the Barcode Too Small

Reducing the barcode too much to save label space is a common mistake.

As the barcode becomes smaller, the bars become closer together and print tolerance becomes more critical.

This can make the barcode difficult to read, especially with lower-resolution printing.

Barcode dimensions should take into account:

Barcode type
Printing method
Label size
Scanner type
Scanning distance

Even on compact packaging, barcode readability should take priority over visual design.

What Should Barcode Color Contrast Be Like?

High contrast is recommended for barcodes.

The safest and most common combination is:

Dark barcode + light background

For example, a black barcode on a white background generally provides strong readability.

Low-contrast combinations can reduce scanner performance.

Special care should be taken with:

Light gray barcodes on light backgrounds
Barcodes placed over complex patterns
Low-contrast barcodes on metallic surfaces
Barcodes on transparent labels without background control

The final printed contrast should always be considered, not just how the design looks on screen.

Can Barcodes Be Used on Transparent Labels?

Yes.

Barcodes can be printed on transparent labels, but the background behind the code becomes especially important.

If a transparent label is applied to packaging of different colors, barcode contrast may change significantly.

For example, a black barcode applied over a dark bottle may become difficult to scan.

In these situations, using a white underprint beneath the barcode area may be beneficial.

This helps create a more stable and higher-contrast background for the barcode.

Where Should a QR Code Be Placed on a Label?

Like a barcode, a QR code should ideally be positioned on a flat surface.

Avoid placing the QR code:

On fold lines
Too close to label edges
On highly curved surfaces
Near cap joints
Over packaging seams

The QR code should be placed where customers can comfortably point a smartphone camera at it.

Accessibility is especially important for customer-facing QR codes.

Should There Be Clear Space Around a QR Code?

Yes.

A QR code also needs a clean area around its outer edges.

Avoid placing the following too close to the code:

Text
Logos
Frames
Graphics
Photos

Leaving enough clear space helps smartphone cameras identify the boundaries of the QR code more easily.

What Size Should a QR Code Be?

QR code size should be determined according to its actual use.

If the QR code is too small, a smartphone camera may have difficulty detecting it.

The appropriate size depends on:

Amount of data encoded
Print resolution
Scanning distance
Label size
Packaging surface

For example, a QR code on a small cosmetic label does not need to be the same size as one printed on a large shipping box.

Testing the code at its actual printed size before production is recommended.

Can a Logo Be Added Inside a QR Code?

Yes, a logo can be placed inside a QR code for branding purposes.

However, the logo should not cover too much of the QR code pattern.

An oversized logo may reduce scan reliability.

If a logo is added inside the QR code:

Keep the logo area limited
Avoid covering critical code areas
Maintain strong contrast
Test the final printed version on real devices

Visual design should never compromise scan performance.

Barcodes and QR Codes Should Not Be Placed Too Close Together

If both a barcode and QR code are used on the same label, leaving enough distance between them is helpful.

Placing the two codes too close can:

Make the design look crowded
Increase the chance of scanning the wrong code
Reduce the required quiet zones
Create unnecessary visual confusion

Whenever possible, place the barcode and QR code in separate sections of the label.

For example, the barcode can be positioned near the bottom while the QR code appears on the side or back panel.

Does Barcode Orientation Matter?

Yes, especially in automated scanning systems.

If fixed barcode scanners are used on a production line or in a logistics system, the barcode orientation should be compatible with the scanning setup.

Handheld scanners are generally more flexible, but automatic systems may depend heavily on position and direction.

For this reason, barcode orientation should be checked before mass production.

Do Not Place Codes Too Close to the Label Edge

Positioning a barcode or QR code too close to the cutting line creates unnecessary risk.

Small cutting tolerances may occur during label production.

If the code is too close to the edge:

Part of the code may be cut off
Quiet zones may become too small
Scan performance may decrease
The design may look unbalanced

Barcodes and QR codes should therefore be positioned at a safe distance from the cutting line.

Print Quality Affects Code Readability

Even with correct design, poor print quality can prevent a barcode or QR code from being scanned.

During printing:

Barcode lines may merge
Thin lines may disappear
QR code modules may become distorted
Ink may spread
Fine details may lose sharpness

For this reason, print quality is especially important on labels containing machine-readable codes.

Barcodes and QR codes should preferably be used from vector files or sufficiently high-resolution artwork.

Avoid Using Screenshot Images of Barcodes

Using a low-resolution screenshot of a barcode or QR code can cause serious print problems.

A code may appear sharp on a screen but become pixelated when printed.

Whenever possible, use:

Vector barcode files
High-resolution QR codes
Print-ready PDF or SVG files

This helps preserve the sharpness of bars and code modules.

Does Label Material Affect Barcode Readability?

Yes.

Label material can affect both print appearance and scan performance.

Coated Paper Labels

Coated paper labels generally provide clean barcode and QR code printing and are suitable for many standard applications.

White PP Labels

White PP labels offer durability while also supporting clear machine-readable code printing when produced correctly.

Clear PP Labels

With transparent labels, the background color must be taken into account.

A white underprint may be needed in the code area.

Metallized Labels

Reflective or metallic surfaces may create scanning problems.

It can be beneficial to place the barcode or QR code in a more matte and higher-contrast area.

Should Barcodes and QR Codes Be Tested Before Printing?

Absolutely.

Before mass production, both barcode and QR code performance should be tested at the actual print size.

Tests can be carried out using:

Smartphone cameras
Barcode scanners
Handheld terminals
POS systems

This makes it possible to identify readability problems before large quantities are printed.

Dynamic QR Code or Static QR Code?

QR codes can be either static or dynamic depending on the intended use.

Static QR Code

A static QR code contains information that does not change after creation.

For example, it may direct users to a fixed website address.

Dynamic QR Code

With a dynamic QR code, the destination link or content can be changed later.

This can be useful for:

Campaigns
Product promotions
User manuals
Menus and catalogs
Marketing activities

If the label will remain in use for a long time but the digital destination may change, a dynamic QR code can be worth considering.

What Should a QR Code Offer the User?

A QR code should not be added to a label only because it looks modern.

It should provide useful information or an action for the user.

A QR code can direct customers to:

Product details
Instructions for use
Certification information
Campaign pages
Video content
Social media accounts
Contact information
Product verification pages

Adding a short call-to-action near the QR code can also improve usability.

For example:

“Scan for more information”

“Scan the QR code to view product details”

can help guide the user.

Common Barcode and QR Code Design Mistakes

Some of the most common mistakes include:

Making the code too small
Leaving insufficient clear space
Using low contrast
Placing the code too close to the label edge
Applying the code to a highly curved surface
Using low-resolution artwork
Placing graphics or text over the code
Ignoring the background on transparent labels
Failing to test the code after printing

Avoiding these mistakes significantly improves scanning reliability.
