There is no fixed duration: the cap gap lasts exactly as long as needed to bridge the gap between the end of your F-1 status (or OPT work authorization) and the start of your H-1B. Because that starting point differs from person to person, the length of the extension varies case by case.
The logic is straightforward. H-1B status only takes effect at the start of the next fiscal year, but many F-1 holders would see their status expire before that date. The cap gap fills precisely that interval, running from the date your F-1 status would have ended until the moment your H-1B becomes effective at the beginning of the fiscal year.
This bridge only applies if the H-1B petition was filed while your F-1 was in good standing and the change-of-status request is still pending. Because this is a mechanism sensitive to dates and rules that may change, confirm the period that applies to your situation through the official source, USCIS, or with a qualified immigration professional before making any commitments.
