This QR code minimum size guarantees that smartphones can still scan and recognize them.
But is it possible to have a QR code even smaller than the minimum size? Certainly.
Check out the examples below:
1. QR codes on fingernails
The Japanese city of Iruma uses tiny QR codes to keep track of elderly patients diagnosed with dementia.
Each QR code only measures 1 square centimeter, and authorities attach them to the patient’s fingernail.
The QR codes on fingernails contain the patient’s identification details, address, and telephone number.
A waterproof sticker seals the QR code and lasts roughly two weeks.
Authorities say this initiative is more helpful than the ID stickers on the patients’ clothing since they often don’t wear those.
It gives them access to contact details that could help reunite lost patients with their families faster.
2. QR code on diamonds
On September 18, 2020, Beijing Dexian Technology achieved the Guinness world record for the smallest QR code. Its size? 2.352 millimeters.
The QR code is so small that it requires special apparatus like a microscope to scan it.
The Chinese tech company created the QR code as a functional detail for diamonds.
Jewelry buyers can embed images and videos in the QR code and give the precious gem to their family and friends, making it a special gift that will surely warm the recipient’s heart.
PNG format vs SVG format
When creating gigantic QR codes that are still scannable, one crucial factor to consider is their format.
QR code formats are technical standards or graphic formats applied to encrypt data for storage in a computer file.
Most online QR code platforms provide two file formats for high-resolution QR codes: PNG and SVG.
PNG, or Portable Network Graphic, is a raster image file that can handle graphics with transparent or semi-transparent backgrounds.
It supports lossless data compression—the data is “packed” into a smaller file size without losing any data in the compression process.
Although they can handle high resolutions, they’re not as expandable as SVG.
An SVG or Scalable Vector Graphics is a vector file format for rendering high-resolution 2D images.
They can expand infinitely without losing any resolution.
The SVG format is the best choice for resizing QR codes as it retains all of its resolutions when scaled up or down.
No matter how large the QR codes are, the quality of the image remains high.

- What size should a QR code be?
Although there is no actual or standard QR code size, there is a recommended or ideal sizing for QR codes to ensure their scannability. For users to scan a QR code at close range, it must have a minimum dimension of 1.2 inches (3–4 cm).
- What is the minimum size of QR code pixels?
The minimum resolution for a QR code is 76 x 76 pixels or 2×2 centimeters. This is because 1 centimeter equals 38 pixels, and the smallest QR code size is 2 x 2 cm.
- Which image format is best for QR codes?
Both SVG and PNG image formats are excellent for QR codes as they allow you to preserve them in high resolution.
For huge QR codes, the best choice is SVG format so you can resize or expand the QR code indefinitely without losing any of its resolutions.
