How the odds work
Every percentage on this site is a fan estimate, built the same way each time so the numbers can be compared and checked.
The fight rules
Fight rules: both fighters at their peak, no preparation, no allies, only their own powers and personal gear. A win is a knockout, a restraint they can't escape, or a forced surrender. The percentages are fan estimates, not official information.
The odds
Each percentage is the chance that a given Spider-Man wins a one-on-one fight under those rules. The classic Peter Parker, Earth-616's Spider-Man at his peak, sets the base ratings against every opponent. Every other Spider-Man starts from those odds and shifts them: an overall modifier for the version, plus matchup modifiers listed on its page.
Shifts are measured in points on a logistic scale: 25 points moves an even fight from 50% to about 73%, and the same shift moves much less near the extremes.
Outcome labels
Labels are from Spider-Man's side. Favored: 60% or better. Toss-up: 40 to 59%. Underdog: 15 to 39%. Long shot: under 15%.
Stats (1 to 10)
Everyone is rated on eight stats, anchored to the official handbook power grid where one exists and stretched to a 10-point scale; agility and size are added for this site.

|---|---|
| Strength | 2 average human. 4 peak human. 5 enhanced, 1 to 5 tons. 6 about 10 tons (Spider-Man). 7 heavy, 25 to 75 tons. 8 very heavy, 75 to 100 tons. 9 over 100 tons. 10 beyond measure. |
| Speed | Fight speed: reflexes and movement. 2 average human. 4 peak human. 6 quick enough to dodge gunfire (Spider-Man). 8 supersonic. 10 light speed or instant teleport. |
| Agility | 2 average. 4 trained athlete. 6 acrobat. 8 superhuman. 10 the most agile fighters there are (Spider-Man). |
| Durability | 2 average. 4 peak human. 6 survives hits that would kill a person. 8 superhuman. 10 virtually indestructible. |

Power ratings
Each power is rated from 1 to 10 for how much it does in a fight under these rules: 3 is a minor knack, 5 a solid ability, 7 a power that decides most fights against ordinary superhumans, 9 something even the strongest heroes plan around, and 10 the top of the scale.
Team fights
In the Sinister Six calculator, every villain's rating is their log-odds of beating the chosen Spider-Man one-on-one. A team's strength combines its members' ratings, so each extra villain adds a lot but less than the one before. Members of the original Sinister Six add 3 points per pair, up to 9, for teamwork. The gauntlet figure multiplies the one-on-one chances, as if Spider-Man had to win every fight in a row.
