Abstract: The growth properties of de Branges spaces and their subspaces are studied. It is shown that, for each given pair of growth functions $ \lambda(r)=O(r)$ and $ \lambda_1=o(\lambda)$, there exist de Branges spaces of growth $ \lambda$ that have a de Branges subspace of growth $ \lambda_1$. This phenomenon cannot occur for a class of de Branges spaces that, in a certain sense, behave regularly along the real axis.
