Theoretical hydrogen line and continuum spectra are computed for magnetic white dwarfs for a range of parameters assuming centred and off-centred field distributions. The results are compared with the observations of the three known magnetic DA white dwarfs GD90, G99-47 and BPM25114. We find that in each case, a centred or off-centred dipole model can be found which gives reasonable agreement with available spectrophotometric data, continuum circular polarization data and spectropolarimetric data. In particular, contrary to the conclusions of some previous investigators, we find no significant discrepancy between observed values of continuum polarization and theoretical values computed on the basis of the standard magnetoabsorption theory.
