"Up to 3,000 pages" on the box is a laboratory number. It comes from a standard test (ISO/IEC 19752 for mono, 19798 for color) that prints a specific document with about 5% of the page covered in toner, continuously, until the cartridge is empty. Your office prints something else, in a different pattern, so your number will differ. This guide shows how to predict it.
Coverage: the variable that matters most
Coverage is the share of the page that receives toner. Roughly:
- Short business letter, 11-point text, small logo: 4–6%.
- Full page of 10-point text, single spaced: 8–10%.
- Spreadsheet with grid lines and shaded headers: 8–15%.
- Presentation slide with colored background: 30–60%.
- Photo: 60–90%.
Yield scales inversely: at 10% coverage a 3,000-page cartridge prints about 1,500 pages. Color yields are per cartridge, each at 5% of its own color.
Job size
Every print job costs a little extra toner for the drum charge and cleaning cycles, and the first page of a cold printer costs a bit more. An office that prints one-page jobs all day gets fewer pages per cartridge than one printing 20-page reports. The difference is usually 5–10%, not dramatic, but real.
Environment and age
Humidity above about 60% reduces transfer efficiency and the printer compensates with more toner. Cartridges also have a shelf life: HP and Canon recommend using a cartridge within about two years of manufacture and within six months of opening the sealed bag, or toner can clump and yield drops. Rotate stock; do not buy five years of spares because of a sale.
Estimate your own yield
- Note the printer's page count when you install a new cartridge (HP: Reports > Usage Page or Supplies Status; Canon: Check Counter).
- When the cartridge is empty, note it again. Pages printed ÷ rated yield = your coverage factor.
- Apply that factor to the next cartridge's rating, and to the high-yield version if you are considering it.
Two cycles are enough to predict reorder dates to within a couple of weeks.
Examples at typical real-world coverage (about 7%)
- HP 206A black, rated 1,350 pages: expect roughly 950–1,000.
- HP 85A, rated 1,600 pages: expect about 1,100–1,200.
- HP 414A black, rated 2,400 pages: about 1,700.
- Canon 045 black, rated 1,400 pages: about 1,000.
What the "pages" number should change about how you buy
If your coverage factor is high, the high-yield version of your cartridge saves proportionally more money because the fixed costs of a cartridge (shell, chip, drum) are spread over more toner. And a printer with low-yield cartridges (many compact color models) is expensive to run regardless of the cartridge price. Before buying a printer, look up its cartridges' yields and prices with the printer cartridge finder and do the cost-per-page math from our companion guide.

Frequently asked questions
What does 5% page coverage look like?
About a typical business letter: a few paragraphs of 11-point text with a small logo. A page of dense text is closer to 8–10%; a page with a photo or a full-width banner can be 20–50%.
Why did my cartridge print fewer pages than the box says?
Higher coverage than 5%, many short jobs (each job has a small fixed toner cost for warm-up and cleaning), high humidity, or a cartridge that sat unused for a long time. All are normal; the rated yield is a standard test, not a promise.
Do high-yield cartridges have the same coverage rule?
Yes. A 10,000-page X cartridge is rated at the same 5% coverage; at 10% coverage it prints roughly 5,000 pages, still far more per dollar than the standard cartridge.
