Here we present a first-principle based scaling for the characteristic SOL pressure scale length. It is found that the SOL width increases with the tokamak major radius, the safety factor, and the density, while it decreases with the toroidal magnetic field and the plasma temperature. The scaling is benchmarked against the flux-driven non-linear turbulence simulations that have been carried out with the GBS code. The theoretical scaling reveals good agreement with experimental data obtained in a number of tokamaks, including TCV, Alcator C- MOD, COMPASS, JET, and Tore Supra.
