Quick Answer: Leveling a pool table means checking the playing surface with a carpenter’s level in every direction — lengthwise, widthwise, and both diagonals — then raising or lowering the legs with built-in levelers or shims until the bubble stays centered everywhere. Professional releveling costs $150–$300, according to WPA Pool’s 2026 guide, while doing it yourself costs only the price of a level and shims, usually under $30. Most tables only need quarter-turn adjustments on one or two legs; below is the full step-by-step process, the tools involved, and how often to recheck.
Even a well-built slate table drifts out of level over time — wood floors settle, carpet compresses unevenly under the legs, and seasonal humidity shifts wood framing just enough to matter. A table that plays a fraction of a degree off level will send balls curving toward one pocket and cluster break shots in the same corner every time, which is exactly the kind of problem that looks like a bad table but is actually a five-minute fix.
Pool table leveling, by the numbers:
- $150–$300 is the typical cost of professional pool table releveling, depending on location and table type, according to WPA Pool’s 2026 pricing data.
- Quarter-turn increments on adjustable leg levelers are the recommended adjustment size — small enough to avoid overcorrecting a table that only needs a fraction of a turn, per WPA Pool’s leveling guide.
- The thickness of a dollar bill is roughly what one “tick” of bubble movement on a carpenter’s level represents on a pool table — a useful gut-check for how small a truly level adjustment actually is, per Academy Sports’ leveling guide.
Signs your table isn’t level
- Balls curve unexpectedly toward one pocket instead of rolling straight.
- Break shots repeatedly cluster in the same corner or side of the table.
- A rolled cue ball drifts off course or doesn’t stop where you expect.
- Cues or chalk left on the rail slide toward one end on their own.
Tools you’ll need
| Tool | What it's for |
|---|---|
| 24"+ carpenter's level (or machinist level) | Checking the playing surface in every direction |
| Adjustable wrench or Allen key set | Turning built-in leg levelers |
| Wood, metal, or composite shims | Raising legs on tables without adjustable levelers |
| Smartphone level app | Budget backup or quick spot-check between full tests |
| Cue ball | Confirming the fix with a straight-roll test |
Pool Table Leveling Kit (Shims + Level)
- Composite or metal shims resist compression better than wood over time.
- Pair with a 24"+ carpenter's or machinist level for accurate readings.
- Works for both adjustable-leg tables and fixed-leg tables that need shimming.

How to level a pool table: step by step
- Inspect the flooring. Check each leg position for uneven floorboards or carpet indentations that could be throwing off the reading before you touch the table itself.
- Find the high point. Lay your level across the center of the table in both directions to identify which corner or side sits highest — that’s your reference point for every adjustment after this.
- Check all sides and both diagonals. Move the level lengthwise, widthwise, and across both diagonals so you catch twist as well as simple tilt.
- Adjust in quarter turns. If your table has built-in leg levelers, turn them in small quarter-turn increments, rechecking the level after every adjustment rather than guessing at the full correction upfront.
- Shim low legs if there are no levelers. Slide firm, non-compressing shims under the low leg or corner until the bubble centers, favoring metal or composite shims over wood, which compresses under weight over time.
- Confirm with a ball-roll test. Roll a cue ball from several spots on the table — it should travel straight and stop cleanly, with no drift toward a pocket or side.
How often to recheck
| Check | Frequency |
|---|---|
| Cue-ball roll test | Monthly |
| Full carpenter's-level check | Quarterly |
| Dedicated inspection | Spring and fall (seasonal wood/slate shift) |
Slate seams and wood framing move slightly with humidity and temperature swings, which is why a table that tested perfectly level in June can be off by a tick or two come October — the seasonal checks catch that before it becomes a habit-forming bad break.

The bottom line
Leveling a pool table is a free-to-under-$30 DIY job if you already have a level, or a $150–$300 professional job if you’d rather not risk it. The process is simple in concept — check every direction, adjust in small increments, confirm with a rolling ball — but the small, patient adjustments are what separate a table that plays true from one that quietly cost you the game.
