Lipid rafts form because membrane component such as sphingolipids and cholesterol molecules preferentially associate with another. Why do you think that the aggregates are limited in size?
Although we tend to think of the cell membrane as a smooth covering for a cell, the membrane can undergo dramatic shape changes as the cell contents (the cytosol) oozes around underneath the membrane. As a result, the cell membrane can curve abruptly to allow a projection or an indentation in the cell surface (see photo). Cells facilitate the curving of the membrane by swapping out the acyl chains of membrane phospholipids. Which would have a greater effect on the ability of the membrane to curve: replacing saturated acyl chains with unsaturated acyl chains or replacing unsaturated acyl chains with saturated acyl chains?
