The chart below is not every size a manufacturer will make. It is every size enough people search for that it is worth having a page about, which is a more useful list — a size nobody asks about is a size you will wait weeks for.
Read the rough opening column carefully, because it is the one that costs money when it is wrong. For a sectional door the rough opening equals the door size exactly: a 16x7 door needs a 16'0" by 7'0" finished opening, not a generous one. Framing wider does not give you room, it gives you a gap the weather seal cannot close.
The width and height in the chart are the DOOR, and the door is the opening. Neither of them is the concrete apron, the driveway, or the distance between the two nearest studs. Measuring the wrong one of those is the single most common reason a door arrives and does not fit.
