The success of smaller cuts made by a Silhouette cutting machine is dependent on: 

  1. Design intricacy 
  2. Material type in use

Design Intricacy

While you may be able to cut a basic block-type font on a scale of a quarter inch, a more detailed font with serifs (curves and details around the tips of the letters) may not cut as well. 

Material Type

The level of success would also depend on the material type in use. While you may cut more detailed or intricate images on a smaller scale on thinner materials (such as vinyl for example), you would not be able to achieve the same scale and intricacy with a thicker material (such as cardstock). As the scale of an image is lowered and the intricacy increases and/or material thickness increases, the resulting quality of cut may be lowered.
