An A4 size notebook measures 8.27 inches by 11.69 inches (210mm x 297mm). A4 size is the most popular standard paper size used all around the world in countries that follow the ISO 216 standard. It is used for a wide variety of paper formats, including printing documents, documents created using desktop publishing software and other documents. The A4 is the standard size for office documents, such as letterheads, faxes, memos and reports, as well as most printed materials such as flyers, brochures and catalogues.
A4 size notebooks come in many different styles, shapes, and covers. Depending on the brand, you may find A4 size notebooks with different covers, such as soft or hardbound covers. You may also find notebooks with a pocket on the inside or compartment/organizer inside the back cover.
When buying an A4 size notebook, it is important to check the dimensions so you know it will comfortably fit any documents or items you want to store in it. It is also a good idea to check the type of paper the notebook is made of; thick paper will prevent any bleed-through from fountain pens or excessive marker saturation. Many A4 size notebooks also feature perforated pages for easy and neat removal of important documents or papers.
