How the sheet yield is calculated
Usable width and height are reduced by the selected margins. Whole labels are then fitted with the requested inter-label gaps. The same calculation is repeated after rotating each label by 90 degrees.
columns = floor((usable width + horizontal gap) ÷ (label width + horizontal gap))
rows = floor((usable height + vertical gap) ÷ (label height + vertical gap))
labels per sheet = columns × rows
rows = floor((usable height + vertical gap) ÷ (label height + vertical gap))
labels per sheet = columns × rows
Production note
This is a geometric layout estimate. Real presses and cutters may require gripper margins, registration marks, bleed, gutters or finishing clearance larger than the simple margins entered here.
