Aida Count Explained: Cross Stitch Fabric Sizes and How to Choose
What aida count means, a sizes chart for every common count, and how to choose the right fabric — with the finished-size math worked out.
Before you stitch a single X, one number decides how big your finished piece will be, how much detail it can hold, and how hard your eyes will work: the count of your fabric. Get it wrong and your “small” ornament turns into a placemat, or your detailed portrait shrinks to something you need a magnifier to finish. This guide explains what count actually is, the simple math that turns a stitch count into inches and centimeters, and how to pick the right fabric for the project in front of you.
What “count” actually means
The aida count is the number of squares — and therefore the number of stitches — per linear inch of fabric. Aida cloth is woven so the threads bunch into a regular grid of little blocks with a clear hole at each corner. You work one cross stitch per block, bringing the needle up and down through those corner holes. So on aida, count is the same thing as stitches per inch: 14-count aida gives you 14 blocks, 14 stitches, across one inch.
That one-block-one-stitch relationship is what makes aida the standard beginner fabric. You don’t have to count fabric threads or judge where a stitch goes — the weave hands you a printed-graph-paper grid in cloth form, and you just fill in the squares.
Higher count means more, smaller squares packed into the same inch. The thread itself is finer and the holes sit closer together, so each stitch is physically smaller. Two consequences follow, and they’re the whole reason count matters:
- Higher count = smaller stitches = more detail in less space. A face, lettering, or a gradient sky needs many stitches to read clearly. On a higher count you can fit those stitches into a frame that still fits on a wall.
- Higher count = harder on the eyes and hands. Smaller holes are harder to see and to hit with the needle, and you’re making more stitches per square inch to cover the same area.
So count is a trade between detail and finished size on one hand, and comfort and speed on the other. Everything else in this guide is about navigating that trade deliberately instead of by accident.
A quick note on what count is not: it has nothing to do with how good the fabric is or how many strands of floss you use. A cheap and an expensive 14-count aida have the same grid. The number of strands you stitch with (usually two on 14-count) is a separate decision driven by coverage, which we touch on later.
The count → finished-size formula
Here’s the only equation you truly need:
Finished size (inches) = stitch count ÷ fabric count
Your design has a width and a height measured in stitches — that’s fixed by the chart, not the fabric. Divide each by the count of the cloth you’ll stitch it on, and you get the finished dimensions of the stitched area.
Work an example. Say your chart is 140 stitches wide by 196 stitches tall, and you’re stitching on 14-count aida:
- Width: 140 ÷ 14 = 10 inches
- Height: 196 ÷ 14 = 14 inches
Move the same chart to 18-count aida and nothing about the design changes — you still make 140 × 196 stitches — but each stitch is smaller:
- Width: 140 ÷ 18 = 7.78 inches
- Height: 196 ÷ 18 = 10.89 inches
Same number of stitches, same picture, noticeably smaller piece. That’s the lever count gives you.
To get centimeters, multiply inches by 2.54. The 14-count version above is 10 × 14 inches, which is 25.4 × 35.6 cm. (If you prefer to skip the conversion, you can divide stitch count by stitches per cm: 14-count aida is 14 ÷ 2.54 ≈ 5.5 stitches per cm.)
One more worked case, going the other direction — sizing a small motif. A little 45 × 45 stitch heart on 16-count aida:
- 45 ÷ 16 = 2.81 inches square (about 7.1 cm) — a true ornament size.
The formula scales to anything. The rest is knowing which count to put in the denominator, which is what the next sections are for.
Aida count sizes: the full reference table
These are the aida count sizes you’ll actually meet, from chunky kids’ cloth up to the fine counts that blur into evenweave territory. “Relative stitch size” is eyeballed against 14-count as the familiar middle.
