Sorry... Couldn't get pictures to attach to the original. Here they are

What I see in your photo is an off side fireplace. You have one (too large) mock up with the fireplace...okay, that's fine, but why another one, just hanging out there in space.

To size a chandelier for your living room, you add the length and width of the room and convert to inches. Example. 20' x 18' = 38'. converted to 38" wide.

You need to make a floor plan before you decided on the lighting.

@judianna20  I am only doing one in front of the fireplace, not both.  I am just trying to decide on bigger or smaller.

Michelle- I know this is an old post, and it appears you didn’t get any help. Do you mind sharing what size you decided? I’m in the same boat and my measurements and space is very similar! Thank you!
