Shop Cabinet Knobs by Finish, Style and Size
Cabinet knobs are a small detail that makes a big difference. Whether you are updating a kitchen, refreshing a bathroom vanity, or adding new hardware to a dresser or furniture piece, the right knob ties the whole look together.
Inside Out Hardware carries an extensive selection of Cosmas cabinet knobs across multiple styles. Round knobs are the most popular choice for traditional and farmhouse kitchens. T-bar knobs bring a clean, modern profile to contemporary cabinetry. Ring knobs add a decorative touch that works well in classic or transitional spaces. Miniature knobs are the practical pick for smaller cabinet doors where a standard knob would feel oversized. And if you want something truly distinctive, our glass insert knobs featuring clear or amber glass are a standout option that adds elegance to any room.
With over 15 available finishes, Cosmas offers more variety than almost any other cabinet hardware brand. Popular choices include satin nickel, matte black, oil rubbed bronze, flat black, polished chrome, brushed brass, and brushed gold. Specialty finishes like graphite, gold champagne, hammered bronze, antique silver, weathered nickel, and black nickel give you even more ways to personalize your space.
Pair your knobs with matching cabinet handles and cabinet hinges for a completely coordinated cabinet upgrade.
Frequently Asked Questions About Cabinet Knobs
Most cabinet knobs range from 1 inch to 1.5 inches in diameter. The most common size used in kitchens and bathrooms is 1.25 inches, which provides a comfortable grip without overwhelming the cabinet face. Miniature knobs at around 1 inch work well for smaller doors, while larger decorative knobs can measure up to 1.75 inches for a bold statement look.
A common approach is to use cabinet pulls on drawers for easy one-hand opening and cabinet knobs on doors for a cleaner, more traditional look. However, this is purely a personal choice. Many modern kitchens use pulls throughout for a sleek, consistent appearance, while traditional kitchens often stick with knobs on all doors and drawers for a classic feel.
Matte black is the top trending finish for modern kitchen cabinet knobs in 2026, followed closely by satin nickel and brushed gold. Matte black pairs well with white, gray, or navy cabinetry. Satin nickel is the most versatile all-around option. Brushed gold is gaining popularity in transitional and glam-style kitchens as a warm, luxurious alternative to chrome.
