What size are you negatives?

For 5x7s I use 80mm for 35mm negs, 105mm for 6x6 negs.

35mm

For 35mm film, the standard enlarging lens is a 50mm.
BUT, for small prints, you have to lower the enlarger head rather far down, making it difficult to open the paper easel.
So just like a telephoto lens in reverse, a longer lens will let you position the enlarger head higher above the paper easel, so that you can open the paper easel.
Similar to @webestang64 , I use a 75 or 80mm lens.

When I was in high school and we were making even smaller prints, I think we used a 105 or 135 lens, for the same reason.
