Aspect ratio calculator billboard1/8/2023 Currently, the minimum configuration is 11 x 11 modules and the maximum is 171 x 171 modules respectively. However, in terms of modules (and not the final size which can be altered by stretching and rescaling), there are the minimum and maximum configurations. This ensures that they occupy the least possible space while also being scannable for users. But, again, if you want your QR Codes to be as small as possible, we recommend a 1 cm x 1 cm size. There is no maximum or minimum possible QR Code size. In theory, QR Codes can be as big/small as you’d like them to be. What is the maximum possible size of a QR Code? In addition, they have to be big enough to showcase any custom visual elements that may attract people to scan. We recommended that you choose your QR Code dimensions well above the smallest possible size so that they can be easily scanned by smartphone cameras. In pixels, this QR Code size will approximately be a resolution of 38 x 38 px. While there is no fixed minimum size for QR Codes, 1 cm x 1 cm is a good baseline for most close proximity use cases. What is the minimum size required for a QR Code? This is the maximum number of modules that can be used in QR Codes today.ĭepending on the amount of data to be encoded and the character type (alphanumeric, binary, Kanji, etc) more modules are required, and therefore a bigger size. The latest QR Code type is Version 40 with a 177 x 177 configuration-a total of 31,329 modules. With each new version, there has been an addition of 4 modules horizontally and vertically. Version 2 comprised a 25 x 25 module configuration, Version 3 was 29 x 29 modules, and Version 4, 33 x 33 modules. The earliest version (Version 1) of a QR Code comprised a 21 x 21 module configuration, i.e, 21 modules along two directions. Each of these squares, which can be in other contrasting colors apart from black and white, is called a ‘module’. Simply put, QR Codes are 2D versions of barcodes.Ī simple black-and-white QR Code consists of many tiny black and white squares that form patterns so that information can be embedded within it. Getting QR Code size right will ensure easy scannability, regardless of where you plan to deploy them. The combination of size and scanning distance in particular instances can even render your QR Codes unreadable. This is because QR Code size correlates with scannability.Įven if users want to scan your codes, the QR Code size might hinder them from doing so. QR Code size does matter-and overlooking this can cost you a lot of scans.
