Size & Layout
Standard quilting cotton is ~44" off the bolt, ~42" usable after trimming selvages. Change this if you're working with wider fabric.
Target Quilt Size
🔒 Auto-fit to a target size is part of Quilt Designer Pro.
Fabric Colors
🔒 Choosing your own colors is part of Quilt Designer Pro. Free designs use the default Navy & Cream palette.

Finishing Up
Backing Fabric
🔒 The backing fabric calculator is part of Quilt Designer Pro.
Extra fabric on each edge for quilting/longarm loading — 4" is a common default.
🔒 The piece-by-piece cut list is part of Quilt Designer Pro.
🔓 Free to design and preview. Unlock 24 patterns, custom colors, cut lists, and more for $19.99 — one time, not a subscription.
🔒 AI room previews are part of Quilt Designer Pro (12 free generations included, more available in bundles of 10).
AI Room Preview (photo-realistic, Pro) AI-generated image for inspiration — not a precise reproduction. Colors, exact block shapes, and grid count may not perfectly match your design.
🔒 The setting triangle calculator is part of Quilt Designer Pro.
Setting Triangle Calculator For "on-point" (diagonal) layouts, where blocks are rotated 45°. This is a standalone calculator — it figures out cutting sizes and yardage for the triangles needed to square off the outer edges, but doesn't change the quilt design above.
Not sure how many side triangles you need? A common formula for a straight on-point layout: 2 × (rows + columns of on-point blocks) − 2. Corner triangles are always exactly 4, regardless of layout size.
