Fabric Yardage for Quilts: From Throw to King Size

> **Quick Answer:** A queen-size quilt (90×100 inches) needs approximately 8–9 yards of 44-inch fabric for the top, 8 yards for the backing (or 3 yards of 108-inch wide backing), and ¾ yard for binding. Add 10–15% extra for cutting waste. Use our [quilt fabric calculator](/fabric-calculator) to get exact yardage for your size.

Quilt yardage is one of those deceptively simple calculations that turns complicated fast. A single-fabric quilt top is straightforward — but the moment you add a pieced design, borders, and binding, you're tracking six or eight separate fabric requirements. Then there's backing, which needs entirely different math.

This guide covers yardage for every standard quilt size and every major component: top, backing, and binding. It also covers the common traps that leave quilters short on fabric mid-project.


Standard Quilt Sizes and What They Mean

Before you calculate anything, confirm your target size. Quilt dimensions vary based on how you're using the quilt:

| Quilt Size | Finished Dimensions | Common Use |

|-----------|--------------------|-|

| Throw | 50×65 inches | Sofa, lap quilt |

| Twin | 60×80 inches | Single bed with minimal drop |

| Full | 80×90 inches | Full/double bed |

| Queen | 90×100 inches | Standard queen (6-inch drop) |

| King | 108×108 inches | Standard king |

"Drop" refers to how far the quilt hangs over the side of the mattress. A 6-inch drop on a queen mattress (60 inches wide) adds 12 inches to the finished width (6 inches per side). If you want a pillow tuck at the top — tucking the quilt under pillows — add another 10–12 inches to the length.

For a queen bed with a generous drop (10 inches per side, 12-inch pillow tuck), your finished quilt is 80×112 inches, which is substantially more fabric than the "standard" 90×100.

Fabric Yardage for the Quilt Top

For a simple, single-fabric quilt top, use this formula:

```

Fabric Width Panels = ceil(Quilt Width ÷ Usable Fabric Width)

Total Inches = Cut Length × Width Panels

Total Yards = Total Inches ÷ 36

```

With 44-inch quilting cotton (usable width is about 42 inches after trimming selvages), a 90-inch wide quilt top needs 3 width panels. At 100 inches per panel (plus ¼-inch seam allowances on each side), that's approximately 8.5 yards.

For pieced quilt tops, every fabric in the design gets calculated separately based on the cutting plan. A simple 9-patch block in two fabrics is easy. A Wedding Ring or Flying Geese pattern with 8–12 fabrics means 8–12 separate yardage calculations. Most quilt patterns include yardage requirements — use them as your starting point, not your final number.

**Always add 10–15% extra for pieced quilts.** Small cutting errors compound across hundreds of blocks. Running out of the fabric for your center medallion is a disaster. Most experienced quilters add at least ¼ yard to every fabric in a pattern that has many pieces.

Our [fabric calculator](/fabric-calculator) calculates yardage for rectangular quilt tops. For complex pieced patterns, use the pattern's requirements and add your buffer.

Backing Fabric: The Calculation Most Quilters Get Wrong

Quilt backing is the area where miscalculation is most expensive because backing fabric is typically sold in a continuous cut. There are three approaches:

Option 1: Standard 44-inch Quilting Cotton

For quilts wider than about 40 inches (which is basically every quilt larger than a wall hanging), you need to seam two or three lengths of backing fabric together.

For a 90-inch wide quilt, you need three widths of 44-inch fabric seamed together (3 × 42 usable inches = 126 inches, enough for 90-inch quilt with ease). Each panel needs to be as long as the quilt plus 4–6 extra inches of ease per side for squaring up and quilting.

For a 90×100-inch quilt, backing calculation:

- Panels needed: 3 (to span 90 inches)

- Length per panel: 100 + 8 (ease) = 108 inches

- Total yardage: (108 × 3) ÷ 36 = **9 yards**

Most quilting guides quote 8 yards for a queen backing. Nine yards gives you the full ease you need.

Option 2: Wide Backing Fabric (108 inches)

Wide backing fabric eliminates the center seam and uses dramatically less yardage. At 108 inches wide, a 90-inch-wide quilt needs only one panel width.

