For Oriole Park at Camden Yards' first nine seasons, outfield dimensions were 333 feet to left field, 364 feet to left center, 400 feet to center, 373 feet to right center and 318 feet to right. Prior to the 2001 season, in conjunction with extensive renovations to the ballpark's playing surface and drainage system, the Orioles reconfigured the ballpark with outfield dimensions that were up to seven feet larger than those used since Camden Yards opened in 1992. However, it was found that the new dimensions did not significantly improve sight lines for fans, as had been anticipated, and adversely affected the viewing angle of the batter's eye wall.

As a result, the ballpark was returned to its original dimensions before the 2002 season. The changes included moving home plate approximately seven feet closer to the outfield, to its original spot 45 feet from the backstop. In addition, the entire field was shifted several degrees to the first base side and both the left field and right field foul poles were repositioned to their original locations. The foul line measurements decreased from 320 feet to 318 feet in right field and from 337 to 333 feet in left field. The center field distance decreased from 406 to 400 feet and the deepest part of the ballpark, in left center field, decreased from 417 to 410 feet.

Prior to the 2022 season, the Orioles renovated the outfield wall from the left field corner to the bullpens in left-center field. Enhancements include the following adjustments:

• Wall height raised from 7 ft. to 13 ft.
• Distance from home plate – left field foul line: 333 ft., left field corner: 384 ft., left-center corner: 398 ft.
• Additional lighting to properly light the expanded playing surface
