One finished size flows through the plan
Enter the finished centre dimensions, excluding its outer seam allowances. An optional border increases both dimensions by twice its finished width. Backing and binding then use that final size automatically. If you enter a complete quilt top, set border width to zero.
Follow a 48 × 60-inch project
A 4-inch border creates a 56 × 68-inch finished quilt. Four inches backing overhang gives a 64 × 76-inch target. At 42 inches usable backing width and ½-inch seam allowance per edge, the vertical plan needs two 76-inch cuts: 4.22 yards before extras. A 10% allowance rounded to quarter yards becomes 4.75 yards. The border uses six 4½-inch strips; binding uses seven 2½-inch strips under the default joining rules.
Keep different fabric purchases separate
The shopping list shows backing, binding and border fabric independently. It does not add their yardage into a misleading single cutting plan. Even if you use the same fabric for two parts, strip direction and offcut reuse need a combined cutting layout before reducing a purchase.
Read the seam diagram
The solid outline shows the required backing target. Dashed lines show joins between full-width panels in the selected orientation. The diagram is schematic, not a printable cutting pattern. Compare both directions and consider motifs, quilting requirements and where seams will fall.
Allowances and validation limits
Binding uses straight-grain strips with diagonal joins; borders use straight joins in a pieced continuous strip, sides first. The calculations have automated example and boundary checks, but the site does not claim independent quilter certification or physical fabric testing. Percentage extras are not a substitute for matching repeats, shrinkage checks or instructions from your quilter.
Questions, answered
Can I save the project?
Use Save this project for a browser-only draft, or download the project file. There is no account or cloud copy.
Why can the smaller yardage direction be unsuitable?
Directional prints or a quilter’s seam placement requirements can outweigh the arithmetic saving.
