These are general guidelines as the length of music for each side is impacted by numerous variables including the content and dynamic range of the recorded music.
Please feel free to reach out and discuss the running times of your project and we will gladly provide audio counsel to ensure that your record is pressed at the right speed and sounds as good as it can.

Recommended Running Times

12” LP @ 33 1/3 RPM – 14-18 minutes per side is ideal and will provide a great sounding cut.
At 20 minutes and longer overall levels start to drop, surface noise will become more noticeable and bass may need to be trimmed. Sides over 24 minutes are possible but greatly compromise the final product.

12” LP @ 45 RPM – 12 minutes per side is optimal. For sides over 15 minutes, changing to 33 1/3 RPM might make sense.

10” @ 33 1/3 RPM – 12 – 13:30 Minutes per Side
10” @ 45 RPM – 9 – 10 Minutes per Side

7” @ 45 RPM – 3:30 is the optimal. Leading up to and after 4:30 level starts to drop a bit. Max recommend time is 5 minutes. Most cutting engineers recommend cutting a lower level at 45 RPM on 7 inch as opposed to doing a 7 inch at 33 1/3.

7” @ 33 1/3 RPM- Cutting at 33 1/3 on 7 inches is typically not recommend because of added distortion and some of the lowest cutting levels around – but it can be done up to 7 minutes per side.  Records will not sound good.
