What Sizes Can Barcode Labels Be Printed In?

Barcode size overview

Barcode labels can be printed in various sizes depending on your project. OnlineLabels offers thousands of size configurations to match nearly any application, from small product packaging to larger retail items.

Why do barcode label sizes vary?

Different products require different label footprints. Your barcode must fit comfortably while preserving correct proportions and quiet zones to maintain scannability for UPC, EAN, and GTIN barcodes.

Some of the most commonly used barcode label sizes include:

1.50 x 0.75 inches – This is our most popular general-purpose barcode label size.

2.00 x 1.00 inches – This size is especially popular for ISBN barcodes placed on books and magazines.

Why are these sizes so common?

They balance compact design with enough space for GS1 compliant bar height, width, and quiet zones. This helps ensure your barcodes scan reliably in retail and Amazon fulfillment settings.

How to choose the right size

We recommend measuring your product surface before selecting a label. This ensures your barcode fits properly without distortion or crowding.

What should I measure?

Measure the flat, available space on your packaging. The size of your product will be a crucial factor in determining the label size you choose.

  1. Measure the usable space on your product or packaging.
  2. Identify the maximum label size that will fit cleanly.
  3. Confirm that your barcode maintains correct proportions within that space.
  4. Print a sample to verify scannability.
  5. Select the final label size based on best fit and readability.

UPC, EAN, and GTIN sizing guidelines

UPC, EAN, and GTIN barcodes must follow GS1 sizing rules to ensure reliable scanning. Labels that are too small can distort the barcode, making it difficult for retailers and Amazon systems to read.

Can I shrink a barcode to fit a smaller label?

Only within GS1’s approved reduction limits. Excessive shrinking can alter bar widths and lower scan accuracy, affecting compliance and marketplace acceptance.
