Batting roll yardage

Plan a roll cut from required batting dimensions, with one-piece fit as the default.

Measurements

Editable example inputs. Adjust them for your project.

Required batting width in Required batting length in

Include your quilter’s required batting overhang in these dimensions. The batting size calculator can help set that target; no overhang is added here.

Usable batting roll width in Batting construction

Default: one unpieced cut. Choose butt joins only when that edge-to-edge method is suitable for your batting and accepted by your quilter. The joined estimate assumes no overlap or width loss. A stitched seam, overlap, join reserve or multiple scraps needs a different plan.

Allowed roll orientation

Vertical panels are cut along batting length; horizontal panels run across batting width. Confirm the permitted orientation for your product. Either compares only these two uniform full-width plans; it does not optimize scraps or mixed layouts.

Purchase rounding yd

Enter the seller’s purchase increment, or leave 0 for an unrounded theoretical quantity. No loft, shrinkage, safety reserve or product availability is inferred.

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

Plan a cut from a batting roll using an entered target rectangle. One unpieced piece is the default; butt joins must be explicitly permitted.

How to use it

Enter required batting width and length, already including overhang.
Measure usable roll width.
Keep one-piece mode unless zero-width-loss butt joins are suitable and allowed.
Restrict or compare roll direction, then enter the seller’s purchase increment if known.

Formula and variables

For vertical orientation, panels span required width and are cut to required length. Horizontal orientation reverses them. In butt-joined mode, panel count = ceiling(required span ÷ usable roll width). Total cut length = panel count × panel cut length; yards = total cut length ÷ 36.

Required dimensionsin: Target batting rectangle with overhang already included.
Roll widthin: Measured usable width across the roll.
Constructionmethod: One piece, or explicitly selected zero-width-loss butt joins.

Independent example

68 × 88 in target and 90 in usable roll width; one piece, width across target width.

90 in covers the 68 in span. One 88 in cut is 88 ÷ 36 = 2.4444 yd. Rounded upward to 1/8 yd gives 2.5 yd.

2.5 yd recommended purchase

What the result means

The joined estimate assumes no overlap or width loss. Confirm that method with the batting maker and quilter; no seam allowance or loft adjustment is inferred.

Common questions

Are butt joins assumed?

No. One piece is the default; select butt joins only when the zero-width-loss method is suitable.

Does the target need overhang added here?

Yes, include the full required target dimensions here; this roll tool adds no overhang.
