A Free Calculator · Any Stitch Count · Any Aida Count
How much Aida fabric do you need for your cross-stitch?
The fabric size for a cross-stitch project is not a guess — it is arithmetic. Your pattern gives
you a stitch count; the fabric label gives you a count (stitches per inch); you choose your border
margin. Divide and add. This calculator does that for any combination and shows every step.
Finished design size·Fabric to cut·Any Aida count
Read this first
This calculator is built for Aida cloth, where the count equals stitches per inch and
one stitch occupies one square. Evenweave (linen, Jobelan, etc.) is stitched over 2
threads, which halves the effective count — 28-count evenweave stitched over 2 behaves like 14-count
Aida. If you are working on evenweave, enter half the thread count in the Aida count field, or read
the evenweave note in the FAQ below.
Enter your design's stitch dimensions, your Aida count, and the border margin you want on each side. Results update as you type.

The formulas, in full
Nothing here is a black box. These are the exact calculations the tool runs — the same
arithmetic you could do on a scrap of paper. Count determines physical scale; margin
determines how much unstitched fabric surrounds the design.
How each number is derived
1 — Finished design width (what your stitching will measure)
design_width_in = stitches_wide ÷ aida_count
2 — Finished design height
design_height_in = stitches_high ÷ aida_count
3 — Fabric width to cut (design plus border on both sides)
Evenweave note (labeled — not used in the Aida calculation)
evenweave_effective_count = thread_count ÷ 2
(e.g., 28-count linen over 2 threads → effective count of 14)
Common Aida counts — what a 140-stitch design produces
The same 140-stitch pattern produces very different physical sizes depending on the count you choose.
Higher count means smaller stitches and a smaller finished design; lower count means bigger stitches
and a more visible result from across a room. The table below shows finished design size and a
minimum fabric cut (at 3″ margin per side) for each common count.

Best for
11-count
Large squares — ~1/11″ each
12.7″ × 12.7″
18.7″ × 18.7″
Beginners, quick gifts, chunky wall art, projects where thread coverage needs to be fast.
14-count
Standard squares — ~1/14″ each
10.0″ × 10.0″
16.0″ × 16.0″
The most widely sold count. Suits most commercial patterns; good balance of speed and detail.
16-count
Medium-fine — ~1/16″ each
8.75″ × 8.75″
14.75″ × 14.75″
More detail than 14-count, still manageable without magnification for most stitchers.
18-count
Fine — ~1/18″ each
7.8″ × 7.8″
13.8″ × 13.8″
Miniature work, ornaments, highly detailed portraits. Often benefits from magnification.
Design sizes are exact (140 ÷ count). Fabric cut sizes assume 3″ margin per side and are
rounded to one decimal place. Actual thread count on Aida can vary slightly between manufacturers
and dye lots — treat these as planning figures.
Why the margin matters — and how to choose it
The margin is not decorative padding — it is working material. It must be large enough to hold in
a hoop without the hoop touching the stitched area, and deep enough to fold or mount the finished
piece cleanly. Getting it wrong means either hoop-damaged stitching or a design that cannot be
framed without cropping.
The hoop sets your minimum margin
An embroidery hoop clamps the fabric a ring-width away from your needle. The inner ring of a standard 6″ hoop has a lip roughly 1″ deep, which means at least 1″ of fabric is held outside the stitching area. If your design fills the hoop, you have no working margin — the hoop will crush your completed stitches when you move it. The safest rule: your margin should be at least as wide as the widest hoop you plan to use on the piece, with a 2″–3″ target covering nearly all standard home hoops.
Framing and mounting consume margin
A framed piece needs fabric to fold behind the mat or mount board. A standard lacing or stretcher-bar mount consumes roughly 1.5″–2″ of fabric on each side. A professional framer may want even more. If you cut fabric to the minimum and then frame, you may find that pulling the fabric taut removes any slack — the design can shift, or stitches at the edge can pull tight. A 3″ margin gives the framer material to work with and still leaves room for any slight misalignment during mounting.
Fraying eats into your margin during stitching
Aida frays visibly with handling. Every time you pull the fabric through the hoop or rest it on a table, threads along the cut edge loosen. Over a long project, a 1″ margin can fray down to nearly nothing. Most experienced stitchers finish the cut edges with masking tape, a zigzag machine stitch, or fray-check liquid before the first stitch goes in. Even with edge finishing, plan for some loss — which is another reason a 3″ margin is safer than 2″ on any project you expect to handle for more than a few sessions.
