By taking into account the effect of toroidal magnetic field and itscorrespond heating, we determine the thickness of advection-dominated accretionflows. We consider an axisymetric, rotating, steady viscous-resistive,magnetized accretion flow under an advection dominated stage. The dominantmechanism of energy dissipation is assumed to be turbulence viscosity andmagnetic diffusivity. We adopt a self-similar assumption in the radialdirection to obtain the dynamical quantities, that is, radial, azimuthal, soundand Alfv\' en velocities. Our results show the vertical component of magneticforce acts in the opposite direction of gravity and compresses the disc, thuscompared with the non-magnetic case, in general the disc half-thikness,$\Delta\theta$, significantly is reduced. On the other hand, two parameters,appearing due to action of magnetic field and reaction of the flow, affect thedisc thickness. The first one, $\beta_0$, showing the magnetic field strengthat the equatorial plane, decreases $\Delta\theta$. The other one, $\eta_0$ isthe magnetic resistivity parameter and when it increases, $\Delta\theta$increases, too.
