The magnetic susceptibility, χ, of the itinerant antiferromagnetic compound UGa_{3} was studied under pressure up to 2 kbar in the temperature range 64-300 K. The measured pressure derivative of the Néel temperature is found to be dT_{N}/dP=-1.1 K/kbar. In order to analyze the experimental magnetovolume effect values, d lnχ/d lnV, the volume dependent electronic structure of UGa_{3} has been calculated ab initio in a paramagnetic phase by employing a relativistic full-potential linear muffin tin orbital method and including an external magnetic field self-consistently. The calculations revealed a predominance of itinerant uranium f-states at the Fermi energy, as well as a large orbital contribution to χ.
