Key Features

Enter Binding Length and Get the Square Size

Choose your binding type, finished width, and safety margin. The calculator outputs the square size to cut, cut-strip width, total yield, and safety extra.

  • Length unit (in/cm/m/yd)
  • Width unit (in/cm)
  • Fat-quarter fit indicator
Primary mode showing required square size and yield

Project Mode for Quilts and Garments

Calculate binding from rectangular quilts, square quilts, circles, necklines, or multiple armholes—then immediately see the required square size.

  • Quilt presets
  • Joining allowance included
  • Instant recalculation
Project dimensions mode showing quilt inputs and results

Visual Diagram + Printable Instructions

The diagram walks through the 4 steps (square → marked lines → tube → spiral cut). Print or save as PDF for a single-page reference.

Common Questions

Many calculators ignore waste inherent to the tube method (triangular ends and handling loss). This tool includes a safety margin so you can plan for real-world cutting and seaming.
Finished width is what you see on the quilt/garment after folding and stitching. Cut width is the strip width you cut before folding. The tool computes cut width from your finished width and binding type.
