The right QR code size will differ depending on the advertising environment where people will be scanning your QR code from. 

One of the mistakes people make when they generate their QR code is that- most of them missed out on the right sizing. 

To make sure the QR code is scannable, you need to determine three things:

1.The scanning distance of your QR code 

2. The placement of your QR code 

3. The color of your QR code

The scanning distance of your QR code

The dimension of your QR Code is related to the scanning distance.

You need to consider all aspects of your QR code advertising setting. As it will vary from each printed marketing campaign material. 

Why is it important to consider the right dimension of your QR code?

QR code dimension

The right QR code size is an important consideration and it will vary depending on your advertising environment.

It will be different from packaging, billboards, posters, catalogs, magazines, etc. depending on where you will place them.

QR codes give a digital dimension to your product packaging, items, or artwork.

Thus, it is important that people will see it right away and can scan quickly.

Otherwise, you will only miss out on any potential scans. For this, sizing plays an important factor.

What should you consider when printing your QR code?

1. The distance between your QR code and the user's scanning device 

The QR code's size in the user's smartphone camera will be determined by this setting.

2. The size of the dots in the code 

The more information you encode into your QR code the smaller the dots get. This happens when you generate using a Static QR code.

The smaller the size of the dots, the harder it is to decode by the smartphone device.

If you have more data to input, switch to Dynamic QR codes. 

With a dynamic QR code, the codes don't get pixelated which makes them easier to scan.

3. Do not invert the color of your QR code 

Don't expect your QR codes to scan if you have an inverted QR code color.

A dark background with a light foreground color is not easily recognizable by smartphone devices.

That said, always make sure to have the foreground color of your QR code darker than the background.

Furthermore, it is almost to avoid light colors like pastel and yellow. 

Use dynamic QR code for a better scan 

Dynamic QR code

Have you ever noticed that there are some QR codes that are more pixelated than the others?

That explains the two types of QR codes: Static QR codes and Dynamic QR codes.

Static QR codes usually encode the data in the graphics itself.

When you have more data stored in it, the dots get pixelated making it hard to scan. 

If you have more data or information to store, it is always better to choose dynamic QR codes to avoid overcrowding your codes and allows for a better scan. 

Consider using a dynamic QR code generator and put your content online and link your code to it, which is much more effective and efficient. It isn't just the size that matters. 

The codes itself need to be readable as well for more points of view that is why it is important to use dynamic QR codes.

Size does matter, after all. Make sure the QR code is at least 1.2 inches (3-4 cm) in dimension for people to scan it from short distances. But this is not fixated of course.

It is important to remember that you cannot print your QR code too small otherwise it can't be scanned.

The difficulty of scanning it is determined by how small a QR code can be.

What is the right dimension of the QR code from a long-distance?

QR code right dimension

For example, if you decide to place your QR codes in billboard ads, then the size should be bigger as it will be scanned from a distance.

The farther you will place your QR code the larger the size should be. 

A QR code on a billboard 20 meters (65 feet) from where a passer-by would be scanning it would probably need to be about 2 meters (6.5 feet) across. 

Calvin Klein made a great move in their billboard ad making it twice larger than usual so they will not miss out on any scan.

The bigger your QR codes, the higher the chances you will get more scans.

Long-distance QR codes include:

An appropriate call-to-action in your QR code advertising campaign will garner more conversion rate.
