Translation: When its length and width are specified.
Two dimensions matter independently: tul (length) and ard (width). Two pieces of identical length can differ substantially in usable surface area and price if their widths differ.
For example, specifying “each roll is 25 metres long and 1.5 metres wide” removes an important uncertainty. A recognized, reproducible measuring unit is necessary; an unidentified private measuring stick would recreate the very uncertainty salam is meant to prevent.
