Abstract Metal halide perovskites have attracted enormous attention and show huge potential as promising building blocks of next‐generation optoelectronic devices owing to their unique optical and electrical properties. For further promoting their practical applications in various fields, the synthesis of metal halide perovskites with desired characteristics is essential to satisfy the requirements of their applications. The properties of perovskites are highly related to their crystal structures and chemical compositions. The optoelectronic properties of perovskites can be altered via decreasing their dimensionality owing to the quantum confinement effect, while enlarging the crystal size of perovskite can promote the construction of device arrays with homogenous performance. In addition, modifying the chemical composition of perovskites via alloying, doping, or controlling vacancies also greatly changes their optical and electrical properties. Thus, integrating the properties modification in the synthesis process of metal halide perovskites can not only improve the productivity of the desired perovskites but also provide a great opportunity to prepare designed crystals with predictable features. The exciting progress in the synthesis of metal halide perovskites with controllably tailored properties is summarized herein. It is hoped that these technologies can promote the development of perovskites.
