A good rack gives both players the same thing: a fair, predictable starting position. The balls should touch, the key balls should be in their rule-defined places, and the rack should lift away without disturbing anything. The exact layout changes between 8-ball, 9-ball and 10-ball, so copying one game’s spot position into another can produce the wrong setup.
This guide follows the current World Pool-Billiard Association Rules of Play, effective 15 September 2025. Local leagues and tournaments can add their own break formats or racking procedures, so check the event sheet when competition rules matter.
Rack layouts at a glance
| Game | Shape | Ball on the foot spot | Other fixed ball |
|---|---|---|---|
| 8-ball | 15-ball triangle | The apex ball (any object ball) | 8-ball directly below the apex; one solid and one stripe on the two rear corners |
| 9-ball | 9-ball diamond | 9-ball in the middle of the diamond | 1-ball at the apex, facing the head of the table |
| 10-ball | 10-ball triangle | 1-ball at the apex | 10-ball in the middle of the triangle |
Before you place the balls
Start with a clean playing surface and a complete, matching ball set. Remove chalk crumbs or fibres around the foot spot, then check that the triangle, diamond or template lies flat. A warped wooden rack can make a tight setup unnecessarily difficult.
The foot spot is the marked point near the foot end of the table. The apex is the front ball of the rack—the ball closest to the breaker. “Toward the head of the table” means that the apex points toward the end from which the break is played.
- Roll each ball lightly to check that no debris is stuck underneath.
- Use the correct rack shape for the game.
- Place the required balls first, then fill the remaining positions.
- Build the rows so neighbouring balls touch before removing the rack.
How to rack 8-ball
Use all fifteen object balls and a triangular rack. Under WPA rules, the apex ball sits on the foot spot. The 8-ball goes directly below the apex ball, which is the centre position in the second row. Put one solid and one stripe on the two rear corners. Either group can be on either corner.
- Place any object ball at the apex and centre it on the foot spot.
- Put the black 8-ball immediately behind it, in the middle of the second row.
- Place one solid and one stripe at the two rear corners.
- Fill the other spaces without creating a deliberate pattern.
- Press the rear row forward until every row is tight, then lift the triangle cleanly.
A common informal pattern alternates solids and stripes throughout the rack. That may look tidy, but the WPA instruction is simpler: only the 8-ball and the two rear-corner groups are prescribed; the other balls are placed without a purposeful or intentional pattern.
How to rack 9-ball
Use balls 1 through 9 in a diamond. The 1-ball is at the apex, pointing toward the head of the table. In the current WPA rules, the 9-ball sits in the centre of the diamond and on the foot spot. That spot position is easy to miss if you learned a house rule that puts the 1-ball on the spot.
- Place the 9-ball at the centre position of the diamond and align it over the foot spot.
- Place the 1-ball at the front apex, toward the head of the table.
- Fill the other seven positions without a required numerical order.
- Close any gap around the 1-ball and 9-ball before checking the outside balls.
- Remove the diamond or template without pulling the apex ball away from the pack.
The tightness around the 1-ball matters because it receives the first impact. If there is a visible gap behind it, reset the rack rather than hoping the break will settle the balls.
How to rack 10-ball
Ten-ball uses balls 1 through 10 in a small triangle: rows of one, two, three and four balls. The 1-ball is the apex ball and sits on the foot spot. The 10-ball goes in the middle of the triangle. The remaining balls are placed without a purposeful pattern.
- Centre the 1-ball on the foot spot at the front of the triangle.
- Place the 10-ball in the centre position of the third row.
- Fill the eight open positions with balls 2 through 9 in no intentional pattern.
- Push the rear row forward while keeping the 1-ball fixed on the spot.
- Confirm that all four rows touch before lifting the rack.
Do not use a 9-ball diamond and add the 10-ball loosely behind it. The triangular 10-ball layout is part of the game’s defined starting position.
How to make a rack tight
A rack is tight when adjacent balls are touching and stay touching after the rack is removed. You should not see daylight between the apex ball and the balls behind it. Work from the front through the pack rather than squeezing only the rear corners.
- Set the spot ball first. Keep it centred while the other rows move forward.
- Settle the balls gently. Small forward pressure is enough; striking or grinding balls into the cloth can mark equipment.
- Check the middle. A tight outside edge can hide a gap around the key centre ball.
- Lift vertically. Raise a frame rack slightly before drawing it back so the corners do not drag balls out of position.
- Start again when needed. One stubborn gap is faster to fix before the break than to debate afterward.
Triangle, diamond or template?
| Rack type | Strength | Watch for |
|---|---|---|
| Wooden or plastic triangle | Simple, durable and familiar for 8-ball or 10-ball | A loose fit, warped frame or movement while lifting |
| Diamond rack | Quickly establishes the 9-ball shape | It still needs the correct 1-ball and 9-ball positions |
| Thin rack template | Can produce consistent ball contact when it lies flat | Competition-specific template rules and removing it without interfering with balls |
A template is not permission to ignore the rulebook. WPA regulations address when ball-rack templates may be used and how they should be removed. In organised play, use the equipment and procedure specified by the event.
Five checks before every break
- The correct number of object balls is present.
- The rack shape matches the game.
- The correct ball is on the foot spot.
- Every required key ball is in its fixed position.
- The balls are touching and remain still when the rack is removed.
Once those checks pass, move to the head end, place the cue ball as the rules allow and prepare the break. If you are deciding whether a dedicated breaker is worthwhile, see our break cues vs playing cues guide. For a wider equipment overview, start with our complete pool-cue buying guide.

Frequently asked questions
Which ball goes on the foot spot in 8-ball?
Under WPA rules, the apex ball is centred on the foot spot. It can be any object ball. The 8-ball sits directly behind it in the middle of the second row.
Does the 1-ball or 9-ball go on the spot in 9-ball?
In the current WPA layout, the 9-ball is in the middle of the diamond and on the foot spot. The 1-ball is at the apex toward the head of the table. Some leagues or events use a different spot rule, so check their format.
Where does the 10-ball go in a 10-ball rack?
The 10-ball goes in the middle of the triangular rack. The 1-ball is the apex ball and sits on the foot spot.
Do solids and stripes have to alternate in an 8-ball rack?
No. WPA rules require one ball from each group on the two rear corners, with the 8-ball directly below the apex. The remaining balls are placed without an intentional pattern.
What makes a pool-ball rack legal?
The ball count, shape, spot position and fixed key-ball positions must match the game’s rules. The balls should also be racked as tightly as possible. A league or tournament may add its own racking procedure.
