Baseball Field Dimensions: Youth to Pro Standards

Standard MLB Dimensions

Professional baseball fields have precise specifications:

• Pitching distance: 60 feet, 6 inches from the rubber to home plate
• Base paths: 90 feet between each base
• Outfield fences: typically 325-400 feet from home plate
• Infield: a 90-foot square (the diamond)

Youth Baseball Dimensions by Age

Little League (Ages 9-12)

• Pitching distance: 46 feet
• Base paths: 60 feet
• Outfield fence: 200-225 feet

Intermediate (Ages 11-13)

• Pitching distance: 50 feet
• Base paths: 70 feet

Junior/Senior League (Ages 13-16)

• Pitching distance: 60 feet, 6 inches
• Base paths: 90 feet (same as MLB)

Why Dimensions Change

Shorter distances for younger players account for developing arm strength and running speed. Moving to full-size fields too early leads to excessive throwing stress.

Measuring Your Field

Use a steel tape measure from the back point of home plate to the center of the pitching rubber. For base paths, measure from the back corner of each base.
