February 2026 Why the elbow angle is crucial ================================ The elbow angle determines the trajectory of your dart. Learn why consistency matters more than the perfect angle and how to avoid common mistakes. The elbow as the pivot point ---------------------------- In no other sport does a single joint play such a central role as in darts. While footballers work with their entire body and tennis players rotate from the hip, the dart throw reduces to a simple principle: The elbow is the fixed point around which everything rotates. Literally. The physical logic behind this is simple. The fewer moving parts a system has, the more predictable its behaviour. When you use your shoulder, upper arm and wrist simultaneously during the throw, you multiply the sources of error. Every additional movement is a variable you have to control. Using the elbow as the only active pivot point minimises these variables to an absolute minimum. Phil Taylor, 16-time world champion and for many the greatest darts player of all time, perfected this mechanics. His upper arm remained almost motionless throughout the entire throw. The complete throwing motion came from the forearm, controlled by a precisely working elbow joint. The biomechanics of the elbow angle ----------------------------------- The elbow can move in a range of approximately 0 degrees (fully extended) to 145 degrees (maximally bent). In darts you only use a small portion of this range, but this exact portion determines hits and misses. ### The starting position In the backswing phase, the elbow angle typically lies between 70 and 90 degrees. The forearm points upward, the dart is positioned at eye level or slightly above. This position is the starting point for acceleration. An angle that is too acute in the starting position means you have to accelerate over a longer distance. That might sound like more power, but it leads to more movement and thus more potential for error. An angle that is too obtuse shortens the acceleration path so much that you have to throw jerkily to generate enough speed. ### The release angle The most critical moment in the entire throwing motion is the release. In the split second when the dart leaves your fingers, the elbow angle determines the flight direction. For most successful players, this angle lies between 150 and 165 degrees. The physics explain why: At an angle of 160 degrees, the forearm points slightly upward toward the board. The dart leaves the hand in this orientation. It does not fly perfectly straight, but on a slight parabolic trajectory to the target. This trajectory automatically accounts for gravity acting on the dart. If you release at 140 degrees, the forearm points too steeply upward. The dart starts on a trajectory that would carry it past the target. At 175 degrees, the arm points almost horizontally. The dart starts on a flat trajectory and has to fight against gravity, which pulls it below the target. Why consistency matters more than the perfect angle --------------------------------------------------- The numbers 150 to 165 degrees are guidelines, not absolute requirements. Michael van Gerwen throws with a different release angle than Gary Anderson. Both are world champions. The difference between an amateur and a professional lies not in the exact angle, but in the ability to reproduce that angle. A player who consistently releases at 155 degrees will perform better than someone who fluctuates between 145 and 170 degrees, even if their average is at the theoretically optimal 160 degrees. The human brain is excellent at compensating for deviations, but only when the starting conditions remain the same. If you always release at 155 degrees and notice that the dart lands too low, your brain automatically adjusts. You unconsciously change the timing or force until the darts land on target. This compensation only works, however, when the elbow angle remains constant. If it varies, your brain cannot learn because the starting conditions keep changing. The most common elbow angle mistakes ------------------------------------ ### The dropping elbow Many players let their elbow drop during the throw. This often happens unconsciously and is barely visible to the naked eye. The result: The dart leaves the hand on a different trajectory than planned. The player compensates by adjusting the wrist or shoulder, which creates new sources of error. Dropping occurs particularly often when fatigued. The muscles that hold the elbow in position tire after many throws. In a long match or an intensive training session, the elbow sinks a little more with each throw. Consistency suffers without the player understanding why. ### The wandering elbow Even more problematic than vertical movement is horizontal movement. When the elbow drifts outward or inward during the throw, not only does the angle change, but also the throwing plane. The dart no longer flies in a straight line to the board, but on a laterally offset trajectory. This movement often arises from too much force in the throw. The body tries to dissipate the excess energy, and the elbow gives way to the side. The solution is not more control, but less force. Darts is a precision sport, not a throwing sport. ### The rigid elbow The opposite of too much movement is no movement. Some players tense their