Two identical black Streamline frames, 16×20 inches, each matted to 6×8, hung side by side with even 3-inch gaps — about 36 inches by 21 inches on the wall. Two 6×8 prints, each in a 16×20 field — about 36 inches across.
This is the wide-mat look: a small photograph or print sitting in a generous white border, so the frame carries the wall and the picture stays intimate. Because every frame is the same, the set needs no layout planning — level the row, keep the gaps equal, and the repetition does the work. Sized above a console or dresser.
Hanging note: hang the row with its centre at eye level (about 57 inches from the floor) and check the first frame with a level — the rest follow from it.
