The table starts in A73 and goes down to A84 as i need to have it all
on the same sheet just hidden.

In cell d30 i have the name of a carpet for example Motet Grey
In cell D31 i have the size roll needed for example 4
in cell D32 i want the price of the roll to show up automatically

Perhaps something like this would help:
=VLOOKUP(A30,A74:D84,A31/2,TRUE)
