Make boxes and paper templates to your own size

Choose a box, mailer, tray, envelope, or paper model; enter the finished measurements; then download true-size cut and fold files.

Start with what you want to make

How sizing works

For ordinary boxes, you can enter the space inside, the size outside, or the product size plus room around it. Shapes such as cones and stars show the measurements that actually define that model. Everything is calculated in millimeters and exported at full size.

Files for common hobby machines

Download SVG, Cricut SVG, layered LightBurn SVG, SignCut-ready SVG, DXF, full-size PDF, tiled PDF, PNG, JPEG, the saved recipe, a build report, and a printable assembly guide. The tiled PDF includes page labels, registration crosses, and a 50 mm ruler so you can check print scale.

Measure your material first

Card, chipboard, and corrugated board fold differently. Enter measured thickness, kerf, fold take-up, and lid or lock clearance. If you have not measured them yet, KerfCanvas still makes the template and shows a warning; it never pretends an untested material profile is proven.
