Diagram instantly updates to show the blocks needed as quilt and block size are changed, stashing and bindings are added.

QuiltSize answers the question
How many blocks do I need?

QuiltSize

Get quick answers to basic setting questions

My blocks are made — what width sashing and borders will make the quilt size I want?

How wide should I make my borders so my design comes out at the size I want?

How many blocks do I need if I use 9" blocks instead of the 6" blocks in the pattern?

QuiltSize creates a diagram that shows just how many quilt blocks can fit within a target size.

  1. Enter block dimensions. If the design calls for it, add the width of sashing and borders.

  2. Set the planned size for the quilt —
    mattress
    drops
    pillow tuck

  3. Refine the layout — straight or on-point setting, block-to-block or center panel, single or alternating blocks,.

…and instantly see a diagram showing how the blocks fit within the planned size for the quilt (dotted line).
