Bien Dit! - P. 210 Grammaire II <<The comparative with adjectives and nouns>>

With the comparative, there is no adjective agreement in number and gender when (MUST AGREE EVERY OTHER TIME)…

«C’est» is used before the expression.

To compare nouns, use these expressions:

• plus + adjective + que (more… than)

• aussi + adjective + que (as… as)

• moins +adjective + que (less… than)

You can also compare nouns using plus de, moins de, and autant de (as much as) before the noun. Remember to use que/qu’ to continue the comparison.

Il y a plus de vaches que de canards.

Elle a moins de chevaux que ses grands-parents.

Bien!
