边框计算器 🔲
计算拼布边框的用布量和布条数。输入拼布尺寸和最多5种边框宽度，获取每道边框的精确用布量。
How to Use the Border Calculator
Enter your finished quilt dimensions (before adding borders), select 1–5 borders, then enter each border's finished width. The calculator uses 40" usable fabric width by default — update this if your fabric is wider.
The calculator adds 0.5" to each finished border width for seam allowances and calculates total linear inches needed per border. Strips are assumed to be cut cross-grain (across the width of fabric).
Each border's yardage is shown separately since borders are often different fabrics. The total at the bottom combines all borders — useful when planning a same-fabric or scrappy border set.
常见问题
如何计算被子边框的码数？
量出所需全部边框条的总长，加上缝份，再除以可用布幅。我们的计算器会自动处理。
斜接角和对接角有什么区别？
对接角在边框相遇处直接缝合。斜接角以45度裁剪，形成相框般的效果。斜接角用布略多。
我的被子边框应该多宽？
一个常见准则是让边框宽度与块尺寸成比例——大约为块尺寸的1/4到1/3。宽度不一的多重边框能形成富有动感的框边。
