Wall hangings, runners, and minis

Type	Common size range	Notes

Table Runner	14″ × 36″ to 16″ × 72″	Width typically 14–16″ (matching a place-mat row). Length follows your table.
Mini	12″ × 12″ to 24″ × 24″	Seasonal displays, gifts, and pattern testing. Quick to finish.
Pillow Cover (quilt-as-you-go)	20″ × 20″ to 22″ × 22″	Standard throw pillow insert is 18″; add 2-4″ for a snug cover.
Picnic / Outdoor	60″ × 80″ to 72″ × 90″	Equivalent to a twin. Use a more durable batting (polyester or wool).

Standard batting packages

Pre-packaged batting is sold in the sizes below. Your cut batting should be 4–6″ larger than your finished quilt top in each direction — check whether the package you own is large enough before you start.

Package name	Package size	What it fits
Crib / Baby	45″ × 60″	Baby/Crib quilt to 36″ × 54″ + 4-5″ overage
Craft / Throw	36″ × 45″ to 60″ × 60″	Minis, wall hangings, small throws
Twin	72″ × 90″	Twin (60×80) and smaller with room to spare
Full / Queen	90″ × 108″	Queen (90×108) with 0″ overage — buy up if you want margin
King	120″ × 120″	King and Cal King quilts with 6–12″ to spare

Use the Batting Calculator to check whether a specific package is large enough for your quilt, including overage.

How to choose your quilt size

The right size depends on how the quilt will be used. Bed quilts need enough drop to cover the sides of the mattress and tuck under pillows; lap quilts just need to wrap one person. Wall hangings follow your available wall space. Before picking a pattern, decide which size you are making — then run the calculators with those exact dimensions.

For bed quilts, measure your mattress (width × length) and decide how much you want hanging over the sides and foot. A common formula: quilt width = mattress width + 2 × side drop; quilt length = mattress length + foot drop + pillow tuck (usually 14–20″ at the top). The table above shows typical values; adjust for your preference.

For lap and throw quilts, 54″ × 72″ is the most common pattern size because it fits neatly from a single WOF cut and prints well in most pattern guides. If you are gifting the quilt or want something more generous, 60″ × 80″ works as a twin-size throw.

Quilt top vs. finished size

The sizes above are finished quilt dimensions — the size after quilting and binding. Your quilt top needs to be 1–2″ larger in each direction to allow for draw-up during quilting. Your batting cut size should be 4–6″ larger than the finished quilt in each direction (2–3″ per side). Your backing should be at least 4″ larger per side as well.

Run the individual calculators with your finished quilt dimensions and they will account for seam allowances, overage, and margins automatically:

Batting Calculator — finds the cut size and checks whether your package fits
Backing Calculator — calculates panels and yardage for WOF or 108″ wideback fabric
Binding Calculator — exact yardage and strip count for double-fold binding

Sizing for block-based patterns

Most patterns are built from a repeating block. If you are drafting your own layout, choose a target finished quilt size first, then work backward to find a block size that divides evenly — or accept sashing and borders to fill the gap.

For example: a Queen quilt (90″ × 108″) with 12″ blocks needs 7.5 × 9 blocks — not whole numbers. Options: use 4″ sashing to make the blocks work (7 blocks + 6 × 4″ sashing + borders), or change the block size to 9″ (10 × 12 = 90 × 108, exact), or add borders to a smaller layout. The Border Calculator handles the border math once your block layout is settled.
