We present a distance to NGC 4527, the host galaxy of the type Ia SN 1991T,measured by surface brightness fluctuations. This supernova has been labelled``peculiar'' both on the grounds of its spectroscopic behaviour and itsapparent overluminosity with respect to other supernovae. The distance modulusto NGC 4527 and thus to SN 1991T is 30.26+-0.09. This relatively short distancelargely removes the discrepancy with other Ia supernovae having similarlight-curve characteristics and also removes the motivation for interpreting SN1991T as a super-Chandrasekhar explosion. However, the reddening uncertaintyresults in significant uncertainty of the absolute magnitudes.Comment: 7 pages, 2 Postscript figures, accepted for publication by Astronomy  and Astrophysic
