How many years did it take to make the Qu'ran?

The Qur'an was sent down by Allah to the lowest heaven all in one night, this is known as Laylatul Qadr and this a day towards the end of the month of Ramadhaan.

It was then revealed to Muhammad bit by bit addressing the circumstances of his life and struggle and that of his companions over a period of 22 years, 5 months and 14 days.

Starting at the age of 40, which was 13 years before he emigrated and until 10 years after the emigration.
