The best QR code size for printing is between 2 and 5 centimeters (approximately 0.8 and 2 inches) for flawless readability. It refers to QR codes placed on brochures, flyers, product packaging, and so on. 

Considering your code’s viewing and scanning distance is also essential. When choosing the size for your printed QR code, pay attention to print resolution. This way, you will maintain clarity and prevent the potential loss of image quality. Also, ensure the design of your card, flyer, brochure, etc., matches the chosen QR code’s size. The white space (“quiet zone”) around your code should be at least 15% of its size to maximize its scannability.

Using QR codes in printed advertising is highly beneficial for modern businesses. In the US alone, nearly 89 million smartphone users scanned a QR code on their smartphones in 2022, which is 26% more than in 2020 (Statista, 2023). With the right design and perfect size for scanning, your code will bridge your physical ads and digital content, bringing more customers to your website, social media pages, or else. 

Ideal QR Code Size for Business Cards

The ideal QR code size for a business card is 2 to 5 centimeters (0.8 to 2 inches). It balances the limited space on a physical business card and the optimal code’s scannability. 

A 2×2 cm QR code fits business cards since it doesn’t dominate the space yet remains noticeable and readable. Moreover, with a robust QR code generator like MyQRCode, you can customize your code’s style and tailor it to your card’s design. In particular, changing the color palette, shape, frame, and pattern of your QR code is possible.

It’s worth noting that in today’s digital world, companies strive to provide more interactive and engaging experiences to the audience. People throw away nearly 88% of business cards, as per CreditDonkey, 2022.

Therefore, ensuring that all the design elements fit all types of screens has become a rule of thumb for modern businesses. A 150×150-pixel QR code is convenient to scan via any device and platform, resulting in better user experience and increased satisfaction.

Best QR Code Size for Restaurant Menu

The best QR code size for a restaurant menu is approximately 3×3 centimeters (1.2×1.2 inches). This way, your code will be clearly visible on the menu without occupying too much space. 

Please note that QR codes on restaurant menus are often slightly larger than on flyers, brochures, and product packaging. Thus, customers can instantly identify the code and quickly access the encoded information. At the same time, the space on a menu is usually limited. A QR code that is too big may create visual clutter and distract attention from the primary content. So, it’s worth choosing the size that will keep the right balance, depending on your menu’s size and design specifics.

When implemented correctly, a QR code for a restaurant menu enhances customer experience and streamlines the ordering process. Visitors spend 15 to 20% less time making orders via QR codes than with paper menus (New York Post, 2022). 

Proper QR Code Size for YouTube and Other Videos

The proper QR code size for YouTube and other video content is about 4×4 centimeters (1.6×1.6 inches), which is nearly 113×113 pixels. Such a code is easy to scan, remaining visible on various screens without distracting viewers from the visuals displayed.

Please remember to communicate the role and value of a QR code clearly and convincingly. Explain where the code takes (for instance, to a web page, additional content, video-related promotional offer, etc.) The code’s size and design should meet your video’s specifics and remain on the screen for sufficient time, enabling viewers to notice and scan it. 

Video remains one of the most effective marketing tools. Over 91% of businesses use YouTube and other video-sharing services to attract more customers (Wizowl, 2023). Combining it with a QR code is a result-driven way to retain viewers and drive traffic to your website, business page, or social media.

Optimal Size for QR Codes Scanned at Medium-Distance Proximity

The optimal size for a QR code scanned at medium-distance proximity is between 6 and 10 centimeters (3 to 4 inches). This size suits retail materials, presentations, and TV commercials.

Appropriate QR code size for static city billboards
The appropriate QR code size for static city billboards is 12 to 15 centimeters (4.7 to 5.9 inches) or beyond, depending on the billboard’s size and location. The general guideline here is to rely on the scanning distance. Simply put, the farther your billboard is from people on the street, the larger your code should be. Most importantly, make sure people can easily scan the code while walking or driving nearby.

