How to Calculate Fabric Size for Cross Stitch in 3 Steps

Updated: May 26, 2026

What You Need Before You Start

To calculate your fabric size, you need two numbers from your cross stitch pattern:

Stitch count — the number of stitches wide and tall. Usually written as something like “140w × 100h” or “Stitch count: 140 × 100.” Find it on the pattern cover, in the kit description, or in your design software’s project properties.
Fabric count — the number you plan to stitch on (e.g. 14-count Aida, 28-count linen). This is a choice you make based on the detail level and final size you want.

You do NOT need to measure anything or do any cutting yet — just collect those two numbers.

Step 1: Divide Stitch Count by Fabric Count

This gives you the finished size of the stitched area (excluding border fabric).

Formula:

Finished width  = Pattern stitches wide  ÷ Effective count
Finished height = Pattern stitches tall  ÷ Effective count

What is effective count? For Aida, it’s just the count (14-count Aida = 14). For linen or evenweave stitched over 2 threads, divide by 2 first (28-count linen ÷ 2 = 14 effective).

Example — 14-count Aida, 140 × 100 stitch pattern:

Finished width  = 140 ÷ 14 = 10 inches
Finished height = 100 ÷ 14 = 7.14 inches

Same pattern on 28-count linen over 2:

Effective count = 28 ÷ 2 = 14
Finished width  = 140 ÷ 14 = 10 inches  (same)
Finished height = 100 ÷ 14 = 7.14 inches (same)

The finished stitch size is identical. The fabric just looks and feels different.

Step 2: Add Your Border

Never cut your fabric to the finished stitch size. You need extra fabric around the edges to:

Mount it in a hoop or frame while stitching
Allow for framing or finishing
Prevent the design from being cut off

Standard border: 3 inches on each side. For large pieces going into stretcher bars, use 4–5 inches.

Formula:

Fabric to buy width  = Finished width  + (border × 2)
Fabric to buy height = Finished height + (border × 2)

Example continued (3-inch border):

Fabric to buy width  = 10 + (3 × 2) = 16 inches
Fabric to buy height = 7.14 + (3 × 2) = 13.14 inches

Round up to the nearest half-inch when buying. Buy at least 16” × 14” for this example.

Step 3: Choose a Hoop or Frame

Your hoop or frame must be large enough that the design fits comfortably inside it with room to grip the fabric at the edges.

Rule: Hoop diameter ≥ max(finished width, finished height) + 3 inches

For the 10” × 7.14” example:

Max dimension = 10”
Minimum hoop = 10 + 3 = 13”
Choose a 14-inch hoop or a Q-Snap frame

Standard hoop sizes: 4”, 5”, 6”, 7”, 8”, 9”, 10”, 12”, 14”, 18”

For large projects (wider than 12 inches), consider a Q-Snap frame or scroll frame instead of a round hoop. These apply even tension across the fabric and avoid the hoop marks that appear on Aida.

Worked Example: Full Calculation

Pattern: 200w × 150h stitches Fabric: 18-count Aida (over 1) Border: 3 inches

Effective count     = 18 (Aida, over 1)
Finished width      = 200 ÷ 18 = 11.11 inches (28.2 cm)
Finished height     = 150 ÷ 18 = 8.33 inches (21.2 cm)
Fabric width to buy = 11.11 + 6 = 17.11 inches → buy 18 inches
Fabric height to buy= 8.33 + 6 = 14.33 inches → buy 15 inches
Hoop recommendation = max(11.11, 8.33) + 3 = 14.11" → use 18" hoop or scroll frame

Metric Version

If you work in centimetres:

Finished size (cm) = (Stitch count ÷ Effective count) × 2.54

Example: 140 stitches on 14-count:
(140 ÷ 14) × 2.54 = 10 × 2.54 = 25.4 cm

Add 7.5 cm of border on each side (equivalent to 3 inches).
