Hi Francesco, The label font and size of 3D labels can be controlled in Preferences (under Favorites menu), category: Background. This controls all 3D labels together -- they can't have different sizes. By "3D" I mean the labels that move along with the structure. If you use 2D Labels, you can control the size of each one separately, in the 2D Labels dialog. <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/2dlabels/2dlabels.h...> I hope this helps, Elaine ----- Elaine C.

Hello: Is it possible to increase the letter size of custom labels? I would like to show the residue number only, saving as a stereo pair. As my stereo pair (a protein complex) works nicely for most people only at a reduced size of the figure (14x4 centimeters, or even smaller), larger letter-size is needed for the labels.

thanks francesco pietra
