How the cross stitch size calculator works out finished size
A cross stitch chart is measured in stitches, but the fabric decides how big each stitch is. Aida fabric is woven into a grid of holes, and its count is the number of squares per inch. On 14-count Aida, 14 stitches fill one inch. Evenweave and linen are counted in threads, and you normally stitch over two threads, so 28-count evenweave also gives 14 stitches per inch. The finished size is simply:
finished inches = stitches ÷ stitches per inch, and finished cm = finished inches × 2.54
That is all this calculator does, for both directions, plus the margin you need around the design. It shows every number so you can check the arithmetic yourself, and it remembers your fabric and margin on this device.
Fabric count comparison
The same chart changes size a lot between fabrics. This table shows finished width × height in inches for common chart sizes. Use it to decide whether a design you like will suit the space you have, or whether to move to a finer fabric.
| Stitches | 11 | 14 | 16 | 18 | 25 over 2 | 28 over 2 | 32 over 2 | 36 over 2 |
|---|---|---|---|---|---|---|---|---|
| 50 × 50 | 4.5 × 4.5 | 3.6 × 3.6 | 3.1 × 3.1 | 2.8 × 2.8 | 4.0 × 4.0 | 3.6 × 3.6 | 3.1 × 3.1 | 2.8 × 2.8 |
| 100 × 100 | 9.1 × 9.1 | 7.1 × 7.1 | 6.3 × 6.3 | 5.6 × 5.6 | 8.0 × 8.0 | 7.1 × 7.1 | 6.3 × 6.3 | 5.6 × 5.6 |
| 150 × 100 | 13.6 × 9.1 | 10.7 × 7.1 | 9.4 × 6.3 | 8.3 × 5.6 | 12.0 × 8.0 | 10.7 × 7.1 | 9.4 × 6.3 | 8.3 × 5.6 |
| 200 × 150 | 18.2 × 13.6 | 14.3 × 10.7 | 12.5 × 9.4 | 11.1 × 8.3 | 16.0 × 12.0 | 14.3 × 10.7 | 12.5 × 9.4 | 11.1 × 8.3 |
Notice that 14-count Aida and 28-count evenweave over two give identical sizes, as do 16 and 32, and 18 and 36. Choosing between them is about look and feel rather than size: evenweave and linen give a softer, more traditional finish, while Aida's clear holes are easier for beginners and for anyone with tired eyes.
How much fabric to cut
Always cut more fabric than the design. You need room to hold the fabric in a hoop or on scroll bars while you stitch, and room to fold or lace the edges when you frame it. The common rule is 3 inches on every side, which adds 6 inches to each dimension. The calculator rounds the cut size up to the next half inch (or whole centimeter) so it matches how fabric is sold and cut.
- 2 inches per side is enough for cards, small ornaments and patches that will be trimmed.
- 3 inches per side suits most framed pictures and hoop displays.
- 4 inches or more is safer for big pieces that will be stretched over board or professionally framed.
If you are finishing the piece in a hoop, the hoop needs its own margin inside the ring. The hoop size calculator works out which hoop or ornament frame holds a design, and the largest design a hoop you already own can take.
Working backwards from a size you want
Have a frame, a cushion or a space on the wall already? Switch to "Size → stitches", enter the finished width and height, and pick a fabric. The calculator multiplies by stitches per inch and rounds down, so the design never ends up bigger than the space. Then open the pattern maker and use that width; it keeps the shape of your picture and works out the height for you.
Stitch counts also tell you how much work a design is. A 140 × 100 chart is 14,000 squares if it is fully stitched. At a typical 60 to 120 stitches an hour, that is roughly 115 to 235 hours. The time calculator turns your own pace into a finish date, and the floss calculator works out how many skeins of each color to buy.
Measuring your own fabric
Fabric counts are nominal. Some Aida is a fraction off its label, and many evenweaves have slightly different thread counts across the width and the length. For a design that has to fit an exact frame, lay a ruler on your fabric, count the squares or threads in 2 inches, and divide by two. If your "14-count" measures 13.6, a 140-stitch design will come out about 10.3 inches rather than 10, so give yourself a little more margin.
Example results
Sampler on 14-count
140 × 100 stitches on 14-count Aida: 10.0 × 7.1 in (25.4 × 18.1 cm). Cut 16 × 13.5 in with 3 in margins.
Same chart on 28 over 2
140 × 100 stitches on 28-count evenweave over two: also 10.0 × 7.1 in, because 28 over 2 is 14 stitches per inch.
Reverse: 8 × 10 in frame
An 8 × 10 in opening on 16-count Aida holds up to 128 × 160 stitches.
