Designing your knob scheme can be a challenge, especially when there are so many wonderful choices! You should always consider the drawer size and cabinet paneling when selecting the appropriate diameter.
A handy little trick is to place paper cutouts in various sizes on doors and drawers. Our Poppy knobs are shown in 3 sizes; 2.5", 2" and 1.5" diameters. Don't be shy about combining the sizes. Bathroom cabinets and bedroom dressers typically have various drawer sizes. Also consider the contents and weight of the drawers when making your selection. Double up on up lengthy drawers and use two knobs or handles.
