Measure first · Plan second

Your squares.
A blanket-sized plan.

Estimate yarn from the squares you have actually made. Build a rectangular grid, add your own joining and border allowance, then send the length to your shopping list.

Use a representative sample

For identical squares made from one yarn and colour. Multi-colour squares need a separate measured amount for each colour; do not enter their combined weight here.

Enter a separately estimated finishing length for the same yarn and colour. Zero excludes it; the tool cannot infer it from blanket size. Sample weights must use a consistent treatment of tails.

An estimate from your sample

Your grid & yarn

Example inputs are ready to try. Replace them with your own measurements before planning a purchase.

A worked example you can check

Three identical squares weigh 24g together, so one weighs 8g. A label stating 200m per 100g gives 16m per square. A grid of 6 × 8 squares contains 48 squares and needs an estimated 768m for the squares. If you enter another 60m for joins and a border in the same yarn, the total is 828m.

At 12cm per square, the unjoined grid is 72 × 96cm. That is not a promised finished blanket size: joining, borders, blocking and tension can change the result.

What to measure before trusting the estimate

  1. Make representative squares with the intended yarn, hook and stitch instructions.
  2. Weigh several together where practical, without labels or packaging. Keep the treatment of tails consistent.
  3. Record their size in the condition your pattern specifies.
  4. Estimate joining and border yarn separately. If those use a different colour, add a separate row in the shopping planner.

The transfer rounds the estimate up to the nearest 0.001m so it does not lose a small required length. It adds no automatic percentage. You can choose an allowance and subtract stash in the shopping planner.
