Aida count & finished size calculator

Enter a chart's stitch count and your fabric to get the finished size, the fabric you need to buy, and the total number of stitches.

The arithmetic

Fabric count is the number of stitches per inch, so the finished size is a single division:

  • width in inches = chart stitches wide ÷ fabric count
  • height in inches = chart stitches tall ÷ fabric count
  • centimetres = inches × 2.54

Higher count means smaller stitches, so the same chart comes out smaller on higher-count fabric. Evenweave and linen are usually stitched over two threads, which halves the effective count - 28-count over two gives 14 stitches per inch, the same size as 14-count Aida.

Fabric size is not finished size. Add margin on all four sides for the hoop and for framing: 2 inches per side is the minimum, 3 inches is what most framers prefer, and 4 inches suits a large piece on stretcher bars.

Quick reference: finished width in inches

Choosing a count

  • 11-count - large stitches, easy on the eyes, uses more thread.
  • 14-count - the default almost every chart assumes.
  • 16-count - finer, with little extra strain; good for fitting a big photo chart into a sensible frame.
  • 18-count and finer - best detail for portraits, hardest on eyesight.

If a chart comes out larger than the wall space you have, move up a fabric count rather than shrinking the chart - a finer fabric keeps every stitch and simply makes them smaller.
