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 | Smallest dot | Cut length | Fit on a 12 in sheet | Rule of thumb |
|---|---|---|---|---|
| 1 × 1 in (25 × 25 mm) | 0.28 mm | 734 mm | 100 | Too fine for most machines |
| 1.99 × 2 in (51 × 51 mm) | 0.56 mm | 1,468 mm | 25 | Fine detail: vinyl and paper only, weed with care |
| 2.99 × 3 in (76 × 76 mm) | 0.84 mm | 2,201 mm | 9 | Fine detail: vinyl and paper only, weed with care |
| 3.99 × 4 in (101 × 102 mm) | 1.1 mm | 2,935 mm | 4 | Vinyl, card and thin sheet |
| 5.98 × 6 in (152 × 152 mm) | 1.7 mm | 4,403 mm | 1 | Vinyl, card and thin sheet |
| 7.98 × 8 in (203 × 203 mm) | 2.2 mm | 5,870 mm | 1 | Vinyl, card and thin sheet |
| 11.96 × 12 in (304 × 305 mm) | 3.4 mm | 8,806 mm | 1 | Any material, including 3 mm wood and acrylic |
The smallest dot 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.
