Even the finest table will play poorly if it’s not perfectly flat. After assembling your pool table, whether it’s a new purchase or a relocated one, proper leveling is a non-negotiable final step. This guide will walk you through the process professionally and thoroughly.
Why Leveling is Critical
An unlevel table causes the cue ball to roll off its intended path—a phenomenon known as “roll-off.” This undermines the fundamentals of the game:
* Shots become unpredictable: Even perfectly struck balls will curve.
* Skill is negated: A player’s ability to use English (spin) is compromised.
* Frustration increases: Games feel unfair and inconsistent.
For serious play or tournament conditions, a tolerance of less than 1/16 of an inch (approx. 1.5mm) across the entire slate is the standard.
Tools You Will Need
* High-Quality Carpenter’s Level (4-foot minimum): A shorter level is insufficient for spanning the table’s width. A machinist’s level is ideal for ultimate precision.
* Shims: Professional table mechanics use slate shims (thin, wedge-shaped pieces of slate or plastic). In a pinch, long, tapered wood shims can work temporarily.
* Wrench or Socket Set: To adjust the leg levelers on your table.
* Notepad and Pen: To record which corners or points need adjustment.
* Assistant: Highly recommended for safety and efficiency.

The Professional Leveling Process
Step 1: Initial Assembly & Placement
Ensure your table is fully assembled on a stable, solid floor. The frame and slate should be installed per the manufacturer’s instructions. If your table has adjustable leg levelers, make sure all feet are in firm contact with the floor.
Step 2: The Initial Check
Place your long level along multiple paths:
From the head (where you break) to the foot of the table.
Across the table at the head, center, and foot.
From corner pocket to corner pocket.
Mark the high and low spots on your notepad. The goal is to find the highest point on the slate; this will be your reference.
Step 3: Adjusting the Frame (Slate-Bed Tables)
Most high-leveling occurs under the slate, not the legs.
* Locate Shim Points: The slate sits on a wooden frame. The high point you identified should remain untouched.
* Shim the Low Points: Gently lift the slate at the low corner or along a low seam (for multi-piece slates) using a pry bar or by carefully lifting. Use extreme caution—slate is heavy and brittle. Insert your shim material between the frame and the slate at the point(s) you noted. Start with thin shims; you can always add more.
* Re-check: After each shim is placed, re-check with your level. The process is iterative—shim, check, adjust.
Step 4: Fine-Tuning with Leg Levelers
Once the slate itself is as level as possible, use the leg levelers for final micro-adjustments and to stabilize the table.
* Turn the leveler clockwise to raise that corner.
* Turn it counter-clockwise to lower that corner.
* Make small, quarter-turn adjustments and re-check with your level after each.
Step 5: The Final Verification
Perform a “ball roll test.” Place a cue ball on various spots on the table, particularly in the center and along the rails. Give it a gentle, smooth push with no spin. Watch for any deviation from a straight line. It should come to a stop without a noticeable curve.

Common Challenges & Pro Tips
* Uneven Floors: If your floor is significantly uneven, you may need to place sturdy, permanent shims under the table legs *before* beginning the slate-leveling process.
* Three-Piece Slate: Pay extra attention to the seams. The adjoining edges must be perfectly flush. This often requires feathered shimming along the length of a seam, not just at the corners.
* Patience is Key: Rushing leads to mistakes. This is a meticulous process. Walk away and come back with fresh eyes if needed.
* When to Call a Professional: If you have a heavy slate table, an antique, or a very uneven floor, hiring a certified table mechanic is a wise investment. They have the specialized tools, experience, and strength to do the job perfectly and safely.
Conclusion
Leveling your pool table after assembly is not just a finishing touch—it is the foundation of quality play. While it requires patience, precision, and the right tools, a DIY approach is feasible for many homeowners. By methodically checking, shimming, and adjusting, you can achieve a professional-grade playing surface that will provide years of accurate and enjoyable games. Remember, in the world of billiards, true performance starts from the ground up.
