For longer text you can also e.g. use tcolorbox:

\RequirePackage{fix-cm}
\documentclass[a4paper,11pt]{report}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[many]{tcolorbox}
\usepackage{lipsum}
\begin{document}
\begin{tcbraster}[raster columns=3,raster valign=bottom]
\tcboxfit[height=8cm]{\lipsum[1]}
\tcboxfit[height=4cm]{\lipsum[1]}
\tcboxfit[height=2cm]{\lipsum[1]}
\end{tcbraster}
\end{document}
