🔒 The setting triangle calculator is part of Quilt Designer Pro.
Setting Triangle Calculator
For "on-point" (diagonal) layouts, where blocks are rotated 45°. This is a standalone calculator — it figures out cutting sizes and yardage for the triangles needed to square off the outer edges, but doesn't change the quilt design above.

Side triangles needed
Not sure how many side triangles you need? A common formula for a straight on-point layout: 2 × (rows + columns of on-point blocks) − 2. Corner triangles are always exactly 4, regardless of layout size.
