A detailed comparison to help you choose the right option for your next quilting project
Fat quarters give you maximum cutting flexibility for any block pattern, while jelly rolls are purpose-built for efficient strip quilts. Choose fat quarters when your pattern has varied piece shapes; choose jelly rolls when you want speed and coordinated strips.

|---|---|---|
| Dimensions | 18" x 21" | 2.5" x 42" |
| Typical Count | 1 piece | ~40 strips |
| Price Range | $3-$6 each | $30-$45 |
| Equivalent Yardage | 0.25 yards (cut differently) | ~2.75 yards |
| Best For | Any quilt pattern, small projects, applique, and building a coordinated fabric stash | Strip quilts, bargello patterns, jelly roll races, and binding strips |
Fat quarters (18" x 21") are a single rectangular piece offering width and height for diverse cuts. Jelly rolls are 40 long, narrow strips (2.5" x 42") designed for strip-based techniques. Fat quarters give you a 2D cutting surface; jelly rolls give you linear yardage.
Fat quarters work with virtually any quilt pattern — from traditional blocks to applique to modern designs. Jelly rolls specialize in strip quilts, bargello, log cabin variations, and jelly roll races. If your pattern calls for squares, triangles, or mixed shapes, fat quarters win. If it calls for uniform strips, jelly rolls are faster.
A jelly roll race quilt can be finished in an afternoon with just straight sewing — no complex cutting required.
Blocks like Ohio Star or Bear Paw need squares, triangles, and rectangles that require the cutting flexibility only fat quarters provide.
The versatile size means fat quarters can be used for almost anything later, while jelly roll strips are limited to strip-based projects.
Pre-cut strips eliminate cutting time entirely and strip-based patterns assemble quickly.
A fat quarter bundle of 20 prints typically costs $50-$90. A jelly roll of 40 strips costs $30-$45 and covers more of a collection. Per fabric variety, jelly rolls are more economical. Per usable fabric area, fat quarters offer more cutting options.
