We have measured the limb darkened angular diameter to be $\\theta_{LD} = 0.533\\pm0.029$ mas, corresponding to a linear radius of $R_{\\star} = 1.70 \\pm 0.10 R_\\odot$. The measured angular diameter yields an effective temperature for $\\lambda$ Boo of $T_{eff} = 8887 \\pm 242$ K. Based upon literature surface gravity estimates spanning $\\log{(g)} = 4.0-4.2$ $[\\rm{cm s}^{-\\rm{2}}]$, we have derived a stellar mass range of $M_{\\star} = 1.1 - 1.7$ $M_\\odot$.
