By Ryan Walker. Updated November 4, 2026: checked against the NCAA stats manual and FIVB rules, with corrected libero serving rules, standings math and serve speed records.
Fifth set of the Great Lakes Regional semifinal, my junior year. From the second set on, I’d watched their middle-back passer take a half-step left before every float serve crossed the net.
An ace is a serve that wins the point directly. It counts when the serve lands untouched, when a receiver touches it but can’t keep it in play, when the receiver is called for a fault on that first contact, or when the receiving team is out of rotation (NCAA statistics manual). Under rally scoring it’s worth one point like any other rally. The difference is that the other team never gets a playable first contact. A serve that clips the net and drops over is legal and counts too.
| What happened on the serve | Ace? |
|---|---|
| Lands in, nobody touches it | Yes (direct ace) |
| Passer touches it, ball goes out or dies | Yes (indirect ace) |
| Receiver is called for a lift or double contact on the pass | Yes |
| Receiving team is out of rotation at the serve | Yes |
| Serve clips the tape and drops in | Yes |
| Passed badly, they free-ball it over, you score on the next contact | No, the rally went on |
The serve I still think about
I’d noticed his drift in the second set. I didn’t use it until the fifth, because a read like that only works once or twice before the other coach sees it.
The serve went deep to zone 1. He was already moving left. It hit the floor and nobody touched it. It wasn’t my hardest serve of the night, not even close. The best aces I ever served were the most carefully read, not the hardest hit, and that’s the first thing I teach servers now.
Direct ace vs. indirect ace
A direct ace lands untouched. An indirect ace is touched but not kept in play: shanked off the platform, into the net, or out of bounds. Both go in the stat sheet as an ace for the server.
The indirect ace is what good servers are really hunting. Against a team that passes well, you rarely get the ball to the floor untouched. You can still make the pass so bad that the setter can’t run anything. And if the receiver gets called for a lift on the first contact, that’s your ace too.
One thing that confuses players: if your serve forces a terrible pass and your team scores on the next attack, that’s not an ace. That point goes down as a kill for whoever finished it.
The four serves that score aces
Float serve
No spin, so the ball moves late and unpredictably. Passers commit their platform early and get caught. Coach’s cue: hit through the middle of the ball with a firm, flat palm and no wrist snap. Stop your hand at contact. If you see spin, you’re rolling your fingers over the top. For most players from high school through college this is the highest-percentage ace serve there is.
Topspin serve
Forward spin makes the ball dive after it crosses the net, so it lands shorter than the passer expects. Coach’s cue: “wrap and snap”. Contact the top back of the ball, snap the wrist, follow through down not across. It’s the higher-error serve, and almost every error starts with the toss, not the arm.
Jump serve
The power serve. Contact high, a steep angle and a lot of speed. Coach’s cue: the approach does the work. Same toss, same steps, every time, and hit at the peak. In high school my jump serve was all over the place, and I spent a full year on toss and approach timing before the arm swing stopped mattering. My step-by-step serving technique has the full progression.
Jump float
A short approach and a jump, then float contact: flat palm, no spin. You get a higher contact point and more pace than a standing float, with the same late movement. It’s the most common serve in pro volleyball today. Coach’s cue: keep the wrist locked. The jump makes your body want to swing like an attack, and that puts spin on it.
The net-clip ace
A serve that catches the top of the net and dribbles over is legal under FIVB, NCAA, USA Volleyball and high school rules. It’s one of the hardest balls in the game to pass, because the passer already set their platform for the original flight. I don’t teach anyone to aim for the tape. But I do tell float servers that a flatter, lower trajectory is fine, and the occasional net-clip that drops is a bonus, not luck you should feel bad about.
How a coach actually hunts aces
Serve the seam
Watch the serve-receive pattern for a set or two and find the gap between two passers. That’s where “mine!” and “yours!” happen at the same time. One detail most servers miss: liberos are coached to take more than half of every seam. So I don’t aim at the dead center, I aim six inches toward the non-libero’s side. The libero hesitates to reach that far and the other passer assumes the libero has it.
The freezer
A player just shanked a pass, got blocked or missed a serve? The next serve goes to them. In my experience a player who just made an error is still arguing with themselves when the next ball comes. Same for a front-row hitter who just rotated into the back row and hasn’t passed in a while. In MLV there’s a 15-second clock between rallies, so that player doesn’t even get time to reset. Use a float at a speed you can keep in. The point is to make them play it, not to miss.
Target the setter
Some teams hide their setter in serve receive. If you can find them, usually tucked behind a hitter on the right side, serve the zone 1 and 2 boundary and make them pass. The setter spends the first contact on an emergency ball and there’s no quick attack. Not an ace on the stat sheet, but it’s the next best thing.
Who serves matters too. Depending on the rulebook, your libero might be one of your servers: when a libero is allowed to serve is different in high school, club, college and FIVB play, and a libero who floats a tough ball can be a real ace weapon.
