How to Level a Pool Table: 6 Steps to a Flat Playing Surface

Quick answer: To level a pool table, put a good carpenter’s level on the playing surface and check it in several spots: along the length, across the width, and on the diagonals. If one side is low, raise it by turning adjustable leg levelers or by putting shims under the legs. Make small changes and check again after each one. For slate tables that are far off level, or if the slate itself needs work, it may be best to call a pool table installer.

A pool table that is not level makes balls roll off line. Slow shots drift toward the low side, and that can cost you games. Leveling your table is one of the best things you can do for it. Here is a simple way to check and fix it.

Why Does a Level Table Matter?

If your table leans even a little, balls will roll toward the low side on soft shots. This is called a roll. A level table rolls true, so your shots go where you aim.

Tools You Need

A carpenter’s level. A longer one, like two feet or more, is easier to read.
Shims. Thin pieces of wood, plastic, or composite to put under legs.
A wrench, if your table has adjustable leg levelers.
A helper, if the table is heavy.

Some people also use a small machinist level for more accuracy.

Step 1: Check the Floor

Look at the floor under each leg. A table can be built perfectly but still lean if the floor is not flat. Carpet, old wood floors, and basement floors are common problems.

Step 2: Check Level in Many Spots

Lay the level on the cloth. Check:

Along the long side, near each rail
Across the short side, near each end
Across the middle
On both diagonals

Write down which way the bubble moves in each spot.

Step 3: Find the Low Corner

From your notes, figure out which corner or side is lowest. That is where you will start.

Step 4: Raise the Low Side

There are two common ways:

Leg levelers. Many tables have adjustable feet. Turn them to raise the low side a little.
Shims. Put a thin shim under the low leg. Add one at a time.

Make small changes. A tiny turn can make a big difference.

Step 5: Check Again

After each change, check level in every spot again. Fixing one corner can change the others. Keep going until the bubble is centered everywhere, or as close as you can get.

Step 6: Do a Roll Test

Roll a ball slowly down the table and back. Then roll it across. If it rolls straight and does not drift, you are in good shape. If it still drifts, check the level again in that spot.

Common Problems

Problem	Possible Cause	What to Try
Ball always drifts to one side	One side is low	Raise the low side
Level changes in the middle	Slate may sag or not be supported	Call an installer
Table rocks	One leg not touching the floor	Shim that leg
Level shifts over time	Floor moves, or table was bumped	Recheck a few times a year

Slate Tables vs Non Slate Tables

Slate tables are heavy and very flat when set up right. If the slate pieces are not lined up, leveling the legs alone will not fix it. Many people hire an installer to set and level the slate. Non slate tables are lighter, but their playing surface can sag over time.

When to Call a Pro

The table is far off level.
The slate seams are uneven.
You need to move the table.
The cloth needs to be replaced.

An installer can level the slate itself, not just the legs.

Keep It Level

Recheck your table a few times a year, and after anyone moves it. A level table plays better and makes practice more fun. For more table care, see our page on how to clean pool balls.
