These were known as long-play tapes. [1] Manufacturers also referred to 3 + 3 ⁄ 4 inches per second (9.525 cm/s) tape speed as long-play. A further reduction of backing to 0.5 or 0.75 mils (13 or 19 μm) and total thickness to 26 micrometres (1.0 mil) resulted in double-play tapes of 2,400 feet (730 m) on a seven-inch reel. [1]

To convert inches to hands, the number in inches is divided by four, then the remainder is added after the radix point. Thus, a horse that measures 60 inches is 15 hands high (15 × 4 = 60) and a horse halfway between 15 and 16 hands is 15.2 hands, or 62 inches tall (15 × 4 + 2 = 62) [ 5 ] [ 7 ] Because the subdivision of a hand is a base 4 ...
The typical range lies between 1 ⁄ 2 to 2 ⁄ 3 inch (12.7 to 16.9 mm) for the UK/US size system and 4 ⁄ 3 to 5 ⁄ 3 cm (13.3 to 16.7 mm) for the European size system, but may extend to 1 ⁄ 4 to 3 ⁄ 4 inch (6.4 to 19.1 mm) and 2 ⁄ 3 to 6 ⁄ 3 cm (6.7 to 20.0 mm).
A foot-long sheet with the common width of Letter and (Government) Legal, i.e. 81⁄2 in × 12 in (215 mm × 305 mm), would have an aspect ratio very close to the square root of two as used by international paper sizes and would actually almost exactly match ISO RA4 (215 mm × 305 mm).
