Abstract: Let $ J$ be a noncommutative Jordan algebra with 1. If $ J$ has two orthogonal idempotents $ e$ and $ f$ such that $ 1 = e + f$ and such that the Peirce $ 1$-spaces of each are Jordan division rings, then $ J$ is said to have capacity two. We prove that a simple noncommutative Jordan algebra of capacity two is either a Jordan matrix algebra, a quasi-associative algebra, or a type of quadratic algebra whose plus algebra is a Jordan algebra determined by a nondegenerate symmetric bilinear form.
