Inklingo files are PDFs (not software like Electric Quilt), so the layouts are not intended to be re-sized.
Some printers have software that allows you to re-size the layouts by a percentage, but that also re-sizes the seam allowances, which makes the sewing awkward (sometimes impossible). None of the suggested custom page sizes or yardage requirements would work either. I draw the shapes to a precise size, like 1.32 inch in the free Diamond Triangle Square shape collection.
Inklingo shapes are named with the finished size to make it easier. You can see all of the shapes that are available in the Index of Shapes under the Support & Goodies tab.
For example, if you want to make a 6 or 9 inch or 12 inch Star block, you can see some of the choices on the Main Stars Page under the Shop & Freebies tab.
There are several sizes of hexagons on the Main Hexagon Page.
