Damage ratio is a feature that originates from the Super Smash Bros. games that is also carried over into the Super Smash Flash games. Its function is to alter how much knockback is given and received. Despite the name, it does not affect the damage dealt. All knockback in a match is multiplied by the damage ratio value, which by default is 1.0, but can be set from as low as 0.5 or from as high as 2.0.
