Most organizers are sized for standard U.S. letter paper (8.5 × 11 inches). Photo inserts and frames vary by product—examples include a 3.2 × 3.2 in insert and a 3 × 4 in frame—and some keepsake boxes are roughly 10 × 10 inches.
Many organizers are designed for display on shelves, dressers, or tabletops. Others fold for compact storage or are sized to sit on a desk. Expanding files and portable folders are often made to carry on the go or store neatly on a shelf.
