Work out what sheet size to start from for a folded paper or card craft. Enter the finished width and height, the number of folds and the fold direction, and the tool gives the sheet size you need and a reminder of where to cut and fold. This is an approximate sizing helper, not a quote — paper thickness, grain and the fold style all affect the final size, so test on scrap first. All processing runs locally in your browser.

How to Use the Paper Cutting Size Calculator
Choose your units, enter the finished width and height, the number of folds and the fold direction. Press Calculate sheet to see the sheet size to start from and where to cut and fold.
What it accounts for
Each halving fold doubles the dimension of the sheet needed.
Width, height or both can be halved depending on your fold.
The result shows the finished size you should end up with.
Folding neatly
Score before folding and cut along the centre lines so edges line up. Card is thicker than paper, so add a millimetre or two. Treat the sheet size as an approximate guide, not a quote.

Results are approximate sizing guides, not a quote. Paper thickness, grain and fold style change the outcome, so test on scrap and adjust before cutting your final piece.
