Could but don't have to. Is the area more symmetrical? Photo would help?

What lamps where are they going honestly how would we know with so little info. Post pics of the room the lamps and then see.

Hello Diane,

I would recommend different lamps that compliment one another. Matching lamps are great on a diningroom buffet or in a very formal space where symmetry is required.

Best of luck....

They needn't match, but they should complement each other. For example, the same type of shade and probably the material. In my 16 X 20 ft living room I have three teak floor and two table lamps, all with the same linen-type shade. In addition I have two floor reading lamps that are white to match the woodwork.

From my comments you might infer that two lamps might not be enough.
