⚠️ Heads up: The number of squares needed () is not a
whole number. Your quilt dimensions may not divide evenly by this square size — you may need to adjust your
finished size, square size, or plan for partial squares or a border to make up the difference.
How we got there
Width × height (total area)
Area ÷ (square size × 2)
Rounded to whole squares
Tip: If this number doesn't divide evenly, consider adding a border strip or adjusting your quilt dimensions
slightly so the squares fit perfectly without partial pieces.