- Length needed: 100 + 8 (ease) = 108 inches

- Total yardage: 108 ÷ 36 = **3 yards**

Three yards of 108-inch backing fabric versus nine yards of 44-inch fabric. The wide backing typically costs more per yard, but the total cost is often comparable — and you gain time not sewing the backing seam. Our [guide to fabric bolt widths](/blog/fabric-bolt-widths-explained) covers where to buy wide backing and what to look for.

Option 3: Horizontal Seams

For tall quilts that are narrower in width, a horizontal seam may waste less fabric. Calculate which orientation uses fewer panels for your specific dimensions. The [fabric calculator](/fabric-calculator) always calculates based on the orientation you enter.

Binding Fabric

Binding is the narrow fabric strip that wraps around the quilt's raw edges. It's the finishing touch — and many quilters forget to add it to their fabric order until the quilt is sandwiched and quilted.

Standard binding is cut 2.5 inches wide on the straight grain (or 2.25 inches for a narrower finished edge). To calculate:

1. **Quilt perimeter:** Add all four sides. For a 90×100-inch quilt: (90 + 90 + 100 + 100) = 380 inches of binding strip needed, plus 12–15 extra for joining and corners.

2. **Strips from fabric:** A 44-inch fabric width gives you about 42 usable inches per strip cut across the width. For 395 inches total, you need ceil(395 ÷ 42) = 10 strips.

3. **Yardage:** 10 strips × 2.5 inches = 25 inches = just under **¾ yard**

A ¾-yard cut is standard for binding a queen quilt. Buy a full yard if you want extra.

Pre-Washing: Add 5% to Your Calculations

Quilting cotton shrinks. Cotton pre-washed in hot water and dried in a hot dryer typically shrinks 2–3% in length and 1–2% in width. On 8 yards of backing, 3% shrinkage is 8.6 inches — almost a full quarter yard lost to the wash.

For quilts where you plan to wash the fabric before cutting (recommended for cotton quilts that will be laundered), add 5–8% to your calculated yardage.

If you plan to wash the finished quilt without pre-washing the fabric first (some quilters prefer the slight "crinkled" look of a quilt that shrinks after quilting), you can skip the extra yardage — but know your quilt will shrink slightly on first wash.

Our [fabric shrinkage guide](/blog/fabric-shrinkage-guide) covers how much different fabrics shrink and when pre-washing is mandatory versus optional.

Quick Reference: Yardage by Quilt Size

For standard single-fabric tops with 44-inch quilting cotton (add 10–15% for pieced designs):

**Throw Quilt (50×65 inches)**

- Top: ~3.5 yards

- Backing (44-inch): ~4 yards (2 panels, horizontal seam)

- Binding: ½ yard

**Twin Quilt (60×80 inches)**

- Top: ~4.5 yards

- Backing (44-inch): ~5 yards (2 panels)

- Binding: ⅝ yard

**Full Quilt (80×90 inches)**

- Top: ~7 yards

- Backing (44-inch): ~8 yards (3 panels)

- Binding: ¾ yard

**Queen Quilt (90×100 inches)**

- Top: ~8.5 yards

- Backing (44-inch): ~9 yards (3 panels)

- Binding: ¾ yard

**King Quilt (108×108 inches)**

- Top: ~12 yards

- Backing (44-inch): ~12 yards (3 wide panels)

- Binding: 1 yard

Avoid These Quilting Fabric Mistakes

**Buying the exact amount.** Quilting seam allowances are only ¼ inch, and small cutting errors across 200+ pieces add up. Always buy at least ¼ yard extra per fabric.

**Forgetting the backing is wider than the top.** Add 4–6 inches on each side to the backing dimensions, not just the finished quilt dimensions. The backing must extend beyond the quilt sandwich for the quilting frame.

**Miscounting piecing strips.** If a pattern says "cut 40 rectangles from Fabric A," verify how many rectangles you get from a 42-inch-wide strip at the specified cut size before buying.

**Not pre-washing.** For a quilt you'll wash, failing to pre-shrink can warp even a perfect quilt top after first wash. Read more about [avoiding common quilting mistakes](/blog/quilting-fabric-mistakes).

Calculate Your Exact Quilt Yardage

Enter your quilt's finished dimensions into the [fabric yardage calculator](/fabric-calculator) for top, backing, and binding separately. Each component gets its own calculation — different fabric widths, different seam allowances, different totals. Getting it right before you shop saves trips, money, and frustration.
