Jelly roll quilt planner is the strip-quilt job: you bought (or will buy) a roll of 2.5-inch strips and need a layout that finishes at a named size. Quiltler plans that in the studio with blocks, rails and yardage from pieces — not a generic photo of strip quilts. Pair quick pack math on precut calculator and quilt strip calculator with a saved design here. Sister precut planners: charm pack quilt planner for 5-inch squares and layer cake quilt planner for 10-inch squares.

What jelly roll planning includes
- 2.5-inch strip logic. Rail fences, bargello-style planning, strip-pieced units — widths that match precut rolls, so the throw does not drift into another size.
- Layout, not just arithmetic. Set quilt size, place strip-friendly blocks, add sashing or borders on quilt layout software. The planner is size plus blocks plus fabric, like quilt planner software.
- Fabric roles. Photograph up to ten fabrics on free — one saved quilt — plus solids for scrappy strip mixes. A fuller stash is the subscription.
- Yardage from pieces. Totals count strip segments in the design, not a single rectangle guess. Per-fabric charts and backing are paid. FPP blocks in a strip quilt can still use sheets from foundation paper piecing in the pack.
Calculator first, studio second — or the other way
The precut calculator answers packaging questions: how many strips in a roll, how many rolls for a rough size. The strip calculator handles width-of-fabric strip counts. Those tools are free and need no account. The jelly roll quilt planner is for when you already chose a pattern shape — log cabin rails, hourglass units from strips, a specific block repeat — and need yardage that matches that shape.
Open the studio, set throw or twin inches, and build the strip quilt visually. Save the one quilt you would sew on free, with ten fabric photos. Exact sizes, yardage, and the export for a design you make come with a $4.99 unlock of that layout or Quilter. Public calculator pages stay free. When the design is right, export the printable pack for shop day.
If the plan never names strip width, it is not a jelly roll planner — it is a generic grid with a precut label.
Free planning, honest limits

Who this page is for
Quilters who bought jelly rolls on sale and need a finishable size before cutting. Teachers running strip-quilt classes. Gift makers who want rail fences, not a king by accident. It is a poor fit if you only wanted charm squares — use the charm pack planner — or if you needed no design, only strip count math.