Providing high contrast between the code and background is also essential to facilitate scanning. It’s a good idea to test the code and verify its scannability from different angles before placing it on the static city billboard.

Correct QR code size for digital billboards
The correct QR code size for a digital billboard is approximately 10×10 centimeters (3.9×3.9 inches). Digital billboards are dynamic and have shorter viewing times. A slightly smaller size implemented in this advertisement type contributes to rapid comprehension and scanning.

Also, please note that the QR code on digital billboards is part of a concise message delivered to potential customers. With that in mind, verify whether your code’s size, design, and location fit this idea well.

Recommended QR code size for transit advertising billboards
The recommended QR code size for transit advertising billboards (for example, placed on buses or train stations) is 8 to 10 centimeters (3.1 to 4 inches). Considering the limited time available for scanning, this size ensures visibility for commuters.

Please remember that this type of advertising targets a moving and busy audience. So, ensuring the code’s maximized visibility and good contrast with the background is crucial.

Factors that Influence QR Code Size

The factors that most critically influence the ideal QR code size include the code’s shape and error correction. Let’s take a closer look at each of them.

How the Shape of a QR Code Influences Its Size

The QR code’s shape directly impacts its size in terms of functionality, scanning distance, and visual integration. Here’s how the shape of different QR codes – square, rectangular, and circle – impacts their appropriate sizes.

• Square QR codes. Square is the most common shape for QR codes. They are the most versatile in scanning, allowing for any size, depending on your individual needs. For instance, a small square QR code is perfect for close-range scenarios. It suits business cards, product packaging, and restaurant menus. In contrast, large square QR codes are ideal for scanning from a distance. You can use them for store entrances, city billboards, and more.
• Rectangular QR codes. This QR code shape is less widespread than square ones. The most famous example of its implementation is rMQR (Rectangular Micro QR Code). Such codes are suitable for specific use cases when the code needs to fit small elongated objects, like product labels on packaging. Also, the scanning angle and distance impact such codes more. 
• Circle QR codes. The circle shape is rather uncommon for QR codes. Circle codes shouldn’t be too large since the square shape doesn’t maximize scannability from any angle and distance. Consider using a circle QR code for unique print and marketing materials to highlight distinct designs and the brand’s creativity.

The shape of a QR code can be different depending on your goals and implementation scenarios. However, the square shape is the most flexible solution for various QR code sizes and scanning distances.

The Influence of Error Correction on QR Code Size

The QR code’s error correction level influences its size since this feature is critical regarding the code’s data capacity. Error correction makes QR codes functional even if their parts are damaged or blurred. Larger codes allow for a higher error correction level. In turn, more compact ones support a lower level of correction.

What Is the Best Size of QR Code with the Highest Level of Error Correction?
The larger size (5 centimeters or 10 inches and beyond) is best for a QR code with the highest correction level, like Level H. Such codes are more damage-resistant due to printing imperfections, wear, or weather conditions. This error correction level requires a bigger QR code size. Thus, you can adopt sufficient space for greater data redundancy. Large codes with higher error correction are perfect for enhanced reliability and endurance.

What Is the Best Size of QR Code with the Lowest Level of Error Correction?
The best size for QR codes with the lowest error correction level, such as Level L, is more compact (approximately 2 centimeters or 0.8 inches). Lower error correction levels and smaller sizes are suitable when your code isn’t likely to experience any damage, wear, or distortion. At the same, the basic error correction capabilities will still be in place. Such codes are perfect for compact print materials and other objects, like business cards and product labels.

Best Size for Different Types of Two-Dimensional Barcodes

The best size for different two-dimensional barcode types, such as mQR, Aztec code, Data Matrix code, etc., varies from 1×1 centimeters (0.4×0.4 inches) to 5×5 centimeters (2×2 inches). The most appropriate dimensions depend on the particular barcode type’s specifics, including available space, data capacity, and implementation requirements.

