The 18x24" frame is one of the most popular choices for posters, gallery prints, and statement pieces. With its generous dimensions and dual matting options, it’s also incredibly flexible. Whether you're displaying a full 18x24 piece or adding a mat for 16x20 or 12x18 artwork, this guide covers all your layout options — including compatible larger frames.
