Analysis of the radial-velocity and light curves of detached eclipsing binaries allows to derive stellar masses and radii and in consequence enables to find a distance. The method has been already applied to several LMC binaries but in order to have the distance to this satellite galaxy well constrained more systems need to be observed. As a first step we present the analysis of the photometry of about 70 detached binaries in the LMC selected from the OGLE-II catalog of 53000 candidates for variables. If possible we combine the OGLE-II data with the photometry from other projects (MACHO and EROS) and analyze them simultaneously by means of the Wilson-Devinney code. Derived parameters are used to indicate the best candidates for distance determination and targets for future spectroscopic observations.
