The question is: does Chimera know they have different pixel sizes?
(How do you know that they have different pixel sizes.... is it set or reported in Relion?)
To check or adjust pixel size of maps in Chimera, use Volume Viewer menu "Features... Coordinates" to show map Coordinates settings in the Volume Viewer dialog. These include Voxel size. You can see the current values and optionally enter different ones to change them.
...and its Coordinates settings:
I hope this helps,

All of these maps are different in pixel size and box size, however they display as the same size in Chimera, with the same size outline box. The voxel size in volume viewer is correct according to the pixel size I designated in Relion_image_handler. I assumed that these maps would be different in size since they have different pixel sizes and box sizes.
