Is it OK to resize the QR code ?

by 15 comments
Hello,
I want to use online QR codes generators to generate QR codes and then resize them in Photoshop to correct size as my need as the generated code is always quite huge.

So is it ok to resize or the mobile QR code reader will give error?

Sorry I dont have a mobile QR code reader so I am asking this.

Thank you

    There is no right or wrong answer to this question.

    Every QR code is different and some have more detail than others based on how much information is stored inside the QR code. Some QR codes have very small squares inside them whilst others are much larger and easier to scan.

    You will need to test your own QR code. If you want to resize it then do so and then test scanning the QR code using a number of different QR code apps. If it still works then it's fine. If not then you will need to increase the size of it.

    Having said that, the bigger you can keep your QR code the better. Not only will it be easier for people to scan but it will also draw more attention to it.

    Also remember when using a QR code that you should ALWAYS include a text version of the link either beside or below the QR code so those without QR code readers can still access the page.

    try and use a vector based qr code if you are going to scale your qr code - that way your qr code will always remain sharp

    General rule of thumb is that you want the QR code to be built in vector so that you can resize as large as you want! (Illustrator is better for this than Photoshop)

    The BIGGEST thing is to shorten the link using bit.ly or another URL Shortener..

    The reason is that every character is encoded into the QR code, so the more characters, the more squares required. That's why some QR codes look like a total MESS (and are virtually unscannable) because people embed long links.

    With a very short URL, there are only sometimes only 18 characters total, making the QR code VERY clean.

    For example, see this - which is very short - look how clean the code is:



    Encoded URL:http://j.mp/RbiDLN (18 Characters)

    The less characters (and squares), the EASIER it is to scan! This increases "scanability" for older phones with dated cameras, or placing them on larger/moving objects (never understood QR codes on busses lol).

    As long as you do a "bilinear resample" you should be OK (there is normally several options when you click the resize tool)

    Do not use the "Pixel resize" option or it will screw the QR code up completely.

    Hope it helps.

    I recommend resizing QR codes using "Nearest Neighbor" setting. It doesn't add any anti-aliasing, so it's just like zooming in with Photoshop.

    That shouldn,t be a problem. A QR code can be damate up to 30% and still working. BUT JUST MAKE sure you test your qr code. If you get a smart phone qr code readers are free most of the time...

    Hi Dsouravs
    yes, it is commonly done and comments above are all pretty much spot on..
    have a look at Resize the QR code. which is a useful lesson in QR codes and resizing.
    Cheers
