The making toolkit
Numbers that help you make.
Start with your own measurements. Explore a layout, check the maths and keep the method beside the result.
Blanket planner
Choose a size, arrange your colours and see how many squares you need.
02 / Yarn & materialsYarn calculator
Estimate yarn and whole balls from a swatch you have actually made.
03 / Gauge & sizingStitch calculator
Turn a washed swatch into stitch and row counts for your next rectangle.
04 / Quick referenceCrochet converter
Check common hook sizes, US/UK stitch terms and length conversions.
Choose the right starting point
For a blanket made from square motifs, start with the visual planner. For a continuous rectangular fabric, measure a swatch and use the stitch calculator for dimensions and the yarn calculator for materials. The converter helps you align units and pattern language before either calculation.
All tools work in your browser without an account. Results are estimates where they depend on physical materials. Each page explains the assumptions, shows a worked example and links to a more detailed field note. Use the print option on calculation pages to keep the input values with the result.
