These days Mercury is visible in the evening sky just northwest of Venus. Its horizontal parallax is twice that of Venus, so current Earth-Venus distance is about twice the current Earth-Mercury distance. A pretty picture lifted from the Web seems to agree :-) Apparent semidiameters are about the same (to one displayed decimal place, which goes with their (VERY roughly) 2:1 actual radius ratio.
2015 Nautical Almanac Commercial Edition mentions the two planets in its DO NOT CONFUSE paragraph on p. 8; Venus is the brighter object.
