Fabric Width Explained: 44″ vs 54″ vs 60″ vs 108″
The width listed for a fabric — 44″, 54″, 60″, or 108″ — is the distance from selvage to selvage across the bolt. It's the single biggest factor in how many yards you need to buy, since a wider fabric covers more area per yard of length.
The common widths, and what they're usually used for
44″–45″: Standard quilting cotton width. This is what most quilting fabric, and a lot of apparel cotton, is printed on. After trimming the selvage edges (the tightly-woven, often printed-text border on each side), the usable width is closer to 40″–42″.
54″: Common for home decor and drapery-weight fabric, and some apparel wovens.
60″: Common for many knits, fleece, and some apparel wovens.
108″–118″: "Wide" or "extra-wide" fabric, most often sold specifically as quilt backing fabric or wide sheer drapery fabric. It exists mainly to let you cover a large area, like a quilt back or a wide window, without piecing multiple widths together.
Why the selvage matters
The selvage is the finished edge on each side of the fabric that keeps it from fraying on the bolt. It's usually not usable in your project, both because it's a different weave density than the rest of the fabric (it can pucker or shrink differently when washed) and because it sometimes has printed manufacturer text or color-swatch dots on it. A reasonable rule of thumb is to plan on losing about 1″–2″ total width to selvage trimming on 44″ fabric.
How width changes your yardage
Because yardage is sold by length, not area, a wider fabric lets you fit more of your project across that length before you need to buy another length's worth. A project that needs 3 pieced panels of 44″ fabric might fit as a single panel of 108″ fabric, which is exactly why quilt backing calculations swing so much between standard and wide fabric — see our queen quilt backing example for the actual numbers.
