Most tape drives could support a maximum reel size of 10.5 inches (267 mm). A so-called mini-reel was common for smaller data sets, such as for software distribution. These were 7-inch (18 cm) reels, often with no fixed length—the tape was sized to fit the amount of data recorded on it as a cost-saving measure. [citation needed]
This allows projectionists running reel-to-reel to change over to the next reel on the other projector. A so-called "two-reeler" would have run about 15–24 minutes since the actual short film shipped to a movie theater for exhibition may have had slightly less (but rarely more) than 1,000 ft (305 m) on it.

The first commonly available increase in tape length resulted from a reduction in backing thickness from 1.5 to 1.0 mil (38 to 25 μm) resulting in a total thickness reduction from 42 to 35 μm (1.7 to 1.4 mils), which allowed 3,600 ft (1,100 m), 1,800 ft (550 m), and 900 ft (270 m) tapes to fit on ten-and-a-half-, seven-, and five-inch reels respectively.
It could play stereo quarter-track tapes but record only in one quarter-track mono. Home equipment with missing features were fairly common in the 1950s and 1960s. For home use, simpler reel-to-reel recorders were available, and a number of track formats and tape speeds were standardized to permit interoperability and prerecorded music.

Continuous form paper is used in some of the fastest types of printing systems, some of which print text at a rate of 20,000 lpm (lines per minute). This will produce about 400 pages per minute, using about 8–11 large boxes of paper for every hour of printing (affected by character density, and other details such as paper weight).
The alternative Super series, denoted SnR, nR Plus or nR+, has an aspect ratio of 3∶2 (or as close as possible) and thus provides a better fit for standard 135 film (35 mm) at sizes of 8 inches or above. 5R is twice the size of a 2R print, 6R twice the size of a 4R print and S8R twice the size of 6R. 4D/6D is a newer size for most consumer ...
