📦 纸箱尺寸与快递体积重计算Carton Size & Volumetric Weight Calculator
输入纸箱内径和纸板类型（三层/五层/七层，B/C/E 楞），估算外径、制造尺寸、内外容积和单个用纸面积；同时按 5000/6000/8000/12000 抛比计算快递体积重和计费重量，并附邮政 1–12 号纸箱常见规格表。Enter inner dimensions and board type (3/5/7-ply, B/C/E flute) to estimate outer and manufacturing sizes, volumes and board area per box, plus volumetric and chargeable weight at 5000/6000/8000/12000 divisors, with a table of common Chinese postal carton sizes 1–12.
常见邮政纸箱规格（1–12 号，各地各厂略有差异）Common Chinese postal carton sizes (No. 1–12; vary slightly by maker)
外径按“内径 + 2 × 纸板厚度”（高度 + 4 × 厚度，含上下摇盖）近似估算，制造尺寸约为内径 + 1 个厚度；用纸面积按普通开槽箱（0201 型，接舌 30 mm）估算。实际尺寸与压线工艺有关，下单前请与纸箱厂确认。体积重 = 长 × 宽 × 高（厘米）÷ 抛比，计费重量取实重与体积重中较大者，具体以快递公司规则为准。Outer size is estimated as inner + 2 × board thickness (height + 4 ×, for the top and bottom flaps); manufacturing size ≈ inner + 1 thickness; board area assumes a regular slotted carton (FEFCO 0201, 30 mm glue tab). Real sizes depend on the scoring — confirm with your carton maker. Volumetric weight = L × W × H (cm) ÷ divisor; carriers bill the larger of actual and volumetric weight — check your carrier’s rules.

「纸箱尺寸与快递体积重计算」是什么？What is the Carton Size & Volumetric Weight Calculator?
输入纸箱内径和纸板类型（三层/五层/七层，B/C/E 楞），估算外径、制造尺寸、内外容积和单个用纸面积；同时按 5000/6000/8000/12000 抛比计算快递体积重和计费重量，并附邮政 1–12 号纸箱常见规格表。Enter inner dimensions and board type (3/5/7-ply, B/C/E flute) to estimate outer and manufacturing sizes, volumes and board area per box, plus volumetric and chargeable weight at 5000/6000/8000/12000 divisors, with a table of common Chinese postal carton sizes 1–12.
如何使用「纸箱尺寸与快递体积重计算」？How do I use the Carton Size & Volumetric Weight Calculator?
填写商品需要的内径长宽高和纸板类型，下面的卡片显示外径和体积重；填入实际重量后会告诉你按实重还是体积重计费。点规格表的“填入”可以快速比较标准纸箱。Enter the inner L×W×H and board type; cards show the outer size and volumetric weight. Add the actual weight to see which one is billed. “Use” in the table loads a standard carton.
体积重怎么算？How is volumetric weight calculated?
长 × 宽 × 高（厘米）÷ 抛比。国内快递常用 6000，国际快递和空运常用 5000；计费取实重和体积重中较大者。L × W × H in cm ÷ divisor — 6000 is common for Chinese domestic couriers and 5000 for international air; you pay for the larger of the two weights.
外径为什么只是估算？Why is the outer size an estimate?
实际外径和压线位置、纸板克重有关，不同纸箱厂略有差别，批量定制前请让厂家确认。It depends on scoring and board grade, which vary between makers — confirm before ordering in bulk.
