Use this form to compute the best combination of rows and columns to preserve the overall aspect ratio of your chosen pattern. The pattern size will grow and shrink with the changes in number of rows and columns in order to have uniform patterns from first to last row. Fill in the size of the quilt and the pattern width and height from your long arm screen. Use the default spacing between rows and all borders or enter your own values in inches to the nearest hundreth of an inch (e.g. 5.67).
