Some early estimates are that close to perihelion, the comet's tail
could span more than 90 degrees as seen from earth. Haven't read
any estimates yet on the expected angular size of the coma surrounding
the nucleus. Probably no way to predict since the composition and
size of the nucleus are not known. --Rob

Given it might be as bright or brighter than the full Moon, what size will it appear, comparatively speaking??
