• To quantify residual porosity of the materials is important when analyzing their microstructure and functional performance. The problem becomes particularly urgent for functional (optical, laser) materials. A common way to solve it is to calculate the quantity and size of pores on the sample's cross-section. However, authors do not pay special attention to experimental data processing. Present work studies pore size distribution in 1–4 at% Nd3+:YAG transparent ceramics using experimental measurements of pore sizes determined from the cross-section. Suggested method enables one to evaluate residual porosity correctly. [Display omitted] •A new method for calculating the residual porosity has been suggested.•Original results were comparing with other known approaches.•As a model system, 1–4 at% Nd3+:YAG transparent ceramics were used.•3D models of pore distribution in the ceramic's bulk have been built.•Residual porosity values from 0.0009 to 0.0112 vol% have been determined.
