6x8

The expansive 6x8 index card is one of the largest common sizes available. With dimensions of 6 inches wide and 8 inches high, it provides a generous 48 square inches of writing and drafting space. Sometimes referred to as the super-sized index card, this oversized card is well-suited for lengthy notes, detailed diagrams, extensive studying, and other applications where ample surface area is required. The 6x8 offers significantly more room than smaller 3x5 and 4x6 cards. While it may be less portable than smaller sizes, the 6x8's sizable dimensions are extremely useful when extensive writing, complex formulas, sizeable diagrams or artistic sketches need to be captured on an index card format. The origins of 6x8 cards can be traced back to large library catalog cards in the late 19th century. Today, it remains popular for scientists, artists, designers, students, and others who benefit from the expansive real estate the 6x8 card provides when portability is secondary. If big writing space is needed, the 6x8 delivers.
