Vinyl records come in three main speeds: 33 1/3 RPM, 45 RPM, and 78 RPM. Knowing the RPM of your record is important because it ensures that you are playing it at the correct speed. If you play a record at the wrong speed, it will sound distorted.
Here are the different ways to know what RPM your record is:
- Look at the label: The RPM of your record will usually be printed on the label, near the center hole.
- Measure the diameter of the hole: The diameter of the hole in the center of a record can tell you its RPM. A 33 1/3 RPM record will have a hole with a diameter of about 1.25 inches. A 45 RPM record will have a hole with a diameter of about 0.75 inches. A 78 RPM record will have a hole with a diameter of about 0.5 inches.
- Listen to the record: If you are unsure about the RPM of your record, you can listen to it. A 33 1/3 RPM record will play for about 20 minutes per side. A 45 RPM record will play for about 5 minutes per side. A 78 RPM record will play for about 2 minutes per side.
Here is a table summarizing the characteristics of different types of vinyl records:
| Type of Record | RPM | Diameter of Hole | Playing Time per Side |
|---|---|---|---|
| 33 1/3 RPM | 33.333 RPM | 1.25 inches | About 20 minutes |
| 45 RPM | 45 RPM | 0.75 inches | About 5 minutes |
| 78 RPM | 78 RPM | 0.5 inches | About 2 minutes |
Conclusion:
Once you know the RPM of your record, you can set your turntable to the correct speed. This will ensure that you are getting the best possible sound quality from your records.
