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 |
|---|---|---|---|---|
| 1 × 0.59 in (25 × 15 mm) | 1.3 mm | 228 mm | 150 | Vinyl, card and thin sheet |
| 2 × 1.18 in (51 × 30 mm) | 2.6 mm | 456 mm | 40 | Vinyl, card and thin sheet |
| 3 × 1.77 in (76 × 45 mm) | 4 mm | 684 mm | 18 | Any material, including 3 mm wood and acrylic |
| 4 × 2.36 in (102 × 60 mm) | 5.3 mm | 911 mm | 8 | Any material, including 3 mm wood and acrylic |
| 6 × 3.54 in (152 × 90 mm) | 7.9 mm | 1,367 mm | 3 | Any material, including 3 mm wood and acrylic |
| 8 × 4.72 in (203 × 120 mm) | 11 mm | 1,823 mm | 2 | Any material, including 3 mm wood and acrylic |
| 12 × 7.08 in (305 × 180 mm) | 16 mm | 2,734 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.
