How to Level a Pool Table (DIY Guide)

I get phone calls about this all the time. "Greg, my table used to play even, but now the balls drift toward one end." Or one corner sits lower than the others.

Most of the time, your pool table has gone out of level. It's not broken. It's fixable. Sometimes you can fix it yourself.

Let me walk you through how to check if your table is level, what's probably causing it, and when you need to call somebody like us.

Why Leveling Matters

A pool table plays off geometry and physics. The balls need to roll true. If one end is higher than the other, even by a quarter inch, the balls will drift. Your game gets thrown off. Angles you used to make stop working.

A level table is a playable table. An out-of-level table is frustrating.

The Ball Test

Here's the easiest way to check: grab a ball and place it in the center of the table. Don't roll it. Just set it down gently and let go.

If it rolls toward any corner or rail, your table is out of level. If it sits still, you're good.

Repeat this in several spots across the table. Sometimes one area is level but another isn't, which usually means a leg issue rather than a slate issue.

The Carpenter's Level Test

For a more precise check, use a carpenter's level. Place it on the slate in different directions:

• Left to right across the middle
• Front to back down the center
• Both diagonals

Write down where the high spots and low spots are. This tells you exactly which leg or legs need adjustment.

The Shim Method for Small Adjustments

Most pool tables sit on legs that screw into the frame. If your table is slightly out of level, you can use shims to adjust the low legs.

1. Identify which leg is on the low side based on your level test
2. Loosen that leg slightly (you may need a helper to lift the corner)
3. Slide a shim under it (thin wood, plastic spacer, or even folded playing cards for tiny adjustments)
4. Tighten the leg back down
5. Re-check with the level

You're looking for very small adjustments. A sixteenth or eighth of an inch at a time. Too much and you overcorrect.

This method works for minor leveling issues. For anything more than a quarter inch out, you need professional help.

What Causes Tables to Go Out of Level

• House settling: This is the most common cause. Houses settle over time, and floors that were level five years ago might not be now.
• Humidity changes: Wood frames expand and contract with humidity. Kentucky summers are humid. If your game room doesn't have climate control, the frame can shift seasonally.
• Floor stress: Moving heavy furniture nearby, renovations, or even a lot of foot traffic on an older floor can shift things.
• The table got bumped: Someone leaned on it hard, moved it slightly, or it got jostled during a move.

How Often to Check

If your table is in a temperature and humidity-controlled room, check it once a year. If the room has variable conditions (garage, unfinished basement), check it twice a year.

A quick check takes five minutes and saves you from weeks of shots that don't feel right.

When to Call a Professional

Call us if:

• The table is more than a quarter inch out of level
• Shimming isn't fixing the problem
• The balls roll consistently in one direction even after adjustment
• You suspect the slate has shifted (which is different from leg issues)
• The table was recently moved or the floor was recently worked on

We have professional leveling equipment that's more precise than a carpenter's level. We can tell you whether the problem is the legs, the frame, or the slate itself.

What Professional Leveling Costs

For most home tables that just need adjustment, the cost is reasonable. If the slate has shifted and needs professional re-seating, that's a bigger job, and we'll tell you upfront what you're looking at.

Don't Ignore It

Playing on an out-of-level table is like trying to bowl on a slanted lane. You learn to compensate, but once you play on a properly level table, everything clicks. If your balls are drifting, check the level. Five-minute job. If you need help, we're here.
