A Radon measure $mu$ is $n$-rectifiable if it is absolutely continuous with respect to $mathcal{H}^n$ and $mu$-almost all of $ ext{supp},mu$ can be covered by Lipschitz images of $mathbb{R}^n$. In this paper we give two sufficient conditions for rectifiability, both in terms of square functions of flatness-quantifying coefficients. The first condition involves the so-called $alpha$ and $eta_2$ numbers. The second one involves $alpha_2$ numbers -- coefficients quantifying flatness via Wasserstein distance $W_2$. Both conditions are necessary for rectifiability, too -- the first one was shown to be necessary by Tolsa, while the necessity of the $alpha_2$ condition is established in our recent paper. Thus, we get two new characterizations of rectifiability.
