Graph Paper Sizes Explained: 1/4 in, 5 mm and More

Common square sizes

Graph paper is a grid of small squares, and the size of each square changes what the paper is good for. These are the sizes you will see most often.

• 1/4 in: often called quad ruled, with 4 squares per inch.
• 1/5 in: a little finer, with 5 squares per inch.
• 1/8 in: small squares for detailed work.
• 5 mm: a common metric size, close to 1/5 in.
• 1 cm: large squares that are easy to see and count.

Heavier lines every few squares

Many sheets draw a darker line every 4, 5 or 10 squares. These heavier lines let you count faster, because you can count blocks instead of single squares. Every 5 or 10 squares works well with metric sizes, and every 4 squares fits 1/4 in paper because it marks each inch.

Which size suits which job

Larger squares such as 1/4 in or 1 cm are comfortable for math homework and for graphs where you write numbers along the axes. Medium sizes such as 1/5 in or 5 mm suit floor plans and scale drawings, since you can set one square equal to a fixed distance.

Smaller squares such as 1/8 in work for sewing patterns, knitting and cross stitch charts, and pixel drawings, where each square is one stitch or pixel and you want many of them on one page.

Axes for plotting points

If you are plotting points or drawing a function, turn on the x and y axes. They give you a center to count from and make it clear where the four quadrants meet. For simple pixel art or planning, leave the axes off so the grid stays clean.

Choosing a size

Think about how much detail you need and how big your handwriting is. If you are unsure, start with 1/4 in or 5 mm and heavier lines every 5 squares. Print one test page, then switch to a different size on the graph paper page on this site if it feels too big or too small.