| Count | Stitches per inch | Relative stitch size | Best for | Notes |
|---|---|---|---|---|
| 8 | 8 | Very large | Young children, classroom kits, quick wall hangings | Big holes, thick yarn or 6 strands of floss; almost impossible to misplace a stitch |
| 11 | 11 | Large | Beginners who want fast progress, kids, bold samplers | Stitches show clearly from across a room; uses ~3 strands; pieces get big fast |
| 14 | 14 | Standard | The default for most stitchers and most kits | The reference count; 2 strands; best balance of detail, size and comfort |
| 16 | 16 | Slightly small | Stitchers wanting more detail without a big jump | A modest step finer than 14; 2 strands; portraits and busier charts read better |
| 18 | 18 | Small | Detailed designs, smaller framed pieces | 2 strands (some use 1); noticeably finer — good light helps |
| 20 | 20 | Small | Detail work, compact finished sizes | Less common on the shelf than 14/16/18; 1–2 strands |
| 22 | 22 | Very small | Fine detail, miniatures, tiny ornaments | Often called hardanger when used as evenweave; 1 strand typical; magnification recommended |
| 25 | 25 | Very small | Usually stitched as evenweave | Sold as an evenweave; commonly worked over 2 threads → effectively ~12.5 stitches/inch |
| 28 | 28 | Extra small (as aida) | Almost always evenweave, stitched over 2 | Over 2 threads it behaves like 14 stitches/inch — see below |
A few of these need unpacking, because the raw count number can mislead you.
Why 28-count often behaves like 14-count
28-count aida (and 28-count evenweave, which is far more common at that fineness) is the classic trap. If you read “28” as “28 stitches per inch,” you’ll size your project at half its true dimensions.
In practice almost nobody works 28-count one-stitch-per-hole — the blocks are tiny. Instead you stitch over 2 threads (or over 2 blocks): each cross spans a 2×2 area rather than a single one. That halves the effective resolution. So 28-count worked over 2 = 14 stitches per inch, and your finished size matches 14-count aida exactly.
The same logic applies up and down the fine counts:
- 25-count over 2 → 12.5 stitches per inch (close to 11-count in size)
- 28-count over 2 → 14 stitches per inch (identical to 14-count aida)
- 32-count over 2 → 16 stitches per inch (identical to 16-count aida)
This is why experienced stitchers pair counts in their head: 28-over-2 and 14-count give the same scale, just a different look and feel. The rule to remember: on evenweave and linen, divide the count by 2 to get your real stitches per inch, because “over 2” is the norm there. We’ll come back to this when we compare fabrics.
Finished-size table: one chart, every count
Formulas are easier to trust when you can see them laid out. Below are two real designs sized across the five counts you’re most likely to choose.
Design A — a small-to-medium motif, 90 × 90 stitches (think a tidy square sampler block or a medium ornament):
| Aida count | Effective stitches/inch | Finished width | Finished height | In centimeters |
|---|---|---|---|---|
| 11 | 11 | 8.18 in | 8.18 in | 20.8 × 20.8 cm |
| 14 | 14 | 6.43 in | 6.43 in | 16.3 × 16.3 cm |
| 16 | 16 | 5.63 in | 5.63 in | 14.3 × 14.3 cm |
| 18 | 18 | 5.00 in | 5.00 in | 12.7 × 12.7 cm |
| 22 | 22 | 4.09 in | 4.09 in | 10.4 × 10.4 cm |
The same 90 stitches range from a generous 8-inch piece on 11-count down to a palm-sized 4-inch piece on 22-count. If you wanted that motif to fit a 5-inch hoop, 18-count is your answer — and the table tells you so without guessing.
Design B — a larger, detailed piece, 140 wide × 180 tall (a portrait, a landscape, a full sampler):
| Aida count | Effective stitches/inch | Finished width | Finished height | In centimeters |
|---|---|---|---|---|
| 11 | 11 | 12.73 in | 16.36 in | 32.3 × 41.6 cm |
| 14 | 14 | 10.00 in | 12.86 in | 25.4 × 32.7 cm |
| 16 | 16 | 8.75 in | 11.25 in | 22.2 × 28.6 cm |
| 18 | 18 | 7.78 in | 10.00 in | 19.8 × 25.4 cm |
| 22 | 22 | 6.36 in | 8.18 in | 16.2 × 20.8 cm |
Now the stakes of count are obvious. The very same chart is a 12.7 × 16.4 inch wall piece on 11-count — too big for most standard frames — and a neat 7.8 × 10 inch piece on 18-count that drops straight into an off-the-shelf 8×10 frame. The detail is identical in stitch terms; only the scale and the difficulty change. This is the single most common reason a finished piece doesn’t fit its intended frame: the count was chosen by habit, not by the math.
How to choose a count
Count is a personal fit, not a rule. Run through these five questions and the answer usually falls out on its own.
