Olive Sizes

World olive size grading is calculated by the number of olives per kilo. American size is graded by the number of olives per pound (the number of olives per kilo in the table further below is approximate for American sizes, as the United States Department of Agriculture hasn't set official metric grading.)

You may often see olives designated as 160/180, 400/420, etc. That indicates the range of how many per kilo, in that size. You have to figure out from the context whether the writer is using World measurements or American ones.

The descriptive terms that you will see below were reputedly drawn up in the 1920s by the California advertising firm "Curtis", which drew on names that were being used to promote movies at the time. The terms for larger olives have a good ring of hype around them -- you'd almost think they were describing a circus.

It's a bit odd that the California olive industry continues resolutely to use their own terms and own measurements rather than standardize, especially because this is certainly one field in which the Americans are greatly outnumbered: California produces less than 1/2 of 1 percent of the world's olives, so it would make more sense for them to standardize to the rest of the world.

Size descriptions are listed in order from largest to smallest.
