The MLB Park Factors tool pulls data and shows you how every MLB stadium affects offensive production. Filter by right-handed hitters (RHB) or left-handed hitters (LHB) to see handedness splits that matter for your DFS lineups and sports bets. Every park factor index is set to 100 as league average. Anything above 100 is a hitter-friendly park, anything below 100 is a pitcher-friendly park. Use our park factors to target hitters playing in favorable venues on DraftKings and FanDuel MLB slates.
What a park factor is and how to read it
A park factor compares what happens in one stadium to what happens league-wide, with 100 set as average. A home run factor of 118 means that park produces about 18 percent more home runs than a neutral one, after adjusting for the quality of the teams that happen to play there. Below 100 suppresses.
The handedness split is the part worth your attention. A stadium with a short right field and a deep left field can sit near 100 overall while being a strong park for lefties and a poor one for righties. The single overall number averages that away and is close to useless for lineup decisions. Read the column that matches the hitter you are considering.
Park factors are also slow-moving. They are computed over multiple seasons because a single year of data in one stadium is mostly noise. That means they are a stable input, not something to recheck daily.
Frequently asked questions
What is a park factor?
A stadium's effect on an outcome relative to league average, with 100 as neutral.
Why do righty and lefty factors differ?
Because outfield dimensions are not symmetric. Fence distance and height differ by field, so pull-side power plays differently for each handedness.
How often do these update?
Periodically, since they are computed over multiple seasons. They are not a daily input.
Which park is best for home runs in 2026?
Sort the home run column and check the handedness split, since the answer differs for lefties and righties.