1. Your eyesight and your light. This dominates everything. If you wear reading glasses or stitch in the evening under a lamp, every count finer than 14 fights you — the holes get hard to see and you start splitting threads instead of going through holes. Honest self-assessment here saves more abandoned projects than any other factor.
2. Magnification. A clip-on magnifier or a magnifying floor lamp effectively buys you two counts of headroom. With good magnification, 18- and 22-count become comfortable; without it, they’re a slog. If you own one, factor it in; if you don’t, choose as though the finest comfortable count is 16.
3. Project type and target size. Work backward from where the piece will live. A greeting card insert wants a small finished size, so a higher count. A wall hanging meant to read from across a room wants bold stitches, so 11 or 14. A piece destined for a specific frame should be sized by the formula above to land on that frame’s opening.
4. How much detail the design needs. Photo conversions, faces, smooth gradients, and small lettering all need a lot of stitches to look right. If you force a detailed chart onto a low count, the finished piece balloons in size; if you want detail and a reasonable size, you need a higher count to fit those stitches in. Flat, graphic, few-color designs are happy on any count.
5. How fast you want to finish. Lower count, fewer total stitches per square inch, faster finish — and faster is what keeps a project moving instead of into the drawer. Higher count means more stitches for the same picture and a longer haul. There’s no virtue in choosing a count that bores you before you’re done.
The beginner recommendation
If you’re starting out, stitch your first few projects on 14-count white aida, two strands of floss. Here’s the reasoning, not just the rule:
- The holes are easy to see and hit in ordinary room light, so you spend your attention on the pattern, not on finding the next hole.
- Two strands give full, even coverage with no fiddling — the most forgiving setup there is.
- Finished sizes are sensible. Most small-to-medium charts land between a hoop and a small frame, so you see a finished object soon, which is what builds the habit.
- White shows your stitches and your symbols clearly, and white aida is the cheapest, most available cloth, so a mistake costs nothing to redo.
- It’s the default the whole craft is built around. Most kits, charts, and tutorials assume 14-count, so your stitch counts, floss estimates, and finished sizes all match what you read everywhere else.
Once 14-count feels easy and you want more detail in less space, step to 16, then 18. That’s the natural progression, and there’s no prize for skipping it.
If you’re turning a photo into a chart, the same logic holds — a portrait wants more stitches than a logo. Our guide to convert a photo into a cross stitch pattern walks through choosing stitch width and color count, which interact directly with the fabric count you land on.
Fabric margin: how much to cut
The finished-size formula gives you the stitched area only. You can’t stitch a piece edge to edge — you need bare fabric around it to mount it in a hoop while you work and to frame, mat, or hem it when you’re done. Cut too tight and the piece is unframeable; this is a genuinely common and painful mistake.
The working rule: add about 3 inches of margin on every side — so add roughly 6 inches to both the width and the height of the stitched area. Three inches is enough to seat the work in a hoop, leave room for a frame’s rebate, and give you something to hold and to finish.
Worked example. Take Design B on 14-count aida, which we sized at 10 × 12.86 inches of stitching:
- Cut width: 10 + 3 + 3 = 16 inches
- Cut height: 12.86 + 3 + 3 ≈ 18.86 inches, round up to 19 inches
So buy or cut a piece at least 16 × 19 inches for that project. Round generously — extra fabric trims off, but you can’t add it back. For a very small motif, 3 inches a side can feel like a lot relative to the design, but 2 inches is the bare minimum even then, mostly so the hoop has something to grip beyond the stitching.
If you’ll mount the piece in a hoop as the finished frame (a popular modern finish), the same 3-inch margin works — it gives you fabric to gather and glue behind the inner ring.
Aida vs. evenweave vs. linen
Aida is one of three families of counted cross stitch fabric, and the difference is mostly about the weave and how “over how many threads” you stitch.
- Aida is woven into distinct blocks with obvious holes. One stitch per block. Count = stitches per inch. It’s structured, beginner-friendly, and the most common kit fabric.
- Evenweave (Lugana, Brittney, Jobelan and the like) is a smoother, more uniform single-thread weave with the same number of threads vertically and horizontally. There are no pre-formed blocks, so you stitch over 2 threads to make each cross sit square.
- Linen is a natural single-thread weave with deliberate slubs and irregularities that give it a soft, organic look. Like evenweave, you stitch over 2 threads.
