1994 Honda Accord LX(4 Door) Rotor Size?

[Mike]

I went to Auto Zone the other day and purchased rotors for my 94'honda LX....When I let him know that I needed rotors he ask me what size because there were two different sizes i didn't know the size so i had to buy both sizes the only way to find out he said was to take the old rotors off....Does anyone know the right size rotors for a 1994 Honda Accord LX? so i cant take the other size back and get my money back!
