Kalkulator Diagonal 🔸
Calculate side and corner setting triangle sizes for on-point quilt layouts. Get exact cut square sizes and triangle counts for your diagonal quilt setting.
How to Use the On-Point Calculator
Enter the finished block size and grid dimensions (blocks across × blocks down). The calculator gives cut square sizes for both setting triangle types plus how many squares to cut.
Side setting triangles are X-cut (diagonally twice) to place the straight grain on the outer quilt edge. Corner setting triangles are cut once diagonally. Always cut setting triangle squares with the straight grain in mind.
Approximate finished dimensions are calculated before borders. Cut a few extra setting triangles as insurance — they use little fabric and prevent delays from cutting errors. Square up the quilt before adding borders.
Pertanyaan yang Sering Diajukan
What is an on-point quilt setting?
An on-point setting rotates blocks 45° so they appear as diamonds. Setting triangles fill the gaps at the edges and corners, creating a diagonal layout that adds visual movement.
How do I calculate setting triangle sizes?
Side triangles: cut square at (block × 1.414 + 1.25"), X-cut → 4 per square. Corner triangles: cut square at (block ÷ 1.414 + 0.875"), single diagonal cut → 2 per square.
Why do setting triangles use an X-cut vs a single diagonal cut?
Side triangles are X-cut to keep the straight grain on the outer quilt edges, preventing stretching. Corner triangles are cut once on the diagonal for the same reason — straight grain on outer edges.
