Introduction: Digital photogrammetry emerges as a postural assessment technique, also being objective, low cost, with high precision, easy reproducibility of the results and possibility of archiving records. Objectives: To evaluate quantitative aspects such as the intra and inter-examiner reliability of each program (SAPO, Corel Draw and Kinovea) and compare the three softwares. Methodology: 30 photos were analyzed, being analyzed each program analysed 30 photos 3 times each their analyzes with at least 1 day of interval between the analyzes of them, being verified the angle between spinous process of C7 and external auditory canal with a design of the software's dimensional triangle. Results: The reliability of evaluators 1 and 2 between the software were: Corel Draw (intra-examiner 1: 0.983 / intra-examiner 2: 0.999); SAPO (Intraexaminer 1: 0.957 / Intraexaminer 2: 0.999) and Kinovea (Intraexaminer 1: 0.989 / Intraexaminer 2: 0.997). Regarding inter-examiner reliability, SAPO presented (0.990); Corel Draw (0.983) and Kinovea (0.991). Regarding the comparison of the head angle values between the software, the result was 0.997. Conclusion: The intra-examiner and inter-examiner evaluation using photogrammetry, using CorelDraw, SAPO and Kinovea, proved to be reliable for the analysis of the head angle, as well as for the comparison between the three softwares.
