📋 Quilt Size Reference Chart

A general reference for standard finished quilt dimensions by bed size. Exact sizes vary by pattern and personal preference for overhang.

Mattress, plus a drop on each side

None of these numbers is a mattress measurement. Each is a mattress with an overhang built in, and the width takes it twice:

quilt width  = mattress width  + (2 × drop)
quilt length = mattress length + foot drop + pillow allowance

Set the chart against standard US mattresses and the drop it assumes is consistent:

Size	Mattress	Quilt	Drop per side
Twin	38 × 75	70 × 90	16 in
Full	54 × 75	80 × 90	13 in
Queen	60 × 80	90 × 90	15 in
King	76 × 80	108 × 92	16 in

Adjusting the chart to a real bed

Measure from the top edge of the mattress to where you want the quilt to stop, double it, and add it to the mattress width. A deep pillow-top can be 16 in thick on its own, swallowing the whole drop these sizes assume. Lap and crib quilts are not tied to a bed at all, so treat 36 × 52 and 50 × 65 as conventions.

These are finished sizes, measured after quilting. Dense quilting pulls a top in, and cotton batting shrinks on a first wash by the figure on the wrapper, so a top pieced to exactly 90 × 90 measures less by the time it reaches the bed. Piece a little over if the final size matters.

Frequently asked questions

What size is a queen quilt?

90 × 90 in on this chart. A queen mattress is 60 × 80, so that is 15 in hanging down each side and 10 in at the foot, with the top edge left for a pillow tuck.

Why is the king quilt wider than it is long?

Because a king mattress is 76 in wide and only 80 in long, and the drop is added to both sides of the width but only the foot of the length. That turns 76 × 80 into 108 × 92.

How much overhang should a quilt have?

Whatever suits the bed. Around 13 to 16 in a side is what these sizes assume, which covers a standard mattress and box spring; a bed with a valance or a visible frame usually wants less.
