TL;DR

The One-Line Answer

Place a small bubble level on the platter (not the plinth), and adjust the turntable's feet — or the surface beneath it — until the bubble is centered on both the left-right and front-back axes.

Why Leveling Actually Matters

A turntable that sits even slightly off-level behaves differently than one that doesn't. The tonearm is a finely balanced pendulum on low-friction bearings, and tilting the pivot shifts the forces acting on the stylus. According to U-Turn Audio's setup guidance, an unlevel surface creates excess horizontal force that increases bearing friction and can cause tracking issues like distortion and skipping.

The most immediate casualty is tracking force distribution. When a deck tilts, a component of the stylus weight pushes the tonearm toward the low side, so one groove wall sees more pressure than the other — which translates into uneven stylus wear.

Anti-Skate and VTA Drift

Anti-skate is the second casualty. It's calibrated to cancel a specific sideways pull assuming the platter is flat; tilt the deck and anti-skate is now working against different geometry. Victrola's anti-skating guide notes that anti-skate keeps the stylus centered for clean stereo separation — a tilted deck undermines that calibration. Vertical tracking angle (VTA) also drifts subtly front-to-back, because the pivot height is no longer what the designer intended.

What You Need

Leveling requires little equipment. The core tool is a small bubble level (spirit level) — some turntables include one built into the plinth; most do not. The simplest option is a dedicated circular level: Ortofon's Libelle is a widely used example, a 4cm circular spirit level meant to sit on the platter, also listed by Turntable Lab as a standard accessory. Any small flat-bottomed bubble level works; a short torpedo level from a hardware store does the job if placed carefully.

Adjustable Feet — and When You Don't Have Them

The second ingredient is a way to adjust the deck's height at each corner. Most modern turntables ship with height-adjustable feet that thread up or down. The Absolute Sound's review of the Pro-Ject Debut Carbon EVO notes the EVO's adjustable feet make leveling "as easy as placing a bubble on the platter," and World Wide Stereo points out it uses three feet rather than four, which simplifies leveling.

Not every deck works this way. Rega's Planar series is shipped with non-adjustable feet as a deliberate design choice — the plinth is meant to rest as a fixed three-point structure, with the surface beneath it leveled instead.

Step-by-Step: How to Level the Deck

Start with the turntable fully assembled, the platter installed, and the deck sitting on its intended shelf. Remove anything that doesn't belong on the platter — no record, no clamp, no loose slipmat. The bubble level goes directly on the platter surface, ideally near the spindle.

Check the left-right axis first. Place the level so its reference line runs from one side of the plinth to the other. If the bubble is off-center, adjust the feet on the low side upward (or the high side downward) in small increments until it's centered. Make quarter-turn adjustments at a time — leveling is sensitive, and large twists tend to overshoot.

Once left-right is dialed in, rotate the level 90 degrees and check front-back. Adjust again until this bubble is centered. The two axes can interact slightly on four-footed decks, so recheck left-right after front-back is set, and iterate until both are stable simultaneously.

Check the Platter, Not Just the Plinth

This is the single most common mistake in turntable leveling. The plinth is the outer chassis; the platter is the spinning disc on the bearing. What ultimately matters is that the record is level — which means the platter is level, not the plinth. On a well-assembled turntable the two should agree closely, but they don't always. A widely discussed thread on r/turntables reaches the conclusion most setup guides share: level the platter itself, as close to the spindle as possible, because that's where the record actually lives.

A Practical Check

Place the bubble level on the platter near the spindle, note the reading, then rotate the platter 180 degrees and read it again. If the bubble stays put, the platter is level. If it swings across as the platter turns, you're seeing bearing runout or a slightly dished platter — in which case, as discussed on Vinyl Engine's turntable forum, the practical approach is to level as best you can and accept that perfection isn't on offer. For the related task of dialing in tracking force, see how to balance a tonearm, which picks up exactly where leveling leaves off.

Common Misconceptions

Myth: "Close enough is fine — a little tilt won't affect anything."

Reality: even small tilts measurably shift the force balance on the stylus. A deck that looks flat to the eye can still be off by half a degree or more, and that's enough to bias tracking force toward one groove wall and throw off anti-skate. The effect is cumulative over thousands of revolutions and shows up as uneven stylus wear long before it shows up as audible distortion. If you have a bubble level, use it.

Myth: "You only need to level the turntable once."

Reality: floors shift with temperature and humidity, wooden stands settle over time, and rack feet compress under sustained load. Community discussion on the Naim Audio forum about Rega Planar setup highlights how owners routinely recheck level after moving the deck, adding components to the rack, or noticing seasonal floor movement. Leveling is a maintenance item, not a one-time chore — rechecking every few months or any time the deck or its support is disturbed is sensible practice.

If Your Turntable Has No Adjustable Feet

Rega is the most visible example. The logic is that the three-foot geometry is already optimized and introducing adjustable hardware risks coloring the sound — so leveling happens under the turntable rather than on it. The most common solution is to shim the shelf or stand so the surface itself is level. Thin, rigid shims work best: metal washers, hardboard slips, or purpose-made leveling feet for the rack. On the Naim community thread about the Planar 10, owners describe using drink coasters, metal shims, and adjustable isolation plinths; the consensus is to avoid anything compressible like foam or soft rubber, because a soft shim changes shape under load and drifts over time.

Aftermarket Feet and Dedicated Platforms

A second option is aftermarket adjustable feet. A writeup on lpturntables.blogspot.com describes the Michael Lim aluminum adjustable feet, which thread into the existing foot mounting holes and allow the stock rubber feet to be re-inserted on top. Whether to modify a Rega is a matter of taste — purists prefer to leave the deck stock and level the shelf instead. A third option is a dedicated isolation platform with its own adjustable feet, which solves leveling and isolation in one purchase.

Where Leveling Fits in the Setup Sequence

Leveling isn't the first step, and it isn't the last. A sensible sequence — covered in full in the complete turntable setup guide — runs roughly: unbox and assemble the deck, install and align the cartridge, level the turntable, balance the tonearm and set vertical tracking force, set anti-skate, and finally fine-tune VTA if the arm supports it.

Leveling comes before tracking force and anti-skate because both calibrations assume a flat platter. If you set VTF on a tilted deck and then level it afterward, your tracking force reading will shift. Cartridge installation itself can happen before leveling — it doesn't depend on it — but everything downstream of tonearm balance does.

It's easy to conflate leveling with isolation, because both involve what's under the turntable. Leveling is about static geometry — the platter being flat. Isolation is about dynamic vibration — keeping footfalls, speaker output, and structural resonance from reaching the stylus. A deck can be perfectly level and still suffer footfall skipping, or beautifully isolated but tilted. For the full picture, see turntable isolation explained.

Closing Thoughts

Leveling is the cheapest upgrade a vinyl setup will ever receive — a small bubble level and ten minutes of patience. It's also the first thing worth rechecking whenever a record starts skipping or a setup sounds subtly off.
