Cross Stitch Size Calculator: Fabric Dimensions, Aida Count & Margins

A cross stitch chart usually gives its dimensions in stitches, but fabric is sold in inches or centimetres. Before you cut your Aida, work out the actual stitched size, then add enough border for your preferred finish. This guide includes the formulas, worked examples and a practical cutting worksheet you can use without installing an app.

The basic cross stitch size formula

On Aida fabric, the count is the number of full cross stitches per inch when one stitch occupies one fabric square. A 14-count Aida supports approximately 14 full cross stitches across one inch; 18-count Aida supports 18. To find the finished stitched area:

Stitched width in inches = design width in stitches ÷ fabric count.

Stitched height in inches = design height in stitches ÷ fabric count.

To convert inches to centimetres, multiply the result by 2.54. Do not round until the end; rounding too early can make a borderline piece too small for your planned frame.

Example: a chart that is 112 stitches wide and 84 stitches high, stitched on 14-count Aida, produces an 8 × 6 inch stitched area: 112 ÷ 14 = 8 and 84 ÷ 14 = 6. In centimetres, that is approximately 20.32 × 15.24 cm. These are the design dimensions, not the size of the fabric you should cut.

Worked examples: identical charts on 14, 16 and 18 count Aida

Changing fabric count changes the physical size but does not change the chart’s total number of stitches. Use this comparison for a 100 × 80-stitch rectangular design.

Notice that higher count fabric produces a smaller finished picture and smaller individual X stitches. It does not automatically make the project faster: you still complete approximately the same number of charted stitches, and some people find smaller holes slower to work.

How much fabric margin should you add?

A piece cut exactly to the size of the stitched design is difficult to mount or finish. Many stitchers plan around 2–3 inches of extra fabric on each side for framing; the exact amount depends on the frame, backing and finish. For a quick mini card or ornament, the allowance can be different. Check the finishing method before cutting expensive or hand-dyed fabric.

To calculate cutting size, add the border twice—once for each side:

Fabric width to cut = stitched width + (2 × margin per side).
Fabric height to cut = stitched height + (2 × margin per side).

Using the 112 × 84-stitch chart on 14-count Aida from the earlier example, with a 3-inch margin all around, the cloth should be at least 14 × 12 inches (8 + 6 = 14 inches wide; 6 + 6 = 12 inches high). For the same chart with a 2-inch border, the cut size would be 12 × 10 inches.

These are minimum planned cutting dimensions for the chosen border, not an exact requirement for every finishing technique. If you intend to lace the embroidery around a substantial backing board, consider whether more cloth is needed.

Reusable cross stitch fabric-size worksheet

Write these five numbers on paper or in a note before starting each new chart:

1. Chart width: ______ stitches
2. Chart height: ______ stitches
3. Fabric count: ______ stitches per inch
4. Border: ______ inches per side
5. Finished fabric cut: (width ÷ count + 2 × border) by (height ÷ count + 2 × border) inches

Worked worksheet: If you have an 84 × 70-stitch motif, 14-count Aida and a 2.5-inch margin, your stitched area is 6 × 5 inches and the planned cloth cut is 11 × 10 inches. Double-check the real size of your purchased piece of Aida, especially when cutting several motifs from one sheet.

For a 50 × 50-stitch mini design on 18-count, the stitched area is approximately 2.78 × 2.78 inches. With a 2-inch margin, cut at least approximately 6.78 × 6.78 inches. In practice, round the fabric dimensions up to a convenient measurement, never down.

Linen and evenweave: stitching over two threads

Fabric thread count is not always the same as stitches per inch. On 28-count evenweave worked over two fabric threads per cross stitch, you make approximately 14 crosses per inch—the equivalent stitched scale of 14-count Aida. On 32-count evenweave stitched over two, you make approximately 16 crosses per inch.

If you choose to stitch over one fabric thread, use the full fabric count instead. Always check the pattern’s instruction for stitching over one or over two before calculating. A design worked over one on 28-count linen comes out half the width and height of the same design worked over two.

Common sizing mistakes to avoid

Confusing the design area with the cutting area

The stitched dimensions exclude mounting allowances. Calculate your preferred finish before cutting. For a traditional framed piece, see how to frame cross stitch.

Using a photographed hoop as a ruler

Mockups often show a styled hoop and do not give an exact measurement. Trust the stitch count and fabric count in the actual chart, and check whether the designer includes border stitches.

Forgetting fractional and specialty stitches

A chart’s stated width in stitches still determines the pattern’s span. Fractional stitches inside its grid usually do not extend its overall dimensions, but unusual finishing or stitched borders might. Use the designer’s declared chart dimensions when available.

Cutting before confirming orientation

A wide rectangular chart on a narrow strip of Aida may physically fit only when the fabric is rotated. Check both the stitched size and the required borders before making the first cut.

Frequently asked questions

How big is 100 stitches on 14-count Aida?

One hundred full stitches across measure about 7.14 inches, or 18.14 cm. Remember to add extra material on both sides for framing or finishing.

Does 18-count Aida use more stitches?

No. The chart has the same number of stitches, but those crosses fit into a smaller physical area.

Can I use this calculation for a cross stitch bookmark?

Yes. First calculate the stitched size, then use the extra margin required by your particular bookmark finishing method, which may be smaller than a framed design’s margin.
