3-Inch Door Hinges for Interior Doors & Cabinets
3-inch hinges provide a compact hardware option for interior doors, cabinetry, and other compatible applications where a smaller hinge is appropriate. The current Coastal Hardware Store assortment includes 3" x 3" residential door hinges along with narrower 3" x 2" and 3" x 2-1/2" solid-brass cabinet hinges, giving shoppers several configurations within the same 3-inch height category.
The verified products currently represented in this collection are manufactured by Deltana and include both steel and solid-brass construction. All of the current relevant models use square corners, while material, width, thickness, screw requirements, finish selection, and intended application vary by model. For additional sizes and configurations, browse our door hinges.
Why Choose 3-Inch Door Hinges?
A 3-inch hinge can be useful when the door or cabinet requires a smaller hinge footprint than common larger residential and architectural hinge sizes. Choosing the right model requires more than matching the height, since width, thickness, material, and intended use can differ considerably among 3-inch hinges.
- Compact hinge size: A 3-inch height provides a smaller footprint for compatible interior doors, cabinets, and other appropriately sized applications.
- Multiple widths: The current assortment includes 3" x 2", 3" x 2-1/2", and 3" x 3" configurations.
- Door and cabinet options: Current products include a residential steel door hinge as well as solid-brass hinges and cabinet-specific ball-tip designs.
- Steel and solid-brass construction: Shoppers can compare different base materials rather than assuming every hinge in the size category is constructed the same way.
- Square-corner preparation: The current relevant Deltana hinges all use square corners for compatible square-corner mortises.
- Broad finish selection: Current Deltana models are offered across brass, nickel, chrome, bronze, black, PVD, and unlacquered finish options depending on the product.
Types of 3-Inch Hinges Available
3" x 3" Residential Door Hinges
The Deltana Residential 3" x 3" Square Corner Hinge is a standard-weight steel hinge intended for typical residential interior-door applications. It measures .085 inch thick and uses #9 x 3/4-inch wood screws. This model provides a straightforward option when an existing door preparation calls for a 3" x 3" square-corner residential hinge.
3" x 3" Solid-Brass Hinges
The collection also includes a separate Deltana 3" x 3" Square Corner Hinge manufactured from solid brass. Deltana specifies this model at .097 inch thick with #10 x 1-inch wood screws. Although it shares the same overall 3" x 3" dimensions as the residential steel model, the different material, thickness, and screw specification mean the two should not automatically be treated as interchangeable.
3" x 2" Cabinet Hinges
The Deltana 3" x 2" Hinge with Ball Tips is classified by the manufacturer as a solid-brass cabinet hinge. It uses square corners, six hinge holes, a .125-inch thickness, and #7 x 3/4-inch wood screws. Decorative ball-tip finials are standard on this model. Because it is narrower than a 3" x 3" hinge and intended for cabinet applications, confirm both the dimensions and application before ordering.
3" x 2-1/2" Cabinet Hinges
The Deltana 3" x 2-1/2" Hinge with Ball Tips provides another solid-brass cabinet option. Like the 3" x 2" version, it has square corners, six hinge holes, a .125-inch thickness, #7 x 3/4-inch wood screws, and decorative ball-tip finials. Its additional width makes it a distinct size rather than a direct replacement for the narrower 3" x 2" model.
How to Choose the Right 3-Inch Door Hinge
Begin by confirming that 3 inches is the required hinge height, then compare the width, thickness, material, corner style, screw pattern, and intended application. A hinge that matches only the height may still be incompatible with the existing door, cabinet, or mortise preparation.
- Measure height and width: Determine whether your project requires a 3" x 2", 3" x 2-1/2", 3" x 3", or another specific hinge size.
- Identify the application: Distinguish between hinges intended for residential doors and manufacturer-classified cabinet hinges before choosing by appearance or size.
- Check leaf thickness: Current models range from .085 inch to .125 inch thick. Differences in thickness can affect how the hinge fits an existing mortise.
- Confirm the corner style: The current relevant products use square corners. Match the hinge to a square-corner mortise or account for any preparation changes required.
- Review the base material: Current 3-inch products include steel and solid-brass construction. Finish color alone does not identify the underlying material.
- Compare mounting details: Screw size and hinge-hole configuration differ by model, so use the individual specifications when replacing existing hardware.
