33 vs. 45 RPM – What’s the Difference?
When playing vinyl records, you’ll often see 33 RPM and 45 RPM printed on the center labels. But what do these speeds mean, and when should you use each one? This guide explains the differences so you can pick the right setting for the best listening experience.
What does RPM mean?
RPM stands for revolutions per minute—the number of full spins your turntable makes in one minute.
- 33⅓ RPM: the standard speed for LPs (12 inch albums).
- 45 RPM: typically used for singles (7 inch) and many 12 inch maxi singles.
33 RPM – the standard for 12″ LP albums
Records played at 33 RPM are ideal for 12 inch LP albums, offering longer playtime per side—often up to about 20 minutes.
45 RPM – for maximum loudness
45 RPM is perfect when you want maximum impact and headroom, for example in club or DJ contexts.
- Shorter playtime—typically around 7–9 minutes per side on a 12 inch.
- Greater loudness and dynamic punch.
How do you choose the right speed?
- Check the center label or sleeve—it usually states “33 RPM” or “45 RPM”.
- 12 inch LP → usually 33 RPM.
- 7 inch single → usually 45 RPM.
- Some 12 inch maxi singles are cut at 45 RPM for higher loudness.
33 or 45 RPM — what suits you?
- Listening to a full album? Choose 33 RPM.
- Prefer loud, dynamic tracks and don’t mind a shorter side? Go with 45 RPM.
For custom advice, dubplates, or bespoke vinyl, pick the speed that matches your music and setup.
Conclusion
The difference between 33 RPM and 45 RPM comes down to a trade off between playtime and loudness. While 33 RPM suits longer albums, 45 RPM offers louder, more powerful playback.