Out-of-rotation aces happen more at lower levels than people think. When a team isn’t sure where each player has to stand when the ball is served, the referee calls the overlap and the point is yours.
Ace-to-error ratio: the number that matters
Every missed serve is a free point for the other team. A server with two aces and five errors in a set is costing you points. So I track aces and service errors together.
| Ratio (aces : errors) | What I tell the server |
|---|---|
| 1:1 or better | Green light, keep swinging |
| About 1:2 | Break-even. Fine if the serves you do get in are tough |
| 1:3 or worse | Back off the speed, serve to a zone, get it in |
These are coaching rules of thumb, not official numbers. For players still building a serve I care about one thing first: get 80% or more of serves in, then chase aces. If you want to see how teams track serving now, I wrote about the numbers coaches watch in modern analytics.
Late in a set the math changes. In the VNL a 3-0 or 3-1 win is worth 3 standings points and a 3-2 win only 2, and those points are the first tiebreaker when teams finish level on wins. So a missed serve at 24-23 in the fourth set, or a run of them from 24-22, can send the match to a fifth and cost a point in the table. Knowing how many sets a match can go changes how hard you serve at the end of each one.
Fastest serves on record
The most-cited radar numbers in the men’s game are 134 km/h (about 83 mph) from Ivan Zaytsev of Italy and Bartosz Filipiak of Poland, and 132 km/h from Matey Kaziyski of Bulgaria. Other figures float around online, but measurement varies a lot between events, so take any “fastest ever” claim with some salt.
And speed isn’t what scores most aces anyway. My regional ace was a float.
Why aces matter more than one point
A team that can’t pass can’t run its offense. Tough serving drags the other team’s side-out percentage down even on the serves that aren’t aces, because the setter keeps setting off a bad pass. And two aces in a row in a tight set does something to a team, and your bench gets loud. I’ve seen passers stop calling the ball after that.
Coach Ryan’s drill: target tussle
This is the drill I use when a server has good technique but can’t place the ball under pressure.
- Put four targets on the other side: deep zone 5, deep zone 1, short zone 6 just past the attack line, and the seam between zones 1 and 6.
- Call the target right before the server tosses. No time to settle.
- Ten serves per target. Track in-zone percentage, not just in-court.
- Once they hit 70% in-zone, call the target mid-toss instead.
It builds placement and decision-making under pressure, which is exactly what the service line feels like at 13-13. I fold it into the serving block of my beginner practice plans. New to some of these words? My volleyball terms list covers them all.
Ace in volleyball FAQs
A serve that wins the point directly: it lands untouched, the receiver touches it but cannot keep it in play, the receiver is called for a fault on the first contact, or the receiving team is out of rotation.
A direct ace lands without anyone touching it. An indirect ace is touched by a receiver but not kept in play. Both are recorded as an ace for the server.
Yes. A serve that clips the net and falls into the opponent’s court is legal under FIVB, NCAA, USA Volleyball and high school rules. If the receivers cannot keep it in play, it is an ace.
No. Once the receiving team keeps the ball in play, the rally continues. The point goes to whoever finishes it, for example as a kill.
Depends on the rulebook. USA Volleyball, high school (NFHS) and NCAA women’s rules let the libero serve in one rotation spot. FIVB and NCAA men’s rules do not let the libero serve at all.
Around one ace for every two service errors is roughly break-even. Better servers get close to one to one. Developing players should get 80% of serves in before they chase aces.
The most-cited figures are 134 km/h (about 83 mph) by Ivan Zaytsev and Bartosz Filipiak, and 132 km/h by Matey Kaziyski. Measurement varies between events, so treat any single record with some caution.
Micha Hancock of Penn State served 22 aces in the 2012 NCAA Tournament, the tournament record.

How can I improve on my serve?
Hey Sophie,
Here are the quick tips to improve your serve –
–
Start with the toss: The toss controls ball positioning; it should be low, steady, and directly in front of your hitting shoulder for both underhand and overhand serves.
– Use an open palm to hit the ball at its highest point and follow through completely—avoid a closed fist or floppy fingers for reliable contact and control.
– Start from a closer distance (like the 10-foot line), then step gradually back as you consistently get the serve over the net.
– Most effective technique is the “bow and arrow” form for overhand serves: extend the non-dominant hand with the ball, draw the dominant arm back, and step forward as you swing into the ball for power and control.
Drills for Improving Your serve
Ball Toss Drill: Toss and hit the ball with the flat surface of your hand for several repetitions, focusing only on technique.
Target Practice Drill: Aim serves at specific targets on the court to practice accuracy and placement; reduce target size over time to challenge yourself.
Wall Serving Drill: Stand a few feet from a wall and serve the ball against it, aiming for a marked spot to build accuracy and strength.
