We present effective temperatures and angular radii for eleven helium-rich subdwarf B stars. These are measured using spectral energy distributions from archival IUE spectra and existing optical and infrared photometry. The data have been analysed using a grid of high-gravity helium-rich LTE model atmospheres and a -minimization procedure. The parameters derived here allow for independent verification of the parameters derived from the analysis of optical spectra.
