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 Kit (Shims + Level)

Everything for a DIY relevel · usually under $30
  • 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

  1. 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.
  2. 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.
  3. Check all sides and both diagonals. Move the level lengthwise, widthwise, and across both diagonals so you catch twist as well as simple tilt.
  4. 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.
  5. 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.
  6. 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.

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.
