Please consider the following examples:
The size/sizes of the planets is/are written here. The door/doors of a 100 houses is/are 100Kg. Men's nose/noses is/are bigger than that/those of women.
Which ones are correct? Is there a rule? In every example the attribute is singular. Every planet has only one size. Every house has only 1 door. Needless to say, every man or woman has 1 nose.
I encourage you to google the phrase, "sizes of planets." You will find both usages, "size" and "sizes".
