Grid paper is a type of writing paper that features a printed grid of fine lines, creating squares or rectangles. This grid helps users maintain straight lines and consistent spacing, making it ideal for drawing, drafting, and mathematical calculations. It is commonly used by students, architects, and artists. The grid can vary in size, with some papers having larger squares for sketching and others with smaller squares for precise work. Grid paper is often used in conjunction with tools like rulers and compasses to create accurate diagrams and designs.
