Q: 6. What size Beseler lens do I need to enlarge to 11 x 14" BW prints?

A: The question would depend on the size of the negative you will be using to create the print, not the print size you wish to make. The height of your enlarger head will determine the size of the print you may create. Ideally, your enlarging lens' focal length should be equal to or greater than the diagonal of your film format measured in millimeters. (Back to high school math, you have to find the hypotenuse of your film; that a² + b² = c² equation, solving for c.) As an example, ​a 35mm negative measures 36x24mm in size. As such, the hypotenuse would be 43.27mm. So a 50mm enlarging lens (the next popular lens size above 43mm) would cover the full 35mm negative. For 120 6x4.5cm negatives, a 75mm lens (or larger) would be recommended. For 120 6x7cm negatives, a 105mm lens (or larger) would be recommended.​ An enlarging lens that is smaller than the diagonal of your film will allow you to crop in to a smaller area on your negative.
