The larger repeat determines the allowance. Enter 0 for both repeats when the fabric is plain.

Railroad or up-the-bolt?

Railroad (RR)

Fabric is applied across the roll. Confirm that the textile and pattern can be used in this direction.

Up-the-bolt (UTB)

Fabric is applied along the roll. The chart adds a direction allowance; some wider surfaces may require seams.

Confirm direction with your supplier and MG+BW. A pattern name alone does not establish the application.

Application	Usable width	Plain	2–14″	15–24″	25–27″	28–36″
Railroad	54″+	54″: 1.00* Over 54″: confirm	1.10	1.15	1.20	1.25
Railroad	50″	1.10	1.20	1.25	1.30	1.35
Up-the-bolt	54″+	1.30	1.40	1.45	1.50	1.55
Up-the-bolt	50″	1.40	1.50	1.55	1.60	1.65

*The base applies to exactly 54″, railroaded, plain fabric. The original chart prints “0” in the broader plain/RR cell; this tool does not use that as a multiplier. Widths over 54″ for plain RR fabric, widths below 50″ or between 50″ and 54″, and repeats outside the printed bands require confirmation.
