The three most common serving mistakes in tennis are an inconsistent ball toss, using a frying-pan (eastern forehand) grip instead of a continental grip, and serving with the arm alone instead of driving up with the legs. Fixing these three habits usually brings more first serves in, more pace and more spin, and it reduces strain on the shoulder. Most club players’ serves break down in exactly these places, so they are the best place to start.
This guide explains each mistake, why it matters and how to fix it, then covers other serving errors, the rules on foot faults, a practice plan and the questions players ask most.
The three mistakes at a glance
| Mistake | What it causes | The fix |
|---|---|---|
| Inconsistent toss | Rushed swings, mis-hits and double faults | Fingertip hold, straight-arm lift and a consistent release point |
| Frying-pan grip | Flat, low-percentage serves with little spin | Learn the continental grip |
| No leg drive | Low power and extra stress on the arm and shoulder | Bend the knees and drive up into the ball |
1. An inconsistent toss
If the toss wanders, the swing has to chase it, and every serve becomes different. A consistent toss is the foundation of a reliable serve.
- Hold the ball in your fingertips, not in the palm, so it leaves the hand cleanly.
- Lift with a straight arm from the shoulder rather than flicking the wrist or bending the elbow.
- Release around head height and let the ball rise just above the height you can reach with the racket.
- Place the toss correctly. For flat and slice serves, toss slightly in front and toward the hitting-arm side. For a kick serve, the toss is usually more above the head.
Drill: Toss without hitting and let the ball fall. For a flat serve, it should land on or just in front of your front foot, inside the baseline. Repeat until the landing spot is consistent. If a toss is poor in a match, catch it and start again; there is no penalty for catching a bad toss.
2. The frying-pan grip
An eastern forehand grip, sometimes called a frying-pan grip, feels natural to beginners because it lets them push the ball over. But it limits the racket’s ability to swing up and across the ball, which reduces spin and power and makes the serve less reliable.
The continental grip, often described as holding the racket like a hammer, lets the forearm pronate naturally through contact. That creates racket-head speed and allows slice, flat and kick serves from the same grip.
Drill: Serve from the service line with a continental grip, focusing on brushing up and across the ball. Move back gradually as the feel improves.
3. No leg drive
Serving with the arm alone limits power and places extra stress on the shoulder and elbow. The legs are the starting point of the serve’s kinetic chain: force moves from the legs through the hips, trunk and shoulder to the racket.
- Bend the knees as the toss goes up, loading your weight onto the legs.
- Drive upward into the ball, extending the legs as the racket swings up.
- Stay balanced. Land inside the court on your front foot after contact.
- Let the body rotate. The hips and shoulders turn into the court as the legs extend.
Drill: Practice shadow serves focusing only on the knee bend and upward drive, then add the ball. A medicine ball throw overhead can also help build the leg-to-arm connection.
Other common serving mistakes
- Rushing the motion. A smooth rhythm usually produces more speed than a hurried swing.
- Dropping the head early. Looking down at the court too soon pulls the racket down and sends the ball into the net.
- Hitting too flat on second serves. Second serves need spin for safety. Slice or kick serves clear the net higher and dip into the box.
- Poor stance. Standing square to the net limits rotation. A side-on stance helps.
- Tension in the arm. A tight grip slows the racket. Keep the arm relaxed until the swing accelerates.
Building a reliable second serve
Double faults usually come from a second serve that is simply a slower version of the first. A better approach is to use spin, not less swing speed, to make the second serve safe. Slice and kick serves travel higher over the net and curve or dip into the service box, which gives a larger margin for error. Keep the same relaxed, full swing, brush more across or up the back of the ball and trust the spin to bring it down. Practicing second serves under pressure, such as serving at the end of a session when tired or playing games where each point starts with a second serve, builds confidence for tight moments in matches.
Foot faults and serving rules
Under the ITF Rules of Tennis, the server must stand behind the baseline, between the imaginary extension of the center mark and the sideline. During the service motion, the server must not touch the baseline or the court inside it with either foot before hitting the ball, and must not change position by walking or running. Breaking these rules is a foot fault, which counts as a fault. The server has two attempts to put the ball into the correct service box. A serve that touches the net and lands in the correct box is a let and is replayed, except in competitions using no-let rules.
A simple practice plan
- Warm up the shoulder with light band work and easy serves.
- Toss practice: 20 tosses with no swing, checking the landing spot.
- Grip and brush work: 20 serves from the service line with a continental grip.
- Leg drive: 20 serves from the baseline focusing on knee bend and upward drive.
- Targets: Place cones in the corners of the service boxes and serve at them.
- Second serves: Finish with spin serves to build confidence under pressure.
Rulebook and health note
Serving rules, including foot faults, lets and time between points, are set by the ITF and applied by national associations and tournament organizers, and some formats use no-let or other variations. Check the rules for your competition. The serve places heavy demands on the shoulder and elbow, so warm up properly, build serving volume gradually and see a doctor or physiotherapist if you develop persistent shoulder or elbow pain.
Frequently asked questions
What grip should I use to serve in tennis?
The continental grip is recommended for most serves. It allows natural forearm rotation, which adds racket-head speed and lets you hit flat, slice and kick serves.
Where should I toss the ball for a serve?
For flat and slice serves, toss slightly in front of you and toward your hitting-arm side, high enough to hit at full extension. Kick serves usually need a toss more above the head.
Can I catch a bad toss when serving?
Yes. Under the ITF rules, catching or letting a poor toss drop is not a fault, so you can simply toss again.