Materials, Styles & Finishes
The current 3-inch Deltana hinge assortment includes both steel and solid-brass construction. The residential 3" x 3" square-corner hinge is manufactured from steel, while the separate 3" x 3" model is solid brass. The 3" x 2" and 3" x 2-1/2" ball-tip cabinet hinges are also solid brass. Because products with the same nominal height can have different construction and intended applications, review the exact material specification before ordering.
Current Deltana options across this collection are shown in finishes including Antique Brass, Antique Nickel, Brushed Brass, Brushed Chrome, Brushed Nickel, Oil Rubbed Bronze, Paint Black, Polished Brass, Polished Chrome, Polished Nickel, PVD Polished Brass, and Unlacquered Brass. Finish availability varies by hinge. When coordinating hinges with knobs, levers, cabinet hardware, or other visible components, use the exact manufacturer finish designation rather than assuming similarly named finishes will match.
Featured 3-Inch Hinge Options
The current relevant assortment includes four Deltana hinge configurations with a 3-inch height. Each serves a somewhat different application or construction preference.
- 3" x 3" Residential Steel Hinge: A standard-weight square-corner steel hinge intended for typical residential interior doors.
- 3" x 3" Solid-Brass Hinge: A square-corner hinge with solid-brass construction and a different thickness and screw specification from the residential steel model.
- 3" x 2" Solid-Brass Cabinet Hinge: A narrower square-corner cabinet hinge with ball-tip finials and .125-inch-thick leaves.
- 3" x 2-1/2" Solid-Brass Cabinet Hinge: A wider ball-tip cabinet hinge that retains the same 3-inch height and .125-inch thickness.
If your project requires a larger residential hinge or a different corner preparation, browse the complete door hinge collection or compare other sizes such as our 3-1/2-inch door hinges.
Installation & Compatibility
Hinge compatibility depends on the complete specification rather than height alone. Before ordering a replacement, measure the existing hinge's height, width, and leaf thickness and compare the corner shape, mounting-hole arrangement, screw size, and intended application with the new hinge.
The current 3" x 3" residential steel Deltana hinge is .085 inch thick and uses #9 x 3/4-inch wood screws, while the solid-brass 3" x 3" model is .097 inch thick and uses #10 x 1-inch wood screws. The 3" x 2" and 3" x 2-1/2" cabinet hinges are .125 inch thick and use #7 x 3/4-inch wood screws. These differences matter when fitting a hinge into an existing mortise.
Do not assume that a 3-inch cabinet hinge is appropriate for a full-size door simply because the dimensions appear suitable. Door size, weight, construction, frequency of use, required hinge quantity, and other project specifications can affect the correct hardware choice. Where those requirements are not stated for a particular product, confirm suitability before installation.

Frequently Asked Questions About 3-Inch Door Hinges
What does 3-inch door hinge mean?
In this collection, 3 inches refers to the hinge height. Current relevant products include 3" x 2", 3" x 2-1/2", and 3" x 3" configurations. Always check both the height and width because two hinges with the same 3-inch height may have very different proportions and applications.
Are 3-inch hinges suitable for interior doors?
Some are. The current collection includes a Deltana 3" x 3" residential steel hinge intended for typical interior-door applications. Other 3-inch products in the collection are classified by Deltana as cabinet hinges, so choose according to the manufacturer's intended application rather than size alone.
Are all 3-inch hinges made from solid brass?
No. The current assortment includes both steel and solid-brass construction. The Deltana residential 3" x 3" hinge is steel, while the separate 3" x 3" hinge and the current 3" x 2" and 3" x 2-1/2" cabinet hinges are solid brass.
What is the difference between a 3" x 3" and 3" x 2-1/2" hinge?
Both have a 3-inch height, but their widths differ. The current 3" x 3" products are offered as residential-style door hinges, while the current 3" x 2-1/2" ball-tip model is classified by Deltana as a cabinet hinge. Material, thickness, screws, and other specifications also differ by model.
What finishes are available for 3-inch hinges?
Current Deltana options across the collection include Antique Brass, Antique Nickel, Brushed Brass, Brushed Chrome, Brushed Nickel, Oil Rubbed Bronze, Paint Black, Polished Brass, Polished Chrome, Polished Nickel, PVD Polished Brass, and Unlacquered Brass. Not every finish is available on every hinge.
How do I replace an existing 3-inch hinge?
Measure the existing hinge's height, width, and thickness, then compare its corner style, screw pattern, screw size, and intended application with the replacement. Matching only the 3-inch height does not guarantee that the hinge will fit the existing preparation.
