How to Level a Pool Table
A ball that drifts is not always an unlevel table. Find out which problem you have before you start turning anything.
How these picks were made: from published manufacturer specifications, governing-body standards and the room arithmetic - not from first-hand use. We have not played on these tables. Read the method.
Level a pool table with a long spirit level laid directly on the bed - not on the rails - checking five positions: each end, each side and the center, in both directions. Adjust one leg at a time, in small increments, and re-check all five positions after every change. Most tables take two or three passes. If the level reads true in all five positions and a ball still drifts, you do not have a leveling problem: you have a bed that is no longer flat, and that is a different repair.
What you need
- A spirit level, as long as you can get. A 24-inch level is the practical minimum; 48 inches is much better because it averages out the local variation in the cloth. A short torpedo level is worse than nothing on a pool table.
- Shims. Hardwood or composite shims for a table without leg levelers. Do not use folded cardboard - it compresses over weeks and you will be back.
- A wrench that fits the leg bolts, if the table has adjustable feet rather than levelers you turn by hand.
- One good ball, round and unchipped, for the roll test.
- A helper, for any table over about 200 pounds. Lifting a corner to slide a shim under it is a two-person job and the table does not care about your back.
The method
- Brush the cloth first. Chalk ridges and raised nap deflect a slow ball, and you want the surface honest before you measure anything.
- Put the level on the bed, not the rails. Rails are attached to the frame with bolts and can be slightly out of plane with the playing surface. The bed is what the ball rolls on, so the bed is what you level.
- Measure the five positions in both directions. Across each end, along each side, and across the center - first lengthwise, then widthwise. Write the readings down. Guessing from memory is where most leveling attempts go wrong.
- Identify the low corner. With five readings you can tell whether the table is tilted along one axis, tilted diagonally, or twisted. A tilt is one leg. A twist is two diagonal legs and is the one that takes patience.
- Adjust one leg at a time, a small amount. A quarter turn of a leveler is a meaningful change on a 7-foot bed. Make one change, then re-measure all five positions before touching anything else.
- Work the twist out last. If the table rocks diagonally, bring the two low corners up alternately rather than lifting one all the way. Chasing a twist from a single corner moves the problem around the table instead of out of it.
- Re-check in a week. New tables settle, and carpet compresses under leg weight for a month or more. A table that was perfect on delivery day is often slightly out by the following weekend, and that is normal rather than a fault.
What makes the test honest
#1 · The roll test
Aramith Premier Billiard Ball Set
Phenolic resin balls. They stay round, they do not chip, and they are the cheapest upgrade that changes how a table plays.
Phenolic resin balls stay round and do not chip, which matters here for a specific reason: a roll test is only as honest as the ball you roll. An out-of-round or chipped ball drifts on a perfectly level table and sends you chasing a problem that is in your hand.
- What works
- Stays round, so the roll test means something
- Does not chip when dropped on a hard floor
- What does not
- A full set is more than you need purely for testing
#2 · Before you test anything
Pool Table Brush and Rail Cleaning Kit
Brush along the nap, not across it. A two-minute habit that adds years to a woolen cloth.
Brush along the nap, not across it. Do this before a roll test: a ridge of chalk dust or a patch of raised nap deflects a slow ball exactly the way a slope does, and brushing removes a surprising number of phantom leveling problems.
- What works
- Removes the debris that causes false roll-test results
- Two minutes, and it is cloth maintenance anyway
- What does not
- Will not fix a genuine slope - it only clears the noise
#3 · Keeping it level once it is level
Fitted Pool Table Cover
Dust is what kills cloth in a garage. A fitted cover is the cheapest item on this site and the one that pays back fastest.
Dust is what kills cloth, and a clean surface is also what keeps a roll test repeatable. A covered table stays testable, so when something does change you can tell it was the table rather than the week's accumulated chalk.
- What works
- Keeps the surface clean between sessions
- Cheapest insurance on the table
- What does not
- Only works if it goes back on
The roll test, and how to read it
Put a ball on the bed and give it just enough push to travel the length of the table slowly. Watch the last third of its travel, because that is where a slope shows. Repeat from several starting points and in both directions. A ball that consistently curves the same way, from every starting point, in both directions, is telling you about the table. A ball that curves differently depending on where you start is telling you about the cloth or the ball.
There is a third result worth knowing: a ball that rolls true along the length and drifts across the width. That is a table tilted on its long axis, which is the most common outcome on a sloped floor - and a garage slab is deliberately sloped toward the door, typically about an eighth of an inch per foot, which over a 7-foot table is close to a full inch of fall. The garage page covers what that means for setup.
What leveling cannot fix
A bed that has warped. On a composite playfield, sustained humidity swells the panel unevenly. The result is a hump or a dish in the middle of the table, which stays there regardless of what the legs are doing. The test is simple: lay the long level across the middle of the bed and look for light under the middle or the ends. If the bed itself is not straight, no leg adjustment will help.
Dead cushions. A ball that banks short is a rubber problem, not a level problem. Roll a ball firmly into a cushion: a healthy cushion returns it most of the way with a crisp sound, a dead one thuds and stops short. The service-life page covers the rest of the wear items.
Loose rails. If the rail bolts have worked loose, the table can be perfectly level and still play unpredictably, because the rail moves on impact. Going round the frame and rail bolts with a wrench each season is five minutes and prevents a problem that feels much more serious than it is.
Floors, carpet and the long game
A table on carpet will settle. The pile compresses under each leg at a rate that depends on the carpet and the weight, which is why the first month after installation needs two or three re-checks rather than one. A table on a concrete slab is more stable but starts from a sloped surface. A table on a timber floor over a span moves seasonally with the house, so an annual check belongs in the maintenance routine.
None of this is a reason to worry about the table. It is the reason to own a long spirit level and spend ten minutes with it twice a year, which is the entire ongoing commitment a level table asks for.
What we checked, and what we did not
This is a standard method rather than a tested product claim: level on the bed, five positions, one leg at a time. The garage-slab slope figure is normal building practice for drainage and should be measured in your own room rather than assumed. The slate-section point reflects how a three-piece bed is installed. We have not leveled these specific tables and publish no ratings for the products above.
