How long does it take for grass to grow 3 inches?

Most established grass grows at a rate of 2-6 inches per month, depending on the variety, so grass grown from seed will likely take at least a month to reach 3 inches in height since there is plenty of energy going towards the vegetative and elongation stages of its growth cycle.

Is it true the shorter you cut your grass the faster it grows?

Grass grows faster after it's been cut short as it tries to rebuild itself to its genetic norm. A good in-season height for most turfgrasses is 2½ to 3 inches — typically the highest setting on mowers.
