# what does the “a cap of” mean in following paragraph?

I recently received a letter from a journal, the following words are confusing with me, I　do not know exact meaning of a cap of.

Please also be aware of TCYB page length policy with a cap of 12 pages plus two additional pages with a charge of \$175/page, for a regular paper, provided that you promise to pay the bill after the publication.

• "cap" is used here in the sense of "limit": an upper limit (as on expenditures): ceiling – apsillers Feb 6 '15 at 17:06

• This just makes me realize why papers I've read on IEEE are never longer than 14 pages. – Damkerng T. Feb 6 '15 at 17:26
