Hello [drbhonsle95](https://forum.digikey.com/u/drbhonsle95) - welcome to the Forum community!. The read distance is calulated in meters, by frequency on the two graphs at the bottom of page 2 of the [datasheet](https://rfid.averydennison.com/content/dam/rfid/en/products/rfid-products/data-sheets/datasheet-AD-172u7.pdf). It looks like the range is from .5 meters to a little over 4.6 meters.
