Vinyl Anti-Skating Explained: A Guide

If your turntable has an anti-skate dial, hanging weight, or tiny bias slider, it can feel like one of those adjustments designed mostly to intimidate new vinyl listeners. It is not. Anti-skating is simply the turntable's way of helping the stylus sit evenly in the record groove while the record spins. Set it close enough and you get cleaner inner grooves, better stereo balance, and less uneven wear.

That matters because vinyl is no longer a tiny hobby. The RIAA reported that U.S. vinyl revenue grew 7% to $1.4 billion in 2024, the format's eighteenth straight year of growth, and vinyl albums outsold CDs by units for the third year in a row, 44 million to 33 million. If collectors are putting that much money into records, setup basics like tracking force and anti-skate deserve attention. RIAA 2024 Year-End Revenue Report.

What anti-skating actually does

When a pivoted tonearm plays a record, friction between the stylus and groove acts along the direction of record rotation. Because the arm is angled and anchored at a pivot, that friction creates a side force that tends to pull the arm inward, toward the spindle. Audio-Technica describes anti-skate as a small outward force that counteracts that inward tendency as the tonearm approaches the center of the record. Audio-Technica.

The goal is not to freeze the tonearm. It is to reduce unequal pressure on the two groove walls. Stereo records store left and right channel information in the two walls of a V-shaped groove. If the stylus is pressed harder against one wall, you may hear channel imbalance, grainy treble, or distortion on vocal sibilance. Over long use, that imbalance can also contribute to uneven stylus and groove wear.

Why the inner grooves reveal the problem

Anti-skate problems often show up near the end of a side. The inner grooves have less linear speed under the stylus than the outer grooves, so dense music near the label gives the cartridge less physical space to trace the same information. A loud vocal, hot cymbal, or busy guitar part can expose setup flaws that seemed invisible during track one.

Not every bit of inner groove distortion is an anti-skate issue. Cartridge alignment, stylus wear, dirty records, damaged grooves, and too little tracking force can all cause similar symptoms. Still, anti-skate is an early check because it is easy to adjust and easy to reverse. Audio-Technica recommends listening to the final minutes of a record for sibilance that is louder in one channel, then adjusting until distortion is minimized.

The simple starting point: match tracking force

For most consumer turntables with a calibrated dial, the sane starting point is to set anti-skate to the same number as vertical tracking force. If your cartridge tracks at 2.0 grams, start with anti-skate at 2. Audio-Technica gives that rule for adjustable turntables, and its tonearm setup guide uses the AT-VM95E as an example cartridge with a 2.0 gram tracking force. Audio-Technica tonearm setup guide.

Some turntables use a hanging weight instead of a dial. Pro-Ject-style arms, for example, often place a thread loop on a specific notch that corresponds to downforce. Others, especially beginner models with integrated cartridges, hide anti-skate inside the tonearm assembly. If there is no user control, the manufacturer may have preset it for the supplied cartridge.

Why the number is only a starting point

The physics is messier than a dial marking suggests. Stereophile's Jim Austin explains that skating force starts with groove friction, but the inward pull comes from the mismatch between the tangent of the groove and the line from stylus to tonearm pivot. That relationship changes across the record. Friction also changes with groove modulation, stylus shape, record condition, and even different pressings of the same album. Stereophile.

A technical paper on skating force notes that friction coefficient values measured for a Shibata stylus at 1.5 grams ranged from 0.22 to 0.64, depending on factors such as record material, dirt, groove damage, modulation, surface roughness, and diamond condition. That wide range explains why two similar systems can need slightly different final settings. Skating force and antiskating.

How to fine tune anti-skate by ear

1. Level the turntable. A tilted plinth can make any tonearm adjustment misleading.
2. Set tracking force first. Balance the arm, set the counterweight, and use the cartridge manufacturer's recommended range.
3. Start with the matching value. If VTF is 1.8 grams, start anti-skate around 1.8.
4. Play a familiar, clean record. Choose a side with vocals or bright instruments near the end.
5. Listen for one-channel stress. If sibilance leans to one side, make small changes and replay the same passage.
6. Check more than one radius. Listen near the beginning, middle, and end. You are aiming for the best average, not perfection at every groove.

Test records can help, but they are not magic. Ortofon's Test Record includes tracking ability bands from 50 to 100 micrometers and tells users to set vertical tracking force and anti-skating according to the cartridge's recommended technical data before testing. It is useful for repeatable checks, especially if you change cartridges often, but your real records still matter because music creates changing groove modulation. Ortofon Test Record.

Common mistakes collectors make

The biggest mistake is using anti-skate to compensate for the wrong problem. If the cartridge is badly aligned, the stylus is worn, or tracking force is below spec, cranking the dial will not save the sound. Another mistake is setting anti-skate to zero because someone heard DJs do it. Some DJ setups reduce anti-skate for scratching and back-cueing, but home listening has different priorities: stable tracking, channel balance, and low wear.

If you track your listening with What's Spinning, setup changes become easier to judge over time. Play a few familiar albums after an adjustment and note whether the same end-of-side passages stay clean. The app can keep the listening history while your ears do the final call.

FAQ

Should anti-skate always equal tracking force?

No, but it is the best starting point on many turntables. Match the dial to your vertical tracking force first, then fine tune by listening for distortion, sibilance, and channel imbalance on familiar records.

What happens if anti-skate is too low?

The inward skating force can press the stylus harder against one groove wall. You may hear mistracking, inner groove distortion, or one channel sounding dirtier than the other, especially near the end of a side.

Can too much anti-skate damage records?

Extreme settings are not good for wear because they push the stylus unevenly in the opposite direction. Small overcorrections are usually heard as channel imbalance or distortion first, so adjust in small steps.

Do entry-level turntables need anti-skate adjustment?

Many entry-level models have fixed, factory-set anti-skate designed for the built-in cartridge. If there is no control, focus on a clean stylus, clean records, timely stylus replacement, and a level surface.
