Breaking down the anatomy of QR codes
QR stands for Quick Response code. It was named this way because the code can be quickly read and decoded by a device such as a smartphone, providing rapid access to digital information encoded within it.
This ability to provide a digital dimension to static materials is one reason QR code marketing is such a widespread strategy in the business industry today.
How does the QR code work? Well, to best understand how this technology works, it is essential to understand its structure. Here's a detailed breakdown of the various components that make up a QR code:
Finder pattern
With the exception of the bottom-right corner in the event of a larger QR code, these are the three sizable squares that are situated at the corners of the QR code. They aid the scanner in determining the QR code's orientation and placement.
Each positioning mark consists of a large square with a smaller square inside it, surrounded by an alternating pattern of black-and-white modules. This helps the scanner determine the QR code's alignment and correct orientation.
Alignment markings
Alignment patterns help the scanner compensate for distortion or skewing, especially in larger QR codes.
These are smaller square patterns located throughout the QR code (not just at the corners). They ensure that the QR code can be read correctly, even if it is slightly distorted or skewed.
Timing pattern
The timing pattern helps the scanner determine the size of the data modules within the QR code.
This pattern consists of alternating black and white modules that run along the rows and columns between the positioning marks. It assists the scanner in gauging the size of the QR code's modules.
Version information
It indicates the version of the QR code, which determines the size and data capacity.
This is found in the QR code if it is Version 7 or higher. It is located near the positioning marks and helps the scanner determine the specific QR code version to process the data accurately.
Format information
The format information section contains information about the QR code’s error correction level and masking pattern.
It is located near the positioning marks and is essential for the scanner to interpret the error correction and data masking used in the QR code correctly.
Data and error correction keys
These are the individual black-and-white squares that encode the actual data in the QR code.
The arrangement and color of these modules represent the encoded data. The scanner reads and decodes the pattern of these modules to retrieve the information.
Quiet zone
This is the empty space surrounding the QR code, which helps the scanner differentiate the code from its background.
The quiet zone should be at least four modules wide. This ensures that the scanner can detect and isolate the QR code.
Does the orientation of the QR code matter?
Yes, the orientation of a QR code does matter, although QR codes are designed to be resilient to various orientations.
Placing them in a standard, upright position can improve scanning ease. Aligning them correctly with the intended scanning direction can also reduce the chance of scanning errors, speeding up the scanning process.
Misaligned QR codes, on the other hand, can affect user experience, particularly if users are required to hold their devices at awkward angles to scan the code.
Proper orientation helps ensure that the QR code is easily accessible and scannable.
Importance of QR code orientation for effective scanning
The orientation of the QR code plays a crucial role in ensuring effective scanning and accurate decoding. Here’s why it matters and how it impacts the scanning process:
Alignment with the scanner's sensor
Although QR codes can be read from a variety of angles, scanning becomes faster and more accurate when the code is properly aligned with the scanner's sensor.
Making sure it is perfectly aligned with the scanning direction, which is usually perpendicular to the sensor, results in error-free QR code reading. Proper orientation helps minimize the risk of misinterpretation or failed scans.
Decoding efficiency
QR codes include error correction methods; however, they work best when the code is scanned in the proper orientation.
A substantially tilted or rotated QR code may challenge the error correction algorithms, making decoding more challenging. The orientation can also impact how well the QR code performs under different lighting conditions.
A well-oriented QR code ensures better contrast and readability, enhancing scanning performance.
User experience for consistency
Proper orientation ensures a smoother user experience. Scanning a QR code that's not oriented correctly can be frustrating for users, leading to potential scanning failures and dissatisfaction.
For printed materials like flyers, posters, or business cards, consistent orientation ensures a predictable experience and that users don’t have to maneuver their devices awkwardly to scan the code.
Types of QR code forms and orientations
When you generate a free QR code, this can be orientated in many ways. These variations and orientations can be chosen based on the specific requirements of the use case, design preferences, and functionality needs.
Keep in mind, however, that their orientation also affects their scanning accuracy and ease. The various types of QR code forms and orientations are broken down as follows:
Standard orientation
The standard orientation is the traditional orientation in which the QR code positioning marks (the large squares or “eyes”) are at the top left, top right, and bottom left corners.