How to read the stitch count from your pattern
Every cross-stitch chart encodes its dimensions in stitches, not inches. Finding the numbers
usually takes less than a minute; the field to check depends on where the pattern came from.
Check the pattern's header or cover sheet
Commercial patterns (DMC, Dimensions, Anchor) print stitch count on the front of the package or in the first paragraph of the instructions — typically as "Stitch count: 140W × 140H" or "Design area: 140 × 140 stitches." If it says "finished size on 14-count," that's the result of dividing already; multiply back by 14 to recover the stitch count if you want to use a different count.
Count the chart squares directly
If the documentation is missing or unclear, open the chart and count the colored squares from edge to edge — that is your stitch count. Most charting software (PC Stitch, Pattern Maker, cross-stitch apps) displays a running stitch count as you scroll, so you may not need to count manually.
Use the chart's grid lines as shortcuts
Cross-stitch charts are printed with bold grid lines every 10 squares. Count the 10-square blocks, multiply by 10, and add any partial blocks at the edges. For a 140-stitch design you would see exactly 14 complete blocks in each direction — a quick visual check that confirms your count before you cut anything.
Verify with the expected finished size
If your pattern states a finished size (e.g., "10″ × 10″ on 14-count"), cross-check by dividing your stitch count by the count: 140 ÷ 14 = 10″. A mismatch means either the stated size is wrong, you misread the count, or the pattern uses a non-standard count. Resolve it before cutting fabric — a 10% error in count translates to a 10% error in finished size.
Where to buy
Got your numbers? Here's where to pick up what you need:
The vocabulary on a pattern envelope, fabric bolt, or stitching forum — in plain English.
Aida count
The number of fabric squares (and therefore stitches) per inch, printed on the bolt or package label. A higher count means smaller squares and a finer, more detailed finished piece from the same pattern. The most widely sold count is 14.
Stitch count
The dimensions of a cross-stitch design measured in stitches — typically written as "W × H" (e.g., 140 × 140). The stitch count is fixed by the pattern; the physical size it produces depends on the Aida count you use.
Aida cloth
A woven fabric with a regular grid of evenly spaced squares. Each square holds exactly one cross stitch. The squares are created by groups of threads woven together, leaving visible holes at each corner — the needle passes through the holes, not through the threads. The defining characteristic is that count (squares per inch) equals stitches per inch with no conversion needed.
Evenweave
A category of fabric (linen, Jobelan, Monaco) woven with individual threads rather than grouped squares. Cross-stitchers work over 2 threads of evenweave fabric, which halves the effective stitch density: 28-count evenweave stitched over 2 behaves like 14-count Aida and produces the same finished size from the same pattern. The calculator above uses Aida; for evenweave, enter half the thread count.
Margin (border allowance)
The unstitched fabric surrounding the design on all four sides. It must be large enough to fit in a hoop without the hoop touching the stitching, and wide enough to fold behind a mount or frame. The standard recommendation is 3 inches (about 7.5 cm) per side for framed or mounted work.
Embroidery hoop
Two concentric rings — inner and outer — that grip the fabric under tension. The hoop is placed over the fabric and tightened, stretching the Aida flat so each square hole is clearly visible and needle entry is consistent. Because the hoop holds the fabric at the edge of the stitching area, the margin must be at least as wide as the hoop's ring depth.
Finished design size
The physical measurement (in inches or centimeters) of the stitched area on the fabric — that is, the stitch count divided by the Aida count. A 140 × 140 design on 14-count Aida produces a 10″ × 10″ finished design, not counting any border or margin. This is the size that appears on pattern packaging as "design area" or "stitch area."
Fabric to cut
The total piece of Aida you purchase and cut before stitching — the finished design size plus twice the margin in each dimension (once for each side). This is the number the calculator outputs and the size you look for on the fabric bolt.
Frequently asked
You need enough fabric so that your finished design fits with border (margin) on all four sides. The formula: divide the design's stitch width by the Aida count to get the finished design width in inches, then add twice your desired margin (once for each side). For example, a 140-stitch-wide design on 14-count Aida is 10 inches across; with a 3-inch border on each side, you cut a 16-inch-wide piece. Repeat for height. The calculator above does this automatically for any combination.
Aida count — often called "count" or "ct" — is the number of squares (and therefore stitches) per inch of fabric. 14-count Aida has 14 squares per inch, so 14 stitches cover 1 inch of width. A higher count means smaller, finer stitches and a smaller finished design from the same stitch pattern. Common counts are 11 (large, good for beginners), 14 (the most popular all-purpose count), 16, and 18 (fine detail, often used for miniature work). The count is printed on the fabric bolt or package label.
