Sam Altman’s height remains unverified in the sources reviewed for this article. Our earlier figure of 5 ft 9 in (about 175 cm) had no traceable supporting citation. We could not substantiate it with a direct statement, an official height record or original reporting from a reputable major publication, so it should not be treated as a confirmed measurement.
Altman is an American entrepreneur and the CEO of OpenAI, the company behind ChatGPT. Before OpenAI, he led the startup accelerator Y Combinator; he became its president in 2014.
Is Sam Altman 5 ft 9 in tall?
The figure is not established by the sources listed here. OpenAI’s company information confirms his role, and Tad Friend’s 2016 New Yorker profile provides career background, but neither supports a height of 5 ft 9 in.
For the unit conversion, 5 ft 9 in equals 175.26 cm, normally rounded to 175 cm. This explains the two versions of the earlier number; it does not verify that either describes Altman’s height. There is insufficient evidence here to give an exact height or a reliable numerical comparison with another person.
What do photographs tell us?

Public-event photographs show Altman in recognizable settings. They cannot establish a precise standing height: camera position, perspective, posture and footwear affect appearances. In this TED photograph he is seated, so even a head-to-shoes view supplies no standing measurement.
