The invention discloses a method for measuring an ultra-long cross beam of a double-tower cable-stayed bridge, and relates to the technical field of bridge construction measurement. According to the measurement method, feature points A1 and D1 at the two ends of one side of the cross beam in the transverse bridge direction are measured through a measurer, a coordinate system is established with the feature points A1 and D1 as control points, measurement coordinates of feature points A2 and D2 at the two ends of the other side of the cross beam in the transverse bridge direction are obtained through a measurement device, adjustment coordinates of A2 and D2 are obtained through adjustment calculation, and the adjustment coordinates of A2 and D2 are calculated. According to the method, the measurement error of the measurement coordinates of the feature points A2 and D2 is judged according to the measurement error of the measurement coordinates of the feature points A2 and D2, and it is guaranteed that control re
