We present measurements of a combination of the decay constants of the light pseudoscalar mesons and the gradient flow scale ${t}_{0}$, which allow us to set the scale of the lattices generated by CLS with $2+1$ flavors of nonperturbatively improved Wilson fermions. Mistunings of the quark masses are corrected for by measuring the derivatives of observables with respect to the bare quark masses.
