Cross Stitch Fabric Count Conversion: What the Numbers Actually Mean

The short answer: Fabric count tells you how many stitches fit in one inch. To convert between counts, divide the count number into the total stitch width or height of your design. A 100-stitch-wide pattern on 14-count aida covers about 7.1 inches. The same pattern on 28-count evenweave stitched over two threads also covers 7.1 inches. Count and thread-over determine everything.

What does "fabric count" actually mean?

Fabric count is the number of holes (or threads) per inch in your ground fabric. On 14-count aida, you get 14 stitches per inch. On 18-count, 18 stitches per inch. That single number controls how large or small your finished piece will be.

This is not a loose approximation. The Zweigart fabric specifications for their standard 14-count aida list exactly 14 holes per inch, and their 18-count lists 18. When manufacturers say "count," they mean a consistent, measurable thread density. Your job is to use that number as a conversion factor.

Think of count the way a knitter thinks about gauge: stitches per inch. If you know your stitch count and you know your fabric count, you can always find the finished size.

How do I calculate finished size from stitch count?

Divide your total stitch count by the fabric count to get finished inches. Do that separately for width and height. A 140 x 200 stitch design on 16-count aida works out to 8.75 x 12.5 inches of stitched area, before you add any framing or hoop margin.

Divide your stitch count by the fabric count. That gives you inches. Do it for width and height separately.

If your pattern is 140 stitches wide by 200 stitches tall, and you're working on 16-count aida:

• Width: 140 / 16 = 8.75 inches
• Height: 200 / 16 = 12.5 inches

Add at least 3 inches on each side for a hoop margin or framing allowance, so your fabric needs to be at least 14.75 x 18.5 inches. Most stitchers round up to the nearest inch and add a bit more. I personally add 4 inches per side on anything going to a framer.

How do I convert a pattern from one count to another?

Keep your stitch count exactly the same and just swap the fabric count number in the formula. The design does not change, only the finished size does. Moving that same 140 x 200 pattern from 14-count to 18-count shrinks the finished piece by roughly two inches in each direction.

Keep the stitch count the same and change the divisor. The math is the same formula, just with a different count number.

Same 140 x 200 stitch pattern from above:

Notice that 14-count aida and 28-count evenweave stitched over two threads produce identical finished sizes. That relationship holds across all evenweave counts: 28-count over 2 equals 14-count, 32-count over 2 equals 16-count, 36-count over 2 equals 18-count.

What is the difference between aida and evenweave counts?

Aida is woven in blocks, so each "count" unit is one block with one obvious hole. Evenweave is woven in individual threads, so you stitch over two threads to create a stitch the same visual size as one aida block.

This is why you will see patterns specify "28-count evenweave, stitched over two." If you stitch over one thread on 28-count, your stitches are tiny and your finished piece is half the size you expected. The Needlework Tips and Techniques guide from DMC covers this distinction and is worth bookmarking.

Linen behaves like evenweave in this way. 32-count linen stitched over two threads gives you a 16-count equivalent. The thread count on linen can vary slightly within a piece because linen is a natural fiber, so measure your actual fabric if precision matters for your project.

Can I use this conversion to resize a design?

Yes, with one caveat: you are resizing the physical dimensions, not the stitch count. The number of stitches in the design stays the same. Only the fabric you choose changes how large or small those stitches appear on the cloth.

If you want a portrait that currently works out to 10 x 14 inches on 14-count and you need it to fit in an 8 x 10 frame, you need a higher count fabric. Work backwards:

• Frame opening is roughly 7.5 x 9.5 inches (standard mat opening for 8x10)
• 140 / 7.5 = 18.7, so you need approximately 18-count fabric
• 200 / 9.5 = 21.1, so you actually need closer to 22-count

When the width and height don't land on the same count, you have to pick one count and accept that the design will be slightly taller or wider than the frame opening, then adjust your mat or crop your margin. This is a real trade-off, not a math error.

Are there tools that do this conversion automatically?

Yes. The fibertools.app fabric count calculator handles stitch count to finished size conversions and lets you compare multiple counts side by side without doing the arithmetic by hand. Useful when you are shopping for fabric and need to quickly check whether a piece you already own is large enough.

Beyond that, most major pattern software like PC Stitch and StitchCraft Creator will display finished dimensions as you adjust count in the project settings.

Quick reference: common count conversions

Every aida count has a direct evenweave equivalent stitched over two threads. Fourteen-count aida matches 28-count evenweave, 16-count matches 32-count, and so on. The stitch density stays identical, so your finished size calculation works the same way regardless of which fabric type you choose.

The formula never changes: finished inches = stitch count / fabric count. Everything else in cross stitch sizing is just this equation applied in different directions.

Frequently asked questions

What is fabric count in cross stitch?

Fabric count refers to the number of threads or holes per inch in cross stitch fabric. A higher count means more threads packed into each inch, resulting in smaller, finer stitches. Common counts include 14-count Aida, 18-count Aida, and 28-count evenweave. Choosing the right count affects the finished size of your project and the level of detail achievable in your design.

How do I convert a cross stitch pattern from 14-count to 18-count fabric?

To convert between fabric counts, divide the original count by the new count and multiply your pattern dimensions by that ratio. For example, a design that measures 5 inches on 14-count Aida will measure approximately 3.9 inches on 18-count fabric. The stitch count of the pattern itself stays the same — only the physical finished size changes based on the fabric you choose.

What is the difference between Aida and evenweave fabric counts?

Aida fabric is woven in blocks, making each stitch cross one block, while evenweave fabric has individual threads you typically stitch over two. A 28-count evenweave produces the same stitch size as 14-count Aida because you cross two threads per stitch. When converting patterns between these fabric types, always account for whether you're stitching over one or two threads on the evenweave.

How does fabric count affect the finished size of a cross stitch project?

Fabric count directly determines how large or small your finished embroidery will be. Dividing the total stitch count of a design by the fabric count gives you the finished size in inches. A 140-stitch-wide design on 14-count fabric produces a 10-inch width, while the same design on 28-count fabric produces only 5 inches. Always calculate finished dimensions before purchasing fabric to ensure you have enough material.

Can I use a cross stitch fabric count conversion calculator for any fabric type?

Yes, a fabric count conversion calculator works for Aida, evenweave, linen, and other counted fabric types. Simply input your current fabric count, desired new count, and original design dimensions to get accurate results. Tools like the converter on fibertools.app make it easy to plan projects across different fabric types, helping you visualize finished sizes before you buy materials or begin stitching.
