How big is a river cruise cabin?

It seems as though the river cruise companies (or most cruise companies for that matter) always showcase their largest suite category cabins in their ads but in reality, most passengers end up in their regular cabins.

Every time I take a new river cruise, I try to capture some video or pictures of the cabins to share with you for size perspectives.

The one below is the AmaCerto built in 2012 by Ama Waterways which is 445ft long and holds 162 passengers

The cabins sizes shown in the video are
300 sq ft – Suite Category
210 sq ft – Twin Balcony Category BA
170 sq ft – French Balcony Category C
160 sq ft – Window Category D

Here is the deck plan of the AmaCerto
