This is a common problem with DS. We have found a fix to this issue and are currently converting all of our design files to include a Cricut version SVG that will import at the correct size ratio. Until all the designs are converted, you will need to resize your design within DS in order to have it be accurate to the original file. To get the exact size of the design, you will need to open the design in another graphic software program. You can download Inkscape for free at www.inkscape.org to use for proper sizing. Just open your SVG file there, select it and take note of the size. Go back and open your design in DS and change the size in your selector window and the design will now be the correct size. A quick test to check is if you have a design using ss10 sized rhinestones, ungroup the design and click on one of the circles. It should be anywhere between .126 and .130 width and height.
