This will require the square root of one-third = tan(30). 30 degree angles aren't too difficult with origami. Call the original square ABCD. 1. Fold A and D onto B and C. Unfold. Call this crease 'v'. 2. Fold A and B onto D and C. Unfold. Call this crease 'h'. 3. Fold D onto v in such a way as to form a crease through C. Unfold. Call the point where this crease intersects AD 'X'. Angle DCX is 30 degrees. DC/XD is in the required ratio. Similar folds will give this ratio on side AB -Jer
