Throwing Technique and How Distance Changes With the Arc

Every backyard game that involves throwing or pitching something — a cornhole bag, a horseshoe, a bocce ball's initial toss — is governed by the same basic physics of a projectile in flight. Understanding that physics won't replace practice, but it does explain why certain adjustments to your throw change distance the way they do, which makes practicing more purposeful than just throwing harder and hoping. Every number below comes directly from this site's own Throw Distance Calculator, run at several speeds, angles, and release heights.

The three inputs that matter

The calculator (and the physics underneath it) takes three things: release speed, release angle, and release height. Speed is how fast the object leaves your hand. Angle is measured from level ground — 0 degrees is a flat, straight-ahead throw, 90 degrees is straight up. Release height is how far off the ground the object leaves your hand, which matters more than it might seem, since a throw released from shoulder height travels measurably farther than an identical throw released from the hip.

Why 45 degrees is special

Running a fixed 20 mph release through the calculator at several angles, all from ground level, shows the pattern clearly:

• 15 degrees: 13.4 feet
• 30 degrees: 23.2 feet
• 45 degrees: 26.7 feet (the peak)
• 60 degrees: 23.2 feet
• 75 degrees: 13.4 feet

Two things jump out. First, 45 degrees produces the longest distance for a given speed released from ground level — that's not a coincidence specific to 20 mph, it's a general property of this kind of physics (no air resistance, flat landing) at any speed. Second, notice that 30 and 60 degrees produce the exact same distance, and so do 15 and 75 — any two angles that add up to 90 degrees are complementary and travel the same distance from ground level. This is why a very flat, low throw and a very high, lobbed throw at the same speed can cover identical ground, even though they feel completely different to throw and look completely different in flight.

How much speed actually buys you

Holding the angle fixed at the optimal 45 degrees and varying speed shows just how sensitive distance is to how hard you throw:

• 10 mph: 6.7 feet
• 15 mph: 15.0 feet
• 20 mph: 26.7 feet
• 25 mph: 41.8 feet
• 30 mph: 60.2 feet

Distance doesn't scale in a straight line with speed — it scales with speed squared, which is why going from 10 to 20 mph (doubling speed) doesn't just double the distance from 6.7 to about 13 feet, it nearly quadruples it to 26.7 feet. This is exactly why small differences in how hard you commit to a throw produce surprisingly large differences downrange, especially at the higher end — the jump from 25 to 30 mph alone adds nearly 20 feet, more than the entire distance covered at 10 mph.

What release height changes

Throwing from a raised position — a step, a slightly elevated pitcher's box, or just a taller player's higher release point — adds real distance, and the calculator shows exactly how much. At a fixed 20 mph and 45 degrees, going from ground-level release to a 6-foot release height stretches the distance from 26.7 feet to just under 32 feet, roughly a 19% increase from that extra height alone, with speed and angle both held constant. It also extends flight time noticeably (from about 1.3 seconds to about 1.5 seconds) and adds real height to the arc's peak. For any of the pitching games on this site, a slightly higher, more upright release — rather than pitching from a crouch — genuinely does add distance, all else equal.

A flatter throw versus a lofted one, same speed

At a realistic 25 mph release speed and a 3-foot release height (about knee-to-hip height, a reasonable stand-in for a real pitching motion), a flat, low 20-degree throw covers about 33.5 feet with a peak height of roughly 5.4 feet and a flight time under a second. A lofted 50-degree throw at the identical 25 mph and 3-foot release covers noticeably farther, about 43.5 feet, but takes almost twice as long in the air (1.85 seconds) and arcs more than 15 feet high. The lofted throw travels farther in this idealized model, but it also takes much longer and is far more exposed to wind and any real-world irregularity along the way — which is a big part of why real competitive pitching, especially in horseshoes, favors a flatter, more controlled trajectory over a maximum-distance lob, even though the physics alone says the lob goes farther.

The honest limits of this model

Everything above is idealized projectile motion — no air resistance, no spin, no drag from the shape of whatever's being thrown. Real objects diverge from it in predictable ways. A cornhole bag is soft-sided, low-density, and genuinely high-drag compared to a dense, compact object; it will consistently fall short of this model's raw distance number, more so the harder (faster) it's thrown, since drag scales up with speed. A horseshoe is dense, compact, and relatively low-drag by comparison, so its real flight tracks closer to the idealized number, though its distinctive open shape still catches crosswinds more than a rounder object would. A bocce ball mostly doesn't fly through the air at all during normal play — it's rolled or gently lobbed a short distance before settling into a roll, so this projectile model applies, at best, to the very start of the throw rather than the ball's overall path down the court. None of this makes the model useless — it's genuinely good for understanding relationships (how angle trades off against distance, how speed matters more than it looks, how release height helps) — just don't expect the exact number to match a real bag landing in your yard.

Arc height and wind exposure

Flight time turns out to matter for a reason beyond just "how long until it lands" — it's also roughly how long the object is exposed to wind, side-drift, and any other real-world disturbance the idealized model doesn't account for. The lofted 50-degree throw above spends nearly twice as long in the air as the flatter 20-degree throw at the same speed (1.85 seconds versus 0.97 seconds), and it also reaches nearly three times the peak height (15.3 feet versus 5.4 feet). Both of those add up to more opportunity for a crosswind or an unexpected gust to push the object off its intended line before it lands. This is a big part of why horseshoes, played outdoors and often in genuinely breezy conditions, generally favors a flatter, faster, more controlled trajectory over a high, slow lob, even setting aside the specific 1-turn and 1¾-turn rotation techniques experienced pitchers use — less time in the air is less time for anything to go wrong with the shot.

Why a soft touch and a firm push feel so different

Cornhole players often talk about "soft" hole-shots versus a firmer "push" or "airmail" shot as if they're totally different motions, and the physics helps explain why they feel that way even when the release angle is similar. A soft, arcing toss aimed to drop straight into the hole uses a slower speed and a higher angle, trading distance efficiency for a shorter, steeper flight time that lands the bag almost straight down onto the hole with less forward roll once it lands. A firmer push or airmail shot, meant to knock another bag off the board rather than land gently, uses a flatter angle and more speed, prioritizing a fast, flat, more predictable line over a high arc. Neither is "the correct" throw — they're solving different problems, and most experienced players carry both in their repertoire and switch between them depending on what a given round actually calls for.

Practicing with this in mind

None of this replaces actually throwing the thing you're trying to get better at, but it does give practice a bit more direction than pure repetition alone. A few practical takeaways follow directly from the physics above. If you're consistently coming up short, a moderate increase in speed matters more than it feels like it should, since distance scales with speed squared. If your throws are landing short and low, check whether you're releasing from too low a stance — a slightly more upright release adds real distance for free. And if you're deciding between a flatter, faster throw and a higher, lobbed one to cover the same distance, remember the flatter throw spends less time exposed to wind and gets to the target faster, which is often worth more in practice than the small amount of extra idealized range a lofted throw provides.
