Measure a motif after blocking and joining
Use the distance between corresponding points of joined motifs. An 11.5 cm loose square with a join adding 0.5 cm per repeat has a 12 cm pitch in this example.

Use the distance between corresponding points of joined motifs. An 11.5 cm loose square with a join adding 0.5 cm per repeat has a 12 cm pitch in this example.
Work through the example
- Finish several motifs as the project will be finished. Join at least a small row and column with the intended method.
- Measure between repeated landmarks across several intervals and divide by the number of intervals, not the number of landmarks. Three intervals spanning 36 cm give 12 cm.
- Record horizontal and vertical pitch separately. Enter 12 × 12 cm only if both axes actually agree; then plan the 120 × 180 cm motif field.
Check before committing
The 0.5 cm join contribution is an example, not a standard seam allowance. Some joins overlap edges or behave differently under load.
Method and sources
These are original planning examples using the linked tools’ methods. Replace measured inputs with your own samples; a calculator cannot validate the construction. Keep the resulting measurements, choices and remaining checks with the project.
Motif layout planner
Turn a measured, joined motif repeat into rows, columns, and a make count for a rectangular project.
Before you use this tool
Join and finish several sample motifs before measuring the repeat pitch between matching points. Enter the motif field after subtracting borders.
Cover rounds up each axis; complete-only rounds down. Extra motifs are spares outside the layout.
Extra outer-edge allowance is added twice to each target dimension. Internal joins belong in the measured motif pitch.
Method and limits
Formula and assumptions
Required field = target width/height + twice the outer-edge allowance. Divide each axis by the finished joined motif pitch, swapping axes when rotated. Cover rounds up; complete-only rounds down. Multiply rows by columns, then add the rounded-up spare percentage. This model covers aligned rectangular layouts.
Worked example
Example: a 10 × 10 cm joined repeat covering 95 × 135 cm needs 10 columns × 14 rows = 140 motifs; 5% allowance means making 147.
Limits and rounding
Results are planning estimates from the values entered. Displayed decimals are rounded for craft use; whole materials and repeats round up where the method says so. Confirm gauge, material behavior, construction, and finished measurements before committing supplies.
