Disordered optical substrates play a key role in photonic applications. Furthermore, structures of correlated, in particular hyperuniform, disorder are an emerging new class of photonic material enabling new ways of k ‐space engineering. Yet, there are little to no feasible technologies that allow fabrication of tailored disordered structures to facilitate a tailored optical response. This work reports on a scalable method to fabricate substrates of tailored correlated disorder by self‐stabilized colloid deposition. Easy‐to‐access experimental parameters allow to tune lateral and vertical statistics of the disordered patterns. In addition, a model is presented that allows accurate prediction of mono‐ as well as polydisperse particle patterns. Correlation of disorder of the prepared patterns is investigated by means of the structure factor and optical measurements.
