卫生纸真正决定用量的是克重而非层数，单卷克重≥120g/卷（有芯）或≥100g/卷（无芯）才算厚实耐用，纯克重同价下比层数更值得关注

Unverified看克重而非层数判断实惠度：卫生纸的实际用量由每卷克重决定，3层薄纸可能比2层厚纸更不耐用，选购时用总克重÷卷数换算单卷克重，单卷≥130g才算扎实90% similarUnverified卫生纸的定量（克重）比层数更能反映真实厚度，同为3层但定量差异可达20g/㎡以上，选购时优先看单张克重≥13g/㎡才算扎实，而非只看层数标称89% similarUnverified纸手帕定量（克重）比层数更能反映实际厚度，同为3层，克重≥13.5g/m²的纸巾湿强度和吸水性明显优于低克重款80% similarUnverified会员店厨房纸巾看'层数×单张克重'而非只看抽数，双层且克重≥40g/㎡才有真正吸油吸水力，单层薄款抽数虚高性价比反而低76% similarUnverified克重是平替品质核心：单片下水克重（含液量）达40g以上、无纺布基布克重≥45g/㎡才算扎实，低价平替常压到30g以下，表现为薄、易破、擦两下就干75% similar
