gtag('config', 'AW-654510316'); When it comes to door hardware, stainless steel door hinges are a top choice for both residential and commercial applications. Not only do they offer strength and durability, but they also provide excellent resistance to rust and corrosion—making them ideal for indoor and outdoor use.
But one question that often comes up is: What sizes do stainless steel door hinges come in?
In this guide, we’ll break down the most common sizes, types, and tips for choosing the right hinge for your project.
Why Stainless Steel Hinges Are the Best Choice？
Unlike brass or mild steel hinges, stainless steel provides:
• Rust & Corrosion Resistance
• Strength under Load
• Low Maintenance Requirements
• Fire and Heat Resistance
• Compatibility with Modern Architectural Styles
Ideal for coastal areas, bathrooms, kitchens, and exterior doors.
Stainless Steel vs. Other Materials
| Material | Rust Resistance | Strength | Cost | Maintenance |
| Stainless Steel | ⭐⭐⭐⭐⭐ | ⭐⭐⭐⭐ | $$ | Low |
| Brass | ⭐⭐ | ⭐⭐ | $$$ | High |
| Zinc Alloy | ⭐ | ⭐ | $ | Low |
| Mild Steel | ⭐ | ⭐⭐⭐ | $$ | High |
Types of Stainless Steel Hinges (And When to Use Them)
Choosing the right size also means understanding the hinge type. Here’s a breakdown:
1.Butt Hinges
• Most common for doors • Mortised into the door and frame • Available in fixed-pin and loose-pin varieties
2.Ball Bearing Hinges
• Designed for heavy or high-traffic doors • Smoother, quieter operation • Recommended for 40mm+ thick solid wood or entry doors
3.Spring Hinges
• Ideal for self-closing doors (kitchen, garage, fire-rated) • Often used in pairs with a ball-bearing hinge
4.Concealed Hinges
• Not visible when the door is closed • Mostly for cabinets or interior flush doors
5.Pivot Hinges
• Mounted at the top and bottom of the door • Perfect for very heavy or full-height doors
Stainless Steel Door Hinges Sizes Chart
The table below summarizes standard hinge sizes commonly used in residential, commercial, and industrial applications:
Stainless Steel Door Hinges Sizes Chart (Metric & Imperial)
| Hinge Size (inches) | Hinge Size (mm) | Door Thickness | Common Application |
| 3” × 3” | 76mm × 76mm | 30–35mm | Light interior doors, closets, cabinets |
| 3.5” × 3.5” | 89mm × 89mm | 35–40mm | Standard room doors, bathroom doors |
| 4” × 4” | 102mm × 102mm | 40–45mm | Main entry doors, solid wood or MDF doors |
| 4.5” × 4.5” | 114mm × 114mm | 45–50mm | Heavier doors, external doors, office entry |
| 5” × 5” | 127mm × 127mm | 50mm+ | Security doors, industrial metal doors |
How to select hinge size?
Choosing the right hinge size depends on four key factors:
1.Door Height
• Doors under 2100mm (7 feet) typically require two or three hinges.
• Doors taller than 2100mm may need three to four hinges to prevent sagging and ensure long-term durability.
2.Door Thickness
A general rule of thumb:
| Door Thickness | Suggested Hinge Size |
| 30–35mm | 3” or 3.5” |
| 36–40mm | 3.5” or 4 |
| 41–45mm | 4” or 4.5 |
| 46–50mm | 4.5” or 5” |
| 51mm+ | 5” or custom size |
Thicker doors require larger hinges to support increased weight and ensure smooth operation.
3.Door Weight & Material
• Solid wood or metal doors are heavier and require ball bearing or heavy-duty hinges.
• Hollow core or MDF doors are lighter and can use standard butt hinges.
4.Door Width
Wider doors exert more leverage on hinges. For every additional 150mm in width, consider upsizing the hinge or adding a third or fourth hinge for support.
Installation Tips for Stainless Steel Hinges
1.Number of Hinges
| Door Height | No. of Hinges |
| Up to 2100mm (7 ft) | 2–3 |
| 2100mm–2400mm | 3 |
| Over 2400mm | 4 |
2.Placement on the Door
• Top hinge: 125–180mm from the top of the door • Bottom hinge: 180–250mm from the bottom • Middle hinge(s): Evenly spaced between the top and bottom hinges
3.Hinge Screw Selection
Use stainless steel screws that match hinge finish. Ensure length is sufficient to penetrate door and frame (typically 25mm–40mm screws).
When to Use Heavy-Duty Stainless Steel Hinges？
Choose heavy-duty or ball bearing stainless steel hinges when:
• Door weight exceeds 40 kg (88 lbs)
• Door height exceeds 2100mm
• Door is used frequently (high-traffic zones)
• Door is exposed to moisture or chemicals
• Enhanced security or fire resistance is required
Frequently Asked Questions
What Size Hinge for a 40mm Thick Door?
A 40mm thick door is common in modern construction, especially for residential bedroom, bathroom, or main entry doors.
Recommended Hinge Size for 40mm Door:
• Minimum: 3.5” × 3.5” (89mm × 89mm)
• Optimal: 4” × 4” (102mm × 102mm)
• Heavy Door: 4.5” ball bearing hinge for solid wood or exterior doors
Also consider hinge gauge (thickness):
• For residential use: 2.5mm–3mm hinge thickness
• For commercial or heavy-duty use: 3.5mm–4mm
What are standard hinge sizes?
Usually used for doors, common sizes include 4 inches × 4 inches (about 102mm × 102mm), 4.5 inches × 4.5 inches (about 114mm × 114mm), 5 inches × 5 inches (about 127mm × 127mm), etc. There are also some non – square sizes, such as 4.5 inches × 4 inches (about 114mm × 102mm), 5 inches × 4.5 inches (about 127mm × 114mm).
Are hinge holes standard?
The installation hole diameter of industrial hinges is determined according to the load – bearing capacity and screw specifications. Light – duty industrial hinges with a load – bearing capacity of less than 50kg commonly use M4 and M5 screws, and the corresponding installation hole diameters are 3.2mm and 4mm, respectively; medium – duty industrial hinges with a load – bearing capacity of 50 – 100kg mostly use M6 and M8 screws, and the installation hole diameters are 4.8mm and 6.4mm, respectively; heavy – duty industrial hinges with a load – bearing capacity of more than 100kg require the use of M10 and above screws, and the installation hole diameters are 8mm and above. The hole diameter tolerance of industrial hinges is usually controlled within ±0.1mm.
