How Big Is a 300 × 400 Cross Stitch Pattern?
A 300 × 400 chart measures 21.43 × 28.57 inches (54.43 × 72.57 cm) on 14ct Aida, before borders. The example cut is 27.43 × 34.57 inches. Check the cloth’s measured usable width and height together, and plan how you will support and work across the larger area.
A 300 × 400 cross-stitch pattern measures 21.43 × 28.57 inches (54.43 × 72.57 cm) on 14ct Aida. On 16ct it is 18.75 × 25.00 inches (47.63 × 63.50 cm), and on 18ct it is 16.67 × 22.22 inches (42.33 × 56.44 cm). These are stitched dimensions; the table adds an explicit 3-inch planning margin on every side.
Treat the cloth, display and working area as separate decisions
A seller’s precut name does not establish usable dimensions. Compare the measured cut against the required rectangle, including allowances. For roll fabric, confirm which measurement is usable width and which is the length supplied.
Enclosing the entire 14ct design in a circular opening requires a design diagonal of about 35.71 inches. That is a geometric comparison, not a requirement to use such a large working hoop. A smaller working frame can be repositioned as you stitch successive sections.
Two decisions for this project
Full-coverage example: establish the thread model before separating shades
A filled rectangle contains 120,000 full crosses. On 14ct with 2 strands and the calculator’s existing standard usage setting, the estimate is 67.45 pooled skein equivalents. At 70% assumed coverage it becomes 84,000 crosses and 47.22 equivalents.
For a full-coverage chart, do not apply the lower-coverage scenario just to reduce the shopping estimate. Count each shade where possible; confetti, blending, backstitch and rework can change actual consumption. The combined result cannot guarantee any color’s supply.
Display example: test 18ct against an 18 × 24 inch opening
The 18ct design is 16.67 × 22.22 inches. An illustrative 0.50 inch visible border expands it to 17.67 × 23.22 inches, which fits the measured opening. With 3.00 inches per side beyond that for finishing, the nominal cut is 23.67 × 29.22 inches.
Confirm the mount and overlap independently. A successful display-area comparison does not verify the frame’s clamp space or the cloth needed behind the mounting board.
300 × 400: design, fabric cut and working opening
Measurements use nominal count, then convert unrounded inches with 1 in = 2.54 cm. Display rounds half-up to two decimal places. Every cut on this page adds only 3 in per side: visible border 0 + finishing allowance 3. The main calculator normally starts with a separate 1.5 in border plus 3 in finishing; the links here explicitly select this table’s 0 + 3 example. Actual cloth, clamps, seams, mats and mounting may need different allowances.

The hoop diagonal and rectangular opening checks reuse the existing hoop calculator. Values describe an opening enclosing the entire design at once, rounded for display; measure beyond the exact unrounded requirement. A smaller working hoop or frame can be moved. Q-Snap’s nominal outside size is not its usable opening, and this table does not certify clamp clearance or enough mounting cloth.
Worked example: 300 × 400 on 14ct Aida
- Use 14ct Aida over one: effective count = 14 ÷ 1 = 14 stitches per inch.
- Stitched width = 300 ÷ 14 = 21.43 inches; stitched height = 400 ÷ 14 = 28.57 inches.
- Add 3 inches on each side: width = 300 ÷ 14 + 6 and height = 400 ÷ 14 + 6, giving a nominal 27.43 × 34.57 inch cut.
- Multiply the unrounded inch dimensions by 2.54: the design is 54.43 × 72.57 cm and the nominal cut is 69.67 × 87.81 cm. Check actual fabric and finishing requirements before cutting.
Full crosses and estimated DMC skein equivalents
A completely filled 300 × 400 rectangle has 120000 full crosses. The second row assumes 70% coverage; it is an illustration, not a measured chart count.

Both rows call the live calculator’s existing planning function: 14ct, two strands, standard mixed-pattern usage and the same skein-utilization assumptions. No new yield or waste coefficients are introduced. Pooled equivalents are not a per-color shopping list: estimate and round each color separately. Half stitches, backstitch, blending and rework can change usage. See the existing DMC stitches-per-skein model and limitations.

Questions about this size chart
Must my working hoop hold the whole large picture at once?
No. The whole-design opening is a geometry reference. You can move a smaller working hoop or frame between sections; support the loose cloth and follow the hardware’s handling guidance.
Does the pooled estimate guarantee enough thread for a confetti-heavy chart?
No. It uses the existing model’s stated assumptions, not a measured yield for your chart. Separate the colors, check the pattern’s thread information and adjust the existing usage setting when your project warrants it.
Can an 18 × 24 frame show this chart on 18ct?
The 16.67 × 22.22 inch image fits geometrically. With the example 0.50 inch border, its 17.67 × 23.22 inch display area also fits that actual opening. Mounting cloth and mat overlap still need their own checks.
