Designed by naval architect Siegfried Popper,{{sfn|Vego|1996|p=70}}{{sfn|Sondhaus|1994|p=194}} the ''Tegetthoff''-class ships had an [[length overall|overall length]] of {{convert|152|m|ftin|sp=us}}, with a [[beam (nautical)|beam]] of {{convert|27.90|m|ftin|sp=us}} and a [[draft (ship)|draught]] of {{convert|8.70|m|ftin|sp=us}} at deep load. They were designed to [[Displacement (ship)|displace]] {{convert|20000|t|LT|0|sp=us}} at load, but at full combat load they displaced {{convert|21689|t|LT|sp=us}}.{{sfn|Sieche|1991|p=133}} The propellers for the class is where differences in design began to appear between the three ships constructed in Trieste, and ''Szent István'' which was constructed in Fiume. The [[skeg]] for each propeller shaft on ''Szent István'' was a solid, blade-like fitting, unlike the strut-type skegs used in the other three ''Tegetthoff''s.{{sfn|Sieche|1991|p=137}} The hull was built with a [[double bottom]], {{convert|1.22|m|ft|0|sp=us}} deep, with a reinforced inner bottom that consisted of two layers of {{convert|25|mm|adj=on|0|sp=us}} plates. This design was intended by Popper to protect the battleships from [[naval mine]]s, although it ultimately failed both ''Szent István'' and ''Viribus Unitis'', the former being sunk by a [[torpedo]] in June 1918 and the latter by a mine in November of that same year.{{sfn|Sieche|1991|pp=133–137}} The ''Tegetthoff'' class also featured two {{convert|2.74|m|ft|0|adj=on|sp=us}} [[Barr and Stroud]] [[optical rangefinder]] posts on both the starboard and port sides for the secondary guns of each ship. These rangefinders were equipped with an armored cupola, which housed an {{convert|8|mm|in|adj=on|sp=us}} [[Schwarzlose machine gun|Schwarzlose M.07/12]] anti-aircraft machine gun.{{sfn|Sieche|1991|p=133}}

''Szent István'' had a few external variations from the other ships of her class. These differences included a platform built around the fore [[Funnel (ship)|funnel]] which extended from the [[Bridge (nautical)|bridge]] of the ship to the after funnel upon which several searchlights were installed. A further distinguishing feature was the modified ventilator trunk in front of the mainmast. The rangefinders on ''Szent István'' had an armored stand which turned 90° to the right of those on the other three ships. This was done in order to present a smaller target for the ship's broadside.{{sfn|Sieche|1991|p=133}} Perhaps the most-notable distinguishing characteristic of ''Szent István'' was that she was the only ship of her class not to be fitted with [[torpedo nets]].{{sfn|Sieche|1991|p=133}} The other three ships of the ''Tegetthoff'' class had their torpedo nets removed in June 1917.{{sfn|Sieche|1991|p=113}} The ''Tegetthoff''-class ships were manned by a crew of 1,087 officers and men.{{sfn|Sieche|1991|p=133}}
