Restoration Hardware. 6 inch pulls, 1 1/4 inch knobs. But here is what we always do. The hardware needs to be scaled to the cabinets. Knobs should vary depending on the width of the stile and rail of the cabinet door. Drawers are harder, if the drawer is wide and deep even a 6 inch pull can look under scaled. We always buy sample in different sizes to look at before ordering all the hardware.

Thank you so much. Those are the exact sizes and brand we chose, so pretty to see it installed!