Most stitchers allow 2–3 inches (5–8 cm) of unstitched fabric on each side. The reason is practical, not aesthetic: you need enough fabric to hold in an embroidery hoop without the hoop touching your stitching, and enough to fold and mount or frame the piece later without cutting into the design. A 3-inch margin is the common recommendation for projects that will be framed or mounted; 2 inches works for small ornaments or pieces where framing is not planned. If your hoop is unusually large or you plan to stretch the piece on a frame, increase the margin accordingly.
Aida is woven in a grid of distinct squares — each square is one stitch, and the count tells you directly how many stitches per inch. Evenweave (such as 28-count linen or Jobelan) has individual threads with no distinct squares. Cross-stitchers work over two threads of evenweave, which halves the effective count: 28-count evenweave stitched over 2 gives the same stitch density as 14-count Aida, and a 140-stitch design on it will produce the same 10-inch design width. The calculator above is built for Aida. For evenweave, halve the count before entering it (e.g., enter 14 for 28-count evenweave), or use the "28-count evenweave over 2" option in the dropdown, which does this automatically.
The calculated fabric size is the minimum you should cut — it includes your stated border but no additional allowance for fraying or handling. Aida frays noticeably when handled repeatedly during stitching. Many stitchers add an extra 1–2 inches beyond the calculator's output and either zigzag-stitch the edges, apply masking tape, or use fray-check liquid before they start. The extra fabric can be trimmed away before framing. Think of the calculator's result as your target cut size, not a final trimmed dimension.
Cross-stitch charts list dimensions in stitch counts — the number of squares across and down the chart grid — not in physical length. That physical length only emerges when you divide by the Aida count. If a pattern says "14 cm × 14 cm on 14-count," that's already done the conversion for you; to work backward to stitch count, multiply the centimeter dimension by the stitches per centimeter for your count (14-count Aida has about 5.5 stitches per centimeter). For this calculator, you always enter stitch count, not physical size.
Yes, with a caveat. Plastic canvas comes in mesh counts just like Aida (7-count, 10-count, 14-count). If you know the stitch count of your pattern and the mesh count of your canvas, the formula is identical: divide stitches by count to get the physical size. The margin calculation differs — plastic canvas is often cut without any margin because it has rigid edges that do not fray. Enter 0 for the margin per side if you want the calculator to output just the stitched area size.
Because Aida count controls the physical size of each stitch. A 140×140 stitch design on 11-count Aida produces stitches about 1/11″ wide, so the design spans 140 ÷ 11 ≈ 12.7 inches. The same 140×140 design on 18-count Aida produces stitches 1/18″ wide, so it spans only 140 ÷ 18 ≈ 7.8 inches. The pattern — the arrangement and color of stitches — is unchanged; only the physical scale varies. This is why experienced stitchers choose their count deliberately: a higher count gives finer, smaller work; a lower count gives bolder, larger stitching.
Common mistakes with this calculator
Cross-stitch fabric sizing is straightforward when the inputs are right. These are the
errors that most often produce a piece of Aida that is too small to finish or frame.
Entering finished size in inches instead of stitch count
A pattern that says "10 × 10 inches on 14-count" has already done the division for you. Entering 10 in the stitch-count field — instead of 140 — tells the calculator you have a 10-stitch design, which produces a fabric cut of less than 1 inch. Always enter the stitch count (squares on the chart grid), not the physical finished size in inches or centimeters.
Treating 28-count evenweave as 28-count Aida
Evenweave fabric (linen, Jobelan, Monaco) is stitched over 2 threads, so 28-count evenweave produces the same stitch density as 14-count Aida. Entering 28 in the count field when you are working on 28-count evenweave will make the calculator think each stitch is half the size it actually is, producing a fabric cut that is far too small. Use the effective count — for evenweave over 2 threads, that is half the thread count.
Setting the margin too small for the planned finishing method
A 1-inch margin is enough to see the fabric — it is not enough to mount in a hoop, stretch over a frame, or fold behind a mat board for framing. A standard embroidery hoop requires margin at least as deep as the hoop's ring. For framed or mounted work, a 3-inch margin per side is the practical standard because the framer needs material to pull and lace behind the mount board. Cut too small, and the design cannot be finished without cropping stitches.
Not finishing cut edges before stitching
The calculator gives you the minimum fabric size to cut. Aida frays with every handling, and a long project worked over many sessions can lose a significant amount of margin to fraying before the last stitch goes in. Zigzag the edges, apply masking tape, or use fray-check liquid immediately after cutting — before the first stitch. The fabric you lose to fraying is fabric the calculator cannot recover.
