0.75in X 0.75in on fabric.
This repeat is 4.50in x 4.50 inches on fabric and 4in x 4in on wallpaper. There are 4 sizes of this design. IMPORTANT: I recommend, whenever you buy fabric online, that you buy a swatch first because computer monitors can give a tint to the color that it doesn't have in real life. Also, please be aware that different fabrics will give you a different level of color saturation. Hence, a swatch on the fabric you intend to use is a good idea.
