The F-type eclipsing binary CD Tauri was analyzed using Stromgren intermediate-band uvby photometric data. The photometric results, combined with earlier spectroscopic results, allow calculation of absolute system dimensions. The two nearly identical components apparently lie slightly above the main sequence. The astrophysical properties of the components are similar to Procyon and to other F-type twins such as Xi Sco, Psi Vel, and HS Hya. Although there is little photometric evidence of mass exchange or other interactions, the period of this system is apparently subject to random fluctuations.
