Yes, very strange. GSMarena lists it as 6.1 inch, and its length of 150mm (5.9") might be acceptable, but the width (76mm / 3") is large.

Comparing with my Samsung A40 (5.9" diagonally), the latter is much smaller, and also lighter: https://www.gsmarena.com/compare.php3?idPhone1=9320&idPhone2...

Edit: Both smartphones have the same display aspect ratio, but the XR seems to have thicker edges. The screen-to-body-ratio is only 79%, compared to 85.5% on the A40. So it must be wider and higher.
