Garamond and Bodoni are serif fonts while Helvetica and Futura are san serifs. The san serifs seem to be more legible at the size of the tracing. All the fonts have about the same x-height and width, making them all relatively imposing. In addition, the fonts are all relatively modern noted by the straight lines with the serifs perhaps being a tad more organic. Bodoni especially has a lot of contrast between the thick and thin in each of the letters especially at the terminals, finials, etc while Helvetica and Futura are generally uniform. The angle of stress for Garamond and Bodoni seems to be leaning towards the left. Lastly, even though Futura doesn’t have a lot of changes in thickness, the sharp ends of capital letters do give a sense of contrast.
