The decision of whether 4" cabinet fillers on each side are too much depends on various factors, including personal preference and the overall aesthetic you want to achieve in your space. Here are a few considerations to help you make an informed decision:
Available space: Measure the total width of your wall and subtract the combined width of your cabinets and any other fixtures that will be installed. If the remaining space is significantly larger than 4 inches on each side, you may want to consider adjusting the filler size to create a more balanced look.
Design balance: Consider the overall proportions and visual appeal of your cabinets within the context of the entire room. If your cabinets are relatively small compared to the available wall space, larger fillers could make them appear disproportionate. In such cases, reducing the filler size might be more visually appealing.
Functional requirements: Assess any functional needs that may affect the filler size. For example, if you plan to install large appliances or require extra countertop space next to the cabinets, reducing the fillers might be necessary to accommodate those requirements.
Style and aesthetics: Think about the style you want to achieve in your kitchen or space. Larger fillers can create a more substantial and visually bold look, while smaller fillers can provide a sleek and minimalist appearance. Consider the overall design theme and select a filler size that aligns with your desired style.
Ultimately, the decision regarding the size of cabinet fillers is subjective and based on your individual preferences and requirements. It's recommended to consult with a kitchen designer or contractor who can assess your specific situation and provide tailored advice based on your needs.
