I guess you mean measuring the size of an atomic structure, such as from the Protein Databank. Given such a structure, you can do distance measurements between any two atoms. Or, with command "measure inertia" you can calculate an inertial ellipsoid for the protein, which reports the three axis lengths.<br>
<br>
See the "measurements" page and links therein for how to do many types of measurements in ChimeraX:<br>

I hope this helps,<br>
