Setting up your studio monitors are one of the most important things you will ever do when setting up your music studio (recording, mixing and mastering studio). Being able to hear correctly and interpret the correct sounds are of most importance. This is why you need to adhere to the strict guidelines of setting up your studio monitors.
The Perfect Triangle
In a nut shell, your head, that big round thing that holds your ears, and the 2 monitors need to make a triangle. Each side of the triangle needs to be of equal distance and the distance from each side should be 3 feet, give or take, depending on the size of your studio monitors and what works in regards the ergonomics you require. You may have to adjust them a bit, to get the very best and optimal sound for your room. Room acoustics are very funny and unpredictable at times.
Some side notes:
The center of the triangle should be as close to center to both walls on the left and right side of them.
The studio monitors should not be up against the back wall. The wall you look at when sitting at your workstation.