The practical takeaway is the one from the 28-count discussion: on evenweave and linen, divide the count by 2 to get your effective stitches per inch, because over-2 is the standard. So:
| Fabric | Count | How it’s stitched | Effective stitches/inch | Equivalent aida |
|---|---|---|---|---|
| Aida | 14 | Over 1 block | 14 | 14-count |
| Evenweave | 28 | Over 2 threads | 14 | matches 14-count aida |
| Linen | 32 | Over 2 threads | 16 | matches 16-count aida |
| Linen | 36 | Over 2 threads | 18 | matches 18-count aida |
This is why a pattern can be sold “for 28-count evenweave or 14-count aida” — same finished size, different fabric feel. Linen and evenweave give a finer, more heirloom look and let you do over-1 detail in small areas, but they ask you to count threads, which is why most people meet them after aida. For the mechanics of working over 2 and reading the chart against the weave, see how to read a cross stitch pattern — it’s the natural next step once your fabric is sorted.
Aida colors and how they change the look
Aida comes in a wide range of colors, and the background is part of the design — it shows everywhere you don’t stitch and tints how the floss reads.
- White is the default: maximum contrast, your colors stay true, and printed symbol charts are easiest to follow against it. It’s the right call for bright, multicolor, and beginner pieces.
- Ecru / antique white / cream softens everything a half-step. It flatters skin tones, vintage samplers, and anything you want to look warm rather than crisp. A common, low-risk alternative to white.
- Black (and other darks) makes bright and neon colors pop and gives a dramatic, modern look — but it’s genuinely harder to stitch on, because the holes vanish into the dark cloth. Save it for when the effect is worth the eye strain, and stitch it under strong light. Light floss colors will also need full coverage so the dark fabric doesn’t shadow through.
- Hand-dyed and variegated aida carries mottled tones across the cloth, so the background does design work for you — beautiful under sparse, monochrome, or sampler-style charts where the fabric shows a lot. It tends to fight busy, full-coverage designs, where you’d never see it.
A rule of thumb: choose the fabric color to complement the unstitched space, and remember that pale floss shows poorly on pale fabric and dark floss disappears on dark fabric. If a design leaves a lot of background bare, the fabric color matters enormously; if it’s stitched corner to corner, almost any color works because you’ll barely see it.
Converting a design to a different count
Because finished size is just stitch count ÷ fabric count, you can resize a design without changing the design at all — same chart, same stitches, new dimensions. You’re only swapping the fabric.
Suppose you have a chart finished at 8 × 10 inches on 14-count aida and you want it smaller to fit a card. First recover the stitch count (it’s fixed):
- Width: 8 × 14 = 112 stitches
- Height: 10 × 14 = 140 stitches
Now drop those same stitch counts onto a finer fabric — say 18-count:
- Width: 112 ÷ 18 = 6.22 inches
- Height: 140 ÷ 18 = 7.78 inches
A 25% reduction, with not one stitch added or removed. Go finer still, to 22-count (or 28-count evenweave worked over 2, which is ~14 — that would keep it the same, so for smaller you want a higher effective count):
- Width: 112 ÷ 22 = 5.09 inches
- Height: 140 ÷ 22 = 6.36 inches
The reverse works too: to make a piece bigger — for a child to stitch, say — move it to a lower count. The same 112 × 140 chart on 11-count aida becomes 112 ÷ 11 = 10.18 by 140 ÷ 11 = 12.73 inches.
Two cautions when you change count this way. First, your floss requirement changes: finer counts use fewer strands and a bit less floss per area, coarser counts use more — so re-estimate skeins rather than trusting the old count. Second, fine counts demand the eyesight and light from the choosing section; resizing down is easy on paper and harder at the needle, so be honest about whether you’ll enjoy 22-count before you commit the fabric.
Planning your project
Fabric planning comes down to three numbers and one formula. Your chart’s stitch count is fixed by the design. Your fabric count is the lever you choose for size, detail, and comfort. Divide the first by the second and you have your finished size; add ~3 inches a side and you have your cut size. Everything else here is variations on that.
If you’d rather not run the arithmetic by hand, that’s exactly what the tool does. When you make a chart in Samplerly’s cross stitch pattern maker, it shows the finished size for your chosen aida count live as you set the stitch width and pick the cloth — so you can dial in a count that lands on the frame you have, before you ever thread a needle. Pair that readout with the cut-size rule above and the cloth you buy will fit the piece you’re about to stitch.
