What size negative are you printing?

- 6x9 format 120: 105mm
Using a shorter focal length will give you greater enlargement. If you can't get the elevation with a normal lens to fill your paper, switch to the shorter focal length. Be advised, though, that you may experience vignetting towards the edges of the negative as a result. Depends on the lens.
