Granny Square Designer

Plan granny square projects in minutes—mix colors, design bags, blankets and custom projects, and let the app calculate yarn automatically.

Give classic granny squares a fresh, modern look. Plan bags, blankets, and custom projects with clarity. Pick a square from one of our categories—classic, solid, flower, mitered, circle, other, or seasonal—assign colors to each round, and mix, match, and combine square designs. Review a clean summary with a preview image and square size, the number of squares you’ll need for your project, yarn usage estimates based on your hook size, a diagram, and written instructions in your preferred terminology (SK, CZ, UK, US, DE, FR, ES, IT, PL, HU). Metric or imperial units supported. Start free with one Classic square to try the app’s full functionality; you can upgrade anytime for the full library and unlimited projects. Privacy-friendly: we store only your email and language/terminology/measuring-system preferences to run the app. No additional personal data required. For users 13+. Operated by LT Studio s.r.o.
