Paper Quantity Calculator
Plan a batch without over- or under-buying: how many pieces come off each parent sheet, and how many sheets the whole run needs once waste is included.
Sheets to buy
From piece count to sheet count
Buying paper for a project is really two questions: how many of my piece fit on a sheet, and how many sheets does my target quantity take. The first is a packing problem the tool solves by trying both orientations; the second is arithmetic, padded by a spoilage allowance and rounded up.
The result also shows the yield and the spare pieces from the last sheet, so you know how much slack you have for re-dos.
Frequently Asked Questions
How many pieces fit on one sheet?
The calculator lays your piece out in a simple grid two ways — upright and rotated 90 degrees — and keeps whichever fits more. For example, a 105×148 mm card cuts four-up from an A4 sheet. It counts only whole pieces, since a part-piece at the edge is waste.
Why add a waste allowance?
Real projects lose paper to mis-cuts, test folds, jammed prints, and the odd ruined piece. A 5–15% cushion means you are not one spoiled sheet short at the end. The tool rounds the padded total up to whole sheets.
Does it account for grain or margins?
Not directly — it assumes edge-to-edge cutting. If your machine needs a gripper margin, or the grain must run a particular way, shrink the usable sheet size you enter accordingly and the count will stay honest.
Estimate only. It assumes a straight guillotine grid with no bleed or margin; adjust the usable sheet size for your own trimming needs.
