Measure fabric needs, layout efficiency, repeats, and costs. Build smarter sewing, upholstery, drapery, and craft plans with clean estimates today.
This single-column page uses a responsive three, two, and one-column input grid across large, medium, and mobile screens.
| Project | Piece Size | Fabric Width | Quantity | Repeat | Waste | Estimated Yardage |
|---|---|---|---|---|---|---|
| Curtain Panels | 90 x 50 in | 54 in | 2 | 6 in | 10% | 6.38 yd |
| Dining Chair Seats | 20 x 20 in | 54 in | 6 | 0 in | 8% | 2.13 yd |
| Quilt Backing | 96 x 96 in | 108 in | 1 | 0 in | 5% | 2.88 yd |
1. Adjusted cut width = piece width + (2 × seam allowance)
2. Adjusted cut length = piece length + hem allowance + extra margin
3. Pattern adjustment = round adjusted cut length up to the next pattern repeat when directional matching is enabled.
4. Panels per width = floor(fabric width ÷ adjusted cut width)
5. Required runs = ceil(total pieces ÷ panels per width)
6. Base required length = required runs × adjusted cut length
7. Total required length = base required length + waste allowance
8. Yardage = total required inches ÷ 36
9. Cost = rounded order yardage × price per yard, plus lining, minus discount, then plus tax.
This tool helps estimate yardage for curtains, upholstery, table runners, bedding, cushions, and craft work. It handles allowances, pattern repeat, lining, waste, pricing, and project efficiency in one place. That makes it more practical than a basic length-times-width estimator.
Many sewing projects need 5% to 15% extra. Use more when prints must align, fabric shrinks, or cutting layouts are tight. Large repeats and upholstery projects usually need the highest safety margin.
Pattern repeat forces each cut to begin at a matching motif position. That often means rounding panel lengths upward, which adds fabric even when finished dimensions stay unchanged.
Enter the actual usable roll width from the supplier specification. Common widths include 44, 54, and 108 inches. Always confirm usable width, not just nominal width.
For many curtains and drapery panels, lining yardage closely matches the main fabric. Some projects need less due to different hems, pleats, or construction methods.
Yes. It works for quilt backing, borders, binding estimates, and repeated cut sets. Just enter finished piece size, quantity, allowances, and waste assumptions carefully.
Fabric is often sold in practical increments. Rounding to one-eighth yard gives a realistic purchase amount while still keeping the estimate fairly precise.
Efficiency compares the useful covered area against the total ordered area. Higher percentages mean less implied offcut and better cutting layout performance.
Yes, especially for cushions, seat pads, and repeated upholstery panels. For complex furniture shapes, use it as a planning estimate before final cutting layouts.
