Godzilla's size is inconsistent, changing from film to film and even from scene to scene for the sake of artistic license. The miniature sets and costumes were typically built at a 125150 scale and filmed at 240 frames per second, to create the illusion of great size. In the original 1954 film, Godzilla was scaled to be 50 m (164 ft) tall. This was done so Godzilla could just peer over the largest buildings in Tokyo at the time. In the 1956 American version, Godzilla is estimated to be 121.9 m (400 ft) tall, because producer Joseph E. Levine felt that 50 m didn't sound "powerful enough". As the series progressed Toho would rescale the character, eventually making Godzilla as tall as 100 m (328 ft). This was so that it wouldn't be dwarfed by the newer bigger buildings in Tokyo's skyline such as the 242.9-meter-tall (797 ft) Tokyo Metropolitan Government Building which Godzilla destroyed in the film Godzilla vs. King Ghidorah (1991). Supplementary information such as character profiles would also depict Godzilla as weighing between 20,000 and 60,000 metric tons (22,000 and 66,000 short tons). In the American film Godzilla (2014) from Legendary Pictures, Godzilla was scaled to be 108.2 m (355 ft) and weighing 90,000 metric tons (99,000 short tons), making it the largest film version to that time. Director Gareth Edwards wanted Godzilla "to be so big as to be seen from anywhere in the city, but not too big that he couldnt be obscured". The producers of Shin Godzilla made that film's version of Godzilla even taller than the Legendary version, at 118.5 m (389 ft).
Tsuburaya originally wanted to use stop motion for the film's special effects but realized it would have taken 7 years to complete based on the then-current staff and infrastructure at Toho. Settling on suitmation and miniature effects, Tsuburaya and his crew scouted the locations Godzilla was to destroy and were nearly arrested after a security guard overheard their plans for destruction but were released after showing police their Toho business cards. Kintaro Makino, the chief of miniature construction, was given blueprints by Akira Watanabe for the miniatures and assigned 30 to 40 workers from the carpentry department to build them, which took a month to build the scaled down version of Ginza. A majority of the miniatures were built at 1:25 scale but the Diet building was scaled down to a 1:33 scale to look smaller than Godzilla. The buildings' framework were made of thin wooden boards reinforced with a mixture of plaster and white chalk. Explosives were installed inside miniatures that were to be destroyed by Godzilla's atomic breath while some were sprayed with gasoline to burn easier, others included small cracks so they could crumble easily. Optical animation techniques were used for Godzilla's glowing dorsal fins by having hundreds of cells drawn frame-by-frame. Haruo Nakajima perspired inside the suit so much that the Yagi brothers had to dry out the cotton lining every morning and sometimes re-line the interior of the suit and repair damages. The special effects crew spent 71 days on filming.
