100 kinds of hinge illustrations (what are the hinge sizes and how to choose)

In our home decoration, hinges are essential hardware accessories that are commonly used when installing doors, windows, wardrobes, and fixing various items. Hinges consist of a pair of metal or non-metallic blades connected by pivot pins, usually in two folds. They provide a swinging or rotating mechanism for doors, covers, or other parts that require movement. Hinges are composed of hinge sheets, hinge shafts, hinge bearings, and hinge plugs.

There are various types of hinges available in the market, including T-type hinges, H-type hinges, core-pulling hinges, vehicle hinges, and marine hinges, among others. The dimensions of hinges vary depending on the specific requirements. Here are some common hinge sizes:

- Length * Width:

- 2 inches * 1.5-1.8 inches

- 2.5 inches * 1.7 inches

- 3 inches * 2 inches

- 4 inches * 3 inches

- 5 inches * 3-3.5 inches

- 6 inches * 3.5-4 inches

The surface treatment of hinges can also vary, such as sanding, brushed steel, brushed gold, brushed copper, sterling silver, red bronze, and green bronze, among others.

When choosing hinges, it is important to consider the weight of the door or item that the hinge will support. Heavier doors require hinges with greater weight-bearing capacity. It is also recommended to choose hinges with a metal color that matches other hinges on the door or item. For metal products like door locks, considering the quality and reputation of the brand is advisable, and the smart home industry is a promising option.

Here are some tips for choosing different types of hinges:

1. Door Hinges: The materials commonly used for door hinges are copper and stainless steel. The standard size for a single-piece hinge is usually around 10cm * 3cm and 10cm * 4cm, with a central axis diameter between 1.1cm and 1.3cm. The hinge wall thickness ranges from 2.5mm to 3mm. To ensure smooth and noiseless operation, it is recommended to choose hinges with ball bearings in the central shaft.

2. Drawer Rail Hinges: Drawer guide rails can be divided into two-section rails and three-section rails. When choosing, consider the surface paint and electroplating, gap and strength of the load-bearing wheels. The drawer hinges should provide flexibility, smooth opening and closing, and should have wear-resistant and uniformly rotating load-bearing wheels.

3. Cabinet Door Hinges: Cabinet door hinges can be detachable or non-detachable, and are further categorized based on the position of the cover after the door is closed, including large bend, medium bend, and straight bend hinges. In addition to ensuring the flatness and smoothness, pay attention to the reset performance of the hinge spring. A qualified product should have a strong supporting spring that does not deform or break when the hinge is opened to 95 degrees and pressed on both sides.

In summary, hinges are essential hardware accessories for our daily life. They can be easily found in building materials markets and hardware stores, and are available in various brands and prices. When purchasing hinges, it is recommended to choose reputable brands and consider the size, angle, surface treatment, and material of the hinge. The comparison of different options can help in making an informed decision.

Now, let's move on to the difference between medium-curved hinges, straight-curved hinges, and large-curved hinges, as well as the specifications of hinges.

The difference between these types of hinges lies primarily in their appearance and structure. The names are given based on their specific characteristics. Let's take a closer look at each type:

1. Medium-Curved Hinges: This type of hinge, also known as a half-cover hinge, is used when two doors share a side panel. These hinges require a minimum gap between the doors and have reduced coverage on each door. They are commonly used for doors that open from left to right.

2. Straight-Curved Hinges: Also known as a full-cover hinge, this type of hinge is used when the door panel completely covers the side panel of the cabinet, leaving a small gap for smooth opening.

3. Large-Curved Hinges: This type of hinge, known as a built-in hinge, is used when the door is located inside the cabinet, next to the side panel. Similar to straight-curved hinges, they require a small gap for smooth opening.

Moving on to the specifications of hinges, there are various types and sizes available in the market. Some commonly used specifications for doors and windows include 50.8*30*1, 100*60*1, 63*35*1, 101.6*76.2*2, and 88.9*88.9*3, among others. When selecting hinges, it is important to check the surface plating for smoothness, whether the spring piece's edge has been polished, and the overall weight of the hinge. Heavy hinges may hinder smooth rotation. Wooden "hukou" hinges are now rare, and most modern buildings use metal door hinges, which replace the traditional wooden hinges.

To summarize, this expanded article provides detailed information about hinges, their sizes, specifications, and how to choose the right hinge for different applications. It also explores the differences between medium-curved hinges, straight-curved hinges, and large-curved hinges, as well as the specifications available in the market. Considering these factors will help ensure the right hinge is chosen for each specific need.
