In each duplication cycle, daughter centrioles grow to the same length as their mothers. Which mechanisms regulate this fidelity to maintain centriole length is not known. In this issue, Aydogan et al. (2018. J. Cell Biol. https://doi.org/10.1083/jcb.201801014) report a novel role for Polo-like kinase 4 (Plk4). They found that Plk4 functions in a homeostatic manner to balance growth rate and growth period to set the final centriole size.
