Understanding Quilt Dimensions
Why Quilts Are Bigger Than Mattresses
Standard quilt sizes are significantly larger than the mattresses they cover. This extra fabric serves several purposes:
- Side Drop: Covers the mattress depth (typically 10-15 inches)
- Decorative Overhang: Drapes attractively over the sides
- Pillow Coverage: Extends above the mattress to cover pillows
- Bottom Drop: Reaches toward or past the footboard
Calculating Your Perfect Quilt Size
To determine your ideal quilt dimensions:
- Measure your mattress: Length, width, and depth
- Add drop length: Add 15-20 inches to width for side drop
- Add top extension: Add 10-15 inches to length for pillow tuck
- Consider bed style: Platform beds need less drop than traditional beds

Baby & Crib Quilts (36" × 52")
Best for: Cribs, strollers, play mats, wall hangings
Fabric needs: 2-3 yards total for top, 1.5 yards backing, ⅜ yard binding
Tips: Perfect beginner project. Consider washability and softness. Avoid buttons or embellishments for safety.
Lap & Throw Quilts (50" × 65")
Best for: Couches, chairs, end-of-bed accents, gifts
Fabric needs: 3-4 yards total for top, 3.5 yards backing, ½ yard binding
Tips: Extremely popular gift size. Quick to make compared to bed quilts. Great for using bold patterns.
Twin Quilts (70" × 90")
Best for: Twin beds, guest rooms, kids' rooms, college dorms
Fabric needs: 5-6 yards total for top, 5.5 yards backing, ⅝ yard binding
Tips: Consider twin XL (70" × 95") for dorm beds which are typically longer.
Full/Double Quilts (85" × 90")
Best for: Full-size beds, older homes, antique beds
Fabric needs: 6-8 yards total for top, 7.5 yards backing, ¾ yard binding
Tips: Less common than queen but still widely used. Same length as twin but 15 inches wider.
Queen Quilts (90" × 95")
Best for: Queen beds (most common bed size in US)
Fabric needs: 7-9 yards total for top, 8.5 yards backing (pieced), ¾ yard binding
Tips: Most popular bed quilt size. Backing requires piecing (horizontal or vertical seam). Perfect balance of size and manageability.
King Quilts (110" × 95")
Best for: King beds, statement pieces, heirloom quilts
Fabric needs: 9-12 yards total for top, 10 yards backing (pieced), 1 yard binding
Tips: Large project requiring patience. Consider using a wider backing fabric (108" wide) to avoid piecing. Quilting requires a large space or longarm machine.
Batting & Backing Requirements
Batting Sizes
Batting should be 4-6 inches larger than your quilt top on all sides. Standard prepackaged batting sizes:
- Crib: 45" × 60"
- Twin: 72" × 90"
- Full: 81" × 96"
- Queen: 90" × 108"
- King: 120" × 120"
Backing Fabric Guidelines
Backing should also be 4-6 inches larger than your quilt top on all sides. For quilts wider than 40 inches (most quilts), you'll need to piece your backing:
- Standard fabric width: 42-44 inches
- Wide backing: 108 inches (available for large quilts)
- Piecing direction: Horizontal for wide quilts, vertical for long quilts
- Seam allowance: Use ½ inch seams when piecing backing
Custom Quilt Sizes
While standard sizes work for most projects, many quilters prefer custom dimensions:
When to Go Custom
- Deep mattresses: Pillow-top or memory foam beds need extra drop
- Unique beds: Antique beds, RVs, boats have non-standard sizes
- Design constraints: Block sizes might not fit standard dimensions evenly
- Personal preference: Want more or less overhang
- Wall quilts: Designed for display rather than bed coverage
Calculating Custom Sizes
For a custom quilt size:
- Measure mattress: W" × L"
- Measure mattress depth: D"
- Add side drop: W + (2 × desired drop) + 2"
- Add top/bottom: L + top tuck + bottom drop + 2"
Example: For a thick queen mattress (60" × 80" × 16" deep) with 18" side drop:
Width: 60 + (2 × 18) + 2 = 98"
Length: 80 + 12 + 18 + 2 = 112"
Custom quilt size: 98" × 112"
