  The ESA Gaia mission will bring a new era to the domain of standard candles.
Progresses in this domain will be achieved thanks to unprecedented astrometric
precision, whole-sky coverage and the combination of photometric,
spectrophotometric and spectroscopic measurements. The fundamental outcome of
the mission will be the Gaia catalogue produced by the Gaia Data Analysis and
Processing Consortium (DPAC), which will contain a variable source
classification and specific properties for stars of specific variability types.
We review what will be produced for Cepheids, RR Lyrae, Long Period Variable
stars and eclipsing binaries.
