Subject: Which is stronger? Air or gravitational force?

We were having a *silly* experiment and something funny happen. May I know how come a smaller and lighter piece of paper drops to the ground faster than a bigger piece? (All the variables that we are supposed to keep the same,we did) We tried it again and again and the smaller paper still dropped to the ground faster than the bigger one! All right, is it because the bigger paper have more exposed surface area and hence more air stops it from falling to the ground?
