[[Armor|Knockback resistance]] (such as from the [[Metal Box]]) causes the hitbox to fail to stun the target if it doesn't deal any knockback. However, stun duration itself is independent of knockback.

This formula also applies to having a [[reflect]]or broken in ''Smash 64'' and ''Melee'', and having {{SSBU|King K. Rool}}'s [[Belly Super Armor]] broken in ''Ultimate''.

In ''Melee'', the only attack that can stun opponents is {{SSBM|Mewtwo}}'s [[Disable]], which uses the formula <code>96 + p * 0.6 - h</code>, rounded down. '''p''' is the opponent's percent after Disable hits, while '''h''' is a handicap equal to 15 if the victim has less stocks or points than the user (depending on battle mode). As a result, players that are currently losing will be stunned for slightly less time, and the minimum possible stun time without button mashing can be either 96 or 81 frames. Button mashing reduces Disable's stun time by 5 frames per input.

In ''Brawl'', attacks that stun opponents use a general formula of <code>60 + 50 * h + 15 * (3 - r) + KB</code>, rounded up, with the factors corresponding to the following:

*'''h''' and '''r''' are both placing factors much like the one used in ''Melee'', but they make stun time even more variable based on the user and victim's stock difference (or points in a time battle). '''h''' (handicap) controls stock deficit, being equal to 0.24 if the user is one stock behind the opponent, and 0.48 with two or more stocks behind. On the other hand, '''r''' (rank) controls stock leads, being equal to 1.875 if the user is one stock ahead of the opponent, and 2.7 with two or more stocks ahead. If both characters' stocks (or points) are equal, both factors are equal to 0.

*'''KB''' is the numerical [[knockback]] amount inflicted by the stunning attack, using a [[weight]] of 100 for every character.

In ''Smash 4'' and ''Ultimate'', the general stun formula is slightly modified to <code>'''76''' + 50 * h + 15 * (3 - r) + KB</code>, increasing stun time by 16 frames relative to ''Brawl''. Button mashing still reduces stun time by 6 frames per input, which is now 10.8 for button inputs due to the altered mashing mechanics, though they cannot be registered as quickly as stick inputs.

[[Mewtwo]] returns as a playable character after ''Brawl'', alongside its Disable move, making stun once again part of a playable character's moveset without items. However, Disable uses another formula for its stun duration, separate from the general one. This formula is <code>p * 1.1 + KB</code> in ''Smash 4'', and <code>'''p * 1.3''' + '''16''' * h + '''16''' * (3 - r) + KB</code> in ''Ultimate'', both rounded up; as a result, unlike general stunning moves, the opponent's percent after Disable hits is a factor in its duration alongside the resulting knockback value, and in ''Smash 4'', it is not affected by Mewtwo's placing relative to the opponent.

In ''Ultimate'', the placing factors are also different; '''h''' (stock deficit) is equal to 0.2 for a -1 difference, and 0.45 for -2 or lower, while '''r''' (stock lead) is equal to 1.2 for a +1 difference, and 1.4 for +2 or higher. As a result, Disable stuns opponents for 4 more frames with a -1 difference in stocks (or points), 8 more frames with a -2 difference or lower, 19 less frames with a +1 difference, and 22 less frames with a +2 difference or higher.