elbow so strongly that it can no longer move smoothly. The throw becomes jerky, the acceleration uneven. The dart flutters on its way to the board or lands with the point facing downward. A functioning elbow works like a well-oiled hinge. It is stable enough to hold the position, but mobile enough for smooth rotation. Finding this balance requires conscious training and regular self-checking. The elbow angle for different targets ------------------------------------- The dartboard has different heights. The triple 20 sits at a different height than the double 16 or the bull. Logically, the elbow angle would have to be different for each target. In practice, it is more complicated. ### The theory For high targets like the triple 20, the release angle would need to be larger, the arm more extended. For low targets like the double 3, the angle would need to be smaller, the arm more bent. The difference between the highest and lowest segment is about 30 centimetres. Mathematically, this requires an angle adjustment of several degrees. ### The practice The best players barely change their elbow angle. Instead, they use other mechanisms for height correction. The most common method is a minimal adjustment of body posture. For high targets, the player leans slightly forward; for low targets, they stay more upright or lean back slightly. This method has a decisive advantage: The elbow angle remains constant. The throwing motion is identical for every dart. Only the starting position changes minimally. The brain only has to automate one movement, not several different ones for different targets. An alternative method uses the wrist for fine correction. The elbow continues to work constantly, but a slight bend of the wrist changes the release direction by a few degrees. This technique requires very good wrist control and is used by fewer players. Exercises to improve elbow control ---------------------------------- ### The wall exercise Stand sideways against a wall so that your elbow lightly touches it. Now perform throwing motions without a dart. The elbow should stay against the wall throughout the entire movement. If it comes away, you are moving it too much. This exercise trains the feeling for a stable elbow. ### The mirror throw Stand in front of a large mirror and throw without a dart. Watch your elbow throughout the entire movement. Pay special attention to the moment of the imaginary release. Does the elbow move up, down or to the side? The mirror shows you errors that you cannot feel during the throw. ### The isolation exercise Take a light object in your hand. A pen works well. Rest your elbow on a table so that it cannot move. Now perform only the forearm movement used in the throw. This isolation trains the pure rotation in the elbow joint without interfering influences from the shoulder or body. ### Slow motion training Perform the throwing motion extremely slowly. So slowly that you can consciously perceive every moment. In real time, the throw happens in fractions of a second. In slow motion you recognise irregularities that would otherwise remain hidden. Pay special attention to how the elbow angle changes during the movement. How mydart analyses the elbow angle ----------------------------------- The biggest problem with the elbow angle: You cannot see it yourself. During the throw you are focused on the target, not on your arm. Video recordings help, but manual analysis is time-consuming and imprecise. Besides, you only see the result, not the variation across many throws. mydart uses AI-powered movement analysis to capture the elbow angle in real time. The app measures the angle in different phases of the throw: In the starting position, during acceleration and at the moment of release. You do not just see a single value, but the entire course of the movement. The consistency analysis is particularly valuable. mydart compares your throws with each other and shows you how much your elbow angle varies. An average value says little. But when you see that your release angle fluctuates between 148 and 167 degrees, you know what you need to work on. The app also recognises patterns. Perhaps your elbow angle is constant for the first throws of a session and then becomes increasingly irregular. Or the angle changes when you are under pressure. These insights are invaluable for targeted training. The path to a constant elbow angle ---------------------------------- Nobody achieves a perfectly constant elbow angle overnight. It is a process that can take weeks or months. The first step is awareness: You need to understand how important the elbow angle is and what mistakes you are currently making. The second step is measurement. Without objective data you train blindly. You might believe your elbow stays stable, but reality looks different. Tools like mydart give you the information you need. The third step is focused training. Work specifically on elbow control, not just on general throwing. The exercises in this article are a good starting point. Integrate them into your training routine. The fourth step is patience. Muscle memory develops through thousands of repetitions. Your body only learns the new movement if you perform it often enough. But with every training session the elbow angle becomes a little more constant, the throw a little more precise.
