Determining the fractal dimension associated with the percolating interface of chemical wave fronts, we show that two different types of reaction-diffusion fronts, propagating either into a stable or an unstable stationary state, belong to the same universality class as pure diffusion fronts. The results are deduced from microscopic simulations and stochastic partial differential equations.
