A3 Basket

An A3 basket is a storage container, typically made of plastic, metal, or wicker, sized to comfortably accommodate A3-sized paper and documents. The "A3" designation refers to a standardized paper size defined by the ISO 216 standard, measuring 297 x 420 millimeters (approximately 11.7 x 16.5 inches).

A3 baskets are commonly used in offices, classrooms, art studios, and homes for organizing and storing large-format papers such as blueprints, architectural drawings, artwork, posters, and large spreadsheets. They offer a convenient and accessible method for keeping A3 documents together and preventing them from being folded, crumpled, or lost.

The basket design typically allows for stacking, creating a vertical storage solution. They are often open-topped for easy access, but some may include lids for added protection against dust and damage. The material and construction of an A3 basket can vary depending on the intended use, ranging from lightweight plastic baskets for temporary storage to more durable metal baskets for long-term archiving.
