The Infrared Flux Method is used to obtain effective temperatures and angular diameters of 7 Ap stars, to an accuracy of around 4 and 8 per cent respectively. The temperatures obtained are lower than normally quoted for Ap stars but in agreement with recent results from other methods. Radii obtained for six of these stars using parallax values, combined with three from a previous study, do not confirm the expectation that Ap radii are in excess of those for normal A-type stars.
