U-112 had a displacement of 798 tonnes (785 long tons) when at the surface and 1,000 tonnes (980 long tons) while submerged. It had a total length of 234 ft 9 in (71.55 m), a pressure hull length of 183 ft 11 in (56.06 m), a beam of 20 ft 8 in (6.30 m), a height of 27 ft 1 in (8.26 m), and a draught of 12 ft 10 in (3.91 m). The submarine was powered by two 2,400 metric horsepower (1,800 kW; 2,400 shp) engines for use while surfaced, and two 1,200 metric horsepower (880 kW; 1,200 shp) engines for use while submerged.
