Definition: The smaller sizes of paper generally used by quick printers as well as desktop printers are called cut sizes. Two common cut sizes are 8.5x11 (letter size) or A4 and 11x17 (tabloid) or A3.
Most laser printers, photocopy machines, fax machines, and small presses are designed for the letter size sheets or cut sizes no larger than the 11x17 or A3 sizes. These common cut sizes are often sold by the ream in office supply stores.
The cut size is not the same as the trim size, unless the project requires no trimming and the project is printed on cut size paper.
