  We present new wide-field images of the low-surface brightness Virgo Cluster
dwarf galaxy VCC 1661. The extant literature lists a broad range of radii for
this object, covering a factor of more than four, depending on the filters used
and the details of the analyses. While some studies find a radius typical of
other Virgo dwarfs and note the normality of this object, any larger spatial
extent, taken at face value, would render this galaxy the largest dwarf in the
Virgo Cluster samples. Confirmation of a large extent of dwarf galaxies has
often led to the discovery of tidal tails and would then, also in VCC 1661,
indicate a severe state of tidal disruption. Given the importance of galactic
sizes for assessing tidal interactions of the satellites with their hosts, we
thus combine our surface brightness profile with data from the literature to
investigate further the nature of this galaxy. However, our new characteristic
radius for VCC 1661 of $r_e=24.1$"$\pm7.7$" and the previously noted smooth
appearance of its isophotes are fully consistent with the remainder of the
ACSVCS dwarf galaxy population without any need to invoke tidal perturbations.
