MLB Ballpark Types

How each MLB ballpark handles the elements - enclosed domes, retractable roofs, and open-air fields.

The type of roof - or lack thereof - fundamentally changes the game day experience. Enclosed ballparks offer climate-controlled comfort throughout the long April–October season. Retractable roofs give the best of both worlds. And open-air ballparks deliver the raw, weather-dependent atmosphere that many baseball fans prefer. Here's how all 30 MLB ballparks break down.

Open Air

Of the 30 MLB ballparks, 22 are open air, 7 have a retractable roof and 1 is indoor.

Open air ballparks average 40,989 seats and retractable roof ballparks 42,228; the newest of each is Truist Park (2017) and Globe Life Field (2020).

Fixed

Fully enclosed, climate-controlled ballparks. Games are always played indoors regardless of weather - ideal for hot or rainy climates. Tailgating still happens outdoors before first pitch.

Ballparks with roofs that can open or close based on weather. Climate-controlled when closed, open-air feel when open. Perfect for enjoying sunny days while staying protected from rain during the April–October season.
