When selecting cabinet hinges, many buyers focus on opening angles, soft-close functions, or installation methods. However, one of the most important specifications in cabinet construction is the door overlay configuration.
Terms such as Full Overlay, Half Overlay, and Inset determine how the cabinet door sits in relation to the cabinet side panel. Choosing the wrong hinge type can lead to door collisions, inconsistent gaps, difficult installation, and expensive production errors.
This guide explains the three major cabinet hinge overlay types and helps furniture manufacturers, distributors, and cabinet designers select the correct solution for each application.
Quick Comparison Table
Hinge Type
Door Position
Cabinet Appearance
Typical Application
Full Overlay
Door fully covers cabinet side
Modern seamless appearance
Kitchens, wardrobes
Half Overlay
Two doors share one side panel
Space-saving layouts
Double-door cabinets
Inset
Door sits inside cabinet frame
Flush and traditional look
Premium furniture
What Does Overlay Mean?
Overlay refers to the amount of cabinet side panel covered by the cabinet door after installation.
The hinge arm geometry determines how far the door sits from the cabinet body.
A larger overlay creates a cleaner and more modern appearance, while smaller overlays leave more of the cabinet structure visible.
Full Overlay vs Half Overlay vs Inset Comparison
Full Overlay Hinges
Full overlay hinges allow the cabinet door to cover almost the entire cabinet side panel.
This is the most common hinge configuration used in modern modular kitchens, wardrobes, and bathroom cabinets.
Advantages
Modern appearance
Minimal visible gaps
Larger door coverage
Excellent dust protection
Compatible with soft-close systems
Typical Applications
Kitchen cabinets
Wardrobes
Bathroom vanities
Contemporary furniture
Most 35mm concealed hinges used worldwide are designed for full overlay applications.
Half Overlay Hinges
Half overlay hinges are used when two cabinet doors share a single center partition.
Each door covers approximately half of the side panel.
This arrangement allows both doors to operate independently while maximizing storage capacity.
Advantages
Efficient use of cabinet partitions
Reduced material consumption
Suitable for multi-door cabinets
Lower overall cabinet width requirements
Typical Applications
Double-door cabinets
Storage units
Office furniture
Utility cabinets
Half overlay hinges are often called cranked hinges or half crank hinges depending on the local market terminology.
Inset Hinges
Inset hinges position the cabinet door completely inside the cabinet opening.
The door sits flush with the front edges of the cabinet.
This design requires greater manufacturing precision because the door gaps must remain consistent on all sides.
Advantages
Premium appearance
Traditional furniture styling
Protected door edges
Flush cabinet front
Challenges
Higher manufacturing accuracy required
Smaller adjustment tolerance
More difficult installation
Higher production costs
Inset doors are frequently used in:
Luxury kitchens
Solid wood furniture
Traditional cabinetry
High-end custom projects
How Hinge Arms Create Different Overlays
The difference between these configurations does not come from the cup diameter.
Most concealed hinges still use a standard 35mm cup.
The difference lies in the hinge arm geometry:
Straight arm → Full overlay
Medium crank arm → Half overlay
Large crank arm → Inset
Because of this, many manufacturers classify these hinges as:
Straight Arm Hinge
Half Crank Hinge
Full Crank Hinge

The correct selection depends on cabinet construction rather than hinge quality.
A full overlay hinge is not “better” than an inset hinge. Each configuration solves a different engineering problem.
Frequently Asked Questions
Is full overlay better than inset?
Not necessarily. Full overlay provides a modern appearance and easier installation, while inset offers a premium flush appearance that requires higher manufacturing precision.
Can I use a full overlay hinge on an inset door?
No. The hinge arm geometry is different. Using the wrong hinge type will cause improper door positioning and poor alignment.
Are all three hinge types available with soft-close functions?
Yes. Modern hydraulic concealed hinges are available in full overlay, half overlay, and inset versions.
Do these hinges use the same cup size?
Most concealed cabinet hinges use a standard 35mm cup diameter regardless of the overlay type.
Which overlay is most common worldwide?
Full overlay hinges dominate modern kitchen and wardrobe manufacturing because they provide a clean appearance, larger adjustment ranges, and simplified production.
Conclusion
Understanding overlay configurations is essential for selecting the correct cabinet hinge.
Full overlay provides maximum door coverage and modern aesthetics.
Half overlay allows multiple doors to share a partition.
Inset creates a premium flush appearance.
By selecting the proper hinge geometry during the design stage, manufacturers can improve assembly efficiency, reduce installation errors, and achieve consistent cabinet performance.
