1/2 Inch Graph Paper

Two cells equal one inch. For any 1:24 architectural drawing, one cell is one foot of real-world space. A typical 12 × 14 ft room fits in a 12 × 14 cell rectangle, leaving plenty of paper around it for labels and dimensions.

Use it as a built-in scale ruler

Half-inch cells are spacious enough to act as little labelled boxes. For furniture layouts, write 'sofa', 'desk', or dimensions directly inside the cell rather than off to the side with arrows.

Write notes inside cells, not over them

With only 16 × 20 usable cells, you have almost no resolution for plotting curves or scatter points. For anything quantitative, drop to [1/4 inch](/graph-paper/graph-paper-quarter-inch) or [5 mm](/graph-paper/graph-paper-5mm).

Don't try to plot data on it

The cells are big enough that a 0.5 mm pen looks lost inside them. Crayons, marker tips and chunky pencils suit this grid better than fine liners.
