Alright, so I got curious the other day about just how many people can cram into Petco Park. You see these games on TV, looks like a massive crowd, and I started wondering about the actual number.

My Little Search Mission
First thing I did, naturally, was just grab my phone. Typed in something basic like “Petco Park how many seats” or “Petco Park capacity”. You know how it goes.
Got a bunch of results right away. Saw numbers popping up, mostly hovering around the low 40,000s. Some sites said one thing, some another, maybe a few hundred difference here and there. Typical internet stuff, right? Never just one straight answer.
So, I thought, let’s try and find something a bit more official. I figured the Padres’ own website or the Petco Park site itself should have the info. Spent a few minutes clicking around there. Honestly, it wasn’t super obvious. Had to dig through some ‘Stadium Info’ or ‘A-Z Guide’ type sections.
- Checked the main pages.
- Looked for an ‘About Us’ or ‘Venue Details’.
- Scanned through FAQs.
Eventually, buried in one of those sections, I found it. They listed a specific number for baseball capacity. It was right in line with what most of the other search results showed, maybe a bit more precise.
The Numbers Game
The figure I kept seeing, and the one that seemed most legit from the official sources, was around 42,000 give or take. Seems about right for a modern ballpark.

I also remember reading somewhere that the capacity can actually change a bit. Makes sense. For concerts or other events where they use the field, they can probably fit more people in, adding floor seating and all that. But for a regular baseball game, that low 40,000 number seems to be the standard figure they work with.
So yeah, that was my little investigation. Started with simple curiosity, did a quick search, got slightly different numbers, dug a bit deeper on the official site, and landed on a pretty solid figure. Took a few minutes, but now I know! Around 42,000 folks for a Padres game.
