what size is a normal piece of paper

A “normal” piece of printer paper is usually one of two standards, depending on where you live:

• In most of the world: A4 size , which is 210 × 297 mm (about 8.27 × 11.69 inches).

• In the United States and a few other places: US Letter size , which is 8.5 × 11 inches (about 215.9 × 279.4 mm).

So if you’re asking “what size is a normal piece of paper,” it’s typically A4 or US Letter, with A4 being slightly narrower and a bit longer than Letter.
