The record margin is 45 points. The San Francisco 49ers beat the Denver Broncos 55–10 in Super Bowl XXIV, and no other final has reached that gap.
13 of 60 Super Bowls were decided by at least 20 points. Five reached 30, while 23 finished within one score. The blowouts stick in memory because most Super Bowls have not looked like them.
The 1980s produced the most 20-point wins with 4. The 1990s are next with 3. That cluster says more about a handful of lopsided Sundays than it does about an entire era.
The San Francisco 49ers, Dallas Cowboys, and Tampa Bay Buccaneers show up more than once on the winning side of a 20-point game. The Denver Broncos, Kansas City Chiefs, and Miami Dolphins appear more than once on the losing side. A long Super Bowl history can hold both a championship masterpiece and a night a franchise would rather forget.
A final margin tells us how far apart the teams finished, not the exact moment or tactical reason the game broke open. The quarter-by-quarter score history shows whether the separation came early or after a close first half.

How the totals work
Years refer to the calendar year when the Super Bowl was played. Franchise totals follow the current franchise across relocations and team-name changes. Co-MVPs count as two awards in one game. Current franchises with no appearance are included with zero trips rather than omitted.
