This generalizes growth tightness for word metrics as initiated by Grigorchuk and de la Harpe. Given a finitely generated, non-elementary group $G$ acting on a $G$--space $\\mathcal{X}$, we prove that if $G$ contains a strongly contracting element and if $G$ is not too badly distorted in $\\mathcal{X}$, then the action of $G$ on $\\mathcal{X}$ is a growth tight action. It follows that if $\\mathcal{X}$ is a cocompact, relatively hyperbolic $G$--space, then the action of $G$ on $\\mathcal{X}$ is a growth tight action.
