Since this is a used Acme T-shirt, we don't have exact sizing information. However, the shirt is "unisex" and "adult" sized. To get a better idea, consider comparing the dimensions of a t-shirt you already own and that fits you well to the design dimensions of the Lithograph which is 9" height x 12" width. Note also that the shirt is described as "pre-shrunk", so it shouldn't shrink further. We recommend reading customer reviews (if available) for additional insights on fit.
