斜角排列计算器 🔸
计算斜置拼布布局的侧边和角部设置三角形尺寸。获取精确的裁剪正方形大小和三角形数量，用于您的对角线拼布设计。
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.
常见问题
拼布中的「斜置」是什么意思？
将块「斜置」是指把它们旋转45度使其呈对角摆放。这会形成块仿佛漂浮的动感设计，并需要定位三角来填充边缘。
如何计算定位三角的尺寸？
对边侧定位三角，把成品块尺寸乘以1.414再加1.25英寸。对角三角，把块尺寸除以1.414再加0.875英寸。我们的计算器会自动完成。
为什么斜置被子需要角三角？
当块斜置时，角三角填补被子顶层的四个角。没有它们，角就会残缺，被子也不会有笔直的边缘。
