How the Pattern Enlargement Percentage Calculator works
Scale % = desired measurement ÷ original measurement × 100. Every dimension scales by the same factor, and the area changes by its square. Use the same unit for all three inputs. Enter 100 percent as no change, and copiers that stop at 200 percent need two passes for larger jumps. Example: with Original measurement 8, Desired measurement 12, and Other dimension (original) 5, the result is Copier scale = 150%; Other dimension after scaling = 7.5; Multiplier = 1.5.
