Question about Wenger city traveler

The exact measurements of this backpack are 22 cm in length, 38 cm in width, and 42 cm in height. These dimensions are slightly larger than the typical carry-on bag size limit of 40 cm x 20 cm x 25 cm, so it might not fit within those specific constraints. However, it is designed as an expandable carry-on, which could potentially allow it to be compressed to fit within those limits, depending on how it is packed.
