It came in tact and in good time
Jar size guide
Mason jars come in two common mouth sizes and a handful of standard volumes. Use the charts below to match jars to lids, or measure the jar you already have.
Mouth sizes
The mouth size decides which lids, bands and straw lids fit your jar.
70 mm
About 2 3/4 in across the lid. The most common size for jelly jars, pints and quarts.
Shop regular mouth →86 mm
About 3 3/8 in across the lid. Easier to fill, scoop from and clean.
Shop wide mouth →Gem
Gem jars use their own lid size, so regular and wide mouth lids won't fit them.
Shop Gem jars & lids →Measure
Measure straight across the top of the lid, or across the outside of the threads with the lid off. Close to 70 mm is regular, close to 86 mm is wide.
Commercial vs vintage sizes →Volumes

Measurements are nominal. American jars are usually labelled in ounces and Canadian jars in millilitres, so a 16 oz pint and a 500 ml jar are close but not identical. Vintage jars can vary, so check each listing for its measured volume.
