Quilt border yardage plan

Plan straight, butted quilt borders from the center measurements, strip widths, and usable WOF.

Measurements

Editable example inputs. Adjust them for your project.

Enter actual dimensions before borders. Some methods average measurements taken in several places; calculate that average before entering it. The page does not ease or remeasure between layers.

Border 1

Optional bolt label only. Enter measured usable width separately; no width is filled or deducted automatically.

Apply one to three rows from inner to outer. The method attaches side borders first, then top and bottom. Rows with the same fabric name must use the same usable WOF and purchase increment; theoretical yardage is summed before one purchase rounding. Mitered corners, diagonal joins and cutting waste are not modeled.

Input guidance and units

Enter inches unless a field says otherwise. The result keeps the theoretical quantity separate from purchase rounding.

Enter fractional inches as decimals: 1/8 = 0.125, 1/4 = 0.25, 1/2 = 0.5. Dimensions and yard increments use steps of 0.125; counts use whole numbers. Fraction text such as 1/8 is not accepted in number fields.

What this calculator answers

This plan adds one to three straight, butted border layers from the quilt-center dimensions, attaching the two side borders before the top and bottom borders.

How to use it

  1. Measure the quilt center before adding borders.
  2. Add one to three border rows from inner to outer and name each fabric.
  3. Enter finished border width, usable WOF and seam allowances.
  4. Specify any end-cutting allowance and purchase increment, then review each layer and fabric total.

Formula and variables

Cut strip width = finished border width + 2 × border-to-center seam allowance. Side cut length = current length + 2 × end allowance. Top/bottom cut length = current width + 2 × finished border width + 2 × end allowance. Yardage = total WOF strips × cut strip width ÷ 36.

Independent example

60 × 72 in center; one 4 in finished border; 1/4 in attachment and strip-join seams; 42 in usable WOF; no end allowance.

Cut width = 4 + 0.5 = 4.5 in. Side pieces are 72 in and top/bottom pieces are 68 in; each exceeds 42 in, so each of four pieces uses two WOF strips: 8 strips total. Yardage = 8 × 4.5 ÷ 36 = 1 yd.

  • 8 WOF strips
  • 1 yd theoretical yardage
  • 1 yd recommended purchase

What the result means

Finished dimensions grow by twice the finished border width at each layer. The model does not calculate mitered corners or mixed-cut nesting.

Common questions

Does this include cutting waste?

Only the allowances named in the inputs are included. The calculation does not infer scrap reuse or an extra waste percentage.

Are the result and purchase amount the same?

Theoretical material required and a recommended purchase quantity are different. A purchase amount is shown only when the method supports it and its rounding choice is supplied.

Method notes and unresolved issues

Use measured usable dimensions and the construction method named on this page. Example inputs are optional and are not universal standards.
