Damage ratio is a feature in Super Smash Flash and Super Smash Flash 2 that appears in the rules of each game. Originating from the Super Smash Bros. games, its function is to alter how much knockback is given and received by each attack by a set multiplier.

Despite the name, it does not affect the damage dealt. Instead, 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.
