The decision of whether kitchen cabinet hardware should match appliance handles is a matter of personal preference and style. There is no hard and fast rule that dictates they must match. However, many people do choose to coordinate the finishes of their hardware and appliance handles to create a cohesive look in the kitchen.
Matching hardware can create a sense of unity and visual harmony in the space. For example, if you have stainless steel appliances with brushed nickel handles, you might consider using brushed nickel hardware for your kitchen cabinets to create a cohesive and consistent aesthetic.
On the other hand, some people prefer to mix and match finishes for a more eclectic or contrasting look. This can add visual interest and create a unique design statement. For instance, you might choose to have oil-rubbed bronze hardware on your cabinets while your appliances have stainless steel handles.
Ultimately, the decision should be based on your personal taste and the overall style you want to achieve in your kitchen. Consider factors such as the colors, materials, and finishes of other elements in the kitchen, such as the backsplash, countertops, and lighting fixtures, to ensure a balanced and coordinated design.
