When Do You Need to Install New Cabinet Hinges?
Installing new cabinet hinges can solve several problems including the ones below:
- Your cabinet doors don’t remain fully closed.
- Your doors hang crookedly.
- One or more of your hinges is broken.
- You’re installing new cabinets.
- You’re installing new cabinet doors.
In addition, if you have surface-mount hinges that are visible on the cabinet door exterior, you may want to replace the hinges to change the look of your kitchen.
Hinge Types for Cabinet Construction Types
To install the right cabinet hinges, you first need to know if your cabinets have a framed or frameless construction. There are different hinge types for cabinets with different constructions.
Face-Frame Cabinets
Framed construction is the most common for cabinets in the US. As the name suggests, framed or face-frame cabinets have a structure — the frame — fastened to the cabinet box edges, partially covering the front opening of the box. Door hinges on framed cabinets attach to this front frame. You’ll install face frame hinges that attach to the frame.
Frameless Cabinets
Frameless cabinets, European cabinets and euro-style cabinets are all terms that describe this type of cabinet construction. With no frame or structure covering the front of the cabinet box, frameless construction means the cabinet door hinges attach directly to the cabinet boxes. You’ll need to install frameless or European hinges that attach to the wall of the cabinets.
Choosing the Right Cabinet Hinges for Your Door Fit
Once you know if you need framed or frameless hinges, you need to choose between concealed and surface-mount hinges and between overlay and inset hinges.
Concealed vs. Exterior Surface-Mounted Cabinet Hinges
Concealed hinges mount to the cabinet or frame interior and door interior. The hardware isn’t visible on the exterior of the cabinet or door face. The design of this hinge type requires a hole or mortise in the cabinet door for each hinge, making installation a bit more complex than installation of surface-mounted hinges. However, concealed hinges create a sleek look and are typically adjustable, allowing you to make minor changes to the fit of the cabinet door.
Exterior surface-mounted cabinet hinges attach to the face of the cabinet and door. Installation is usually simpler than with concealed hinges since you don’t need to cut a mortise in the door. You just need to attach the hinges with screws. While simpler to install, these hinges don’t usually allow for adjustments after installation.
Overlay vs. Inset Cabinet Hinges
Hinges can be overlay hinges or inset hinges. The terms overlay and inset describe how the door fits to the cabinet box. You’ll need to select hinges that work with the fit of your doors. For example, if your cabinet doors have a 1/2-inch overlay, make sure you purchase 1/2-inch overlay hinges.
On cabinets with a full overlay, the cabinet door covers the edge of the cabinet box. The design of a full overlay hinge allows the door to open without interference from the cabinet box edge.
Inset cabinet doors install so the door faces are flush with the edge of the cabinet frames or edges, allowing this part of the cabinet to be visible. If you have this type of cabinet door, you’ll need an inset hinge to allow the door to pivot without hitting the cabinet.
You can also have partial overlay and partial inset doors as in these illustrations of exterior surface-mount hinges. As the illustrations suggest, if you have partial overlay or partial inset doors, you’ll need hinges specific to that design for the doors to open and close correctly.
Are You Replacing Cabinet Hinges or Installing Hinges for New Doors?
The process for installing cabinet hinges will vary depending on whether you’re replacing hinges on cabinets with existing doors or you’re installing hinges on new cabinet doors.
Replacing Cabinet Hinges
For replacement hinges, you should be able to find compatible new hardware. For example, if you’re replacing concealed hinges with compatible new hinges, you’ll simply need to remove the existing hardware, install the new hinges and adjust them to align and fit the door correctly. You can often use the placement of the existing hinges as a guide for the new hardware.
Installing Hinges for New Cabinet Doors
Installing concealed hinges for new doors is a bit more complex since you’ll typically need to measure for and then bore a hinge cup hole or mortise. A cabinet hinge installation jig will make this job much easier.
Installing surface-mount hinges on new doors will require a bit more measurement than replacing existing hinges, since you’ll have no existing placement to match.
Concealed Hinge Cup Size
If you’re replacing concealed hinges that require mortises, make sure you get hinges that have the same cup size as your existing hinges. A 35mm-diameter cup is the most common for kitchen cabinets, but you may also see a 26mm cup on small hinges.
How to Install Cabinet Hinges as Replacements or for New Doors
We’ll give you general steps for replacing concealed cabinet hinges below, along with variations for installing new hinges and installing external surface-mounted hinges. These steps cover common installations but always follow the instructions that come with your hinges.
For any type of cabinet hinge, it’s best to have a helper support the cabinet doors while you work. You’ll need a good work space that allows you to work on the doors without risk of damage and you’ll want to empty your cabinets before you begin.
If you have cabinet doors with a partial overlay, it’s a good idea to measure the overlay so you can reinstall the doors correctly.
