How to calculate it
Stitches per inch = fabric count ÷ threads crossed per stitch. Divide chart stitch dimensions by that rate for the stitched design size, then add twice the margin to each cut dimension.
Worked example
A 140 × 180-stitch chart on 14-count fabric worked over one produces a 10 × 12.86 in design. With 3 in margins, cut at least 16 × 18.86 in.
Before you cut or buy
- Aida is generally stitched over one; evenweave or linen may be worked over two threads. Set the over value accordingly.
- Check your finishing method: framing, hooping or sewing may require a larger margin.
Common questions
What does stitching over two threads mean?
On evenweave or linen, one cross may span two fabric threads. Enter 2 for threads crossed per stitch. On Aida, crosses commonly span one square, so enter 1.
How much fabric should I leave around a cross-stitch design?
A three-inch margin per side is a useful planning example, but your hoop, frame, finishing seam or framer may need more. Choose the margin for the intended finish.
Use your own measured materials and pattern instructions. Estimates cannot account for every variation in technique, shrinkage or layout.
