A Complete Guide to Glass Jar Sizes and Capacities

Getting the jar size right matters for cost, shipping and shelf presence. This guide breaks down common glass jar capacities and how ml relates to product weight.

ml vs grams

Millilitres measure volume; grams measure weight. Honey is denser than water, so a 400ml jar holds roughly 500g of honey. Always match the jar’s ml to your product’s density.

Common sizes and uses

• 41–125ml — samples, favours, spice testers
• 200–360ml — retail honey, jam, spreads
• 500–750ml — family packs, pickles
• 1000ml+ — bulk, food service

Don’t forget dimensions

Height and width affect carton packing and shipping cost. Slim, stackable shapes lower freight. Every product page on our site lists exact dimensions and MOQ.
