We present photometric and spectroscopic analysis of AE For - a detached eclipsing binary composed of two late K dwarfs. The masses of the components are found to be 0.6314 +/- 0.0035 and 0.6197 +/- 0.0034 M-circle dot and the radii to be 0.67 +/- 0.03 and 0.63 +/- 0.03 R-circle dot for primary and secondary component, respectively. Both components are significantly oversized compared to theoretical models, which we attribute to their high activity. They show H-alpha, H-beta, H-gamma, Ca H and Ca K in emission, and are heavily spotted, causing large variations of the light curve.
