Will it cut at your size?
Scaling a design scales its thinnest part too. Here is this one at seven sizes, from 1 to 12 inches on its longer side, with how many copies fit a 12 × 12 inch sheet or mat.
| Size, width × height | Narrowest part | Cut length | Fit on a 12 in sheet | Rule of thumb |
|---|---|---|---|---|
| 0.6 × 1 in (15 × 25 mm) | 0.91 mm | 215 mm | 150 | Fine detail: vinyl and paper only, weed with care |
| 1.21 × 2 in (31 × 51 mm) | 1.8 mm | 429 mm | 40 | Vinyl, card and thin sheet |
| 1.81 × 3 in (46 × 76 mm) | 2.7 mm | 644 mm | 18 | Vinyl, card and thin sheet |
| 2.41 × 4 in (61 × 102 mm) | 3.7 mm | 859 mm | 8 | Any material, including 3 mm wood and acrylic |
| 3.62 × 6 in (92 × 152 mm) | 5.5 mm | 1,288 mm | 3 | Any material, including 3 mm wood and acrylic |
| 4.82 × 8 in (123 × 203 mm) | 7.3 mm | 1,717 mm | 2 | Any material, including 3 mm wood and acrylic |
| 7.24 × 12 in (184 × 305 mm) | 11 mm | 2,576 mm | 1 | Any material, including 3 mm wood and acrylic |
The narrowest part is the thinnest neck that holds the design together; sharp tips are not counted. For wood and acrylic, keep it at least as wide as the sheet is thick. How to open the file in Cricut, Silhouette and laser software.
