Existing data have been completed by differential photometry in passbands V and Ic. Unknown parameters of this bright and partially eclipsing binary have been determined with help of a modeling software leading to a consistent solution for simultaneous data fitting. Apparently, QT Peg consists of a hot A-type dwarf and a cool subgiant in a semi-detached configuration. For the time being the 3.6 days period of the system in a circular orbit appears to be constant.
