Aesthetically when do you choose to a long handle or a cabinet door vs. a button size knob. This does require some finesse and doing some drawings to get it just right, but here are few tips to take into consideration. You may want to lean more towards small knobs and handles if you are going for a more contemporary style in your kitchen space. Often mixing and matching round knobs with drawer pulls work well in these style of kitchens. A longer handle may be used in a more modern kitchen for a more polished look in a space, while having too many small knobs would feel cluttered for this type of kitchen. In a transitional space, you may want to select one style of hardware and then make that one particular style of hardware larger or smaller depending on where it’s going in the kitchen. For example you would have larger handles for your refrigerator and pantry doors, but a smaller version of the same knob for the upper cabinets in your kitchen area above the refrigerator.
Let’s talk first about metals. As a general rule, I like to keep the different metals in a kitchen to no more than two. If you have stainless steel appliances, that counts as one metal. So that leaves one other metal you can bring into a kitchen. If you’ve got brass light fixtures, that’s your one other metal. Your new hardware should be nickel or brass.
