Aida count describes how many stitches fit in an inch when working one cross per square. The same chart therefore finishes smaller on a higher count, without changing its number of stitches.
Calculate the stitched area
Divide chart width by fabric count for width in inches, then repeat for height. A seventy-stitch-wide design measures five inches on fourteen-count fabric and about three point nine inches on eighteen-count fabric. This calculation describes the design area, not the fabric you should cut. The planner displays dimensions from the current grid and count so you can compare options before shopping.
Add usable margins
Add a margin to every edge for handling and finishing. A two-inch margin on each side adds four inches to the required width and height. Your hoop, frame, and finishing method may require a different allowance. Check the final cut dimensions against the fabric package; buying only the stitched area leaves no working edge. The app margin field is editable for this reason.
Consider the stitching experience
Higher count creates smaller crosses and can make detail appear more compact, but the holes and stitches may be harder to see. Try a small swatch with your lighting, needle, and intended strand count. Check coverage and comfort before committing to a larger piece. Fabric dimensions, color, and weave should also suit the finishing plan, not just the numerical design size.
Compare the displayed stitched size and cut size at fourteen and eighteen count before ordering fabric.

Our guides offer general planning advice. Chart colors are digital approximations. Choose physical floss from a real color card or your own stash before a large project. Fabric and thread estimates describe full crosses with your entered stitch length and allowance. Backstitch, half stitches, unusual carries, and finishing need separate planning. We do not claim hands-on tests of products mentioned in buying guides.
