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 × 0.74 in (25 × 19 mm) | Over 1.5 mm | 124 mm | 120 | Vinyl, card and thin sheet |
| 2 × 1.48 in (51 × 38 mm) | Over 3 mm | 248 mm | 35 | Any material, including 3 mm wood and acrylic |
| 3 × 2.23 in (76 × 57 mm) | Over 4.6 mm | 373 mm | 15 | Any material, including 3 mm wood and acrylic |
| 4 × 2.97 in (102 × 75 mm) | Over 6.1 mm | 497 mm | 6 | Any material, including 3 mm wood and acrylic |
| 6 × 4.45 in (152 × 113 mm) | Over 9.1 mm | 745 mm | 2 | Any material, including 3 mm wood and acrylic |
| 8 × 5.94 in (203 × 151 mm) | Over 12 mm | 994 mm | 1 | Any material, including 3 mm wood and acrylic |
| 12 × 8.9 in (305 × 226 mm) | Over 18 mm | 1,490 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.
