Cross Stitch Aida Calculator: Finished Size in Inches or CM

Aida is the most common fabric for counted cross stitch, and its count decides how big your finished design turns out. Enter your pattern's stitch counts and fabric count below to see the stitched size instantly.

The same arithmetic also tells you how much fabric to cut, once you add margins for framing or hooping. The notes below explain what fabric count means, the formula behind the numbers, and how to check a fabric's count with the helper tool.

Aida finished-size calculator

Divides your stitch counts by the fabric count to give the finished stitched area.

How the size formula works

The finished size is your stitch count divided by the Aida count, once for the width and once for the height. Choosing centimeters converts the inch result by multiplying by 2.54. This is exact arithmetic, but it only covers the stitched area — margins for framing or hooping are your own choice and are handled by the fabric size calculator. The worked example further down shows the full arithmetic, including the cut with margins.

Limits: exact for labeled fabric; if the fabric stretched in storage, check its count with the helper below.

Check your Aida count

Count the squares across a measured length of fabric and this helper returns the count.

How the count check works

Fabric count is squares divided by inches. Lay a ruler flat on the fabric, count the squares along a measured length, and enter both numbers above — most Aida is labeled, but a quick check costs nothing.

Count over at least 2 inches: a single inch can mislead on fabric that has stretched or relaxed in storage. Check before you cut, especially with fabric bought loose or handed down from another stitcher, since a mislabeled cut ruins the whole size plan. If Aida was stored rolled tight, let it rest flat for an hour and count again. Unlike linen, where you count single threads, Aida's weave forms clear even squares that are easy to count.

What fabric count means

Fabric count tells you how many stitches fit into one inch of cloth. A 14-count piece of Aida holds 14 stitches per inch. Aida is woven with small blocks of thread that form visible squares, and each square holds exactly one cross stitch, so the count is simply squares per inch.

A higher count packs more stitches into the same inch, which makes every stitch smaller. The same pattern stitched on 18-count Aida finishes smaller and finer than it does on 11-count. Beginners usually start with 14-count because the squares are easy to see and most published patterns list finished sizes for it. Eleven-count gives chunky, bold stitches that are easy to hit, a common pick for children's projects or pieces meant to be read from across a room. Sixteen and 18-count suit detailed designs with crisp lines, but the smaller holes ask for good light and sometimes a magnifier. The count never changes the pattern itself — it only changes the size of the finished piece.

Planning the fabric cut

Finished size is only the stitched part of the project. A workable cut needs margins on all four sides: 3 inches per side leaves room for framing, while 2 inches per side suits a small piece that will live in a hoop. Add the margins to the finished size, so a 10 by 7.14 inch design with 3-inch margins needs a cut of about 16 by 13.5 inches.

Cut square to the grain so the edges run parallel to the weave; a skewed cut will fight you every time you mount the piece. If the design will be framed, confirm the frame's opening before cutting — framers need at least 2 inches of clean fabric past the stitching to wrap and mount it properly. Write the finished size and the cut size on a scrap of paper tucked into the project bag, so you never have to redo the arithmetic halfway through.

Worked example

Your pattern is 140 stitches wide and 100 stitches tall on 14-count Aida. Width: 140 ÷ 14 = 10 inches. Height: 100 ÷ 14 = 7.14 inches (about 25.4 cm by 18.14 cm). Add a 3-inch margin on each side: the exact cut is 16 by 13.14 inches, which rounds up to 16 by 13.5 inches — this site always rounds cuts up to the nearest half inch.

Same design on every Aida count

How a 140 × 100-stitch design finishes on standard Aida counts:

Fabric count	Finished size
11-count	12.73 × 9.09 in
14-count	10 × 7.14 in
16-count	8.75 × 6.25 in
18-count	7.78 × 5.56 in
20-count	7 × 5 in

Count-check example

You count 140 squares across 10 inches of fabric: 140 ÷ 10 = 14 stitches per inch, so it is 14-count fabric. Count over at least 2 inches for a reliable reading.

Frequently asked questions

Which Aida count is best for beginners?

Fourteen-count is the most common starting point because the squares are easy to see and most patterns list finished sizes for it. If the holes feel too small, 11-count gives chunkier stitches that are easier to hit. Good light matters more than the exact count you pick.

How much extra fabric should I leave around the design?

Leave 2 to 3 inches on every side. Three inches gives a framer room to mount the piece, while two inches suits a design that will sit in a hoop. Add the margins to the finished size, then round the cut up to the nearest half inch.

Can I change the fabric count after I start stitching?

Not on the same piece — the stitches you have already made are sized to the original count. You can restart the pattern on a different count, and only the finished size will change. The stitching itself looks the same.
