As others have said - it depends on the shape of the mouth/head. Some horses are totally comfy in a big, fat bit others won't be able to close their mouths comfortably and you'll get a lot of fussing with the bit and general grumpy chomping for your troubles. If you can, just experiment with different widths and get an idea of what your horse likes and what is too much. Generally, I don't go with bits that are a whole lot thicker than my thumbs.
