What is the proper format for expressing the dimensions of artwork?

The proper format for expressing the dimensions of artwork is Width: Height. This convention aligns with standard practices in art and design, where width is typically listed first to help convey the spatial arrangement of the piece. It provides a clear understanding of the artwork's proportions and facilitates easier communication among artists, galleries, and potential buyers.

This standard can often be seen in art catalogs, museum listings, and when discussing the dimensions in a general context, where sharing width first emphasizes the horizontal span before considering the vertical explanation. Being consistent in this practice ensures clarity in discussions related to display or framing of artworks.
