Feb. 1 has seen the largest congregation of protesters in Cairo's Tahrir Square since protests began in earnest there Jan. 25. However, media reports that 2 million people are congregating in Cairo's largest public square are exaggerated. Based on the size of the square (approximately 490,000 square feet) and the average limit of one person occupying 2.5 square feet in a densely packed crowd, Tahrir Square can accommodate approximately 200,000 people . However, images from Tahrir Square show empty spaces in the middle of the square and along the edges, meaning it is not yet at capacity. Also, protesters are moving around the square. Since movement requires more space, this shows that the crowd density apparently has not reached one person per 2.5 square feet.
