Assuming we are talking about land surface (not water), the earth has about 148,940,000 square kilometers. So, it could "hold" slightly less than 149 trillion people, if they each had their own square meter of ground. (148,940,000 km2 = 148,940,000,000,000 m2.)
However, some estimate only about 18.5 million km2 are inhabitable by humans because high mountains, deserts, ice, etc. cover the rest. So, only about 18.5 trillion people would "fit", assuming one square meter (m2) per person.
Now, if we give everyone a little more room (say 1/2 acre to grow food), then that would allow for about 9 billion people. (1 acre = about 4,047 square meters. 1/2 acre = 21,780 ft2 or a square plot of about 147 ft on the sides.)
Earth's population just surpassed 7 billion in 2011. It is estimated we will reach 9 billion by 2046. Some would argue the earth is just about full.
And sustainability is another issue.

How many humans does it take to fill up earth's land area?
On my calculations the total foot area i use when both stand together is 0.0636 square meters. Almost 15 people can stay shoulder to shoulder inside every square meter. 1 square meter is the same as 0.000 001 square kilometers. Inside one square kilometer we can place 15 million people. Earth is 148,940,000 km2 * 15000000 give the number 2341000000000000 Means that 2341000000000000 / 7 000 000 000 (human population) Says that to fill the earth the currently world population needed to be multiplied by 334428 times. For fill up the entire earth we just take the total surface area. 510,072,000 km2 * 15000000 = 7651080000000000.

How may smarties would it take to fill up earth?
To estimate how many Smarties it would take to fill the Earth, we first need to calculate the volume of the Earth, which is approximately 1 trillion cubic kilometers (or 1 x 10^12 km³). A single Smartie has a volume of about 0.5 cubic centimeters (or 0.0000005 km³). Dividing the Earth's volume by the volume of a Smartie gives an approximate total of around 2 x 10^21 Smarties needed to fill the Earth, assuming no gaps and complete packing.
