A novel approach for quantitative measurements of grain boundary (GB) excess volume has been developed using correlative analytical transmission electron microscopy (TEM) and successfully demonstrated for several simulated symmetrical  tilt GB configurations as well as for the experimental case of an Al bicrystal containing a near Σ13 GB with an additional twist component. The reliability and precision of this new approach is analyzed and the limitations are discussed.
