Short answer: A wallpaper roll is the standard unit in which wallpaper is made and sold: a long strip wound on a core and hung in vertical lengths. Roll width, length and area differ between the American and European systems, so a roll is always described by its dimensions and by whether it is a single or double roll.

Where sources differ
Roll sizes are not universal. The Wikipedia page gives the American roll as 27 in by 27 ft, while the trade glossary gives a range for the American single roll and different Euro-roll examples (21 in by 16 ft, 27 in by 13 ft) from Wikipedia's 52 cm by 10 m European roll. Always state dimensions in numbers.
