Size: For UPC-A, the nominal size is 1.469 inches wide by 1.02 inches high, including the number system and check characters. The maximum recommended size, 200% of the nominal size, is 2.938″ w x 2.04″ h. The minimum recommended size is 80% of the nominal size, or 1.175″ w x . 816″ h.

Can a barcode be too small to scan?
Barcode Sizing Too Small
These dimensions, particularly the minimum sizing, are based on limitations of the scanners used to read the UPC and the printing technology used to create them. Smaller barcodes have tighter print tolerances and can be problematic for scanners.
How much can a UPC be truncated?
The UCC allows UPCs to be reduced to 80% of nominal size – magnification factor of 0.80.
How small can you make barcodes?
For example, retail barcodes like UPC and EAN are limited to an 80% minimum factor by specification and design. Do not compromise the integrity of your barcode by modifying it after export.
Does the width of a barcode matter?
3 Answers. Regular barcode (=vertical stripes) is recognized by the relative width of the lines. Thus, the horizontal height only matters for robustness against diagonal scanning.
Can you stretch barcodes?
barcodes have a fixed relationship between barcode height and width, so if one dimension is modified, the other dimension must be altered by a proportional amount. For this reason, you should NOT resize or crop these barcodes.
What is the difference between UPC-A and UPC-E?
UPC-A vs. UPC-E
The main difference between a UPC-A and a UPC-E is the size of the barcode.The seventh digit is a calculated check digit using the first 6 digits of the code. UPC-E can thus be uncompressed back into a standard UPC-A 12 digit number.
What is truncating a barcode?
In applications where the barcode is scanned using a wand (a pen shaped barcode reader) a code which has been shortened (or truncated) will still read so long as the wand can easily be passed over the full width of the code without going off the edge.
How many pixels is a barcode?
So, to encode a string of 10 characters (not including the start and stop *) you will need at around 288 pixels. If the barcode is 1 inch wide on the paper then you will need to scan at a resolution of around 300 DPI.
Minimum width and height for barcodes in images.
| Barcode Type | Number of Characters | Minimum Number of Pixels (approx) |
|---|---|---|
| UPC-E | 8 | 102 |
Do barcodes need to be a specific size?
In order for a UPC symbol to be scannable, it must be generated within the acceptable size range. When the UPC guidelines were originally published, there was a stated “standard” size UPC barcode called 100% magnification. The overall dimensions of a 100% UPC are 1.46″ x 1.02″.
Can a UPC be white?
While black bars on a white background are a very good combination, your barcode does not have to be black and white. The colour chosen must appear black under red light, so blue and green are possible options.
What is barcode module size?
The standard size for the 1D symbologies is 13 mil, these bar codes are used as reference in retail stores. Mil, also known as bar code mils are used by the bar code scanner manufactures to state the minimum bar code bar width (or barcode module width) of one bar and at what distance the barcode can be scanned.
How much white space do you need around a barcode?
The popular QR Code that is being used in marketing materials recommends a white space of 4 times the size of a module (that is the size of one of the black squares within the code) on all four sides of the code.
Can a barcode be vertical?
Description of valid horizontal barcodes can be easily generalized to vertical barcodes.Based on the size and quality parameters of the barcode, a few to 10-15 degree difference between the barcode’s angle and the ideal horizontal/vertical direction might be acceptable.
How long can a Code 39 barcode be?
43 characters
CODE 39 is the barcode developed by Intermec Corporation in 1975. Up to 43 characters including numbers, letters and some symbols can be included in the barcode. Since letters can be handled, CODE 39 is indispensable in the industrial fields and used in industries such as automotive and electronics.
How big does a UPC code have to be?
UPC
Size: For UPC-A, the nominal size is 1.469 inches wide by 1.02 inches high, including the number system and check characters. The maximum recommended size, 200% of the nominal size, is 2.938″ w x 2.04″ h. The minimum recommended size is 80% of the nominal size, or 1.175″ w x . 816″ h.
What are the disadvantages of UPC?
Poor Print Quality. One disadvantage to using UPC bar codes is that the system relies on having well-printed, undamaged bar codes for bar code readers to scan.
What does a UPC code look like?
A UPC, short for universal product code, is a type of code printed on retail product packaging to aid in identifying a particular item. It consists of two parts – the machine-readable barcode, which is a series of unique black bars, and the unique 12-digit number beneath it.
What is barcode resolution?
In a few words, barcode resolution is the overall quality of your barcode image measured in pixels per inch (PPI) on screen, and in DPI when printed onto your media—but what does that mean to you?
What is label DPI?
DPI stands for Dots Per Inch which means how many dots of printing you get per of inch.A higher DPI means a clearer and crisper print. When it comes to thermal label printers 203 dpi is standard but there are higher DPI printers. Examples of 203dpi (on the left) and 300dpi (on the right) labels.
What is barcode DPI?
The DPI stands for dots per inch and is a guideline for determining the resolution of the barcodes that you will be using.Barcode printers that have a resolution of around 200 DPI are perfect for printing large barcodes, such as shipping labels, that can still be scanned at a lower resolution.
