A modern classic.
The gold floater frame is 1/4" wide, plus a recessed gap of 1/4" between the outer frame and the canvas, creating the "floater" look.
Dimensions refer to the size of the artwork, so the width of the frame adds 1 inch to the length and width. For example, an 18 x 24 frame fits an 18 x 24 painting, with the outer dimensions of the frame being about 19 x 25 inches.
Please note the depth of the frame as well as the height and width.
