Dynamic visits of cortical structures probe for cell size.
All cells show size homeostasis owing to coordination of division with growth. In this issue, Allard et al. (2018.  J. Cell Biol.  https://doi.org/10.1083/jcb.201709171) establish that transient inhibitory visits of a negative regulator of Cdk1 to cortical oligomeric platforms increase in number and duration with cell growth, suggesting how Cdk1 activation is coupled to cell size.
