We investigate modifications of the well-known irregularity strength of graphs, namely, total (vertex, edge) 𝐻-irregularity strengths. Recently the bounds and precise values for some families of graphs concerning these parameters have been determined. In this paper, we determine the exact value of the total (vertex, edge) 𝐻-irregularity strengths for the ladders and fan graphs.
