Two fundamental numbers determine the physical size of your finished cross stitch embroidery:
- Stitch Count: A property of the pattern design (e.g., 200 stitches wide by 150 stitches high).
- Fabric Count (Aida Count): A property of the fabric weave, indicating how many squares (or stitches) fit into one linear inch.
Neither number alone tells you how large the finished piece will be.
The core sizing formula is straightforward:
Finished Width (inches) = Total Horizontal Stitches ÷ Aida Fabric Count
Finished Height (inches) = Total Vertical Stitches ÷ Aida Fabric Count
For example, a 200-stitch wide pattern stitched on 14-count Aida measures 200 ÷ 14 ≈ 14.3 inches (36.3 cm).
Stitched on 18-count Aida, that exact same pattern measures 200 ÷ 18 ≈ 11.1 inches (28.2 cm).
Same chart, same DMC colors, same number of stitches—over three inches smaller simply by switching the fabric weave!
Finished Size Reference Table
Here are finished design dimensions (width in inches and centimeters) across common stitch counts:
| Stitch Width | 11 ct Aida | 14 ct Aida | 16 ct Aida | 18 ct Aida |
|---|---|---|---|---|
| 100 stitches | 9.1" (23.1 cm) | 7.1" (18.1 cm) | 6.3" (15.9 cm) | 5.6" (14.1 cm) |
| 150 stitches | 13.6" (34.6 cm) | 10.7" (27.2 cm) | 9.4" (23.8 cm) | 8.3" (21.2 cm) |
| 200 stitches | 18.2" (46.2 cm) | 14.3" (36.3 cm) | 12.5" (31.8 cm) | 11.1" (28.2 cm) |
| 250 stitches | 22.7" (57.7 cm) | 17.9" (45.4 cm) | 15.6" (39.7 cm) | 13.9" (35.3 cm) |
| 300 stitches | 27.3" (69.3 cm) | 21.4" (54.4 cm) | 18.8" (47.6 cm) | 16.7" (42.3 cm) |
| 400 stitches | 36.4" (92.5 cm) | 28.6" (72.6 cm) | 25.0" (63.5 cm) | 22.2" (56.4 cm) |
Always calculate from the frame inward
Most experienced stitchers plan from their target frame size backward rather than sizing the chart first.
Ready-made picture frames and embroidery hoops come in fixed standard dimensions (such as 8×10", 11×14", or 16×20"). If you generate a chart without planning for a frame, you risk completing 40 hours of needlework only to discover the piece is half an inch too wide for a standard frame, requiring custom framing.
The recommended planning workflow:
- Pick your desired frame size or hoop diameter.
- Deduct framing margins (see below) to determine your maximum stitched area.
- Multiply that stitched width by your chosen Aida count to establish your maximum stitch count.
- Set your chart width in StitchCraft to match.
Don't forget fabric cutting margins!
The dimensions in the table above represent the stitched area only.
When cutting raw fabric, you must include generous margins on all four sides:
- Add at least 3 inches of blank fabric on every side (which adds 6 inches total to both fabric width and height).
- For example, a 14×10" stitched design requires a fabric cut of at least 20×16 inches.
- These margins are essential for hoop clamping, tension scroll bars, edge fraying protection, and final framing wrap-around.
Choosing the right Aida count for your project
- 11-count Aida: Large, visible holes that are easy on the eyes. Ideal for beginners, children, or rustic folk-art designs. Typically stitched with 3 strands of DMC floss.
- 14-count Aida: The gold standard in cross stitch. Readily available in hundreds of colors, comfortable to sew, and provides great detail. Stitched with 2 strands of floss.
- 16-count Aida: Noticeably crisper and more compact. Perfect for fitting detailed portraits into standard-sized frames without eye fatigue. Stitched with 2 strands.
- 18-count Aida: Fine, dense weave that yields near-photographic detail in compact finished dimensions. Requires good lighting and a sharp needle. Stitched with 1–2 strands.
Linen and Evenweave conversion
When working on linen or evenweave fabric, counts are typically quoted in threads per inch, and cross stitch is usually worked over two threads (e.g., 28-count linen stitched over two behaves identically to 14-count Aida).
Divide the fabric's quoted thread count by 2 to find its equivalent Aida count when using sizing calculators.
