How do you calculate fabric yardage for a project?
List each rectangular cut piece with its width across the fabric, length along the roll and required count. Enter usable fabric width, seam and cutting allowance, pattern repeat and purchase increment. The worksheet counts whole pieces across a row, then whole rows along the roll, and converts their total length to linear yards. This is fabric yardage, a length of cloth; bulk cubic yards belong in the cubic yard calculator.
What does fabric width mean in a yardage estimate?
Fabric width is the usable crosswise width of the bolt after excluding selvage or flaws. For a cut width of 20 in on a 54 in usable fabric, floor(54 ÷ 20) = 2 pieces fit side by side. A third cannot fit even if the total area seems sufficient. Enter the actual usable width supplied for the product.
How do you count rows for repeated cuts?
For one piece type, pieces per row = floor(usable width ÷ cut width). Rows = ceil(piece count ÷ pieces per row). Multiply rows by the cut length to find its required length along the roll. Different piece types are counted in separate rows. This is intentionally conservative and does not combine unlike pieces or optimize offcuts.
Pieces per row = ⌊usable fabric width ÷ cut width⌋
Rows = ⌈quantity ÷ pieces per row⌉
Linear length = rows × cut length
How are seam and cutting allowances added?
Enter the extra material on each side of every piece. Twice that value is added to both the finished width and finished length. For a 20 × 30 in finished piece with 0.5 in on every side, the raw cut is 21 × 31 in. Add other project-specific hems, pleats, wraparound or upholstery boxing as separate measurements before estimating.
How does vertical pattern repeat change the cut length?
When the print has a vertical repeat, each raw cut length is rounded up to the next repeat multiple: ceil(raw length ÷ repeat) × repeat. This reserves material for one alignment strategy but does not guarantee a matched seam between different pieces. Horizontal repeat and directional motif placement need a manual cut plan.
Can pieces be rotated to fit across the bolt?
This worksheet holds the entered piece width across the fabric and length along the roll. It does not rotate pieces because nap, grain, directional print and stretch can prevent rotation. If rotation is acceptable for the actual material, change the piece orientation explicitly and calculate again; check construction requirements first.
How do yards, inches, meters and centimeters convert?
One yard is 36 inches and exactly 0.9144 meters. Choose inches or centimeters for piece measurements; the result shows linear yards and meters. Unlike square yards or cubic yards, fabric yardage assumes a fixed usable fabric width, so it is a measure of the length ordered from the bolt.
What happens when a cut is wider than the fabric?
If the cut width including allowances exceeds usable fabric width, no full piece fits across the bolt. The calculator stops rather than dividing square area and inventing a workable layout. Split the piece with a planned seam or choose wider fabric, then enter the revised pattern pieces separately.
What does a fabric cutting example look like?
- Use a 54 in usable fabric and four finished pieces 20 in wide by 30 in long.
- Add 0.5 in to each side, yielding 21 in cut width and 31 in base cut length.
- Two pieces fit across, requiring two rows.
- Without a pattern repeat, 2 × 31 = 62 in, or 1.72 linear yd before extra allowance and purchase rounding.
How should you plan a directional print or nap?
Keep the fabric grain and print direction aligned along the roll for all pieces. The calculator does this by default. Mirrored cushion faces, large motifs and pile fabrics can need more yardage than rectangular packing suggests. Test a scaled cutting diagram or consult your upholsterer when matching is critical.
How are purchase increments and cost calculated?
After adding the separate piece-type row lengths, apply the entered percentage allowance and round up to the retailer’s allowed purchase increment, such as a quarter yard. Multiply purchased linear yards by your entered price per yard if provided. Taxes, shipping and labor are outside this subtotal.
Which related measurement tool should you use?
Use this page for cloth, curtains, cushions and upholstery cut pieces. For floor or wall surface coverage, use the square footage calculator. For soil, concrete or other bulk material volume in cubic yards, use the cubic yard calculator. The different units answer different purchasing questions.
