How fine is it at your size?
Scaling a design scales its finest detail 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 × 0.87 in (25 × 22 mm) | 0.79 mm | 325 mm | 110 | Fine detail: vinyl and paper only, weed with care |
| 2 × 1.73 in (51 × 44 mm) | 1.6 mm | 650 mm | 30 | Vinyl, card and thin sheet |
| 3 × 2.6 in (76 × 66 mm) | 2.4 mm | 975 mm | 12 | Vinyl, card and thin sheet |
| 4 × 3.46 in (102 × 88 mm) | 3.1 mm | 1,299 mm | 6 | Any material, including 3 mm wood and acrylic |
| 6 × 5.2 in (152 × 132 mm) | 4.7 mm | 1,949 mm | 2 | Any material, including 3 mm wood and acrylic |
| 8 × 6.93 in (203 × 176 mm) | 6.3 mm | 2,599 mm | 1 | Any material, including 3 mm wood and acrylic |
| 12 × 10.39 in (305 × 264 mm) | 9.4 mm | 3,898 mm | 1 | Any material, including 3 mm wood and acrylic |
The narrowest part is the finest detail in the pattern. Below about half a millimetre it is too small to cut and may fill in when printed. How to open the file in Cricut, Silhouette and laser software.
