Nagato had a length of 201.17 meters (660 ft) between perpendiculars and 215.8 meters (708 ft) overall.
She had a beam of 29.02 meters (95 ft 3 in) and a draft of 9.08 meters (29 ft 9 in).
The ship displaced 32,720 metric tons (32,200 long tons) at standard load and 39,116 metric tons (38,498 long tons) at full load.
Her crew consisted of 1,333 officers and enlisted men as built and 1,368 in 1935.
The crew totaled around 1,734 men in 1944.

In 1930, Nagato's bow was remodeled to reduce the amount of spray produced when steaming into a head sea.
This increased her overall length by 1.59 meters (5 ft 3 in) to 217.39 meters (713 ft 3 in).
During her 1934–1936 reconstruction, the ship's stern was lengthened by 7.55 meters (24.8 ft) to improve her speed and her forward superstructure was rebuilt into a pagoda mast.
She was given torpedo bulges to improve her underwater protection and to compensate for the weight of the additional armor and equipment.
These changes increased her overall length to 224.94 m (738 ft), her beam to 34.6 m (113 ft 6 in) and her draft to 9.49 meters (31 ft 2 in).
Her displacement increased over 7,000 metric tons (6,900 long tons) to 46,690 metric tons (45,950 long tons) at deep load.
The ship's metacentric height at deep load was 2.35 meters (7 ft 9 in).
In November 1944, the tops of Nagato's mainmast and funnel were removed to improve the effective arcs of fire for her anti-aircraft guns.
