How to Calculate Fabric Yardage
The basic fabric calculation formula is: Yards = (Finished Length + Seam Allowances) × Number of Panels ÷ 36 for fabric wide enough to accommodate your finished width in one piece.
If your finished width exceeds the fabric width, you'll need multiple widths sewn together. The formula becomes more complex:
- Determine how many panels wide you need: ⌈(Finished Width + Seam Allowances) ÷ Fabric Width⌉
- Multiply by length per panel (finished length + hem/seam allowances)
- Add pattern repeat waste if applicable
- Convert inches to yards (÷ 36)
- Round up to nearest 1/8 yard (stores sell in 1/8 yd increments)
Common Fabric Widths Explained
| Width | Common Uses | Notes |
|---|---|---|
| 44–45" | Quilting cotton, craft fabric | Most common for quilting; usable width ~42" after selvedge |
| 54" | Home dec, upholstery, drapery | Decorator fabric standard |
| 58–60" | Apparel, knit fabrics, ponte | Good for clothing projects |
| 72" | Fleece, wide canvas | Useful for large single-piece projects |
| 108" | Quilt backing, wide sheets | Eliminates center seam in quilt backs |
Always subtract 1–2 inches from listed width for selvedge (the woven edge that can't be used). When calculating, use the usable width, not the full bolt width.
Pattern Repeat Calculations
Patterned fabric with a repeat requires extra yardage to ensure the pattern aligns across seams and panels. The pattern repeat is the distance between identical points in the pattern's repeat cycle.
Formula with pattern repeat:
Adjusted cut length = ⌈Finished Length ÷ Pattern Repeat⌉ × Pattern Repeat + Seam Allowances
Example: Curtain 84" long, 24" pattern repeat.
⌈84 ÷ 24⌉ = ⌈3.5⌉ = 4 repeats. Cut length = 4 × 24 = 96 inches (vs 84" without pattern matching).
Extra fabric needed: 96 − 84 = 12 inches per panel, or 1/3 yard extra per panel.
Large pattern repeats (12"–27") on multiple panels can add significantly to fabric requirements — one of the biggest sources of underestimation in home decorating projects.
Seam Allowances and Hems
Always add extra for seams and hems to your finished dimensions:
- Standard seam allowance: 5/8 inch (sewing), 1/4 inch (quilting)
- Hem allowances: 1–4 inches per hem depending on project
- Curtain headers: Add 4–8 inches for rod pocket or pleat header plus 4 inches bottom hem
- Quilts: Add 1/4 inch seams to all pieces; backing should be 2–4 inches larger than quilt top on all sides
The waste factor in this calculator accounts for seam allowances, hems, cutting inaccuracies, and shrinkage. For pre-washed fabric, use 10–15%. For unwashed fabric that may shrink, use 15–20%.
Pre-Washing Fabric: Should You?
Whether to pre-wash depends on the project:
- Always pre-wash for: Quilts and items that will be washed regularly; cotton fabrics (can shrink 3–5%); fabrics that bleed color
- Skip pre-washing for: Garments that will be dry-cleaned; display quilts not for use; fabric that loses special finishes when washed
- Pre-washing tip: Treat the fabric as you plan to launder the finished item. Wash in warm water, dry on medium heat. Press immediately after drying to prevent excessive wrinkling.
Cotton quilting fabric typically shrinks 2–4% in length and 1–2% in width. Pre-washing eliminates this concern and also removes sizing and chemical finishes.
Fabric Yardage for Common Projects
- Standard pillow cover (18×18"): 0.75 yard (44" fabric)
- Tablecloth (60×84"): 2.5–3 yards (60" fabric)
- Twin quilt top (60×80"): 4–6 yards total (multiple fabrics)
- Pair of curtain panels (50×84" each): 6–8 yards (54" fabric)
- Simple tote bag: 0.75–1 yard
- Child's dress: 1.5–2.5 yards
- Women's blouse: 2–2.5 yards (58" fabric)
- Chair seat cushion (18×18"): 0.75 yard
Buying Fabric: Tips and Tricks
- Buy more than you need: Always round up to the nearest 1/4 yard minimum. If dye lots differ, extra can't be matched later.
- Store fabric properly: Roll large pieces; fold smaller ones. Avoid long-term compressing at folds. Store away from light to prevent fading.
- Check for flaws: Inspect the full bolt for weaving errors, stains, or off-grain printing before cutting.
- Ask about remnants: Fabric stores often sell end-of-bolt remnants at a discount.
- Check grain: Fabric should be cut on-grain for garments to hang correctly. Check by pulling a thread horizontally to reveal the grain line.

Frequently Asked Questions
How many yards of fabric do I need for curtains?
For a pair of curtains (each panel 50" wide × 84" long): at 54" fabric, you need approximately 5–6 yards for 2 panels including hems and header. For patterned fabric with a 12" repeat, add 1–2 extra yards for matching.
How do I convert fabric measurements from inches to yards?
Divide inches by 36. Example: 108 inches ÷ 36 = 3 yards. Common conversions: 9" = 1/4 yd; 18" = 1/2 yd; 27" = 3/4 yd; 36" = 1 yd. Fabric stores sell in 1/8-yard increments (4.5 inches).
How much fabric do I need for a queen size quilt?
A queen quilt (90×108") requires approximately 7–10 yards total for the quilt top (including multiple fabrics), 8 yards for backing (2 lengths of 54" fabric seamed), and 3/4 yard for binding. Total project: 16–19 yards of fabric.
How do I calculate fabric for a tablecloth?
Finished size = table length + 2× drop + seams. For a 30×72" table with 12" drop: finished size = (30+24)×(72+24) = 54"×96". At 60" fabric, you need 96" + hems = ~108" = 3 yards.
What is the standard width of quilting fabric?
Standard quilting cotton is 44–45 inches wide, with a usable width of 42–43 inches after removing selvedges. Wide backing fabric is 108 inches wide and eliminates center seams in quilt backs.
How much extra fabric should I buy for a pattern repeat?
Add one full pattern repeat per panel/piece. For a 12" repeat with 4 curtain panels: add 4 × 12" = 48" = 1.33 yards extra. For large repeats (24"+), add up to 2 repeats to be safe with multiple panels.
How do I calculate fabric for upholstery?
For a standard armchair: 6–8 yards of 54" fabric. For a sofa: 12–16 yards. Always add 20–25% for pattern matching, tucking, and waste. Measure each piece separately (seat, back, arms, cushions) and account for fabric direction.
What does pre-shrunk mean for fabric?
Pre-shrunk fabric has been washed and dried by the manufacturer to minimize further shrinkage. Most commercial fabrics are not pre-shrunk. Cotton typically shrinks 3–5% when first washed. Pre-wash your fabric before cutting to prevent post-sewing shrinkage distorting your project.
How many yards in a bolt of fabric?
A standard bolt contains 15–30 yards of quilting cotton or apparel fabric. Decorator/upholstery fabric bolts are typically 10–15 yards. Fleece and other wide fabrics vary. Ask the fabric store how much remains on the bolt if you need a specific amount.
What is the difference between woven and knit fabric?
Woven fabrics (cotton, linen, canvas) don't stretch significantly — used for quilts, structured garments, home dec. Knit fabrics (jersey, ponte, spandex blends) stretch — used for T-shirts, leggings, stretchy garments. Most patterns specify which type is required.
