There are a lot of types of dinosaurs, so it depends what kind of dinosaur you are talking about.
The tallest known dinosaurs were a lot taller than the tallest giraffes.
Adult giraffes can reach a height of about 5-6 meters depending on the individual. The largest and tallest dinosaurs are found in the 'long neck' group the Sauropoda. Unfortunately the dinosaurs thought to be the tallest are very incomplete so there is uncertainly as to their exact dimensions. There is also uncertanty as to how much range of motion the tallest dinosaurs had in their necks, which effects how tall they would be.
The dinosaur Giraffatitan is probably the most complete tall dinosaur. It might have been able to reach about 14m in height (This is dependant on how much range of motion there was in its neck).
Sauroposeidon is another contender but is only known from fragmentry remains. It is estimated that it might have been able to reach 17m in height.
Answer
They would be about the same height. T-rex averaged about 15-20 feet tall and Giraffes average about 19 feet tall.
Answer
to my opinion a tyrannosaurus Rex is taller because an AVERAGE tyrannosaurus Rex size is around 20 ft. tall and the TALLEST a giraffe grows to is about 19 ft. tall so there's your answer tyrannosaurus Rex was taller.
An elephant is bigger in its weight,in its size,not in length,so giraffe is taller then elephant.
The giraffe is probably taller considering they can reach tree tops.
