Quilt backing yardage Plan standard-width backing from explicitly labeled quilt dimensions, overhang, and usable fabric width. Output: Panel count, cut dimensions, recorded nominal and usable widths, theoretical yardage, separate prewash purchase reserve, quantity including reserve, and recommended purchase quantity. Measured backing shrinkage adjustment Convert measured wash-test changes into a prewash backing size without assuming a universal fabric rate. Output: Measured length and width shrinkage, approximate adjusted prewash backing dimensions and explicit missing-axis status. No yardage or future-wash prediction. Wide-back fit check Check whether a wide-back fabric can cover the backing in one piece. Output: One-piece fit within the allowed orientation, selected orientation, required cut length, and purchase quantity. Existing backing fabric fit Check one usable fabric rectangle against a required backing size and an explicit cutting method. Output: Fit for checked plans, panel cut list, stock length needed, dimensional shortfalls, and remaining full-width length when a plan fits. Compare backing seam layouts Compare vertical and horizontal panel layouts using usable width and seam allowance. Output: Panel counts, seam counts, theoretical yardage by layout, and the lowest-yardage allowed orientation. Quilt binding yardage Calculate binding length and fabric from the finished quilt edge. Output: Binding length, strip count, theoretical yardage, and recommended purchase quantity. Compare backing fabric widths Compare theoretical backing yardage across multiple usable fabric widths. Output: Panel count, seam count, theoretical yardage, and optional recommended purchase quantity for each usable width, plus the lowest-yardage option. Continuous bias binding square Estimate a starting square for continuous bias binding, then check cutting reserve and fabric width. Output: Theoretical area and square side, planned cut square, width fit, theoretical and planned-square yardage, optional purchase quantity. Sashing and cornerstone plan Generate rectangular sashing and cornerstone cuts from block layout dimensions. Output: Sashing and cornerstone counts, cut sizes, strip plans, theoretical yardage and optional purchase quantities. Quilt-top yardage from a cut list Estimate quilt-top yardage from multiple rectangular cut sizes, grouped by fabric. Output: Base cut and strip counts; separate theoretical quantity, cutting reserve, quantity including reserve and recommended purchase by fabric. Finished piece to cut size Add an explicit seam allowance to a finished square or rectangular quilt piece. Output: Cut width and length with total allowance shown for each dimension. Two-at-a-time HST cut plan Plan paired starting squares for half-square triangle units with the standard two-at-a-time sizing method. Output: Starting square size, square pairs to cut, produced HST count, extra units, and unfinished trim size. Quilt border yardage plan Plan straight, butted quilt borders from the center measurements, strip widths, and usable WOF. Output: Per-layer strip cut width and lengths, WOF strips per piece, join counts and finished size after each layer; theoretical and recommended purchase yardage grouped by fabric name. Quarter-square triangle cut plan Choose a named two- or four-fabric QST construction and starting-square size rule. Output: Starting square size, squares per fabric and total, batch yield, extra units, and unfinished trim target. Flying Geese cut and yardage plan Plan method-specific Flying Geese cuts and fabric yardage from custom finished dimensions. Output: Goose and sky cut sizes/counts, WOF pieces per strip and strip counts, unit yield, theoretical yardage and recommended purchase quantity grouped by fabric name. Fat-quarter square yield See how many equal squares fit in one fat quarter before you buy. Output: Number of equal squares that fit in one fat quarter. Fat quarters needed for a square cut list Estimate how many fat quarters cover a required count of equal squares. Output: Fat-quarter count, square yield per piece, and leftover square capacity. Precut pack purchase plan Turn repeated rectangular cuts into required precuts and whole packs to buy. Output: Cuts per precut, theoretical required precuts, recommended whole packs, purchased eligible pieces, unused pieces and extra cut capacity. Batting size Set batting dimensions from quilt top size and a separate batting overhang. Output: Required batting width and length. Batting roll yardage Plan a roll cut from required batting dimensions, with one-piece fit as the default. Output: Fit for the selected construction, panel count and cut length, theoretical roll yardage and separately rounded purchase quantity. Batting package fit Check whether a batting package covers the dimensions your quilt needs. Output: Fit status, usable package orientation, or the remaining shortfall.

Keep the measurements clear.
- 1
Measure the project
Keep mattress, quilt-top and finished-quilt dimensions distinct.
- 2
Use cuttable width
Enter usable fabric width; a bolt label does not establish net width.
- 3
Read each quantity
Theoretical material and recommended purchase remain separate.