Here are the optimal sizes for the most widespread two-dimensional barcode types, apart from standard QR codes:

• mQR (Micro QR Code). The best micro QR code size is around 1×1 centimeters (0.4×0.4 inches). It’s compact enough to fit the limited space you can place your mQR on (for instance, small product labels).
• Aztec code. The most suitable size for an Aztec code is nearly 2×2 centimeters (0.8×0.8 inches). It balances optimal readability and space efficiency, ensuring versatility for different uses, such as airline tickets or car registration documents.
• Data matrix code. The ideal size for a data matrix code is around 2×2 centimeters (0.8×0.8 inches). Considering these dimensions accommodate critical data encoding, they suit various use cases like manufacturing and logistics.
• PDF-417 barcode. The best size for PDF-417 barcodes is approximately 4×2 centimeters. While remaining perfectly readable, such a code fits identification cards, boarding passes, and other uses.
• MaxiCode. The perfect size for MaxiCode is around 5×5 centimeters (2×2 inches). This larger size is optimal for capturing the intricate hexagonal pattern, which suits shipping labels in logistics.
• rMQR (Rectangular Micro QR Code). The appropriate size for rMQR codes is around 1.5×1 centimeters (0.6×0.4 inches). This size fits narrow spaces required for equipment inventory in medical and pharmaceutical fields.

Please note that alternative types of two-dimensional barcodes are less versatile than QR codes. In particular, they usually suit specific industries and use cases. Meanwhile, QR codes have many possible implementations, from small printing materials to giant city billboards.

What Is the Smallest QR Code Size that Is Still Scannable?

The smallest QR code size that is still scannable is approximately 1×1 centimeters (0.4×0.4 inches). However, such QR codes may not be readable via all types of devices and scanning applications. Therefore, if your goal is to maximize your code’s accessibility, it’s better to stick to the optimal QR code size minimum for printing, which is 2×2 centimeters (0.8×0.8 inches).

As mentioned, the minimal QR code size depends on the 10:1 scanning size to distance ratio. Therefore, if your QR code is 2×2 centimeters (0.8×0.8 inches), the ideal scanning distance is 20 centimeters (8 inches). 

What Is the Largest QR Code Size that Can Be Scanned?

The ideal size for large QR codes that can be scanned from a distance is 10 to 15 centimeters (4 to 6 inches). However, there are no specific limitations for the maximum QR code size. Even bigger codes are scannable via mobile devices. 

In fact, the largest QR code ever made, created from crops in Indiana, USA, was placed on the 159,918 square meters (1,721,344 square feet) area (Yuengling, 2022). However, such a giant QR code can be scanned only from the air. This size suits promotional events aiming to set world records and generate buzz in social media.

Finding the Right Size for QR Code

To find the right size for your QR code, please consider the following recommendations and best practices:

• Consider the amount of data. Determine how much information you want to encode. The more data you need, the larger your code should be. When striving to fit a QR code in a limited space, seek the balance between the amount of data and the preferred code size.
• Evaluate the optimal scanning distance. If your QR code should be scannable from a distance, make it big enough to remain readable. In contrast, QR codes printed on brochures or product packaging can be smaller due to the close-range scanning.
• Balance visibility and design specifics. Make sure your QR code is easy to copy and scan. At the same time, ensure it doesn’t negatively impact the aesthetics of the medium it’s placed on.
• Test your code in real conditions. Testing your code’s readability and effectiveness before finalizing its size is vital. This way, you will learn whether your code is scannable from different angles, with various lighting conditions, and via all popular devices and scanning apps. If you spot any potential challenges, you can change the code’s size without money and reputational losses.  
• Use a QR code size calculator. Turn to a convenient tool to find the proper dimensions for your QR code. When you input the desired data and run such a calculator, it will offer you the optimal size, taking into account your future code’s specifics.
