How to Level Your Turntable for Better Sound

Why Leveling Matters

A turntable that sits unevenly on its surface will cause the platter to wobble and the tonearm to lean. That small tilt changes the angle at which the stylus meets the groove, leading to misalignment and uneven wear on both the stylus and the record. Over time, you may notice distortion, sibilance, or a loss of high frequencies. The stylus is designed to track the groove with a specific vertical tracking angle, and any tilt throws that geometry off.

Leveling also prevents speed errors. A tilted platter increases friction on the bearing, which can make the motor work harder and introduce wow and flutter. Keeping the platter perfectly horizontal ensures the bearing runs true and the speed stays stable. For more on speed accuracy, see turntable speed accuracy. Wow and flutter are especially audible on sustained piano notes and strings; even a small tilt can be detected by keen listeners.

Finally, a level turntable is part of proper maintenance. The Library of Congress recommends keeping playback equipment clean and well maintained, and a level base is a prerequisite for correct cartridge setup. See how to align turntable cartridge and what is tracking force for the follow-up steps. A well-leveled table also reduces stress on the tonearm bearings, which can wear prematurely if the arm is constantly fighting gravity.

Tools You Need

You don't need expensive gear to level a turntable. A basic bubble level from a hardware store works well. Look for one that is long enough to span the platter diagonally, usually about 8 to 12 inches. For vertical leveling, a small level that fits on the tonearm headshell is helpful. Some cartridges have integrated azimuth adjustments, so you may need a hex key or a small wrench to turn the adjustment screw.

If you prefer a digital approach, you can use a digital protractor or an app on your smartphone, but physical bubbles are often more reliable because they don't depend on the phone's internal sensors. You'll also want a sturdy surface that doesn't flex under the weight of the turntable, and possibly thin shims made of paper, plastic, or metal to fine-tune the height.

• A spirit level (bubble level) long enough to span the platter.
• A small level or a protractor for checking the tonearm's vertical axis.
• Adjustable feet or shims, such as paper or plastic, if your turntable isn't level.
• A clean, stable surface or shelf to place the turntable on. For placement tips, see turntable stand or shelf placement.

Step-by-Step Leveling Procedure

Start by placing the turntable on its final surface. Make sure it sits on a solid, level base. If the surface itself isn't level, you'll need to compensate with the turntable's feet or shims. A wobbly or flimsy shelf can also transfer vibrations to the stylus, so choose a dedicated stand or a solid piece of furniture.

Remove the platter if it is easily detachable, then put the spirit level across the spindle or the platter bearing. If you leave the platter on, place the level on the platter itself, first front-to-back, then side-to-side. Adjust the feet until the bubble is centered in both directions. Some turntables have adjustable feet with locking rings; others require placing thin shims under one corner. Turn the feet in small increments and recheck each time.

Once the platter is level, spin it slowly to see if any wobble remains. A slight wobble may indicate a warped platter or bearing issue, but if the level stays centered, you're good. If the platter is warped, you might need to replace it or check the bearing. See turntable platter weight for tips on platter stability.

After setting the platter, move to the tonearm. Lower the tonearm onto a record or a non-resonant mat so that the cartridge sits in the playing position. Check that the tonearm is parallel to the record surface when viewed from the side. Some turntables have a vertical tracking angle (VTA) adjustment that raises or lowers the pivot point. If not, you may need to adjust the tonearm base or use shims under the tonearm base plate.

Finally, check azimuth: the cartridge should be perfectly vertical when viewed from the front. Place a small level on the cartridge body or headshell. If it tilts, you can adjust the azimuth screw on some cartridges. For more detailed guidance, see cartridge azimuth adjustment and vertical tracking angle.

Fixing an Unlevel Turntable

If your turntable has adjustable feet, loosen the lock nut, turn the foot to raise or lower it, and re-tighten. Rotate the turntable to access all four feet. Some high-end models have more elaborate suspension systems that allow micrometric adjustment.

If the surface is uneven, you can place non-slip pads or paper shims under the feet. Avoid using rubber that compresses unevenly; a hard shim is more stable. A thin piece of cardboard or a business card can work as a temporary shim, but for a permanent setup use metal or plastic shims intended for furniture.

For vertical adjustments, use the VTA tower if available, or place spacers under the tonearm base. Consult your turntable's manual for specific steps. Some budget tables have no adjustments; in that case, ensure the table itself is level and the tonearm counterweight is set correctly. See how to set turntable counterweight.

After adjusting, check both horizontal and vertical again. Recheck after a few days because the surface may settle. Also, if you move the turntable, repeat the process.

Common Leveling Mistakes

One common mistake is leveling only the platter but ignoring the tonearm. Even if the platter is perfectly horizontal, a tonearm that is not level will still cause azimuth and VTA errors. Always check both planes.

Another mistake is using a level that is too short to cover the platter. A short level may not show a slight tilt across the full diameter. Use the longest level that fits comfortably.

People sometimes forget to recheck leveling after changing the mat or the cartridge, since those components add weight and height. A heavier platter mat can compress the suspension and change the level. Similarly, swapping to a heavier cartridge might alter the tonearm's balance and require a new VTA setting.

What to pick for your use

Questions

Does an unlevel turntable really cause speed errors?

Yes. A tilted platter increases bearing friction and stresses the motor, which can lead to wow and flutter. Leveling keeps the platter rotating smoothly and speed stable. The effect is more pronounced on direct-drive models, but belt-drive tables also suffer from added friction on the bearing.

Can I use a phone app as a level?

Some apps work, but a physical bubble level is more reliable because it doesn't rely on the phone's accelerometer, which may not be calibrated finely enough. If you use an app, calibrate it by placing the phone on a known flat surface and adjust the zero.

How often should I check leveling?

Check leveling whenever you move the turntable, change its surface, or notice any changes in sound. It's also wise to recheck after seasonal temperature shifts, as wood and furniture can expand or contract. A quick check every few months is good practice.

What if my turntable has no adjustable feet?

You can place thin, hard shims under the corners to level the platter. Paper or plastic shims work well. Avoid soft materials that compress unevenly. Ensure the surface itself is as level as possible. If the turntable has a suspended sub-chassis, you may need to adjust the suspension springs instead.

Does leveling affect audio quality?

Absolutely. Proper leveling prevents stylus misalignment and uneven wear, preserving high-frequency response and reducing distortion. It also keeps the vertical tracking angle accurate, which affects tonal balance. A level table also minimizes resonance and feedback, as the cartridge is not fighting gravity.
