使用说明与常见问题How-to & FAQ
「体型计算器」是什么？What is the Body Shape Calculator tool?
根据胸围、腰围、上臀围和臀围，按 FFIT 体型分类法判断沙漏型、梨型（三角形）、倒三角形、矩形、勺型等体型。Find your body shape — hourglass, triangle (pear), inverted triangle, rectangle, spoon and more — from bust, waist, high hip and hip measurements using the FFIT method.
如何使用「体型计算器」？How do I use the Body Shape Calculator tool?
在「体型计算器」中，填写「单位」、「胸围」、「腰围」、「上臀围（腰下约 10 cm）」、「臀围（最宽处）」等参数，结果会随输入实时计算并显示在下方。In the Body Shape Calculator: Fill in "Unit", "Bust", "Waist", "High hip (≈4 in below waist)", "Hips (fullest)"; results are recalculated instantly as you type.
判断依据是什么？What is it based on?
采用服装学中的 FFIT（Female Figure Identification Technique）规则，按英寸差值判断，例如沙漏型：胸 − 臀 ≤ 1 英寸且臀 − 胸 < 3.6 英寸（即臀部最多可比胸部大约 3.6 英寸），并且胸 − 腰 ≥ 9 或臀 − 腰 ≥ 10 英寸；臀部比胸部大 3.6 英寸以上时归入下沙漏型、勺型或梨型。体型分类只是穿衣参考，没有好坏之分。It uses the FFIT (Female Figure Identification Technique) rules from apparel research, based on differences in inches — e.g. hourglass: bust − hips ≤ 1 in and hips − bust < 3.6 in (so hips may be up to about 3.6 in larger than the bust), with bust − waist ≥ 9 or hips − waist ≥ 10 in; hips 3.6 in or more larger than the bust fall under bottom hourglass, spoon or triangle. Shapes are a styling guide only; none is better than another.
