How can I choose the best QR code size?

Fast response codes or QR codes are two -dimensional barcodes that contain coded information that can be read and decoded with barcode scanners that use cameras on smartphones. The design of the QR code is necessary for the creator to obtain the intended report to the viewer. For types of information, there are minimal requirements for QR size, such as a website address or contact information. The codes can be enlarged from the minimum depending on how close the user will be displayed because the distance must be sufficient to read the code. The three sections located in the corners of the square provide a way to navigate the scanner and recognize how the code is presented. It is then able to run the data in the center through a decoder program that includes a certain degree of error correction before introducing a message to the user.

minimum QR code size depends on the size of the storage containedgive. The business cards showing a code containing twenty -six personal data can be as small as 0.6 x 0.6 inches (15 x 15 millimeters). The web address requires a minimum matrix of 1,25 x 1,25 inches (32 x 32 millimeters). The codes on the restaurant that contain the entire wine list may require a nut with 2.4 inches (60 millimeters) square and contains up to 739 characters.

The proposed minimum size QR code is based on the camera range of 6 inches (152.4 millimeters). The distance of the camera distance also doubles the desired QR code size and triples the distance to triple the size. The code on the side of the building to be used from the road will probably be the size of the billboard.

Code creators should maintain QR code size practical for medium and to the likely distance of the user. For example, business cards may have a minimum size codes, as users will most often hold the card when used. Code on a movie poster closed in a glass and suspended pThe escalator will have to be larger to take into account users who are approaching and far from it. QR codes of billboards size should only be used if necessary, because they are likely to cause drivers and are impractical to shoot from too close to the building.
