"oz." question

feldhouse's picture

Hey everyone,

I am designing a menu and don't have my type bible in front of me. Since I just moved I am sure it's packed away in a box that will take a few days to uncover. I can't remember off hand the proper way to spell out the ounce abbreviation. I know AM and PM are small caps, but would oz. be?

Any clarification on this is greatly appreciated!

No, since it's not an acronym. Opinions might differ on the period, but I'd say that since it's a spliced abbreviation (from Italian "onza"), no period is necessary. Then again, I don't put a period after Mr or Mrs either.

i would say do what looks right. rules like that are impossible to follow in all usages.

if it reads with absolute clarity and stylistic integrity, it's right.

I would say lowercase, not smallcaps, and definitely with a period after it: oz.

I recommend Fowler's rule that abbreviations should always have a period unless they end in the same letter with which the full word ends. Ergo:

12 onza -> 12 oz.


Saint John -> St John