This orientation is the most common and works best for traditional printed materials and digital displays where the QR code is expected to be scanned straight on.
Rotated orientation
The QR code is rotated 90°, 180°, or 270° from its standard position. You can use this in various QR code design where space or layout constraints require the QR code to be placed in a non-standard orientation.
Modern scanners and smartphones can usually read QR codes from different angles, but ensuring the QR code is in a relatively flat orientation helps with readability.
Skewed orientation
Angled placement of the QR code is often due to being printed or displayed on a curved surface.
Skewed orientations occur on promotional materials like banners or on packaging. While most scanners can handle minor skewing due to alignment and correction patterns, excessive skewing can impact scan accuracy.
Distorted orientation
The distortion of the surface on which the QR code is written or the way it is presented influences this orientation.
It is common on curved or irregular surfaces like product packaging and bottles. Distortion can challenge the QR code's readability, but advanced scanners and error correction can help mitigate issues.
Interactive or dynamic orientations
Some QR codes are designed to interact with augmented reality or AR applications or are embedded in interactive displays.
These are oriented to trigger specific AR experiences or interactive features. For example, you can use this type of QR code with an interactive orientation to align with a particular part of a digital experience when scanned.
Circular orientation
Circular QR code orientations are often used for creative or branding purposes. They can fit well into designs where a circular shape is more appropriate or visually appealing, such as logos, badges, or circular promotional items.
The positioning marks, typically large squares at the corners, need to be adapted for a circular format.
They might be represented as circular patterns or adjusted to fit the circular shape while still providing the necessary orientation data for scanners.
Custom shapes and patterns
This involves designing QR codes that deviate from the traditional square format to incorporate various shapes, patterns, or artistic elements.
Customizing the eye, shape, and pattern of the QR code can enhance its visual appeal and make it easier to integrate into unique branding or design themes.
However, this requires careful attention to ensure the QR code remains functional and easily scannable.
The primary challenge with custom QR codes in shapes and patterns is maintaining the QR code’s functionality.
Key components such as positioning marks, data modules, and error correction areas must be preserved and correctly positioned within the custom shape.
Vertical orientation
In this manner, the QR code is rotated 90 degrees from its standard horizontal placement, so its primary axis is vertical.
This means that the QR code is aligned such that the positioning marks are now on the left, right, and bottom sides.
It’s useful when space constraints or design elements require the QR code to be placed in a vertical format (e.g., sidebars, narrow columns).
Top QR code design rules to consider
When designing QR codes, it is essential to follow guidelines related to size, error correction, color contrast, and quiet zones to ensure they are easily scannable and functional.
While customization options exist, such as integrating a logo and creative design elements, the QR code's core structure must remain intact to preserve its readability.
Refer to this list of QR code design rules when you customize a QR code:
Better codes correspond to shorter links
Shortening the URL to the webpage you want visitors to visit will result in a more scannable QR code.
When your audience points their camera at a code, it might not accomplish anything if it isn't scannable enough.
QR codes with fewer pixels are produced by shorter links. As a result, every pixel can be bigger, which facilitates the detection of the entire code by a mobile phone camera.
Make use of black and whites
Black and white or extremely high-contrast color pairings are great when designing QR codes.
Avoid using more than one foreground color and stick to black-on-white in scenarios where optimum scannability is essential.
The background color must also completely surround the code to establish a margin. The clear space surrounding it is just as important as the code's own clarity.
The code must be big enough
A smartphone's camera may not concentrate on QR codes if it is too small.
The distance at which people will be using a code determines its size. The code should be bigger the farther away it is. The code's width should, as a general rule, be at least one-tenth the scanning distance.
Always indicate what the QR code does
A QR code is powerless on its own. It needs additional design components in order to function as a call to action.
Think about writing a description of the code's function next to it. Take "Scan to book now," for example.
Write more than just "Scan me!" as this is useless and doesn't explain what scanning can accomplish.
Don’t include little graphics
Refrain from adding graphics to or overlaying QR codes to make them appear more appealing. These additions complicate code scanning.
When using QR codes, it’s often best to keep them minimal and free of extra graphics or decorations.
