Scan Distance for QR Codes in Real Estate – 40+ Feet!

Qr code's scanning distance and minimum size.

Overview

Discover How You Can Achieve a Long Distance Scan Range

QR Codes offer an amazing opportunity to help generate leads on your listings! When done properly, they allow potential buyers to quickly and easily connect directly with the listing agent. In this article, we’re outlining the best practices and scan distance for QR Codes for Real Estate use.

A lot of people think that QR codes only work at short scanning distances. That’s true, but it doesn’t mean that they won’t work at long distances either. There are two reasons why QR codes work well at long distances. First, the resolution of the camera decreases as the scanning distance increases, but . Second, the camera/scanner processes data differently depending on the distance.

A QR code should be large enough to be easily scanned by a smartphone/mobile device. This typically means that the code should be at least 1.5″ x 1.5″. However, the optimal size will depend on the specific use case and the environment in which the QR code will be used. For example, if the code will be placed on a small business card or flyer, it 1.5″ x 1.5″ – 3.5″ x 3.5″ to ensure that it can be easily scanned. On the other hand, if the code will be placed on a H-Frame or For Sale sign, it should be much larger. Ultimately, the table below breaks down the minimum size for the most common marketing materials for realtors.

General Guidelines for QR Coed Size to Scan Distance Ratio

The minimum size of an QR code is 2cm × 2cm (0.8 × 0.8 inch). There is no standardized QR Code size, but to ensure the majority of current mobile devices are able to read it, a QR code needs to be at least 2cm wide by 2cm long. Although there are some use cases for small QR Codes, it’s recommend Real Estate Agents stick to larger sizes.

QR Codes were originally developed for a 1:10 ratio between the size of the QR Code and the actual message. Keep in mind that does not take a camera’s zoom into account. This means that the optimal scanning distance for a QR Code to be scanned is 10x the height/width of the QR Code, which can be more when zoomed in. 

In other words, if a QR Code is 6 inches wide, it can be easily scanned from sixty inches/5 feet away. That said, we’ll beak down the ideal size by each use case in Real Estate.

Real Estate QR Code: Size to Scan Distance for QR codes Distance Ratio Guide

There are a lot of variables to consider when creating the right sized QR Code for listing/open house signs. The larger the better, but not always necessary. The key variable boils down to the combination of number people will see it and what they’re doing when they see it.

For example, listings with significant foot traffic (i.e. high walk score) can use smaller QR Codes. At the same time, if the listing gets a lot of drive by traffic, you will want to use a larger QR Code to ensure cars can capture the code while driving by.

Additional Guidelines to keep in mind

 When generating a QR code, there are a few best practices to follow to ensure that the code is effective and easy to use:

  • Make the code easy to scan. The QR code should be large enough and have high enough resolution to be easily scanned by a smartphone or QR code reader.
  • Use a reliable QR code generator that has a good reputation and is made for Real Estate like List It Better.
  • Test the code before using it. Before using the code in a real-world setting, test it to make sure it can be easily scanned and that it leads to the intended destination.
  • Use a Dynamic QR code if the information or destination associated with the QR code is likely to change, make sure you use a dynamic QR code that can be easily updated.
  • Keep the design simple and avoid cluttering the design of the QR code with too much text or other elements, as this can make it more difficult to scan.
  • Avoid dark backgrounds because it will make it much more difficult for a mobile device to recognize the code.
  • Make sure you have high quality images with .png and .svg formats. 
  • Keep your branding/QR Code images consistent across all materials.
  • Don’t place anything over, or too close, to any part of the QR Code.

Overall, the key is to create a QR code that is easy to scan and that leads to the intended destination quickly and efficiently.

FAQ Regarding QR Code Sizes and Scan Distance

What is the minimum QR Code size?

The minimum size for a QR Code is 2 x 2 cm (0.8 x 0.8 in), but you may make your QR Codes as big as you need as long as you use high-quality images. For Real Estate Listing Signs, the minimum size recommended is 5 x5 in. Please refer to the table above for other Real Estate use cases.

What is the importance of size for QR codes?

The size of a QR Code is important for successful scanning, regardless of where it is used. The size of the QR Code affects its scannability; if it is not optimized for the correct distance, or too small, it may lead to fewer scans.

What is the suggested size for QR codes on a business card?

The ideal QR code size for business cards is roughly 1.5 x 1.5 in, but it is not recommended to make the QR Code smaller than 1 x 1 in. Any smaller and it might not be scannable, or noticed.

Note: Assuming the standard business card size of 3.5 x 2 in.

What is the largest size possible for a QR Code?

In theory, QR Codes can be as big as you’d like them to be. There is no maximum QR Code size.The only limitation in the maximum size of a QR Code is based on the quality of the image file. A SVG (Scalable Vector Graphics) file type allows unlimited scale, as the graphics and resolution are independent and can be scaled up or down without losing quality because they are based on mathematical equations and geometric shapes rather than pixels.

List It Better gives you the option to download PNG and SVG files. The PNG file should be large enough for most use cases in Real Estate, which you can scale up to 30 x 30 in.

How large does a QR Code need to be?

Please refer to the table above for best practices for QR Code sizes for different use cases in Real Estate.

What are QR Code Printing Guidelines & Best Practices?

Minimum size: The minimum size for a QR code is 0.8 x 0.8 in (2 x 2 cm). Anything smaller than this may be difficult to scan, particularly if the QR code is printed on a small object or in a location that is not easily accessible.
Resolution: When printing QR codes, it is important to use a high enough resolution to ensure that the code can be easily scanned. A minimum resolution of 300 dpi is recommended to ensure that the QR code is clear and crisp.
Aspect ratio: The aspect ratio of the QR code should be maintained to ensure that it can be easily scanned. The ideal aspect ratio is 1:1, meaning that the QR code is square.
Quiet zone: The quiet zone is the space around the QR code that should be left blank to ensure that the code can be easily scanned. The minimum size for the quiet zone is four modules, or the size of four black and white squares within the QR code.
Contrast: The QR code should be printed in a high-contrast color scheme to ensure that it can be easily scanned. Black on white or white on black is the most common color combination, but other high-contrast color combinations can also be used.

Final Thoughts: Scan distance for QR Codes in Real Estate

When creating QR Codes for your materials, common sense is the best guide. The farther away the code scanner will be, the larger the code should be. The sizes above are recommendations, and should be used as a guideline. If you need to adjust the size of the code to fit your templates, than you should. No matter what you should always test your codes before printing/sending to production!
