Abstract
We investigate the structure of finite groups whose noncentral real class sizes have the same -part. In particular, we prove that such groups are solvable and have -length one. As a consequence, we show that a finite group is solvable if it has two real class sizes. This confirms a conjecture due to G. Navarro, L. Sanus and P. Tiep.
