Measure each wall and read the actual roll’s width, length, pattern repeat and match rule before using the sheet. This planner makes full-height drops and labels them by wall-line.copy.strip. A cut list can be downloaded or printed with the measurements; keep those labels on the cut paper so that cutting order and hanging order stay distinct.

Roll area is only the starting point

A 10-meter roll that is 0.52 meters wide contains 5.2 square meters, not 10 square meters. Dividing wall area by that number still misses the way full-height drops fit along a roll. A wall 1.5 meters wide needs three 0.52-meter drops. At 2.8 meters high plus 0.2 meters of total trimming, each drop needs 3 meters before any pattern alignment loss.

The sheet rounds the width of each wall up to a whole number of drops. It does not deduct a window or doorway as though that area always becomes usable full-height paper. Separate walls restart at phase A. Continuing a pattern around corners, placing a focal motif and handling unusually high or sloping sections need a project-specific layout.

Choose the match on the label

Graham & Brown’s measuring guidance distinguishes free, straight and offset matching. Straight matching aligns adjacent strips horizontally. Its 64/32-centimeter offset example has a 64-centimeter repeat and a 32-centimeter offset.

This worksheet supports free match, straight match, or an offset of exactly half the repeat. It does not treat another offset as free match. For half-drop, A and B alternate across each wall, with B beginning half a repeat below A. Directions such as reverse hanging, mural panels or a different offset require a separate cutting plan.

Every roll is assumed to reach the same chosen A motif after the entered leader trim. Zero means the roll head is already there; the software cannot inspect the printed paper. Measure that discarded leader on the actual rolls, and check batch, repeat, direction and alignment before making any cuts. Adjacent drops also need a consistent top-trim portion of the total allowance.

Why the planner compares cutting orders

Consider three 3-meter drops with a 0.64-meter repeat on a 10-meter roll, no leader trim and half-drop matching. Hanging order is A, B, A. Cutting in that order uses starts of 0, 3.52 and 7.04 meters; the last drop cannot fit on the first roll.

Cutting A, A, B instead uses starts of 0, 3.2 and 6.72 meters, ending at 9.72 meters. All three drops fit one roll, provided their hanging labels are retained. The job sheet compares hanging order with phase groups sorted by longer drops first, reusing a roll’s remaining tail when the next labeled drop fits. It selects the lower roll count, then the smaller alignment loss.

These are two constructive plans, not an exhaustive search or a guaranteed minimum. The diagram distinguishes cut drops from leader, alignment loss and unused tails. The cut table records the start and end from the original roll head; the export also records each skipped length. Those unused lengths are not automatically assigned to small patches.

Use and keep the cut list

Choose the measurement system first: every US length is in inches, and every metric length is in meters. Switching the selector does not convert existing numbers. Enter decimal measurements, one wall per line, and the full pattern repeat rather than the half-drop offset. A third value repeats an identical wall as a fresh hanging sequence.

The planner handles at most 500 full-height drops and rejects a drop that cannot fit a fresh roll with its phase and allowances. It adds no universal waste percentage or spare roll. Extra matching stock is a separate reader decision based on the actual paper and project.
