How to Use This Calculator
- Enter the height and width of the parent sheet in millimeters.
- Select the grain direction: Grain Long (GL) if the grain runs parallel to the sheet's long dimension, or Grain Short (GS) otherwise.
- Enter the finished page height and width in millimeters.
- Read the number of leaves with correct grain orientation (grain parallel to the spine) — this is the preferred layout.
- Compare correct vs. wrong grain leaves to decide whether to rotate your imposition.
- Use the waste percentage output to optimize your sheet usage before ordering paper.
