Enter a batted ball's exit velocity, launch angle and direction. See whether it clears the fence in every MLB park, by how many feet, and where the wall is too tall or too deep.
A 104 mph ball hit at 30° to center field carries about 416 feet. It is a home run in 20 of 30 parks, including Petco Park, Dodger Stadium and Angel Stadium.

Margin is carry minus what the wall demands at that distance: positive clears it. Within 5 feet either way is inside this estimate's error, so it is marked too close to call.

Carry. Distance comes from the same drag-aware model as the exit velocity calculator and the launch angle calculator, so all three pages give one ball the same number. Carry peaks in the high 20s of launch angle and falls away fast above 40°: a 105 mph ball at 49° carries about 330 feet, not the 500 a no-air-resistance formula predicts.
Fence. Each park's posted distances at the foul lines, the power alleys and center field, with the fence in between filled in along a straight line. A ball hit between two published points meets a fence somewhere between their distances.
Wall. A fly ball is falling when it reaches the fence, so it has to still be above the wall there. The taller the wall and the flatter the ball comes down, the more carry it costs: Fenway's 37 foot Green Monster takes far more than an 8 foot fence.
What it leaves out. Weather, wind, altitude, temperature and spin. Statcast tracks the real flight and uses surveyed fence profiles, so its "home run in X of 30 parks" can differ by a park or two. Sutter Health Park, the Athletics' temporary home, publishes only its foul lines and center field, so it is left out of alley directions rather than guessed.
Take the ball's exit velocity, launch angle and the direction it was hit. Work out how far it carries, then compare that with each park's fence distance in that direction, allowing for the height of the wall it has to clear. A ball that carries 360 feet to left-center is gone in a park that is 355 feet there with an 8 foot wall, and caught at the track in one that is 380.
A fly ball is coming down when it reaches the fence, so it has to still be above the wall at that distance, not just reach it. The steeper the ball comes down, the less a tall wall costs it. Fenway's 37 foot Green Monster turns some 315 foot fly balls into doubles; a 4 foot wall at Dodger Stadium does not.
It answers the same question, but it is an estimate. Statcast tracks the full flight of the real ball and uses surveyed fence profiles for every park. This calculator models carry from exit velocity and launch angle, uses posted fence distances with the gaps filled in, and ignores weather, wind, altitude and spin. Treat a ball within about 5 feet of a fence as too close to call.
Roughly 25 to 32 degrees, and lower the harder the ball is hit. Above 40 degrees a ball climbs high but loses most of its forward distance; even a 105 mph ball hit at 49 degrees carries only about 330 feet, which is a home run down the line in very few parks.
It depends on direction. Yankee Stadium's right field line (314 ft, 8 ft wall) and Fenway's right field line (302 ft, about 5 ft) are the shortest pokes, while Daikin Park's left field Crawford Boxes are 315 feet behind a 19 foot wall. Coors Field has deep fences, but thin air there adds distance that this calculator does not model.
