Quilt size chart

Keep mattress dimensions separate from illustrative quilt-size examples.

Bed-size examples

A size name is a starting point. The quilt column below uses an example with a 12 in drop on three sides and no pillow tuck. It is not the size of your measured quilt top.

What the examples include

The 12 in drop adds 24 in across the mattress and 12 in at the foot. Pillow-tuck examples use a different coverage target. A different drop, tuck or mattress depth changes the target; measure the intended coverage rather than assuming every “Queen” pattern uses the same dimensions.

Backing presets use a separate set of example dimensions. Choose a pattern or measured target; do not interchange the examples silently. The backing guide explains that distinction.

Baby, lap and throw quilts

These names do not determine a single required rectangle. Use your pattern’s intended dimensions or a measured quilt top. No fixed size is assigned here, and a crib mattress dimension is not automatically a quilt-top measurement.

Measure before planning fabric

Mattress size
A bed-planning reference, not a fabric cut size.
Quilt top size
The assembled top before layering; the default backing-calculator input.
Finished quilt size
The intended completed quilt size; select that basis explicitly if using it to plan.
Backing and batting
Separate layers with their own overhang. Confirm the requirements for your project.

The calculator starts with custom measurements. Opening it from this chart does not transfer mattress dimensions or silently select a preset.
