There are many different type of barcodes accessible. 

Choosing the best one to use might be difficult because it’s important to know the barcode sizes

To help you understand more, we make this detailed post about barcodes and its standard size.

Let’s check it out!

What Goes Into A Bar Code? 

While it may appear like barcodes have been around for a long time, a barcode didn't take off until the 1970s. 

What to know about barcode? It’s easy to know “when were barcodes invented?”. 

In 1949, Bernard Silver, a graduate student at Drexel Institute, and his fellow graduate student Norman Joseph Woodland was first created the barcode.

A barcode is the machine-readable equivalent of the UPC, or universal product code, which is a 12-digit number allocated to items. 

The 12-digit code's many components have various functions.

  • The first six numbers indicateds the manufacturer's identification number

  • The item number is the next five numbers

  • The last digit is the check digit

The Uniform Code Council accepts applications for UPCs from manufacturers. 

Following acceptance, a company can pay an annual fee to join the UPC system and get a unique manufacturer identification number that will be used for all of its barcodes.

The item number is unique to each product. 

The manufacturer is responsible for issuing such numbers and avoiding any duplication of numbers for multiple SKUs. 

Finally, the digit check is a single number that confirms the validity of your barcode number. The GS1 check digit calculator can help you find the exact number for a product.

Some people may misconception of the barcode number indicating the product's country of origin. 

Note: Barcode prefixes do not identify barcode country of origin for a specific product. 

They only supply numerical capacity for the GS1's distribution of barcode prefixes to various nations.

The cost of retail barcode packages varies depending on how many barcodes you need. Barcodes price for packages begins at US$39.

And you can absolutely search for your product on Amazon barcode search.

Does The Size Of A Bar Code Matter?

Barcodes serve a variety of functions, ranging from a QR Code advertisement on the side of a bus to an Intelligent Mail tracking barcode on an envelope. 

The size of the barcode has a large influence on its utility. 

A barcode that is too tiny for an advertisement will go overlooked and will be ineffective. 

A tracking barcode that is too big will leave little area for other crucial information such as who the mail came from and who it is being forwarded to.

Aside from their function, these barcodes may be scanned in a variety of ways. 

One may use a smartphone to target a passing customer, while the other could be interpreted using a portable scanner. 

So, the readability of these two methods will differ depending on the size of the barcode.

Image-based readers found on most smartphones will work fine as long as the barcode can be easily framed in the camera's frame and is not tiny.

There are typically criteria that should be fulfilled for portable LED type readers to ensure readability. 

The larger these single bars are, the closer your scanner is to the barcode

These are generally indicated by a minimum barcode element width and may be found in the scanner's handbook. 

This smallest element width corresponds to a single bar within the barcode. The larger these parts are, the closer your scanner is to the barcode.

The depth of field relates to the distance between the scanner and the barcode being scanned. 

Scanners have a distance restriction, and if it is surpassed, the barcode will not be detected since it is out of range. 

You will be able to scan your barcodes with ease if you follow the criteria of your reader.

What Are The Barcode Sizes?

Any barcode has a worldwide suggested size that has been set to ensure reading. 

However, product sizes vary greatly, and it may be required to reduce or increase both the height and weight of a barcode.

So the primary barcode size guidelines are that barcodes can be adjusted between 80% and 200% of their specified maximum size to ensure dependability. 

In further detail, they can be lowered in height by 50% and in width by 20%.

However, it is usually recommended to utilize a magnification (barcode size) that is somewhat more than the minimum.

What Overall Dimensions Should My Bar Code Be?

It is essential to make sure that your barcode is neither too large or too small for both your label and scanners. 

Larger barcodes and UPCs are generally simpler to scan, but your alternatives may vary depending on your design and overall label area. 

A common barcode is 1.469 inches wide by 1.02 inches high, but you can change the size as needed as long as you keep within the barcode minimum size and maximum size.

Nominal size

1.469" wide x 1.02" high

Minimum recommended size

80% of the nominal size or 1.175" wide 

Maximum recommended size

200% of the nominal size or 2.938" wide

Width is far more important than height!

The width affects the distance between the bars and how effectively the laser can discern between them.

Magnification is the size of the barcode.

Magnification can vary within specified limitations. If a barcode is not within these parameters, it may not scan. 

Any reduction in magnification below the nominal size (100%) may affect dependability.

So, let’s check the dimensions that some common barcodes should be below!

UPC

UPC barcode size is also known as magnifications or magnification factors. 

A UPC's nominal size is 100% magnification factor or 1.469 inches wide (from the far left hand side number to the far right hand side number) by 1.02 inches height (from the barcode's top to the human-readable numerals' bottom). 

The minimum size for UPC barcode is 80% magnification factor (80% of the nominal size), and its maximum size is 200% magnification factor (200% of the normal size).

EAN-13

The nominal dimension of a 100% EAN barcode size, including the right and left light margin areas, is 37.29mm wide and 25.93mm high.  

The barcode symbol must have an opacity of 80% to 200%.

EAN-8

If the form of the box or label legitimately and reasonably prevents the printing of a regular EAN-13 digit barcode symbol, an EAN-8 digit barcode symbol is another possibility.

The basic guideline of EAN 8 barcode minimum size is that the printing area should not exceed 8,000mm2 unless the product is cylindrical with a diameter of less than 30mm. 

The nominal dimension of a 100% EAN-8 digit barcode sign, including the right and left right margin areas, is 26.73mm wide and 21.31mm high.

The barcode sign can be printed as tiny as 80%.

Due to the restricted number of GTlN-8 digits available, it is only assigned if absolutely essential. 

A sample label or a copy of the exact size of the artwork should be submitted when applying for a G TIN-8 digit.

ITF-14

The magnification factor for the ITF 14 barcode size can range from 25% to 100%.

A minimum magnification factor of 50% should be employed to allow efficient reading in any scenario, including conveyorised scanning.

ITF-14 barcodes with magnifications less than 62.5% should not be printed directly on corrugate using traditional (plate-based) techniques.

GS1-128

The height of a GSI -128 for widespread distribution is 32mm.

If space restrictions prevent the barcode from being printed at the minimum barcode size, it must never be less than 13mm height.

Frequently Asked Questions (FAQs)
1. Can a barcode be any size?

The nominal or 100% size barcode can be adjusted, and the size chosen will rely on the printing method and the quality of the inks and substrates used.

2. What is the standard barcode size?

The most common barcode for retail product labeling is the UPC (Universal Product Code). 

It can be found at almost any grocery shop in the United States. A 12-digit numeric-only number is encoded using the symbology. 

The GS1 US assigns the first six digits. The manufacturer assigns the next five numbers. The last digit is a modulo ten check digit.

3. What is the smallest barcode size?

The magnification of UPC barcodes can range from 0.8 to 2.0. At 0.8, the barcode is reduced to 80% of its normal size. 

The UPC barcode size specifications measure 1.175 inches wide by 0.816 inches height at this magnification, which is the smallest barcode that can still be scanned. 

This size, however, makes it more difficult for scanners to read the barcode information, and some will not scan at all.

Conclusion

One of the crucial stages in the labeling process is creating the barcode and UPC for a product label. It's time to focus on suitable barcode sizes for your product and choose a reliable printing firm to provide you with the high-quality labels you want.
