Half drop waste on a short wall: why the leftover grows
A half-drop pattern shifts every other strip. On a short wall that shift can cost you an extra cut from the same roll.

Answer: Enter wall height, roll width, and half drop. The plan shows how many strips and how much pattern match length you lose before you buy another roll.

Straight match repeats the motif at the same height on every strip. Half drop offsets every other strip by half the pattern repeat, so vertical waste is not the same on odd and even strips.
On a short wall the offset still applies. You may finish the width with strips to spare horizontally, yet still burn length vertically because each pair of strips needs matching points.
Use the leftover roll figure as a plan, not a guarantee. Print the cut list at 100% scale and dry-fit the first two strips before you commit the whole roll.
