The dust abundance of the interstellar medium plays an important role in galaxy physics, the chemical evolution of matter and the absorption and re-emission of stellar light. The last years have seen a surge in observational and theoretical studies constraining the dust-abundance of galaxies up to $z\sim5$. In this work we gather the latest observational measurements (with a focus on absorption studies covering metallicities in the range $6.8 < 12 + \log{(O/H)}<9$) and theoretical predictions (from six different galaxy formation models) for the dust-to-gas (DTG) and dust-to-metal (DTM) ratio of galaxies. The observed trend between DTG and DTM and gas-phase metallicity can be described by a linear relation and shows no evolution from $0Comment: Accepted for publication in MNRAS. Some corrections added
