容量越大杯口越宽，量取少量液体时液面浅、刻度间距密，读数精度反而下降；大容量与小份精度不可兼得

Unverified量杯规格越大精度越低：同一500ml杯上10ml刻度误差可达±5ml，量20ml以下小容量应改用量勺或50ml小量杯，别用大杯量小量81% similarUnverified量小份精确计量（如10ml以内调味/发酵剂）用带mg刻度的小容量量杯误差更小，用500ml以上大杯量少量液体读数误差可达±20%76% similarUnverified容量建议选240ml以上宽口款，折叠奶瓶因瓶身软、刻度观察不精准，小容量（150ml以下）在实际冲调时刻度误差影响更明显75% similarUnverified容量越大瓶身越重，定量按压时越难稳定单手操作；建议单瓶容量控制在150-300ml，大容量反而影响定量准确性74% similarUnverified瓶口内径与扩散范围成正比：窄口瓶（≤1.5cm）挥发慢更省液但扩香弱，宽口瓶扩香强但液体消耗快，大空间选宽口小空间选窄口72% similar
