2026 Updated: Accurate Park Dimensions and Factors

ExpedientFalcon · 06-10-2026, 04:33 PM

In past years, I've created quickstart files with all of the MLB and MiLB park dimensions and factors updated to be realistic. This year, I opted not to purchase the game. However, I still updated my spreadsheet with the new ballparks from 2026, which anyone is free to view, use, and copy. You can find it here on Google Sheets: https://docs.google.com/spreadsheets...it?usp=sharing

Methodology:
- Park Factors calculations and spreadsheet format are based on the wonderful template by Joelman111: https://forums.ootpdevelopments.com/....php?p=4900322
- Officially listed dimensions and capacity numbers were used where available
- Elevation was obtained via GPS lookup
- Temperature and humidity numbers are monthly averages from the nearest city that had data available
- Where official dimensions were not available, satellite images were used first, then if unavailable, dimensions were estimated based on photos of the park

Dear Out Of The Park Devs:
I've been maintaining this sheet since 2023, as a response to the fact that the numbers for many parks are inaccurate. Most, but not all, major league parks have accurate dimensions in game, but the park factors are wildly inaccurate for some major league parks, including Coors, which plays like a neutral park in OOTP. Almost all minor league parks have fictional dimensions in game, which fails to represent some major factors such as the high-altitude PCL and TL leagues being hitters paradises, and then the players from those leagues not meeting expectations due to their minor league numbers being inflated. This is a real phenomenon in the MiLB which the game could easily represent, but fails to. tl;dr what I am asking is to please implement these real numbers into the game. OOTP is supposed to be the most realistic sport simulation available. Details matter. I've done all the hard work. All you need to do is copy the numbers.

Thanks. Must have been a lot of work. Hope the devs use this information to make all MLB and MiLB parks realistic. Don't mean to be picky but the Hartford park is now Dunkin' Park. Corporate decision. I live near Hartford. All the shops had to get new signage.

I'd encourage you to have a conversation with Garlon. He's the person responsible for the OOTP park factors. I'm sure he'd be glad to discuss methodology with you.

Wow, nice work!

I've been off and on working on something similar for MLB ballparks (I start too many projects and finish too few), but my focus has been on getting as accurate as possible wall distances at 13 different points. While OOTP uses 7 points and you can usually see where they got the number from (many are old and out of date), the angles at which they're taken from are not at all consistent, whereas my 13 points are. If OOTP said they'd use the 13 points, I'd definitely finish the project asap, but otherwise it's just out of personal interest.

I've also brought up that OOTP doesn't use altitude like it says it does and IMO I soundly proved it with examples, but...

Yes, from everything I can tell, both the field dimensions and altitude in OOTP are purely cosmetic. You can set all the walls to 100 feet high and 5000 feet out and it won't do anything to stats. The actual park factors are completely independent. I suspect for the MLB parks, they've most likely gotten park factors from real-world hit totals, but this is in my opinion not the best way to do it because it's self-biasing. For example, managers know that Coors is a hitter's paradise, so they aren't going to send out flyball pitchers when they're playing in Colorado, in order to mitigate the altitude affects.

Although coming back to your mention of altitude, I have also found and reported as a bug on this forum several years ago that altitude is not considered when using the Auto-Calc Park Factors button in-game, which makes that button not particularly useful.

I would be glad to, if given the opportunity. I'm not particularly sure how to get in touch with the devs, other than posting on these forums and hoping a dev sees it.

Garlon is a volunteer not a developer. Just do a search for him in the members list (under the community tab at the top of this page) and shoot him a PM.

textilemonster · 06-14-2026, 03:49 PM

If they need another volunteer, I have absolutely no life and am obsessed with correcting things.

I spent yesterday looking through the careers of minor league players from 1939 because Baseball-Reference and StatsCrew listed different affiliations for a bunch of teams* and I'm trying to find evidence for which got it right. Spent most of yesterday doing that and thought it was an excellent use of my Saturday.

*Which also got me thinking who the FRICK was in charge of these and what sources were they using? And why isn't one site more accurate than the other? They correct each other an equal amount. Like I get that affiliations can be complicated in the early, but when a team was literally owned by the Cardinals and called the Cardinals.... how do you put "Senators"? URGERFURGALLYITHAKKKK!!!

Here is an old thread on park factors.

Are there historic park factors to be found anywhere?

Garlon · 06-17-2026, 12:54 AM

The game ballpark factors are based on the actual 3yr RHB and LHB data from 1903-2024.

For the 19th century the ballpark factors are generated with a formula to recreate the scoring environment of those ballparks.

Anyone can make their own mod by replacing the era_ballparks file with their own version and share it with the community. The game will pull the factors from columns AF through AM from the file.

The BA factor is actually a BABIP factor.

The 2B and 3B factors are the relative rates of non-HR hits that become doubles and triples.

The HR factor is based on HR per AB minus Strikeouts relative to the league rate.
