The ships of the Trento class were 190 meters (623 ft 4 in) long between perpendiculars and 196.96 m (646 ft 2 in) long overall.
They had a beam of 20.6 m (67 ft 7 in) and a draft of 6.8 m (22 ft 4 in).
They had a design displacement of 10,339 to 10,344 long tons (10,505 to 10,510 t) and they displaced up to 13,334 long tons (13,548 t) at full load, though their displacement was nominally within the 10,000-long-ton restriction set in place by the Washington Naval Treaty.
Their hulls had a flush deck and a bulbous bow, the first time the latter feature was employed on an Italian warship.
The ships were completed with a pair of tripod masts, though on trials they were found to vibrate excessively, and the foremast was strengthened with two extra legs.
They had a crew of 723 officers and enlisted men, though during the war this increased to 781.
They carried a pair of IMAM Ro.43 seaplanes for aerial reconnaissance; the hangar was located under the forecastle and a fixed catapult was mounted on the centerline at the bow.

The Trento-class cruisers' power plant consisted of four Parsons steam turbines powered by twelve oil-fired Yarrow boilers, which were trunked into two funnels amidships.
The boilers were divided into three boiler rooms with four each; two powered the forward engines that drove the outboard propellers and the remaining four were allocated to the turbines that drove the center shafts.
The engines were rated at 150,000 shaft horsepower (110,000 kW) for a top speed of 36 knots (67 km/h; 41 mph), with projected service performance of 120,000 shp (89,000 kW) for 34 knots (63 km/h; 39 mph) at normal displacement.
On sea trials, Trieste only reached 35.65 knots (66.02 km/h; 41.03 mph) and Trento managed slightly less than that; these speeds could only be reached on a very light displacement, and in service, her practical top speed was only 31 knots (57 km/h; 36 mph).
The ships had a storage capacity of 2,214 metric tons (2,179 long tons; 2,441 short tons) of fuel oil, which provided a cruising range of 4,160 nautical miles (7,700 km; 4,790 mi) at a speed of 16 knots (30 km/h; 18 mph).
During refits in early 1940, funnel caps were added to reduce smoke interference with the masts.
