Quilting Fabric Requirements: Every Size From Crib to King, With Backing, Binding & Batting

Stop guessing how many fat quarters or jelly rolls you need. Exact yardage for quilt tops, backing, and binding for all six standard sizes — plus the precut math that saves time and money.

Standard Quilt Sizes and Top Yardage

Quilt top yardage depends heavily on your block design, but these estimates cover a standard patchwork or simple block pattern using 45" wide quilting cotton. For intricate paper-pieced designs with many small pieces, add 20–30%.

Quilt Size Dimensions Top Yardage (45" fabric) Fat Quarters Needed
Crib / Baby45" × 60"3.5 – 4.5 yd12 – 18
Throw / Lap60" × 72"5.0 – 6.5 yd20 – 30
Twin72" × 90"6.5 – 8.0 yd28 – 40
Full / Double84" × 90"7.5 – 9.5 yd35 – 48
Queen90" × 108"9.0 – 11.5 yd42 – 60
King108" × 108"11.0 – 14.0 yd50 – 72

Top yardage is total fabric across all colors. If using 12 different fabrics for a throw quilt, divide the total yardage by 12 to get roughly 0.5 yard per fabric.

Precut Guide: What Each Pack Contains

Precuts save cutting time and give you a coordinated palette without buying full yardage of every color. Here is what is inside each pack:

Precut Name Piece Size Pieces per Pack Total Yardage Equivalent Best For
Fat Quarter18" × 22"Varies (often 20–40)~0.25 yd per pieceSampler quilts, scrappy projects
Fat Eighth9" × 22"Varies~0.125 yd per pieceSmall pieces, accent blocks
Jelly Roll2.5" × WOF (~44")40 strips~2.75 yd totalStrip quilts, log cabin, bargello
Layer Cake10" × 10"42 squares~2.75 yd totalSquare-based blocks, half-square triangles
Charm Pack5" × 5"42 squares~0.75 yd totalPostage stamp quilts, baby quilts

A single jelly roll (40 strips) and a background fabric (2–3 yards of solid) can make a throw-size quilt top. Two jelly rolls or a jelly roll plus a layer cake will get you to twin size. For queen and king, you will need yardage.

Backing Calculation: Width ÷ 40 × Length ÷ 36

Quilt backing needs to extend 4–8 inches beyond the quilt top on all four sides (for the longarm quilting frame). The formula:

Backing Yardage = Ceiling( (Quilt Width + 8") ÷ 40" ) × (Quilt Length + 8") ÷ 36"

Using 40" as the usable width of standard 44/45" quilting cotton (after selvedge removal). For 108" wide backing fabric, skip the ceiling division — one width covers everything up to a king.

Quilt Size Backing (45" fabric, seamed) Backing (108" wide fabric)
Crib (45×60)1.75 yd1.75 yd
Throw (60×72)4.00 yd2.25 yd
Twin (72×90)5.50 yd2.75 yd
Full (84×90)8.00 yd2.75 yd
Queen (90×108)8.50 yd3.25 yd
King (108×108)10.00 yd3.25 yd

108" wide backing is the clear winner for throw quilts and larger. At roughly double the per-yard price of standard 45", it costs more per yard but uses far fewer yards — often breaking even or saving money on twin and larger quilts.

Binding: Perimeter ÷ 40 × Width of Fabric

Binding wraps the raw edges of the quilt. The standard method uses 2.5" wide strips cut across the width of the fabric, joined end-to-end, folded in half, and stitched to the quilt edge. The formula:

Binding Strips Needed = Ceiling( (2 × Width + 2 × Length + 12") ÷ 40" )
Binding Yardage = Strips Needed × 2.5" ÷ 36"

The extra 12" covers corner mitering and the joining seam. For a throw quilt (60" × 72"): perimeter = 264", total needed = 276", strips = Ceiling(276 ÷ 40) = 7 strips, yardage = 7 × 2.5 ÷ 36 = 0.5 yard. Most quilters buy 5/8 yard (0.625) for throw-size binding to have a safety margin.

Batting Sizes

Batting should extend 2–4 inches beyond the quilt top on all sides. Standard packaged batting sizes:

Batting Size Fits Quilt Up To Typical Fiber
45" × 60"CribCotton, cotton-poly blend
60" × 72"ThrowCotton, wool, bamboo
72" × 90"TwinCotton, 80/20 blend
90" × 96"FullCotton, wool
90" × 108"QueenCotton, wool, bamboo
120" × 120"KingCotton, 80/20, wool

How Many Precuts for Each Quilt Size

Quilt Size Jelly Rolls (40 strips) Layer Cakes (42 squares) Charm Packs (42 squares)
Crib112
Throw1 + 2 yd solid1 + 1.5 yd solid3
Twin225+

For queen and king quilts, precuts become impractical — buy yardage and cut your own strips and squares. A king quilt top at 108" × 108" uses roughly 12 yards of assorted fabrics, equivalent to 4+ jelly rolls or layer cakes.
