Cross Stitch Fabric Calculator: Size Your Cloth by Hand

You have a chart. Now you need cloth, and you do not want to cut it too small. Too small is the worse mistake, since you cannot add fabric back.

A cross stitch fabric calculator solves this in one step. But the sums are simple, and doing them once by hand shows you why the answer is what it is. We worked through a real chart, then built the table for six fabrics.

What is the cross stitch fabric calculator formula?

Two lines. For each side of the design:

Design size in inches = stitches on that side divided by stitches per inch

Cut size in inches = design size plus 2 times your margin

That is all a cross stitch fabric calculator does. The only trick is the first line, which depends on the count. DMC explains count this way:

"The “count” of aida refers to the number of stitches you make in an inch. So, the higher the count the smaller the stitches. We recommend beginners use 14-count aida."

So 14-count Aida gives 14 stitches per inch. A higher count packs more stitches into an inch, and the design comes out smaller.

A worked example

Our test chart is a detail from Hokusai's wave print, charted at 120 stitches wide and 25 colors. The converter gave us a 120 x 83 grid. That is 9,960 stitches.

Let's size it for 14-count Aida.

1. Width: 120 divided by 14 is 8.57, which rounds to 8.6 inches.
2. Height: 83 divided by 14 is 5.93, which rounds to 5.9 inches.
3. Add a 3 inch margin on every side. That is 6 inches on each dimension: 8.6 plus 6 is 14.6, and 5.9 plus 6 is 11.9.

Cut a piece 14.6 x 11.9 inches. Done.

The tool agrees. Its answer for this chart is a design of 8.6 x 5.9 inches and a cut of 14.6 x 11.9 inches. All figures here are from the Threadhood converter, run on 3 November 2026.

How much fabric do I need for a cross stitch?

It depends on three things: the stitch count, the fabric and the margin. Here is the same wave chart on all six fabrics we support, each with 2, 3 and 4 inch margins.

Table 1. Design and cut sizes in inches for the 120 x 83 wave chart. Figures from the Threadhood converter, run on 3 November 2026.

The same chart ranges from 6.7 inches wide on 18-count to 10.9 inches on 11-count. Same stitches, very different pictures. Our guide to 14-count Aida goes into when each count makes sense.

What changes with evenweave and linen?

Evenweave and linen have no big, obvious holes like Aida does. The usual way to work them is "over two," which means each cross covers two threads in each direction. DMC says:

"If you prefer to stitch on linen or evenweave the stitches are commonly made "over 2" meaning each stitch is made across two intersections of thread as shown in the diagrams here."

DMC, What is cross stitch?

That halves the count. So 28-count evenweave over two stitches like 14-count Aida, and 32-count linen over two stitches like 16-count Aida. You can see this in the table. The rows match.

People often look for evenweave cross stitch and linen cross stitch fabric when they want a softer, finer look. The sums stay the same. Just divide the thread count by two before you start.

Common mistakes with fabric size

Three trip people up most.

Forgetting the over-two rule

Say you divide 120 by 28 on 28-count evenweave. You get 4.3 inches. But you are stitching over two threads, so the real width is 8.6 inches. Cut for 4.3 inches and your cloth is far too small.

Leaving no margin

A design cut to its exact size has nothing to hold. You need room to grip the cloth, and to mount it. If you plan to use a hoop or frame, check how much cloth it needs around the edge, and make the margin at least that. We use 3 inches in our tools.

Mixing up the fabric and the chart

The chart size in stitches never changes. Only the inches do. If you switch from 14-count to 18-count after you have cut your cloth, the design shrinks and the cloth you cut is now too large. Pick the fabric first, then cut.

How big a margin should I leave?

Our tools use 3 inches on every side. It is a good middle choice.

Use 2 inches if you are short on cloth and will frame the piece with a close mat. Use 4 inches if you want room to handle the work for months and trim at the end. Look at the table above and you can see what each choice costs. On 14-count, the step from 2 to 4 inches adds 4 inches to each dimension.

There is no magic number, but never go below 2 unless you know why.

Thread follows fabric

Fabric changes the thread bill too. Our wave chart has 25 threads and needs 26 skeins on 14-count Aida, because the busiest thread, Ecru, uses 2,356 stitches and needs 2 skeins. Check your own chart with the floss calculator before you shop.
