Playing a record at the wrong speed is one of the most common beginner mistakes. The music sounds too high-pitched or too low, and you might think your turntable is broken. In reality, you just need to switch the speed setting.

Vinyl records come in two main speeds: 33 1/3 RPM and 45 RPM. Knowing which one to use is simple once you know what to look for. This guide walks you through the steps to identify the correct speed and get the best sound from your collection.

Why Vinyl Speed Matters

The speed at which a record spins determines how fast the stylus travels through the grooves. If the speed is too slow, the music sounds sluggish and lower in pitch. If it's too fast, everything sounds chipmunk-like and rushed. Correct speed is essential for enjoying the music as the artist intended.

33 1/3 RPM is the standard for full-length albums (LPs), while 45 RPM is typically used for singles and some audiophile pressings. Many modern reissues and box sets include 45 RPM pressings for better sound quality, so you can't always assume a 12-inch record is 33 1/3 RPM.

• Check the record label or sleeve for the RPM marking.
• Look at the size: 7-inch records are almost always 45 RPM.
• Listen for pitch: if vocals sound too high or too low, switch speeds.

Step-by-Step: Identify the Correct Speed

Follow these steps to determine the correct speed for any vinyl record before you drop the needle. With practice, you'll be able to tell within seconds.

Start by examining the record itself. The label in the center usually states the speed, but sometimes it's only on the outer sleeve. If you can't find it, use the physical clues and listening test below.

• Always clean the record before playing to avoid dust affecting the pitch.

Common Mistakes to Avoid

One common mistake is assuming that all 12-inch records are 33 1/3 RPM. Some 12-inch singles and audiophile reissues are pressed at 45 RPM for better fidelity. Another mistake is ignoring the pitch test: if the music sounds even slightly off, it's worth trying the other speed.

Also, remember that some turntables have a pitch control slider. If it's not set to zero, the speed will be wrong even if you select the correct RPM. Always check that the pitch control is centered.

• Set your turntable's pitch control to zero before playing.
• When in doubt, try 45 RPM first for 7-inch records.

How to Set the Correct Speed: Step-by-Step

1. Check the record label: Look at the center label of the record. Most labels print the speed (e.g., '33 1/3 RPM' or '45 RPM') near the catalog number. If it's not there, check the outer sleeve or inner sleeve. If you find the number, set your turntable to match.
2. Inspect the record size and grooves: 7-inch records are almost always 45 RPM. 12-inch records are usually 33 1/3, but some singles and audiophile pressings are 45. If the grooves are tightly packed and the record feels heavy, it might be a 45 RPM pressing. When in doubt, try the 45 RPM setting on a 7-inch record.
3. Listen for pitch and adjust: Play the record and listen to a familiar section. If the vocals sound too high or the music seems rushed, switch to the other speed. If the music sounds too low and sluggish, you're playing too slow. Trust your ears: the correct speed should sound natural and musical.
