Knowing how to measure door hinges correctly is essential for both homeowners and professionals when replacing, upgrading, or installing new doors. Accurate measurements ensure smooth door movement, proper alignment, and long-lasting durability. Whether for residential, commercial, or hotel projects, choosing the right hinge size and type is key to ensuring safety and functionality.
As a professional B2B door hinge manufacturer, we specialize in producing high-precision stainless steel and brass door hinges, offering OEM and custom solutions for construction, hotel, and architectural projects worldwide. In this guide, we’ll explain how to measure door hinges properly and why our products provide a reliable and durable solution for every installation.
A door hinge is a mechanical bearing that connects a door to its frame, allowing it to swing open and close smoothly. The hinge must be chosen according to the door’s size, weight, and usage frequency.
| Type | Description | Common Applications |
|---|---|---|
| Butt Hinge | The most common type, consisting of two leaves joined by a pin. | Interior and exterior wooden doors |
| Concealed Hinge | Hidden within the frame for a clean appearance. | Modern cabinets, premium doors |
| ball bearing hinge | Uses ball bearings for smooth, silent operation. | Heavy-duty or frequently used doors |
| Spring Hinge | Automatically closes the door after opening. | Fire-rated or security doors |
| Continuous (Piano) Hinge | Extends the full length of the door. | Commercial, metal, or cabinet doors |
Understanding which hinge type you’re using will help determine the correct measuring process and material requirements.
Before starting, prepare the following tools:
Measuring tape or ruler (preferably in millimeters for precision)
Caliper (for accurate thickness measurement)
Screwdriver (if removing existing hinges)
Notebook or phone to record your measurements
Tip: If replacing an old hinge, always measure the existing one rather than relying on door specifications — hinge sizing can vary by brand or region.
Lay the hinge flat on a surface and measure from top to bottom.
The height typically ranges from 76mm (3 inches) for light doors to 127mm (5 inches) or more for heavy commercial doors.
Ensure both hinge leaves are fully extended during measurement.
| Door Type | Recommended Hinge Height |
|---|---|
| Interior wooden doors | 76mm–100mm |
| Exterior solid doors | 100mm–127mm |
| Metal or fire-rated doors | 100mm–150mm |
Measure from one edge of the open hinge to the other, across both leaves when fully extended.
This determines how far the door will open and how much load the hinge can support.
Typical widths range from 50mm to 100mm, depending on hinge type.
| Hinge Width | Suitable Door Type |
|---|---|
| 50–70mm | Lightweight doors |
| 75–90mm | Standard wooden doors |
| 100mm+ | Heavy or security doors |
Use a caliper to measure the thickness of one leaf.
Thicker hinges (3mm–4mm) are designed for heavy-duty doors.
Thinner hinges (2mm–2.5mm) are adequate for lightweight or interior doors.
| Thickness | Recommended Use |
|---|---|
| 2.0–2.5 mm | Standard interior doors |
| 3.0–3.5 mm | Heavy wooden or metal doors |
| 4.0 mm+ | Industrial or fire-rated doors |
If you’re replacing an existing hinge, measure the distance between screw holes to ensure compatibility with existing frames. Record both horizontal and vertical distances.
Check if the hinge corners are square or rounded:
Square corners (90°) are common in commercial applications.
Radius corners (1/4” or 5/8”) are often used for pre-hung doors.
Matching the corner style ensures a seamless fit without the need for extra trimming or routing.
Material selection plays a vital role in performance, aesthetics, and lifespan. As a B2B door hinge supplier, we provide multiple material options to meet diverse architectural needs.
| Material | Characteristics | Ideal Applications |
|---|---|---|
| Stainless Steel (SUS304 / SUS316) | Corrosion-resistant, durable, suitable for outdoor and humid environments | Hotels, villas, marine projects |
| Brass | Elegant appearance, smooth operation, long lifespan | Luxury doors, decorative installations |
| Iron / Steel (Powder Coated) | Strong and economical | Standard construction projects |
| Zinc Alloy | Lightweight and cost-effective | Interior wooden doors |
| Aluminum Alloy | Anti-rust, light-duty applications | Modern interior projects |
Our stainless steel hinges are the most popular choice for B2B clients because they offer exceptional strength, weather resistance, and long-term value, making them ideal for large-scale hotel or commercial installations.
