Aziziye was 91.4 m (299 ft 10 in) long overall, with a beam of 16.9 m (55 ft 5 in) and a draft of 7.9 m (25 ft 11 in).
The hull was constructed with iron, incorporated a ram bow, and displaced 6,400 metric tons (6,300 long tons; 7,100 short tons) normally and 4,211 t (4,144 long tons; 4,642 short tons) BOM.
She had a crew of 26 officers and 335 enlisted men as completed, but only 250 after 1894.

The ship was powered by a single horizontal compound engine which drove one screw propeller.
Steam was provided by six coal-fired box boilers that were trunked into a single, retractable funnel amidships.
The engine produced a top speed of 13.5 knots (25.0 km/h; 15.5 mph) on sea trials, though by 1891, decades of poor maintenance had reduced the ship's speed to 6 knots (11 km/h; 6.9 mph).
Aziziye carried 750 t (740 long tons; 830 short tons) of coal.
A supplementary barque rig with three masts was also fitted.

The ship was armed with a battery of one 229 mm (9 in) rifled muzzle-loading (RML) Armstrong gun and fourteen 203 mm (8 in) RML Armstrongs.
These were supplemented with ten 36-pounder guns, which were also manufactured by Armstrong.
The 229 mm gun was placed on the upper deck, forward, and the rest of the guns were mounted on each broadside.
The ship's wrought iron armored belt was 140 mm (5.5 in) thick, and was capped with 76 mm (3 in) thick transverse bulkhead at either end.
Above the belt were strakes of armor 127 mm (5 in) thick that protected the battery, transverse bulkheads 114 mm (4.5 in) connected the battery armor.