This ensures they remain scannable by a wide range of devices and apps. If you need to add branding or visuals, it’s typically a good idea to do so without interfering with the code’s readability.
Why generating a dynamic QR code is better
Based on your unique requirements, you can choose between static and dynamic QR codes—what is a dynamic QR code? If you need to convey information that doesn't need to be changed frequently, a static QR code will do.
A dynamic QR code is better suited for campaigns or circumstances in which content may need to be changed frequently or when tracking data is crucial.
This implies you won't have to edit all of the QR code options on your business cards, brochures, or other legal papers if you wish to modify the URL or landing page.
You can continuously update your content using dynamic QR codes. Simply update the data that has been stored on your dashboard to present the most recent or accurate information.

Best practices for positioning your QR codes
Positioning QR codes effectively is crucial to ensure they are easily scannable and achieve their intended purpose. Here are some best practices to follow:
Strategic placement
Place the QR code in a location that is easily visible and accessible. It should be positioned where users are likely to see it and scan it without difficulty.
Also, make sure to position the QR code where it makes sense within the context. For example, on product packaging, place it where customers can easily scan it while holding or viewing the product.
Positioning on print media
You can place QR codes in prominent positions where people can easily notice and scan them. This could be in the center of a flyer, on the front of a brochure, or in the upper third of a poster.
For printed materials, a QR code must measure a minimum of 1 × 1 inch, or 2.5 x 2.5 cm to ensure it is scannable. Larger sizes are preferred if space allows, especially if the code needs to be scanned from a distance.
Digital and web placement
A large enough QR code is important for easy scanning. On website pages, it should be sufficiently large to be scanned from typical viewing distances.
For digital use, a minimum width of 100 x 100 pixels is recommended, but larger is better for visibility.
Make sure the QR code scales appropriately with different screen sizes and resolutions. It should remain functional and visible on various devices, from desktops to mobile phones.
Design integration
Proper design integration ensures that the QR code not only fits visually within the design but also maintains its scannability and effectiveness.
Ensure that the QR code’s colors harmonize with the overall color palette of the design. You can customize QR codes to match brand colors, but be careful to maintain high contrast between the code and its background.
If your brand colors are blue and white, customize the QR code with these colors while ensuring the code remains readable. For instance, a blue QR code on a white background might work well.
Environmental factors
Minimize glare and reflections that can occur on glossy or shiny surfaces. This is particularly important for QR codes on printed materials or screens.
Use matte finishes or coatings that reduce glare and reflections, and adjust screen brightness and position to avoid direct light sources that could cause glare.
Consider the durability if the QR code is exposed to environmental factors like moisture, abrasion, or sunlight.
Use weather-resistant materials and coatings to protect QR codes from rain, sunlight, and other environmental conditions.
Tips for successful QR code scanning
Successful QR code scanning depends on various factors, including the quality of the QR code, the scanning environment, and user practices.
Here are some useful pointers to guarantee a smooth and successful QR code scanning experience:
Use of smartphones for scanning
Most recent smartphones have camera apps that can scan QR codes; if none, Google Lens QR code scanner is another option. To use them, just open the camera app and aim it at the QR code; a notification or link should appear automatically.
After scanning, verify the content or URL provided by the QR code. Be cautious of QR codes that lead to websites you do not know.
If the QR code is not scanning, try adjusting the distance or angle and ensure good lighting conditions.
Proper alignment and distance
Hold the smartphone at a distance where the QR code is within the camera’s focus range. The distance can change depending on the size of the QR code and the smartphone’s camera capabilities.
When the QR code is small, you need to hold the smartphone closer. For larger codes, a slightly farther distance might be required.
Sometimes, moving the phone closer or farther can help the camera focus better on the QR code.
Using QR code scanning apps
Let’s say your built-in camera does not support QR code scanning. If you need additional features, consider downloading a dedicated QR code scanning app.
Go to your device’s app store, search for a QR code scanning app, and download it.
Most QR code scanning apps automatically recognize and scan the QR code when it is properly aligned. You may see a notification or message indicating that the QR code has been scanned successfully.
If the app isn't working correctly, try restarting it or reinstalling it. Ensure that your smartphone’s operating system and the app are both up-to-date.
